Thank you for all your comments on that video, which led me to believe that when we held the 3/16"x1/4" v-notch trowel at a 45 degree angle, it applied too much of the membrane.
To make sure, I measured exactly the amount of REDGARD we needed to achieve the 80 sq.ft. per gallon rate that is recommended.
I found out that between a 15 and 20 degree angle on the trowel is needed to accomplish the correct rate of Redgard application.
Much flatter than the 45 degrees that is included on the instructions of the tub.
Anyways, I was really happy with the results, the first coat was dry in 7 hrs, and the second coat dried overnight.
The finished surface dried in 24 hrs: clean, sound, and at a thickness of about 22-24 mils.
Thank you again for all of your comments, it helps us all get better at what we do.

Finally we can have open discussions about shower systems, without someone saying, “my way is the only way!”
But.. It is!
I use Red Gaurd quite a bit and always brush and roll it on. Apply thinner coats and more of them .Thinner coats dry much quicker. Never had any problems with it .
amen! brush and roll
yep!
@@TheMVCoho same. I do 3 coats with brush and roller as as the fiberglass and this is all on top of my normal pan liner and floor mud
I think i'm going with brush and roll for my first ever tile job in bathroom. Pray for me brothers
Great video. It's good so see contractors who are willing to try things and admit that they don't know it all. This is greatly helpful to everyone. Nice job.
Hes not trying nothing. He still wants it to fail. You paint it on, its way too thick again with the trowel. This guys a jerk
Thanks for doing these tests. I’ve always brush and rolled it on, here in Mississippi we make mud pans with pan liners and then coat the showers with a rubber membrane. We rarely use schluter and after seeing your videos, I am glad we stay away from it. I just always felt that thin set is too porous to attatch schluter joints together with. But you are legit testing the industry and I applaud you for it. These companies need to take these into consideration and fix some heavy faulty issues
Can't believe people can say anything negative about your process, or you. You are the best.
your a really good guy love the way you show repect to everybody with all the hate and good comments bro your doing a great job and keep it up much love bro.
You said it perfectly. Great guy, great attitude.
Not a tile guy, but trying to learn and I find your videos, particular this one, really informative. Thanks for putting this out there.
I’m so glad I did not see this instructional before. I’ve been brushing on 3 medium to thick coats before tiling. Dries quick and no failures. I could not peel it off if I had to.
i did my shower 3 years ago . Used a roller for he walls and a brush for the corners. Applied two coats. No problems.
Hey Isaac, love these videos that you experiment with different tiling products! Thanks so much for doing it and sharing it! Awesome and God bless!
A++++ Thank you so much for taking the time to do all that, and bringing us along to learn with you. I enjoy watching your videos, they have a ton of info. You are very honest humble and transparent with all your work witch is very rare in todays world. Thank you and keep up the great work for the ones that appreciate you!
A lot of learning is learning how not to do it, just as much as doing it properly. I think it's great that you showed the failed video and showed a successful video. It allows us all to answer the question, "what if I apply this to thick, what will happen". You have probably saved a lot of people money who would be willing to apply the thickness of the application at their own discretion. Thanks for taking your time and resources to teach us. This experiment was spot on and the way I would have done it for testing, right down to the ounce.
Thanks for the video....been enjoying your content! While it's not "rocket science", I am glad to hear there are others out there who take pride in the trade!
Gotta test rolling it on. Troweling looks like a complete pain.
Good job Isaac, love your devotion to your trade your very helpful to us!keep doing what you do it works👍👍
Hey great job on the video. And it's good to see you handled the negative people with politeness and respect that's awesome. And to all you negative people out there lighten up a bit it's just a red guard experiment
I am doing my own shower and as a master carpenter who is experienced in the process of following steps your video was most helpful. with respect to applying the redgard. Thanks for taking the time.
Great video and your sincerity definitely comes thru. Nice job.
Thanks for all you are doing Isaac.
You are a humble man!!!!!!! I gained from watching this video, Now I am feeling more confident to use this product and get good results.
I am not professional; I am just a home owner like to do thing myself. I had very successful experience with REDGARD. I used just brush and roller and applied thin layer multiple times until I finish all the REDGARD I purchased (maybe more than I really needed). The result was great. My shower was done 5 years ago and no leak so far.
