#1 Mistake DIY Painters Make (How to paint over oil based paint)

- In this video I’ll show you the results of painting water based paint over oil based paint. There’s a simple trick anyone can use to identify water based vs oil based paint and avoid making the mistake I made on this job site that I won’t forget. I’ll show you with examples in this video.
I also cover this mistake on my website at:
notwaitingtolive.com/how-to-p...
This is the biggest mistake to avoid as a painter. Water based paint adheres poorly to oil based paint without an oil based primer and comes off with just a gentle scratch of a fingernail. Peeling on doors can start within days.
I read a horror story where a woman took the time to repaint all of the interior doors for her house. She used a water based paint over an oil based paint and had to scrape and repaint every door within a week due to immediate peeling.
The easiest way to determine whether you’re about to paint over water based paint or oil based paint is to remove a small sample.
How do you remove water based paint? Water based paint is removed remarkably easily using denatured alcohol.
How do you remove oil based paint? Oil based paint is removed using either mineral spirits, paint thinner, acetone, or paint stripper. Mineral spirits can be found in an odorless variety and does a good job of removing fresh oil based paint, but doesn’t work as well as the heavier duty noxious chemicals like acetone or paint stripper. For old, difficult to remove oil based paint, the best bet is to use acetone or paint stripper. However these will leave a sticky residue, unlike removing water based paint with denatured alcohol which leaves no residue.
How do you paint over oil based paint? Oil based paint adheres well to other oil based paints. If applying water based paint over oil based paint, an oil based primer like Kilz Original works well. Even though the primer is oil based, it’s designed to bond to water based paints.
I’ve used Kilz oil based primer in the past to paint over wall paper and varnish and polyurethane for great results.

What's the best way to wrap an extension cord? czcams.com/video/NUIwDFIHvDI/video.html
I need to remove oil based paint from several walls throughout a home. It was applied unevenly and paint streaks are visible everywhere. In your video, you discuss using denatured alcohol, paint thinner and acetone to remove oil based paint. Is this an difficult job, requiring a lot of scraping and repeated reapplication of the solvents in order to remove it all, or does it come off the wall relatively easily? When it comes off, is it also removing the texture?
Expensive lesson! Nothing is more fun than doing a job twice, and taking three times as long. Thanks for the freebie!
You're welcome. It was a painful lesson for sure. There will be more, just gotta remember to learn the lesson the first time.
Haha I experienced this yesterday. Big mistake. Now to rectify it! Can I just sand it down and not use primer?
At 3:26 when he said "A good feature of oil-based paint is that it's easy to clean with just soap and water", he was referring to cleaning the surface of dry oil-based paint, not cleaning your brushes or tools. Oil-based paint requires paint thinner for cleaning brushes and tools. Just wanted to clarify for those who are watching who may not have understood.
Matt Mason great point to clarify. Cleaning up the actual oil based paint itself is a pain. And disposing of paint thinner correctly is an even bigger pain. The wasted thinner/paint mess needs to dry before being disposed in the normal trash and the remaining thinner has to be saved or disposed at a special water facility.
@@notwaitingtolive I'm learning a lot from these comments, thx guys!
@@notwaitingtolive tell me about it :(
@@notwaitingtolive its not that bad its easier to clean oil based or solvent based paint out of brushes than it is water you just store your brushes in water you dont need to clean them out straight after and you dont throw your white spirit away you recycle it and reuse it for cleaning and burning out kettle and scuttles etc its only bad for the environment if you dont know what your doing.
Great short informative video. Exactly the answers I needed. Thank you so much.😊
Thankyou! I appreciate you sharing this with us. I'm moving into a house with oil-based painting, and I wanted to make sure I don't buy the wrong paints or miss a step when repainting.
Thank you so much! This has been the clearest explanation and fix-it I’ve found. I’ve been searching for hours.
You’re welcome. I’m glad you found this helpful. What problem have you run in to?
me too, straight forward no nonsense and shows while explaining, thx guy
Thank you so glad I adrenal this about to work on a DYI. As well as my trim and borders. My husband was a painter and I have not a clue. But must say you gave in site as to cleaning the walls better. Thanks.
