I appreciate the time all of these workers take to show us these things. It slows them down a little and their time is valuable. Thanks for this and all of the other videos like these!
Glad to help!
This is by far the best video I’ve found on CZcams for self leveling a subfloor. Thank you very much.
Glad it was helpful!
Out of all the videos I’ve seen this was by far the best this guy is a pro great work
Hi, Thanks for your opinion!
Ahhhhh.. finally. Now THIS is how its done. Good ole' fashion experience. Great job!
Thanks!
You do good work! Thanks for sharing how you do these jobs.
Hi David, thanks for your comment!
A thousand thanks for being such a big help!!!
I will buy through you.
Happy to help!
Looks great! Good prep floor makes the job so much easier
Hi Juan, thanks for your comment!
They are doing it right. Great contractor.
Thanks a lot for your comment!
Thank you doing this video. Educated me even more about this process and tools for the job!
Very welcome!
Jose Mourinho has started his own construction company. You sound just like him. Thanks for this video.
I feel the same way😂😂
I think this guy is Russian :)
Exactly
WOW!!!! Just wow! You are amazing!
Thank you!
Thanks for making this video, it gave me some great ideas. The lazer level must save allot of work.
Yes, you’re right! Thanks for watching and commenting!
Impressive as always
Thanks a lot!
You make it look so easy
After 17 years, everybody can do it so easy. Thanks for watching and commenting!
⭐️ love the tripod 😎 thankyou for sharing your knowledge ⭐️ 👍
Thanks for watching!
Thanks for that 👍
Fantastic job too 👏👏👏
You are welcome!
Thank you for sharing. By far the best video showing a novice how to level an existing floor. Uncomplicated and to the point. Great tutorial. Should one put a bonding agent on the existing concrete?
Hi Faisal, If you have a look on the subfloor - it's a green color. I did the application of primer for better bonding. I never put leveling compound over an existing floor without primer. That's a rule!
Also, that's an amazing effort on your own 👌
Thanks!
Soooo awesome thanks for sharing
Thanks for watching!
I hired and fired two different contractors after paying 5k to level my floor. Neither of them could flatten my floor enough for wood flooring. After watching your videos I learned what they did wrong and I tried it myself. Floor came out perfect thank you so much for the help. Thanks to you my nightmare is over.
I am very satisfied with your comment because I am making my videos for helping people to make the right things in flooring projects.Thanks!
Your a bad ass! I love your work.
Thanks! Very emotional!
For this big project I used a special instruments - tripods. They are really help to make very nice leveling. I highly recommend. You can support my channel buying this tripods. Here is link on my website page - - Floor Screed Tripods - bit.ly/2uVCPfX
Excellent Video! 🤠
Thanks!
@@MrYoucandoityourself 😊
Good job !!!
Thanks
Oooh those tripods are a great idea!! I've only just done by first ever job on my kitchen floor, a couple of bags and this was my main worry, wondering if I have my heights ok. Luckily it's turned out ok.
Great!
Great work! I thank you for the information as we are in the beginning stages of a basement finish and will use this as reference to level our floors!
Good luck with your project!
Looks good
Thanks!
nice work
Thanks!
Nice....who said this can't be done alone...lol you got the juice buddy...only a few of us left
Thanks 👍
great tip
Thanks!
Really really good quality work. I am afraid to do so I will keep feather finishing low and sanding high.
You can do it!
Very nice video 👍
Thanks!
that is the most precise technique i have seen, these grade elevators specify the height needed... needs a patent !
Thanks for your opinion!
Good job sir
Thanks
It looks easy!
Yes, it is!
you are very good
Thanks!
U a hard working man done all this alone not a easy task to complete
Thanks for watching and commenting!
It’s so level there’s not even a fraction of light getting under that straight edge. Good job 👍
Hi Chris, have a look on it too - czcams.com/video/RvDhN9n680c/video.html
Thanks for your positive comment!
Nice!🫰🏼
Thanks!
you can always tell how well you are getting on by the reflection in the wet mix. Any warps from a light source means not flat.....this guy has a mirror on the floor 😀
Thanks for your comment!
It’s 50 bags in what looks like a 300sqft room. How could u not get a mirror image on a pour like that. Also, he set up a form to the entrance of the hall..that one room alone potentially cost the client 5000CAD$ in levelling. Phase 2 would be continuing the flood into the rest of the condo.. = more money.