Thanks Isaac! I really appreciate you taking the time and then sharing the knowledge! You're a good man!
Putting any product to its limits and finding the failure threshold is a useful experiment.
Great video and I appreciate your humble honest approach to try and give people examples, perspective etc. Constructive criticism is very important and appropriate but above that it’s just dysfunctional people who unfortunately need to make themselves feel good by overly criticizing others. I recently checked out your videos specifically searching for shower sealing tips and appreciated the information provided. I just finished doing the sealing of my shower and I used the Schluter pan system that actually had the membrane. I finished the entire pan with their corners etc just to keep the pan consistent, then Redguard for the walls over Denshield backer. I made sure all surfaces were clean before starting and then rolled on 3 coats for the walls and brushed the corners well inserting fiberglass mesh into them. The thinner multiple layers for the walls worked really well for me with excellent adhesion. The thinner coats dried much faster and a circulating fan sped that up even more. I’m very satisfied with how well it adhered to the walls and I’m sure when applied right it would do the very same for the pan. Keep up the great videos as learning is just as valuable from failures as it is successes.
Good demonstration on Redguards recommended coverage
hey boss i allways apply 3-4 coats with brush and roller. been my best method so far. pretty consistent too.
Awesome. Thank you for doing this. It answers questions you cannot find elsewhere.
YOU HAVE DONE A GREAT DEMONSTRATION OF THE GOOD ,THE BAD AND THE UGLY OF PRODUCT INSTRUCTIONS,,,THANK YOU
Love it. Like your humility!!
Really like your humility dude. Keep it going
I am not in the trade, but if I was I would be super appreciative of the work and effort you put into this
I use red guard all the time but I roll it on also before I set tile I use kerdi ban in all my corners. Maybe over kill but never had a leak or grout cracking in the corners! Keep up the good work. Been tiling over 20 years and always want to be the best and willing to learn different technics.
So the Kerdi band over the red guard ?
I’m need to try and do things myself and I’ve super appreciated of these kinds of videos and such. You and a couple others have really got my knowledge well.
A video on how to level walls that r jacked up from old wood and old houses and stuff would be helpful as well. Think I make some stuff harder than it has to be. Thanks man and keep it up
Great video!! I appreciate all the hours you put into making videos for us!
Looks good, Nice job Isaac
Great job Isaac. Love the modesty.
Good comeback video bro .. keep it up
I was waiting for a StarrTile to follow up on his red guard video. You so quick👍🏼👍🏼
That guy is a pre slope short of a code built shower.
@@renaissancemen1 😂😂🤘🏽
Great follow-up video . I appreciate you taking the time to figure out what went wrong on the first go around. I have an irregular shaped shower pan area in a wet room and so I have to use Red Guard or similar or live with way too many cuts in the vinyl pan material. I'm nervous about using Red Guard and will likely put on a third coat just to be safe. It should get total thickness to close to the 40 mil PVC liner.
Thanks
Thanks for the video as always. Custom gives away depth gages for free. Makes everything go real fast. Apply, measure and keep going.
Love your professionalism
This guy touch bases on what to do and what not to do? Cause and effect pertaining mixs and other chemicals solutions. This is important for the DIY's guys
Nice man way better second time around! Am I the only one who was oddly satisfied watching this red guard spread around by the trial? Cool cool!
By the way, you do a great job on your videos. I set a lot of tile. Most people out there don't even come close to the quality of work I do. And you my friend are right up there with me. I stopped counting at a hundred thousand square foot of residential tile.
There are a few of us who do quality work.... ;)
quality is more important than quantity
Thank you for sharing. Extremely helpful.
This was super helpful - I learned so much - thank you so much
Mesmerizing to watch--I like how much can be done with the trowel. Precise
Yes much better. I still like to use my kerdi trowel first. Let that dry a few hours and then flat trowel to fill the ridges in. Keep up the great videos.