You're welcome. I'm glad you found this useful.
short and to the point! Thank you sooooo much!
Thank you , I was looking for this as I need to repaint my wall.
Thanks! Very helpful and concise
This was so helpful. I started painting a wall and saw it doing what you showed. I thought it might be an oil-based paint and I'm glad I saw this. Thanks!
cubbiesrul you’re welcome. Glad you caught it early. When you’re using chemicals or scraping make sure to wear a mask!
Same !
Thank you for the great explanation. Very helpful.
Glad you found it helpful. Thanks for taking the time to leave feedback.
Thank you for your videos. You save me from making a big painting mistake!
You're welcome. Glad you caught it in time!
Sadly, I just made this same mistake. Thanks for your video - no one else showed what it was like to make the mistake and how to fix it.
So glad I saw this was about to get a painter to do the exact thing you did Whew...... Glad you did this video!!!
Corvette W.S. Glad this helped you out. This little detail can cause a massive headache.
Thank you so much. This was exactly our problem. I now understand.
The good news is there’s a solution and you’ll work through the problem. Thank you for stopping by to let us now you found this helpful. That means a lot to me.
Yep very helpful thx for explaining it all and now I know how to fix my walls
Thank you for postiing this video. It's the only one I've found that teaches a test - denatured alcohol - to know if one's deailing with oil based paint on walls or trim. I'm informed!!!.
You're welcome. I appreciate you taking the time to leave feedback. This was a shortcut I learned the hard way!
Brilliant tips, probably saved me a lot of time!
Thank you! This is a painful mistake! I appreciate you taking the time to leave feedback.
Hey there! Thanks! This is very helpful
Thanks never thought of this... perfect since im about to repaint the whole house now i lnow what to look for
izz5946 if it ends up saving you time, it ends up saving a lot of time. I read a horror story online where a person covered all their doors with a water based paint on top of an oil based paint. They had to scrape every door and repaint them all within a week.
@@notwaitingtolive so initially paining rental walls would you use water or oil based paint in the beginning.......
Very helpful video, thanks!
You’re welcome.

Thank you so much. yes, you are right, it does take longer to dry and has a stronger odor. The information you have given is helpful. 👍

Super helpful! Thanks man
You’re welcome. Thank you for the positive feedback. I appreciate it.
Thank you
I had some "pro painters" paint with latex paint over doors and trim that had always been painted with oil-based paint. They promised they had prepped the surfaces for painting, but they had not. I recognized the problem pretty quickly and got rid of those painters before they could ruin more of the paint on the existing trim, doors and walls that were originally painted before WWII with oil- based paint. Since then I have been looking for an easier solution than trying to sand off their work.
I hope your tip about using denatured alcohol will work for me. The latex paint can look good, as long as it is never touched. When it receives the slightest scratch, up it comes. Oil-based paint has such a hard finish that in older houses, like mine, the wood work loses moisture and shrinks inside the hard shell of the paint, and ultimately debonds from shrinkage. Once you crack that hard shell and see what has happened over 40 or 60 years, or longer, you end up having to remove a lot of debonded paint, sand it down and start with an oil-based primer, etc., and you have to worry about lead particles in the air, HEPA vacuum cleaners, and getting an industrial grade gas mask in today's Covid-19 environment, where they are hard to find or afford.
Thanks for sharing your experience and the solution to the problem with your viewers.
I appreciate your feedback on your experience with oil based paint. That's frustrating that you now have to correct their mistakes. I've flipped a couple 100 year old houses and noticed the cracking you describe where the wood shrinks inside the hard shell of the oil based paint and cracks. It was most prevalent on the interior window casing. I actually replaced some of the trim to avoid the tedious refinishing you described.
When you're using the denatured alcohol I'd have multiple fans moving air out of the room. The fumes are pretty harsh after a while. I'd also recommend a cheap chemical odor mask (although I have no idea if you can even buy them at the store these days due to coronavirus demand).