Recently used a self levelling mix on a floor measuring approx 1.2m x 2m. I only bought one 25kg bag, and really had to stretch the mix out, maybe should have used at least another half bag. Cost of almost 30 euro per bag ! This floor must have cost a fortune !
Tony Mak so approx 4ft x 6ft..yeah 1 bag would have got you a very skinny layer. When you’re pouring in a small space..a good tip is to use a small cup to scoop out small amounts and just slowly try to cover the whole area
MrYoucandoityourself where can I get the tripods purchased
Beautiful job ! You the man Awesome
Thanks a lot!
After I seal my perimeter areas. I always measure out in 24in sections the width of my gauge rake spreader. I mark with a sharpie the measurements on the ends of each 24in section. Doing such gives me a better idea of how much I should pour in that area. Just another way to try to do the best job I can. If I could post a pic of my sections I would. Great video btw!!
Great tip!
You sound like you know what your doing. Do you know if the same technique would work on wood subfloor? I realize that I would have to seal vents etc....but is it done with same material? TIA
Ready to lay anything on that bad boy 👍🏼👏🏼👏🏼
Thanks for watching and commenting!
MrYoucandoityourself let me ask you this tho..would hardwood glue stick really good and how easy is it to stain if you can stain at all? Thank you in advance
liking finger before touching silicone... nice trick
Yes, you are right!
Wow nice work. Can you explain more about the tool you use with the blades when you are wading in the mixture as well as the tripods?
Hi Nick, This pull-push tool call - Floor Squeegee - amzn.to/2JRRi6w
This tool not for leveling, but I use it all the time because ease to spread self-leveling compound.
About tripods - it's my favorite tools, I can do leveling with tripods from 1/8" to 1'1/4".
easy setup and work. Here is a link - - Floor Screed Tripods - bit.ly/2uVCPfX
Thanks for your warm comment!
Very informative video. Just wish I had the confidence to do the 70 square metre area 🥴🥴. Thanks very much👍
You can do it!
Thank you for the video. I found this is the best video for floor leveling. I have a question. I have started leveling using a water method to determine unevenness in one of rooms and I have placed leveling cement over a clean cement floor without first using a bonding primer. This application is for a residential job with a minimal unevenness. Can I leave it as it is, or do I have to remove it now and repeat again first using a primer? The bonding cement seems to be firmly placed . I plan to use a vinyl plank flooring product over it.
My dear friend, in this time you can just remove concrete, but after , when floor will be done and you get a problem with subfloor, you have to remove the floor, remove concrete, level it and then install new floor. I guess you can understand different?
But everything in your hands, you can leave it as it is. Thanks!
UZIN products are the best!
It’s up to you.
Thanks for all the videos! Big help.
What if you have a low spot at the doorway to the room… do you end up with a ridge at the edge leading into the next room? Wouldn’t you then have to raise the level of that entire room to match?
Lastly, do you mix your compound with more water than it calls for to allow more workable time?
Hi, you can match the level both rooms, or make different level and put transition in the doorway. Yes I add little more water then recommend on the bags. Thanks
Awesome video. My home is from the 70’ and the builder made a slope of about 1 feet in 25 feet of linear basement. The whole surface is about 500 ft2.
Do you know how thick I can go with self leveling concrete?
Hi, depending, what’s brand you going to use. For Mapei 3/4” in one time they recommend. Reed instructions on the bags. Thanks!
This is so cool! How big of an area can you do at once as one person? Meaning how long before it dries?
If the house is too big and you want to do the whole house, you can break it up into individual rooms, as long as the level meets correctly at the doors yeah?
Thanks!
Hi Gunter, all dependable from the many factors as year season, material, air humidity, water temperature. If you have at least 3 guys - you can do it in one shot, but if you are alone - do it by the room. Divide room in the doorway. Thanks.
This is Mapei underlayment...What do you recommend that is supposed to be used as a selflevel finished concrete floor? This is what I want me floors to be as a finished floor. A nice smooth natural concrete finish. EXCELLENT videos!!!
Ardex specially made for epoxy and polishing concrete surfaces. I would recommend this brand. Thanks
Thanks for the great tutorial. I guess you can use cheap concrete or stucco first is the out of level is too much, and then at the end use this more expensive self leveling?