Hey Isaac, Andrew McNeill of McNeill L&R in Barrie, ON Canada. I enjoy your videos! As part of my renovation work I do a lot of tile and custom shower work. I have been using Redgard for at least 6 years, mostly as a pan linear over my drypack shower beds. I have found that a brush is the best way to cover the area and acheive the correct thickness. It usually only takes about 1-2 hours for the first coat to cure, often less. I will always do 2 coats and sometimes 3. My results have been excellent thus far. As you found out, you don't want to put it on too thick...that's the big thing. I have yet to use it on shower walls over drywall? I generally don't use drywall in showers at all, usually Kerdi board which doesn't need Redgard. Thanks again!
I use a roller like most. Would love to see a video of how many coats is needed to achieve their guild lines. I'm assuming that you still have more red guard. Do a small test just like this 5sqft of dry wall roll a coat tell covered let dry roll the next tell you've used up the needed red guard. it takes us 3-4 coats but we tend to round up to the next .5 gal. We don't hydrate we do a heavy coat 1st letting it soak in and by the time the first coat is done the first wall is dry and ready for coat 2. Time from 2 to coat 3 is 2-3hrs and we put a fan on low in the shower to keep air moving and work in a different part of the room. The other thing with the heavy first coat is it helps to cover screw heads the edges of the mud where we put seam tape on and any small holes in the dura-rock that the builders are using in the showers where I'm from.
Much better pal.glad ya sorted the first nightmare out 👍😂
Good video mate , I use red guard quite a lot I use hydroban more but I do use plenty of RG, I have been applying it with a heavy Matt roller and I do 3-4 coats and it ends up much like yours in thickness, personally I think it’s a great product I haven’t had any fails that I know of , hydroban will always be my favorite just because of the thickness it goes on and the rubbery finish , it just depends on the home owners budget.
Love your honesty
I like your 7 day kerdi tests, which, as you have pointed out, are about 6 days more then anyone would test a shower pan.
That being said, I would really like to see someone, anyone, do a 7 day test with kerdi membrane or kerdi board and seal the corners and changes of planes with red guard and Red Guard Fabric Membrane instead of Kerdi band and thinset. A combo of both systems!
I know it's not practical in the real world, but neither is a 7 day test.
But, I think there is a damn good chance it will pass that 7 day test!
So, what do you say?
Anyone else wanna see this?
Are you referring to the redguard membrane they sell at home Depot it's similar to kerdi band?
Just do it Issac. Please
I want to see it too.
Im trying to save $ on an addition 676sf on top of my rancher
Been a year from start date.
With just me, my veterinarian marineand 3 time cancer survivor father in law, and his brother in law - (a 70yo pastor whos wife just found out she has breast cancer) have done it all. I am truly blessed.
But cant chock down the price for a kerdi shower kit 42 x 60 is close to $500 . So im thinking hot knife slope cut some rigid foam panel and kerdi membrane that . Or try to use the Oatey pre slope with kerdi membrane. Will you try it and test it? It'll save me money both ways fail or pass.
@@nathanwebb4671 your an idiot
Lz
Isaac that is a dope jacket!!
love your videos....we are about to Red Guard our shower pan/curb...fingers crossed!
I've used red guard a couple times and don't know it ever failed (old house and a 3x3 foot space) so the last video of yours before I went ahead with it again was all about "over aplication", and really reassuring to see this one about "proper application" makes it a usable product.
I will note, the substrate is always going to be a factor (other video the deck mud hadn't solidified) and my current application checked Ina coupke spots and I had to scrape it off in a couple spots and re-apply the base (I think it was leveler dust (small half bath space I had mix and apply inside of)). But everything is looking good between floor and shower walls once the finish/decoupling-water barrier coats were applied.
I will agree, that for a one time user, instructions are kinda vague on how much to apply and how, but really that's kind of a tile wide industry problem like thinset coming in 50 lbs bags, and only needing 1/3 - 3/4 bag, either get a scale to weigh what your using or hope your opinion of peanut butter consistency is the same as the designer. Very observer/operator heavy on what us what and unless your in the spacific trade, it may or may not hold up being just a little off.
I've mixed a soupy thinset and made it work for me in the moment, and may show failures some day, and made stiff thinset that could also crumble some day, but so far... seems to have worked. 🤷♂️
Had me really nervous about my own redgard application :)
Thank you for the information.
Trowel recommendation is to use the flat side as a skim coat to key in the first application to the substrate then use a roller for 2 more applications letting the 2nd coat dry before applying the 3rd coat . I agree the coverage is a little less then what is needed especially if you use a duraroc board because of all the pinholes . But the pinholes actually give the redgard something to grab onto which makes me sleep easier at night .