The denatured won't take off every little bit but it will take off what's weakly bonded in the first place. A light sanding with 100-grit can knock down whatever else needs to come off. Then the primer you use will lock in the rest. The job from this video was completed 10 months ago and has no apparent issues.
ty good info....well tought
Awesome!
Great video
Thank you!!
Wow. VERY HELPFUL!
A painter did this to all 18 interior doors of our house--PLUS the trim. Didn't charge for his destruction. 😤
I'm guessing we need to replace all of them and start from scratch. Over-sprayed onto some of the walls too.
Glad you found this useful. In this video I wiped off the door and trim with denatured alcohol. But that would be quite a lot of chemical exposure in your situation. I have heard of people light sanding (keying) the surface with ~100 grit sand paper then priming the surface with an oil based primer. That’s still a lot of sanding. You just want to make sure you sand off everything that comes off easy. And then dust the surface before painting.
Whatever you do: Stay positive. That’s the only way to get through a task like this. The good news is that there is a solution.
THE same thing with our house...the previous home owners painted over EVERY DOOR and TRIM in ALL rooms from the kitchen to the bedrooms and bathrooms, and hallway trim...everything!!!
It has been a disaster...how do we convince a contractor to take over this tedious task???
Very helpful
This guy has GREAT tips!
Thank you! Your positive feedback means a lot to me.
Thanks a lot. another tip is to use fine grade sandpaper to prepare the surface before
Great tip. And I agree that's a good, simple, and fast solution. I'm sure people reading the comments will find that helpful.
Another type of primer I use is shellac based BIN primer which would cover up oil based paint to allow people to paint with water based paint. I actually just painted a smoke damaged fireplace mantle in this video for a friend using shellac based primer and oil based paint and love how it turned out: czcams.com/video/u2pdzTiKpDY/video.html
My apartment complex did just that you did and I had to fix it as you did
That's a bummer. But at least there's a solution.
Great video thanks
You're welcome. I'm glad you found these painting tips helpful.
Thanks 🙏
Thanks Man !
Thank You!
Dania Dessine you’re welcome. I’m glad you found this useful.
Okay...man THAT explained it perfectly!! I did all the doors, trim, and windows with the damn water based over oil. I have a JOB ahead of me, but at least it give me a direction to head. I thought I may have to sand off all that water based paint as it's now several weeks dry. But I have Denatured Alcohol around. Thanks also for the detail on what primer (Oil Primer) in this case, to put down before I go over it with water based again. Man, what a hassle, but can't thank you enough....cheers!
Anthony Johnson oh man I feel your pain. You’re in a tough situation.
Make sure you wear a P100 mask if you’re going to be using this much denatured alcohol and use multiple fans to keep the room well ventilated.
If you’ve used a water based paint/primer combo paint you’re going to notice where the water based paint you applied has adhered well to the trim. I’d focus on removing what comes off easy and leave anything that needs serious elbow grease to take off. Some 100 grit sanding might help as well at this point to wear down any areas that don’t want to wipe off. And then I’d just cost over that with the oil based primer.
The job I did in this video is 8 months old now and the trim hasn’t shown any trouble yet even though I didn’t get all the water based paint off perfectly.
@@notwaitingtolive Yeah....I was thinking that about the mask..that did pop into my mind. I was also going to ask you if you used at least some medium grit sandpaper for some of the harder spots. I'm also glad you mentioned in this second post about " not getting all the water based paint off." lol....I was praying you werent going to write MUST REMOVE ALL OF IT -- OR YOU'LL BE SCREWED!! " LOL. But yeah, I really appreciate your time and insight. I'm taking one door and one base board at a time, and getting them prepped right and corrected. Can't let this job fall into chaos....and IT CAN. So thanks man, I appreciate your help...
Thanks. I was about to do that.
Catalino Vega you’re welcome. I appreciate your feedback.
Thanks great vid to the point
You're welcome. Happy to help. Thank you for taking the time to leave feedback.
