How to use floor leveler on wood subfloor to fill low spots before laying new flooring

[@Housebarons]

We can not stress enough the VALUE of having a laser level when doing this kind of work (or even checking the condition of the floors )! If you are interested, check out the link : DEWALT Line Laser, Self-Leveling, Red, 3-Beam (DW089K) by Dewalt amzn.to/3xNbY3K It works well but this is NOT the most affordable version. We actually have 3 different brands and they ALL work great. If you are looking for more affordable options, check out the video description or our other floor leveling videos in the following playlist : kzbin.info/aero/PLExVGissIl-H-npOe7v64K2y6IIOQvHk6 Just FYI.

I have been searching for an "every man's" version of this process for my porcelain tile project and your video is a HUGE help! Thank you for your time and assistance!

[@ptravers9077]

I have seen home that use this and the structure wasnt secure. In just years of settling it can crack especially if there is tile on top of it.. tile will not flex like the self leveler. It's always good to try and fix the problem from down below by suring up the structure maybe sistering up some wood and adding a beam or two.. what all work did you do before to prepare the structure itself?

[@Housebarons]

Hey P, Agreed. We did support that floor from underneath with double joist and floor jacks. Thx for watching !

Surely a screed will just break down over time on a wood floor due to so much movement? in the U.K we just wouldn't do it

All depends on how much give or deflection you have in your floor joists. In this house , we added significant supports in the basement = zero deflection. But something to consider. Thx for watching from the UK - cheers!

I was wondering if there was any structure under the floor, and if so, would fixing the underneath structure make the floor leveled?

[@Housebarons]

Hey Mings…, Always best to start at the structure. We were able to jack up the floor and resupported some, but due to the age of the house and how long it had been sagging, we had to do the finish work with the floor leveler. You are on the right track! Thx for watching!

Can you install 3/4" refinished hardwood over this layment? Will the staples penetrate the Henry layment?

[@stricklandgarageaviation2864]

After reading several of the comments, I understand that nails or screws will not penetrate the layment. So the area where the layment is used I'd have to glue the oak floor to the layment. I hope I can find a glue that will adhere to the wood and layment. Any ideas?

[@Housebarons]

Hey @stricklandgarageaviation2864 , We actually have that same project coming up. There are glues that will adhere to concrete which is what the floor leveler is. The caution is moisture. If you are on a slab, you have to make sure you do a moisture test (cover a 2 foot x 2 foot square with plastic and tape down the edges. Wait 24 hrs. peal up the plastic. If the concrete under the plastic is wet the next day, you have a moisture issue. ) One idea we might consider ( that I found online ) is liquid nails. It will also bond with concrete. Hope that helps. thx for watching

Hey Mmy…, We did use this product and feathered the edge and found that it did not crack or crumble at the feathered edge. They don’t advertise it as something that can go that thin… but. we found that it worked fine. I believe Henry makes a different product that is advertised to go to a feathered edge, but I don’t have the number. Your local big box store may be able to find another product they will do the same thing. Thx for watching!

I can put my plywood down and then do the level out in the center of the floor. Or just a little bit on the plywood. I watch the rest of the video, but this is the solution I was looking for. It seems simple, but I didn’t think of it without your help. Thanks!

Hi I'm hoping you could help me🙏!!!! we painted the OSB subfloor with latex Zinsser odor blocker. Will the primer ahear to a painted floor or can I cover the floor with Luna. Will the primer and selfleving mix ahear to Luna. Thank you so much for any and all suggestions 👍

[@Housebarons]

Hey Sharon, I’m a little confused as to what the layers are. The leveler we used said it would stick to osb. The leveler bag should indicate what it will stick to. When in doubt, I would call them to be sure. As for zinzer - same thing - Some of those primers say “ will adhere to painted surface without sanding. Regular primer typically will not stick. As for the Luna flooring, if it is flooring you are covering, I would rather pull it up. If it is your final floor, it should lay over everything if it is a floating floor. Hope that helps, Thx for watching.

[@sharonk526]

Hi Dave, thank you for your responding. Basically we tore up the old carpet to the OSB subfloor. We are going to be installing the LifeProof Vinal Plank Flooring. However the floor is so unlevel we need to mix a batch Of the floor leveling compound. But before I do I need to know if the primer that must go down before the leveling compound will ahear to the OBS subfloor that was painted with Zinsser odor water base paint primer. I'm afraid the primer needed for the self leveling compound won't ahear to the Zinsser water base odor blocker. Unfortunately the can of Zinsser does not give any information on this. I'm worried the primer needed for the self level won't ahear and possibly cause to lift and start to bow. This is the 1st time I have ever tried to tackle a DIY floor. Or would you suggest putting Luan 1/4 underlayment over the OSB. Then do the selfleving to the underlayment

[@Housebarons]

Hey Sharon, Best I can do is make an educated guess. That zinsser primer is meant to be covered by other paint. It is made to stick to, and have paint stick to it. So my guess is - the primer for the leveler should stick to it. We put that Henry leveler primer down on old vinyl like tile and then leveler and it stuck amazingly well. Plus, the leveler is a pretty strong concrete. I expected it would chip around the edges where we spread it more thin than recommended. Never did . And - you are laying vinyl plank over it - should be pretty stable. You could do a small spot somewhere in a corner or out of the way - paint on the leveler primer- then some leveler. After it dries - see if you can pop it up. Actually, we have been walking on the leveler for months now as that floor won’t be covered till we are close to done with the renovation. It is solid as when we poured the leveler. Hope that helps.

