Hi Don, lath will be effective, if subfloor has some movement, but this subfloor pretty solid and Mapei with T primer very good bonded with wood subfloor. Make sure wit lath you have to build up you floor approximately 1/2'' extra and cost more for sure.
I have a few questions 1- how do i know if a floor needs self levelling before installation? Do i run a 6 foot straight edge and wherever there is uneven part i put self level? 2- how do i know the mixture, like how much water and how much powder i should put for the self level mixture to be good. 3- what is that roller ur doing? What is it called and is it necessary ?
Hi, very good questions! 1. How do I know -Take a straight edge and check subfloor. Minimum straight edge lengths should be 8' and more. 2. All instructions you will find on the bag with a self-leveling compound. 3. In this video description, you can find all links for the necessary tools. Thanks!
Thanks for the video! My floor happens to be lower near the door opening which goes in to a carpet. How do I stop the cement from flowing out of the door? Also, do you razor off excess sill seal foam after the cement dries? Thanks a lot!!
Thank you for your great, informative videos! I have an old plywood subfloor that is slightly warped in some spots. Since it is old, should I reinforce the existing subfloor with 1/2" thick sheets of plywood before pouring the self-leveling concrete? Would the self-leveling concrete be too heavy for the existing subfloor? The goal is to install luxury vinyl planks once the subfloor is level.
Hi Justin, I f your subfloor has some movement, the best way make smooth grainding, then screw down all subfloor and then put extra plywood opposite detection with construction glue and screws. I hope, it’s will help. Thanks
@@MrYoucandoityourself I do have a big open area on the lower floor so I will use your suggestion to grind the subfloor and put new plywood on. Thank you very much!
Preparing uneven subfloor for tile by adding another layer of plywood and then Detra but the floor is not level should i first use self leveler and then the plywood or installing the second layer of ply wood and then self leveler before installing Ditra and tile ?
@@MrYoucandoityourself The tongue and groove floor boards are 18mm thick. I then plan to glue and screw sheets of ply over the top of the floor. How thick does the ply need to be for self levelling compound? Thank you
Main criteria for leveling wood subfloor - regular plywood 5/8” and solid settle , with out movement. I f you have some movement, screw the subfloor. Thanks
Love your work. When leveling around kitchen cabinets, what thickness would cause a problem removing or installing a new dishwasher? Since the floor is now higher than what the dishwasher is sitting on. Thank you.
Hi, good question. I would say 34’1/2” and thickness of the new floor. But some kitchen cabinets with different heights. Choose cabinets first and play from it. Thanks
MrYoucandoityourself I have an old house and I want to self level a large room on the second floor. I was told it will crack because it’s not the main floor
Hi Thomas, if you can install cement board- do it, depend how solid your wood subfloor. If your wood subfloor don’t have any movement, good enough self leveling compound. Primer should be for wood. And last one - don’t forget put anti fracture membrane. It’s very important!!! Thanks
I'm laying down luxury vinyl planks on my floor. After I level a subfloor with self-leveling concrete, would I need to lay down a layer of 1/4 underlayment over it or could I put the vinyl flooring directly over the cement?
Hi Elaine. Thanks for watching and your question. Every floor materials are different. You should follow the instructions on the boxes from manufacturer. Good luck with your project!
Is it okay to use this product on subfloor without lath? I’ve noticed that you haven’t used it in a few videos. Have you had any problems? I recently did a job using this product and am nervous because I didn’t use metal lath.
I never use metal lath. If flor is moving up and down, you didn’t have any lath, if it’s pretty stable, primer very good bonding leveling compound with wood subfloor. Mapei leveling compound good enough flexible. I don’t now about other material. Later on you will see some minor cracks, but it’s not a problem.
Good video, seems more expensive than I'd hoped. I've got a pretty big shed, about the size you did here, with all kinds of horribly warped plywood on the bottom. Thought of just filling it in with cement and letting it fill the holes, etc. Do you think one of these leveler 'kits' would be enough for this or does this really only cover small variations? Can this be done on the cheap or do you need some pricey tools.