Thank you so much for this video. So basically use an solvent based primer on all oil based paint before painting. Can you use solvent based primer on newly plastered walls and use a water based paint over it? Thanks so much 🙏
Good info
Thank you for making the mistake, so we do not have to. Fair play to you !
You’re welcome. I have other home improvement tips you might be interested in like the best way to wrap an extension cord: czcams.com/video/NUIwDFIHvDI/video.html
Thank you so much for this video. I had a huge fail putting water based paint over the oil based on a wall and it just kept peeling with everything touch.
You're welcome. It happens. The good news is, it's all fixable.
Prizzy krissy i just did the same thing. Dis you completely remove the water based paint that you accidentally put on before applying the primer or did you jist apply the primer directly over the mistake?
Midget0412 no, I had to remove the water based paint first .
Awesome thank you
Sand the oil coat, clean with tsp, then prime with zensser cover stain primer, and sand.
I made the mistake of painting over oil with latex paint. I did prime before but still starting to peel 😡 thanks for the tip!
The good news is it can be fixed. It’ll work out right.
Thanks! This was great. But I don’t get why painting over an oil-based primer with water-based paint would be better than paining over oil-based paint?
Primer is not the same as paint, just made out of a similar product. Primer is designed to be painted over by anything. The oil based primer is just a better primer than water based.

nice man
Damn.. Thanks for the info. I just finished painting all the trims inside and outside of my house and realized the paint inside isn't sticking correctly. Waterbased on oilbased... Well that's an expensive lesson... Haha.
You’re welcome. The good news is this is the last time we’ll make this mistake.

Oh, one other note. I couldn't understand either why the last painter put down oil based paint in an upstairs bedroom. And besides what you said about easy clean up for stains and spills, there's also the " look " that a lot of people like as far as LESS brushstrokes showing in oil based paint finishes.
So oil based paint is more forgiving, ie, hides brush strokes?
@@MK-ih6wp That's correct. I believe because oil based paint is heavier and just lays down better without brushstrokes, that is, if you're looking for the no brushstroke look. Some people like brushstrokes to show as it looks more like a grainy natural wood.
My doors and trim were all painted with water based paint over oil (prior to my home purchase). This video was quite helpful. Is there a quicker way to apply the denatured Alcohol? Can I paint it on and then rub larger areas to speed up the process?
Mary Lightfine - That's what I was wondering, but I guess we're not going to get the answer here (2yrs later) LOL!
Literally you saved me not to make the same mistake!!!!!!!!!! Oh my god! Thanks for sharing
Good vid. I like the quick test to determine if the underlying paint is water based or oil based. Do you know if all oil based paint is considered flammable/combustible and therefore require a sprayer to be grounded to avoid being shocked?
To be candid I have sprayed oil based paint out of an airless sprayer and a High Volume Low Pressure sprayer (HVLP) without grounding. But I'm not sure if that's a necessary safety precaution or not.
@@notwaitingtolive Thanks for the info.
Thanks for sharing. My boyfriend didn't believe me about the paint. But he heard this and stopped arguing with me, lol.
Lori Fulcher my own dad just the other week painted water based paint over the oil based paint I put on his steel gutters. Fortunately I was able to stop him after only 6 feet. It’s one of those things that you don’t know until it causes you pain.
I primed my bead board walls with drywall primer how can I fix this to achieve a better painted finish product?
But if I paint with oil paint. What kind of solvent should I use
To clean my paint brush?? And if acetone works to take water base paint off and to clean oil base. Is there a way that when I m testing the paint come out too?
Primer with cover stain…. Cover stain zinsser is the best!!!! And then finish with aristoshield for Dunn Edwards for kitchen and bathrooms or wood like doors and kitchen cabinets or any wood… regular walls like living rooms or bedrooms used Everest or spartawall for Dunn Edwards also….
I do love zinsser too. I have not used Dunn Edwards paints, will have to try them out.
So I cannot use any latex paint on top of cover stain by Zinser?!
Hey!! so I painted my cabinet with Nuvo kit I finished off with oil based finisher which was a mess 😢.. ??once I use an oil based primer can I use the nuvo kit again which is water based and acrylic based?