No, it's not working.
谢谢
Thanks!
One big remodel I'm doing right now, house on slab, 1500sf was self levels in one pour.... He used something called uzin ... He said it was the best stuff you can get but very expensive. What brand do you like using the most? Your experience and skills are amazing to watch bro.
Hi Danny, you have a big project! I am using Mapei products. Self leveling compound not cheap and labor costly as well. I never use this Uzin, but now so many brands, if it’s work well - good for you! Thanks for asking questions and commenting my channel! Good luck with your project!
I wish I could find someone local who was as good.
Some guys do very well, but they don't advertise by themselves, because very busy. I am not advertising too, because working with the same builders and contractors for a long time.
I think I'm about to do a 750 sqft basement myself using mapei self leveling compound.
Should be a good time.
Do it in the morning with cool water. Good luck!
Great job , can I do that on painted floor ?
You have to remove paint.
Incredible result. Amazing level and uniform color. I usually get swirls of colors which are unsightly. What is that tool you are using at the end (like a roller with spikes)?
This is spike roller for leveling.
It was very nice working progress and excellent result !! I just have question for you please I am after levelling rough large area do you thing in some places if I need to go over 30mm I will be ok ? because the bags of the cement said max 30mm thickness ? Thanks in advance for your help.
If it’s not all place, just some spot I did over a 30 mm easily, like in this place from left side.
I've done it sometimes on my job sites, and it's always really difficult to achieve a good result. Especially if the slope is not "constant" and you have "bumps" (I hope you know what I mean)!
I guess it would be almost impossible to achieve a good result without tripods. Great video, thanks for sharing your skills!
Hi Francesco, You are right! Without tripods it's difficult to make.I have tripods, if you need it - - Floor Screed Tripods - bit.ly/2uVCPfX
Instead of buying these tripods. Just cut wood shims to the “height” u need to add and glue them to the concrete in the designated spots throughout the room. I guarantee this guy has kicked over his “tripod” atleast once while pouring.
kobi chicken that actually sounds easier. Do you just leave it in the concrete? What happens if you overflow it accidentally and lose them or does that not really happen in practice?
TwoLeggedTriceratops Its your choice. you can leave them in, or pop them out with a hammer and chisel. If u pop them out, just be prepared to mix a small bucket of feathering patch to fill the void. The shims don’t necessarily get covered unless u over pour. If ur worried about losing the shim..u could always tap a short nail in to each so u know where they are before u pour.
@@zaxazva hi well if you were going to do that then you might as well just put screws and plugs directly into the concrete and screw them to the desired height to give you your guide. Wouldn't be as noticeable either as timber. I think iv just invented something lol
I noticed that your compound stayed wet for a lomg time. How much water did you add to the 3 bags? thanks for the videos.
Hi Richard, one bucket of water for 3 bags of compound. It's not so long ass you think. If water very cold - getting dry slower. But, sometimes it start settle in 20-25 min.
You appear to show that this "COULD" be a one man job. I've seen almost everywhere else that for the bigger jobs (which yours is), you need two men to do a large floor. My floor is approximately 900 sq ft. I wondered if "dry" edges could be next to the next pour, would I need to sand where the two edges meet to blend in. Otherwise BRAVO!
Hi, this floor was 1200 s.f. I did by the parts. First of all I levelled dining area and living room (on this video). I bloked hallway with bedrooms and did it on the next day. Kitchen I didn’t touch because it was tile guys job. With tripods it’s easy to connect few rooms if you leveling it part by part. Thanks!
Can I do this to a triple wide mobile home that has old tile that is also uneven? The purpose would be to put down vinyl plank floor
Hi, if your subfloor solid don’t have any movement, yes you can do it.Don’t forget use primer. It’s very important! Thanks
Are you mixing the ratio of water to each bag as recommended or a bit thinner? When I’ve used this stuff and mixed it according to bag instructions it comes out more like pancake batter. Yours looks a lot more fluid
Sometimes I put more.
I added 200 square feet to my garage when i did whole house remodel/rebuild. The cement guy started at the slant of the existing 400 sq ft garage and added on the additional 200 sq ft. The issue I having is when we get heavy rains here in Texas, water comes in under my garage door. I have been wanting to add some concrete to level out the garage to get rid of the slant and raise the newer part of the garage floor. I believe i would need to add 1.5 - 2 inches of concrete/leveler to fix the issue I am having. Any advice would help. Thanks in advance. Very nice work!