Sand/grind down your high spots and then you can fill low spots with plywood... 1/4” or 3/8” depending on what you need or you can fill with a cement patch. But at approx $50 a bag for leveler, plywood is the way to go.
Hi: What was the material you installed around the perimeter? I'm assuming you put that on to create a sort of dam to keep the leveler from running into the edges, right?
Hi, what type of sander are you using? It seems that the sanding you did on the subfloor was not completely thorough, I can see some undone patches. I will install engineered hardwood flooring and need to use the same product you are using for leveling, but before that I need to remove/sand off the plywood subfloor. This subfloor has a small dried layer of glue that was previously used to install vinyl floors. Can I do a simple sanding as you did on this video? Also, my floor has a minor inclination/slope, though it is an even slant. The self-leveling I will do will be on some spots only. Since I live in an apartment, I am afraid that if I prepare the underlayment to thin it may run through the cracks and mess up my neighbor’s apartment below. Can the underlayment be prepared a bit thick? Thanks.
Hi Jose, for any apartment buildings need permition for floor installation. you have to know: 1.what tipe of floor you can install 2 what tipe of installation (glue down, nail down or floationg) 3. what tipe of underlaiment you can use. You can do any amount of leveling, only use right primer. Thanks.
There is a 16"x16" corner of plywood with a slight squeak and flex due to a leaking washer. I've decided to replace just that small section, and add a couple cross members between joists, since I have easy access below. I also have some redguard I can apply to seal it together. I failed to put caulk between the seams of plywood, so that may be a contributing factor. Thanks!
Hey tx for the advise. My method will be glue down. would it be possible to do this method on vinyl solid tile? Some are loose, can I nail those tiles down?
Do you have any suggestions for a transition between two sections of a modular home? I was planning to install nailed 3 1/4 X 3/4 gunstock over Bella premium underlayment. When I pulled the carpet and padding I realized I have a 3/4 inch gap between the sections where they joined and a straight edge rocks over the edges of the intersection. If I try to level it there would be house-wide consequences since it had been in place for approximately 15 years and I just finished spackling and painting the entire house interior. It has been suggested that I fill the gap with a leveling compound that applies with a goop consistency but I am unfamiliar with the product. Any suggestion would be appreciated.
I had a project like yours. I installed a floating floor perpendicular to another section of a modular home. If you want to install your floor nail-down, you should first to install a plywood subfloor across the house and than to install the floor.
Is all this necessary for laminate flooring?? For hardwood maybe but for floating laminate?? Other videos do not show putting down liquid leveling compound only sanding and filling in cracks, sinking nails and putting down the moisture barrier. My understanding is that the self leveling compound is for hardwood.
+truthseeker42 42 . It depends on the quality of your leveling under a carpet. Sometimes you need put liquid self-leveling (if your subfloor has low spots) and sometimes you have to delete the bumps to get an even level. And the most important thing: laminate floor should have very good leveling (even better then for hardwood floor).
LFergsuon you need to make sure your floor is within manufacturers tolerances, mine was off so I have to level it. I am using floor leveler, I could have removed the subfloor and shimmed, or sistered up against the existing joists.
The manufacturer requires metal or plastic lath over plywood subfloor to reduce flex. They actually recommend one coat of leveler, then lath, then a top coat. This makes no sense to me, how do you attach the lath?
Hi John, before answer you, I made research about how to use lath for wood subfloor with Mapei self leveling compound. No any info. Were did you find it? Thanks
MrYoucandoityourself it was in a UA-cam video from the manufacturer themselves. It is also on the bag I bought at Lowe’s, it’s Mapai Self Leveler Plus. It seems different products have different requirements. Though two coats of leveler sandwiching lath makes no sense. How would you secure the lath?
If subfloor doesn’t moves, I used primer T, and no problem. I f some little crack for hardwood or laminate flooring not affected but for tile you can install anti fracture membrane. That’s what I did always. Thanks
This was helpful. Thank you. I wish you had not played music during the presentation. I am sure you may have had some tips you could have passed along during the time you were working.
For each self-leveling compound there is special primer. For this project I used Mapei T-primer (for wood subfloor) and self-leveling Mapei Novoplan 2 Plus.