How about on the ceiling ? I used an oil based paint to cover the stain ? Can I use water paint on the ceiling since it says to paint it after?
I need help. I used Kilz interior primer on my exterior walls of my wood building. What should I do to fix this?
If I paint with pro block oil primer I can paint water based over it once dried? Also what if I used a water based primer over the oil and painted with water based paint?
I use kel-bond ultra is Water base primer instead oil base primer works wonderful 100 % Recommended
Good to know. Water based definitely is better for our health when painting.
I'm repainting some door trim that shows a lot of paint scratches and discovered water base paint was used over an oil base paint. My question is...can I prime this trim with an oil based primer and then repaint with a fresh coat of water base paint?
So glad to find you! The walls and ceilings in my house have always been painted in oil paint. I want to paint the walls again but have been informed i cant find oil paint anymore. I like oil paint as it looks mhch nicer and is easier to clean. What do you suggest i get for my walls. Can i find oil paint? Thank you for the tips.
sand down all your walls lmao
Deb I prefer oil based paint as well in a home. I agree it looks much nicer and easier to clean. But you need to have the patience for the extra dry time (up to a day or more depending on temperature and humidity) and you also need to be extra careful as you'll need to use paint thinner to clean up has drips and your brushes.
Here in Ohio oil based paint can be found at Home Depot in quarts. Other states such as Michigan still sell oil based paint in 1 and 5 gallon quantities to the public. But in other states like California I hear oil based paint is very difficult to find, perhaps even banned.
Use silk vinyl, it's water based and easy to clean
I just had a room remodeled and wonder if they used primer before painting. The doorway which they painted last seems to be bleeding something brown and gunky. Is it possible they painted over lead based paint causing this?
You could have just sanded the latex surface. I use water based primer for my oil based paint. You just have to let the primer dry for 24 hours. It will dry very slow, but as long as you give it time it's great. If you do not give it the 24 hour dry time it will lift in time.
I am here because I made this mistake
So how did he fix the problem?
Watching this video 2 days too late. I painted right over the gloss finish without any type of preparation. The result for me was the new paint dried over the gloss painted brick planter fine, but came out lighter shades of the new color. I was advised, now use a primer. I used Kilz and repainted. Same result.
I’m exploring ways to hide the planter. There's no peeling. If it peels later on, I'll be peeling, but definitely not trying a third time.
Great video and have you tried sanding the oil finish off partly with a 160 grit sandpaper, then vacuum, wipe with a clean white rag or tac cloth? A sanding sponge lightly dampened will reduce particles in the air or you can use a sanding block with a vac attachment for reduced dust. I learned a lot with an Artist for 10 years doing Ventian Plaster, Faux finish, etc.. You can see his recent works which involve a blending of old and new methods such as squashing cans, adding coins, keys, found objects, rendered in Art from Greek Mythology (JonathanBressler).
I haven’t for walls but I have sanded cabinets and railings that had oil based polyurethane before painted with positive results. I appreciate your insight. I’ve also found alcohol based primer to work well. I love using the shellac based primer to block wood tannins when painting wood for the first time to keep them from bleeding through and most recently I used it to stop a greasy wall from bleeding through.
I’d love to learn Venetian plaster, I’ve seen a couple videos of that on CZcams that are simply amazing. I love watching the lost art that some of these painters still practice, I’ll definitely look up his stuff.
I just did my whole bathroom. ceiling, 4 walls and trims... and i got this problem, so it could always be worse hahaha
If I have Oil paint already on a Wooden door frame exterior which primer would be great for me to use to apply to it so that I can do it in a new color after?
Oil based primer. If you’re going light to dark you can tint the primer grey to help block the old color.
Oh shit..I made THEE SAME mistake of painting water based over oil. The finish looks like hell. The customer is not happy. I looked up this video for help in the correct process. Ill restart the video and we what ya got for me as far as solutions. But yeah,...lol, I laughed when you said that about your error....cause I'm dealing with the same thing right now.