With garage I don’t have experience. Sorry.
Beautiful job, what was used to fill the cracks in the actual floor it looks like it was smoothed out like plaster
We used mortar.
What is the name of that big metal you used in the final of the video? Great video
Hi, this is straight edge. You can find link in description. Thanks!
Why do you make it look so effortless 😭
Otherwise, you will stop watching it.
Awesome video ! how did you find the highest spot to put your laser ?.
How do I find the high spot on my floor? Floor leveling MrYoucandoityourself
czcams.com/video/pij008FP6AE/video.html
where did you get those adjustable pins to help point out level.?? Great job!!
I made it and sell it - - Floor Screed Tripods - bit.ly/2uVCPfX
If you order 12 tripods, you can get a spike roller and spike shoes for free. I will ship it the same or the next business day.
Great video. Thanks for sharing.
Did you mix the mapping novoan with sand??
In the video you add water, then you put the white bag mapei and after that you add one clear bag and back to a white bag again. Im assuming that the clear bag is sand??
Thank you
Hi Moses, I am not doing this, sorry. Only self leveling compound.
Was a concrete bonding agent/primer used before the self-leveling? Was it also Mapai brand?
Hi Goblin, in this video I said: primer applied already, you can see green colored subfloor. I used primer L from Mapei as well. Thanks!
What brand did you use for the self leveling concrete?
Hi Jose, my favorite brand is "Mapei". I am using Mapei Novoplan 2 Plus. Thanks!
What is that long metal metal square called? The one you drag accross the floor. Thank you Sir.
Straight edge, you can find link in description. Thanks!
how powerful must your drill be to accomplish such a task. Mine went up in smoke
Maybe already old tools?
Mryoucandoityourself how do you calculate how many bags you need, as the floor was uneven? And are you only putting down as much to bring the floor up to the original highest point?
Hi Paul, measure area need to fill up, for example, 200 s.f. sloping down from 0 to 1". One bag cover approximately 20 s.f - 1/4". Divide in half because it sloping - it will be 1/2" for 200 sf.=10(1/4") + 10(1/4") bags.
How long did it take you to do the 500 soft. Did you work it yourself, thanks ken
Hi Ken,this place I finished for 3 hours, including preparation. Yes, I work by myself.
What self leveler compound did you use and can you finish this type of self-leveler?
Hi I used Mapei Novoplan 2 Plus. I don't know about finishing this material, you can come to Mapei.com site and ask them. Maybe Ardex better fit for finishing. Thanks!
Do you calculate how many bags do you need or are you just eyeing it based on your experience?
Hi, it based on my experience. One bag cover 16 sf with 1/4".
What are the tripod gauges you placed on the floor to help gauge how much to put in that area? I will need them
You can find link in description for this video. I ship it same day.Thanks!
What is the roller called that you are using to go back through the wet patch?
Hi, this is spike roller for leveling. I sell it with tripods. Link in description for this video. Thanks!
Where do you purchase the foam for around the wall?
Hi Dale, you can buy it in any lumber store, just ask "Foam gasket tape 5 inches",
or you can buy on Amazone, link in the description. Thanks!
What is that plastic like material you rolled against the walls to create a barrier?
Hi Rodney. There is foam tape. I have link in description. Also you can find this material in lumber store. Thanks.
If you have a concrete pad that has slight unevenness, do you need self leveler, or will the mastic under the tile provide enough material to straighten out the tiles? My floor has slightly under 1/4" differences here and there but nothing drastic.
Hi Addie, some guys don’t care about level, just they putting more mortar under the tiles. I would prefer to make level.
Use some tile leveling clips to keep all the tiles on the same plane and avoid issues during installation caused by an unleveled floor.
Excellent ! Can you tell us how much you charged ? For materials and labor ? Thanks for your time have a blessed day Brother ! 👏🏽
Hi Walter, where do you live?
Albuquerque New Mexico USA
Ok, in Vancouver average price $80 per bag - includes material and labour.
What is the flow time for the SLU product you’re using? That’s not rapid set is it ?