Question for any experts: Can you do a similar application as this with a concrete topping mix? We are thinking we would love a concrete epoxy finish (or look) to our floor...but we have a wood subfloor (only seen the epoxy finish on concrete slab floors).... Would a method similar to this work? Then after it hardens put on the epoxy topping? Or do we need to go thick with the concrete? (how thick 1") ? Reinforce the concrete with Lath or wire? Or what would be a good procedure to achieve this idea? Thanks.
I don't mean actual "concrete" but some type of similar product (gypcrete or a levelling compound,etc)...basically, can an epoxy coating finish be applied to this type of product? Or does it need to be a certain thickness?
I’d love to know how your project turned out. We want to lay self leveling concrete and then seal it in a few rooms of our house and would love to not have to pay for metal lath, but want it to last.
@@MrYoucandoityourself the music distracts from it, but whatever, can’t change it now (I don’t think?) Between the time lapse video and the music I’m expecting a tiny car to come flying in from one corner of the screen, slide to a screeching halt, and a bunch of clowns start climbing out and stomping through your work 😂

Thanks for these helpful videos. Some of the only videos out there for what I need. Why no metal lath after priming, but before the leveling compound? I was reading the specs of one of Mapei's self-leveling compounds and it calls for lath prior to spreading the compound to prevent overflex and breakage of the concrete.
This is not needed. A good underlayment will level for laminate. This is only needed in rare cases where the subfloor has variances in level across the room, hills and valleys. Don't let someone talk you into this.
+MrYoucandoityourself I'm not saying what you did in this video is never necessary. But you mentioned in a reply to an earlier comment that 99% of the time it is. Id say less than 10%. Floors with less than 1/8 inch variation in 6 feet don't need anything like this.
+MrYoucandoityourself I'll take that back, kind of. This is more important for glue down flooring, not so much for floating. I just didn't want the average joe doing a diy floating floor to get confused. I'm not hating on your video or work. I enjoy watching your videos. You make them better than I ever would:)
3/16” up to 10’ for floating floors. A lot of contractors do not correct low/high spots and there are issues down the road. I’d agree closer to 99% of plywood substrates need leveling either a sander/planer or some patching/leveling compound. But the floor does not have to be level...just flat so looks like overkill. Underlayment is definitely not a leveler btw...lol
This seems nuts. Why would anyone want to put hardwood flooring over cement when they could put it on plywood. Just mark out your lows and use roofing paper for a few extra mm. More than that then patches of 3mm plywood works fine. Unless your floor is floating. If floating then using self levelling is very good. I suppose the click type floating floors are best for this. They dont explain in this video WHY YOU WOULD USE THIS method and with what type of hardwood flooring.
Hi Adam,this preparation I made for glue down or floating floor installation. I don't recommend you to do it, because it's not cheap. Some people think - for laminate floor don't need to do leveling. This is big mistake. Laminate flooring locks with out leveling got damaging very fast. It's real wasting money.
I put down Henry leveling on a wood subfloor and didn’t use primer ( hate to admit I was told by menards I didn’t need it) looks great until I walked on it. I will be redoing the 13x12 floor again with primer
Thanks! This helped me a lot on how to use self leveler. Pretty important for tiling.
Thank you for this video. And thanks for all the information provided in the comments. Very helpful

They dont explain in this video WHY YOU WOULD USE THIS method and with what type of hardwood flooring.
Hi Adam,this preparation I made for glue down or floating floor installation. I don't recommend you to do it, because it's not cheap. Some people think - for laminate floor don't need to do leveling. This is big mistake. Laminate flooring locks with out leveling got damaging very fast. It's real wasting money.
I put down Henry leveling on a wood subfloor and didn’t use primer ( hate to admit I was told by menards I didn’t need it) looks great until I walked on it. I will be redoing the 13x12 floor again with primer
@@saltecservice what's the primer step for ? What does it assure you it does ?
@@aztecempire4206 The primer helps the self-leveling concrete bond with the subfloor. Without the primer, the concrete can develop cracks.
good god, that music was horrible!
sorry i sing even worse.
What product do you recommend for sections on plywood, I do not want to self level the entire thing, so I would need to go to a feather edge