I have a question. My bathroom has a oil based paint that has been there for 20+ years. I am ready to paint it a color now. I bought an oil based primer and then I assume I can do that and then use a water based paint after. Am I correct?
Heather Garrison yes correct. That will work.
Can I put oil base metal paint primer on a latex paint (front door which painted 10years ago) ?
Yes. I’ve done this on my own front door. I recommend oil base paint for the front door as well due to the exposure to the elements. I also recommend a spraying a couple layers of clear coat by rustoleum to protect the paint from fading into n the sun.
Thanks for the video. I applied zinseer 123 water based primer over oil based painted kitchen ceiling- cleaned with STP, then used clean strip liquid sander deglosser. Now the primer can be remove with my finder nails. It has taken me hours and hours to scrape a small area on the 12x25 ceiling, a nightmare- denature alcohol that you used is a fuel- (1) is it dangerous to use in a kitchen ceiling? (2) would it remove just the primer and not the oil based paint?
Raymos S You have a couple options: (the long proper way) sand the ceiling and start over or (the quick fix that won’t last forever) cover the ceiling with a shellac based primer as is (imperfections and all) and roll on a joint compound texture.
Using denatured alcohol to wipe paint off the ceiling is a nightmare because the chemical is tough on your lungs and expensive. You’ll be dripping it everywhere and the scrubbing will be incredibly difficult and frustrating.
Consider using an electric pole sander like this to save you time scraping the ceiling amzn.to/35m2AHo. You’ll be able to sand the primer off without having to climb up on a ladder. Use a low grit sand paper 40-60. If the ceiling is flat and you’d like to keep it that way use caution. If you damage the ceiling you can always roll on a texture to hide the imperfections.
Covering the ceiling with joint compound is not ideal with oil based paint because the joint compound can peel and crack off. Use shellac based primer to cover the water based primer on the ceiling (shellac based primer is twice as expensive as oil based primer but has the best adhering properties) then cover the new coat of primer with joint compound (roll on and texture with proper brush). This will save you hours and hours.
My only other comment about denatured alcohol is to use a respirator for chemicals specifically for your health. I have no insight on the flammability of the liquid. It evaporates quickly. But you’ll have to do your own research on how likely it is to ignite. I just don’t know.
What are your thoughts?
@@notwaitingtolive thanks
What if the denatured alcohol does not rub the water based paint from the oil based paint? I did the exact same mistake as you. I learned the hard way.:(
Derek Hussey 1. Light sand (~100 grit) the surface and wipe off the dust with a tack cloth, doesn’t need to be perfect. (In this video I was not able to get all the water based paint off and it’s still adhering nicely a year later) 2. Apply a dedicated oil based primer over what you previously painted. 3. Apply your water based paint.
You only have to give a key ( gentle sanding )then use a water based undercoat. Done this for years no issues.
Thanks for sharing your experience.
I'm about to paint a bathroom and the paint is flaking off everywhere - ceilings, walls and door. It was likely painted decades ago. I'm wondering if sanding might be the way to go since the paint is already coming off.
I might have already answered my question but do you think the denatured alcohol is the best way to go?
Thanks so much.
Sam N I agree with your instincts on this, sand it off. Because of the large amount of surface area you’ll be tackling I recommend using some type of electric pole sander like this amzn.to/34bm6FQ. This will allow you to sand the ceilings and upper walls without getting on ladder.
Usually a 5 in 1 tool is enough to tackle small amounts of peeling and flaking in a room, but if it’s truly happening everywhere, using just this tool would be back breaking work.
Save time on the ceiling by going with a textured ceiling. Sand off the major chips and flakes and then roll on thinned down joint compound which is patterned randomly with a brush to hide all the imperfections in the ceiling.
Also with that amount of sanding make sure to wear a P100 filter and use a fan to move old air out of and new air into the room. Breathing that amount of dust can really leave you hurting. I’m speaking from too many experiences.
So what about an acrylic enamel paint and primer in one over oil based?