We do commercial an we usually do three coats an we roll it on with a roller never with a trowel
love your vids thanks, i like the experiments
These monolithic membranes need a consistent thickness, and applying with a roller is usually the right thickness for this product and others such as Proseco.
Beautiful, beautiful job, showing exactly how it needs to be done.
It seems that Custom's literature tends to contradict itself quite a bit.
Some parts say hold the trowel at 45°. Some say 80sf/gallon, twice. Some even say to use 93 mils for a waterproof membrane. All three are conflicting.
Assuming the total 40sf/gallon is, in fact, the goal.. then this video helps a lot.
Keep up the good work
Great video!! Thank you!
I would like to see a roll on application thickness.
Great video's:) I personally like to use a short nap roller for my first Cote then switch to a long nap and I roll on as many cotes as needed to get a solid color like if I was panting a purple wall white. I like the texture long nap adds it feels like the mortar can really grab:)
Ignore the idiots. Your practical demonstrations are very helpful.
Yo Isaac, I'd like to thank you for trying to do independent tests in this industry, it's very important. As it's seemingly two sides, one who are legal eagles afraid of getting sued, and another basically who go "well my pappy did it this way so..." kind of stuff. It's like motor oil, diesel motor oils a lot of times are better motor oils than gasoline car motor oils, but oil manufacturers won't recommend them for gasoline cars for a lot of reasons, mainly legal environmental ones. But actual independent testing shows they're awesome. I know you'll probably never get a Robinson floor machine or something, but still, keep up these tests. I'd love to see Aquadefense, Hydroban, etc, tested troweled, brushed, rolled, make tiny swimming pools, whatever. The more reasonably scientific testing we have out the better, so thank you! :)
I've done two tile showers now with REDGUARD and no PVC liner. One is over a year old, the other is a few months old. I roll the floor with a 3/4" nap and a paint brush in the corners (with fiberglass mesh). I apply three thin layers to get the recommended thickness. I flood test them before tiling and they all hold water perfectly.
If I'm putting in a cement pan, I'll never use PVC again.
thanks for the product test
So much simpler to just use a paint roller in addition to a waterproof membrane in the corners, edges, and substrate transitions.
Paint rollers will not do 80 sq. ft per gallon in a uniformly thick layer. Yes you can use a thicker roller to get 20 to 60 sq ft but it is no longer uniform. Thick rollers are for rough textures like textured ceilings not smooth surfaces.
I wish Custom Bldg Products would address this discussion as to whether several light coats with a paint roller will achieve the same thing as two thick coats for minimal pan liner thickness. Otherwise we are all doing it wrong.
Thanks Isaac you rock!
Wish Custom would "invent" a roller that will meet their spec of 80 sq ft/ gal
I would guess that 90% of redgard is installed at incorrect thickness.. and I also agree it's something they definitely need to address..everybody sees two coats but they don't look any further into the thickness of the coats roll on two and call it good.
It makes sense to me, to work out SqM/SqFt area to waterproof; then measure the total amount of redguard for that area, and just roller it on in thinner coats till it's all used up. 2 thin coats will dry in the same time that one thicker coat will. Just use a fan or gentle heater to speed up the thin coats. On some jobs the 1st coat will be dry before you're ready to start applying the second. Yes, it's more rollering, but a big roller is pretty quick.
mils are 1/1000 of an inch. millimeters are 1/1000 of a meter. HUGE difference. You've pointed that out in other videos. Good call!
Seems like an adhesive roller, like for contact cement, would give the right amount of thickness (they are at lowes by the melamine/formica laminates)
Going less than a 45° angle, almost flat like u say, would push the paint onto substrate, similar to being rolled on. Nice display 👍
the Einstein of tile good dude
Great video.
Great video thanks 👍
Beginning of video:
"thanks for checking out one of my videos"
Yeahd dude I'll support your channel with a view and a like. I mean that's what we are here for right?
Some people are assholes on the internet. Work of art glad we all learned something!
i thank you did a great job....