Hi Frank, it’s settled in 30-40 min. For big area need to work very fast. Thanks!
whats the rolling brush called ?
Monish Lillaney spike roller, you can find link in description. Thanks!
So my first poor has some REALLY ugly spots. Im going to have to grind a lot of it down. and also fill in some low spots. What product would be good for filling in spots? Use the same SLC? Im using Mapei Self Leveler Plus+.
I don’t know what’s spot you are going fill up, but for leveling I am using one type of material. I hope to start getting salary from you because you keep me busy whole day. What the rates you have for helpers?😀
Hello! looks like 350 sqft. How many bags did you use? Thanks
Hi Joseph, in this video I explain everything. Just watch it one more time please.
I have an old wood subfloor that is very crooked. I want to install carpet, is it better to use self leveling compound first and then cover with underlayment? Or underlayment first and then selfleveling?
Hi, leveling first and then underlay with carpet. Thanks!
@@MrYoucandoityourself the old wood floor is made from many boards, not plywood. How do you keep the self leveling compound from possibly running through a crack, it is crazy to try and caulk between every boards?
@@EitriBrokkr You have to put over this wood boards minimum 1/2" plywood , screw it in, and then level it.
Did you have to treat concrete subfloor with anything for the leveling compound to bind to? You mad this look easy. In Florida on hot days this sets up too quickly to work it that long.
Hi Christopher, your have to start work very early with coolest water you can get.
Hello, what do you do with the foam covering the perimeter after?
Hi, Just cut off even with subfloor.
What is brand of foam around edges you use i believe u said 5$ in 1 video and where can u purchase (home depot, harbor freight, exc.)?
Which self level product did you use.
Also it looked really wet did you use the recommended water or did you add more.
Hi, I am using Mapei self-leveling compound. For 3 bags of SLC, I added one bucket of 5 gallons of water. Thanks!
Would this same process work for my 8x12 shed that I'm transferring into a tiny home? It has an 1.5 inch slant to the concrete slab its on.
Yes, same process.
Around 12 bags.
Great work!!
I like to use the same material how much water do you use to make it that liquidy?? Thank you!
5 Ga buсket of water for 3 bags SLC.
@@MrYoucandoityourself thank you
Do you have any experience adding aggregates to self levelling compound? I need to pour quite thick on top floor apartment and thinking about using a lightweight aggregate in the mix: love to hear any tips you have for this.
Hi, yes, I tried it before. Only headache… Now, if I need put too much slc, I am using backer board. Have a look my last video, please. Thanks
@@MrYoucandoityourself thank you for your reply. I watched the video and have three more questions: - it looks like you used extra mortar to bridge between different levels of backer board, is that right? Do you leave a gap between the pieces of backer board? Do you tape the seams of the pieces of backer board? I ask all these questions because I might need to use a variety of thicknesses of backer board, since the room curves down from the middle to the edges. Your videos are great and the views of Vancouver are super nice too! Many thanks from Australia.
I need to level the floor in a room about that size that is around 2" (5cm) low in some areas. Is this method the best for this much slope? Thank you for your videos.
I just finished same sloop.only tripods can help to set up level. Thanks!
@@MrYoucandoityourself Thank you so much for answering my question so quickly, and for the additional advice!
Happy to help!
Jesus Christ! This mobster is a floor leveling boss!!!!!!!!!!!!!!!!!!!!!!!
Hi Fred, thanks for so emotional comment!
nice job 👌. I would like to buy the Screed Leveling Tripods, but they are very expensive. My floor is the same way than yours 1/2, 3/4 and even 1 inch in some spots. Is there any solution to level the floor in those low spot without using 50 bags of self leveling because in the us 50 bags x 30 dollars= 1500 dollars just in self leveling cement please any advise. Also what is the water ratio for mixing. Thank you very much for your help
Hi, you not realize how much expensive it should be. This 50 bags would cost you with labour within 35 - 40 hundred.
Therefore, $300 for 12 tripods- its nosing. Also you need spiked roller, buckets, mixer and so on....look in description for this video.
Don’t forget seal the walls to avoid leaks.
Any questions, you can ask me here or on Facebook page.
Thanks
MrYoucandoityourself do you think I can lay some 1/2 Cement Backer Board on the low spot and then put some self leveling on the top ?