Anything that claims to be paint and primer in one is a LIE. It's like 2in1 shampoo and conditioner. Marketing at its best.
The only way to use water based paint (acrylic, latex, etc.) over oil based paint is to seal with a good quality oil based primer OR shellac primer.
oil based primer if oil based paint underneath cover in denatured alcohol, test the sections you will be painting. denaturalise alchlock will wipe off water based paint but not oil based paint
Hey was curious about coating oils with the same brand and color match but with a water base, I'm guessing my wrinkles are from too thick of 2nd or 3rd coat. I'm painting a 2'x2' sample before painting my finished product 6'x6' panels. My sample turned out perfect, attempted the same on my sign faces and got wrinkling on some edges and two larger areas one on each face.
You’re attempting to put water based on top of oil? And it’s wrinkling?
If that’s the case you can use a clear binding primer in between the oil and water based coat. Something like this: amzn.to/36QRahG
@@notwaitingtolive yes and it only did on my big panels, not my test panel. Thank you for the quick reply, maybe in the next ten years when I attempt this again I'll try that. But this current project is getting sanded down to primer, primed again then I'm just sticking to the water based.
I’m no pro but if looks glossy, my first thought will be to sanded it down. I however learned one thing from the video, apply a test chemical.
I did this recently in a bathroom. I wonder if a little heat and a scraper will get it to peel off?
Robwestcoast I haven’t used a heat gun in this application but I’ve read that a $20 gun like this that they sell at Home Depot will soften paint water based paint. amzn.to/2W86HVz
If you need to strip the walls you’ll be better off using an electric pole sander to remove what ever isn’t adhering well. For the trim, a wipe down with denatured alcohol and a light pass with 100-grit or so sand paper should get you to the point where you’re ready to cover up what’s needed with an oil based primer.
Be there forever!!
What to use now that you can’t buy denatured alcohol in California?
how do you know if your surface has oil based paint on it?
Nancy Clifton if you wipe the surface with denatured alcohol and the paint doesn’t wipe off its oil based (use a colored paper towel or rag to see the pain wiping off). Alternatively you can just use water, but it’s harder to tell. Water based paint will eventually be noticeably affected by water based paint, but some of the semi gloss paints take a little bit longer to break down. Water does not wipe off oil based paint.
Now, how did you clean it?
Sylvia K I use denatured alcohol to clean up fresh water based paints. I use paint thinner to clean up fresh oil based paints. I use acetone to clean up dried old paint of either type. And in general I simply dust before applying new paint/ primer. Many people will recommend cleaning the surface with TSP (a cleaning solution you can buy at stores like Home Depot) before painting. Another general recommendation is to use a wipe on liquid deglosser on semi gloss or gloss surfaces instead of a primer before painting. I will almost always just paint right over water based paints without cleaning or prime over oil based paints without cleaning.
OK, so what is next after the water based paint is removed?
OR same question really
What should have been done in the first place to the oil based Kilz?
Starting with an oil based primer or shellac based primer will enable you to follow up with whatever water based paint you want to use.
I am planning to paint our doors and trim that had been stained and lacquered. Started with kilz hide all primer which is a water-based primer and noticed once it dried you can scratch some of it off with a moderate to hard scratch. Will that cause a problem after other paint is over top of it and do I need to go back and use an oil based primer?
I'm a complete newbie on paint trying to learn first. How do I know if I have oil or water based paint on my walls... Do I use denatured alcohol...or is that only to remove paint after you make the mistake of painting over oil based
desertcat3 water works too for identifying oil based paint. Denatured is just more effective. Use a wet rag that has different color than the paint and try to wipe it off. If you can see the paint coming off it’s water based. If you’re only washing off dirt or grease but no paint that’s oil based paint.
@@notwaitingtolive I think you can do this test with acetone ( polish remover) as well. Just cheaper and most of us chicks have it on hand (acetone) I seen this tip in a Home Reno VisionDIY vid.Thank I did this mistake to our kitchen cabinets! Biggest pain in the rear ever.
can i paint acrylic paint over old epoxy floor
You need to sand the floor first with ~100 grit sand paper to give the paint the ability to adhere to the surface. You can use a pole sander or electric pole sander to make that task a lot easier than doing it by hand amzn.to/3hl64Ao. I'd recommend priming it as well with a bonding primer before painting.