This is it, now I have different opinion !!!👍🏻
You, landberg and star tile need to get together for a CZcams meet, the trifecta of CZcams tile pros. Starr gets a bad wrap man, he's atleast preaching waterproofing and showing home owners what to expect and what red flags to look for. I feel his channel is geared more towards that direction, maybe not what "the pros" are looking for in a tile channel. He's probably double my age so i have to believe he's survived this long because he's talented and does quality work
@@TileCoach these videos are great and can be used positively to share different ideas and techniques used all over. Some people are just assholes i suppose
Isaac Ostrom don’t be so cordial. That guy talks against preslopes. There is no room for that. He throws some scientific terms into the mix to make him sound legit and you have the makings of a clown cult of anti pre slopers. I’m a remodeler. I do pre slopes.
@@renaissancemen1 i have to believe you're some jealous jerkoff, atleast starr tile posts videos showing his work, some dickbag with no content going around criticizing people is whats wrong with youtube
Renaissance Man If the shower pan/mud bed is waterproofed with a roll on membrane or something like Kerdi then what does a preslope do?
@@krehbein if you do as your saying, you are creating a pre slope lol. The secondary now is the thinset tile is set with. Your in essence making a waterproofed, sloped surface your going to directly stick tile to
I agree with you guys. Always used a roller to apply all these types of water proofing and always put my fabric on with same material. I have been installing tile for 30+ years and never used any of this stuff. I also have been fortunate to renovate bathroom that I have done from 30 years ago and found no failure in any of my work. I always feel none of this new stuff cant hurt but if you are doing the right job from the begining you dont need any of it. All these waterproffing materails just make a bad tile job last longer. Learn how to do your job correctly if you are going to call yourself a professional .
Your the man
We got us a real movie star here!
Exactly!! Why spend more money when you don't have to? Red Guard is a GREAT application to WATERPROOF your shower job! Kerdi is an EXPENSIVE system that does the same thing and has the same chance of FAILING! Nothing lasts forever, The most you can hope for is 10-12 years with a good install. It's 2019, nobody will have a shower for more than 5-8 years. REMODEL, REMODEL REMODEL.
Thanks for the vid
Second time is the charm!
Ive found its best to.use a paint brush to apply Redgard and multiple thinner coats with thorough drying time between coats works best to prevent blistering and cracking.
3 coats on all seams and corners, 2 coats on walls and 6-9 coats on the floor and drain.
I end up with the floor about 1/16" thick with the fiberglass mesh tape or cloth and about half that without the mesh or about 30 mils.
OK best results I got is using actually a 1/2nap roller and roll it on with 3-4 coats on a shower pan and it's holding on my installs for now almost 20 years without a single issue. I use cheap nylon naps on 9" rollers and coat in thinner layers more often still I see the sold dark red is covering close to 80% of the see thru on the material. Write with a black marker on the sub surface. Once you can't really read it anymore you have a good thickness and apply it with a roller safes your butt big times.
I have spoken to reps from custom and was told two coats was a minimum to make sure there was full coverage that's why I ended up doing three coats and as I stated in the last video after 3 coats I generally average 30mil. I appreciate your work I enjoy watching others in the trades not to criticize like a lot of people but to continue learning and help when ever possible.
amazing difference, thinner coats and 70 degrees,,I think I'd use a roller, hows it compare to the hydroban,
Great job Mr.O... Different strokes for different floks🤙🏽💯
You should look into aqua seal which is lowes version of red guard. Also when I use aqua seal I roll it on with an roller and I do up to 4 to 5 rolled coats each coat takes about 1 to 2 hours to dry and when done with all coats makes an nice water proofing membrane where you will want it at. I have never been disappointed in aqua seal.
Hello, digyour videos. We are working on a bathroom and plan to use Hardibacker cement board and redguard. I see some people use quickset cement on the hardi baker joints with mesh tape but should we use the same material we are going to use to apply the tile? Redguard recommends using a polymer modified mortar for setting the tile, should we use this also with the mesh tape for the joints? Also, would you use a different cement board backer or water proofing membrane combination? Thanks again Tile Coach!!!
I really like your videos and humbleness. You try your best to get the most accurate info. Thats Title coach. I have a question, do you perfer aqua defense or red guard? Red guard is harder to find. Thanks
Thanks 👍👍