Floors take a lot of abuse. I'd recommend using oil based paints on the floor as they'll be more resilient.
Hello! I have made the mistake of painting over oil based paint with water based (hybrid) paint that was suppose to stick to oil base. After several months of the paint job being completed i noticed a spot that had peeled up. Well…the paint on the entire door easily peels up. My question is..Can i paint over the other doors and trim that hasn’t peeled up with an oil based primer and then go back over with my water based paint?
Best to remove all the loose paint. Sand the old oil based paint down fully (not just a quick rub) and prime with a good quality primer. Water based is fine. Then undercoat and 1to 2 top coats depending on the paint. People think that because it's fast drying it's a quicker job. There's way more prep work involved than with a recoat of oil based paint.
I used a primer over the oil-based paint before I put on the latex paint and it's still peeling off the walls. Now I have to redo the whole kitchen
Was it an oil based primer as well?
Haha. I made the same mistake on a window! Lol
Live and learn. At least we’re wiser for it.
Iv literally just done exactly this 😭. Painted three doors and trims in my house with satin and realised its all peeling off. Do you need to sand before applying primer? Also does the primer have to be oil based?
Yes and probably Yes too.
When we have oil based trims we always sand and use an oil based undercoat ( I think is just more durable than water based primer)
Don't forget to wipe it out all dust with a damp clean rag before you apply the primer too.

How can I paint over a semigloss wall with flat paint without sanding? I painted this wall with semigloss by mistake yesterday.. 🤦🏻♂️ whats my options? Thanks in advance!
R G There are two steps to going from a semi gloss to a flat.
The cheapest route (but maybe not as effective) is to wash the wall with TSP (trisodium phosphate). This is a common cleaning solution they sell at Home Depot that is what most painters use for prep work. amzn.to/2PmiGdk
Alternatively you can use a more expensive liquid sand paper/deglosser which is designed for removing sheen. But this will cost serval times more than just using TSP. amzn.to/3a2OAp3
Then no matter what you use to clean the wall, prime over the wall with a dedicated primer (not a paint and primer combo) before painting. amzn.to/2ELNmmo
P.S. flat paint is very sensitive to scuffing and marks. A lot of builders use flat on the wall just to save money and hide imprecations because the lack of sheen makes defects harder to spot. I highly recommend using BEHR extra durable flat when painting flat on walls. I use this paint when painting garage walls which are usually full of defects and susceptible to scuffing. www.behr.com/consumer/products/interior-paint-and-primer/behr-ultra-interior/behr-ultra-scuff-defense
not waiting to live thank you very much for the info!! I guess no matter what I will have a lot of work! :( what happen if I just apply flat paint on top or the semi-gloss? Can it survive without touching it? Cause these walls i painted start at 6ft up to the ceiling. So no body are going to touch them. The question is if it would survive years even without touching it.
R G the semi gloss sheen will shine through the flat making it still appear glossy. The most important action you can take to knock down the sheen and give the flat paint the best chance at adhering well is to prime the wall with a dedicated primer.
not waiting to live ok thanks!
Can we use oil based primer with water base paint?? 2nd are there two types of wall putty? Wall putty for water base paint or wall putty for oil paint??
Yes you can use oil base primer and then water based paint.
There are a few types of wall putty and joint compounds. You will want to sand and prime over whatever wall putty you choose before painting. It won’t matter whether the putty is going over oil or water based paint.
@@notwaitingtolive means that i can use oil based primer then wall putty and than water based paint.. it will not affect my color right?
@@hanzallamuzaffar3288 you need to prime the wall putty too. Everything needs to be primed to paint evenly
Thank you for your time brother ❤️ last question is today my father told me that in your room there was oil paint and now you're planing for water based paint. Can i apply water based paint on it because oil paint was about 10 to 12 year old..