[@sharonk526]

I think that's a great ideal to try a small corner. I can't thank you enough for all you input. May God bless you & yours !!! Thank you so Much ❤️. I'll message you and let you know the results 👍

[@k.m7107]

I have the option between the original 3/4” sub floor nd the 5/8ths - 1’ ply I am adding -so I could apply self leveler in between. I can see this at the very least reducing the number of sheets of different thickness I need to order for the second layer of subfloor. What are your thoughts? Only worked with leveler 2 times both concrete.

[@Housebarons]

Hey k.m…, I guess it could work. We’ve been walking on it for a year as we finish this reno and haven’t seen one crack after pouring it on top of plywood. So that would be my first choice. Your call though… Thx for watching!

[@dwaynenero535]

I think I came up with an interesting way to use this leveling compound, please tell me if you think if would work because it's just an idea that I haven't actually used yet. On an old wood plank floor that has some dips and uneven areas I was wondering if before pouring the leveler what if I used redgard or a water proofing product like that on the cracks / spaces between the planks to seal them before using the leveler. Would the leveler have any problem sticking to and hardening up over a product such as redgard

[@Housebarons]

Hey Dwayne, Hard to say for sure. Best way to know is to try it in a small out of the way and see how it works. It worked for us. Sometimes it’s about trial and error. Thx for watching!

[@Housebarons]

Hey John, First - get to the bottom of the cause. Sounds like a bad or long time leak. Can you get to the problem underneath? If not, I’d tear up the floor from above and see how bad the damage is. We’ve seen water damage where the water leak literally caused the wood to disappear!!! If you added floor leveler to such a problem all you get is a collapse. Once all is fixed, you may not need floor leveler at all. Remember that leveler id concrete - it’s. heavy. That’s why we used layers of thin plywood to take up extra space in the dip before adding leveler. Hope that helps Thx for watching!

Converting my garage into a ADU. My bathroom is 5x8 and i am installing a 32"x60" shower pan. I am just leveling the pan only and not the rest of the bathroom. What I did not realize when I put down a 2x4 at 33" across, that the self leveler would seep down below the 2x4. I spent over an hour just trying to keep it from seeping through, what a mess. I did not see anything on the internet about how to level just the shower pad and was completely unprepared to stop the leak. What is the official way to prevent this? The 2x4 was straight. In hindsight maybe i should of taped the 2x4 to the cement or set down the 2x4 and then caulked it and let it dry then do the pour? Your thoughts.

Hey, nice video, however, although you correctly state you can just pour over the wood subfloor. You also don’t show any lath being used, which you point out is not required. The technical data sheet in the priming section specifically states the following: “PRIMING: Prime the wood surface with HENRY 554 LevelPro Underlayment Primer undiluted and allow the primer to dry overnight (12 hrs. min., 24 hrs. max.) After priming with HENRY 554 LevelPro Underlayment Primer, install 3.2 or 3.4 galvanized, expanded diamond metal lath mesh (“plaster lath”) to the subfloor, stapling approximately every 6 inches to prevent the mesh from “floating”.

The primer will gas out an enclosed space for a good 8 hours. It’s not toxic to breath but the smell is very strong and can cause temporary breathing irritation if you stay around for it, and I wouldn’t be surprised if you’d get a bonus headache by hour 8.

[@dejayajay]

Not a bad video, but … if you want a truly level surface, use a spiked roller. It makes a HUGE difference. It constantly ‘breaks’ the surface tension and the product flattens like magic. I’ve done jobs with and without a spiked roller, and I wilL NEVER do a job without one again! Using a screed, and pouring in batches, will inevitably leave you with a degree of high and low spots.

@@Housebarons Hi Dave, thanks for replying; I really appreciate it. The damage is 1 ply deep into the subloor. It is along the glue lines. I have 4 areas/patches that are affected. The largest one is 2.5 inches at its widest and 38 inches long along the floor, and the depth is 1 ply. My subfloor is about 3/4 inch from what I measured. I'm planning on installing porcelain tiles to replace the old ones. Will probably use the Schluter Ditra system over 1 inch plywood (underlayment + my current 3/4 inch subfloor). I'm thinking I can possibly use LevelQuick self leveling underlayment to level out the subfloor in those areas, before screwing on a layer of underlayment to have atleast an inch of plywood depth before I can then install the ditra membrane and then tile. This is my first DIY project so I wanted some reassurance on the plan before moving ahead with it. Or do you think I should change the plywood subfloor since it does seem like there was water damage at some point especially around the toilet flange. The toilet did move around a lot before I removed it. Not sure if it moved bc it was not screwed on correctly or if it had to do with water damage to the subfloor around the toilet flange. The subfloor around the flange toilet, although it shows signs of dried water, is very dry and sturdy though. I'd provide images, if I could. What do u think is the best option to move forward with?

Hey Drew, Concrete is temp dependent. It sets faster when weather is hotter. But at room temp, it will harden in a couple hours but you should wait at least overnight before walking on it.

it is SELF leveler..........wow!

Thank you Mates for your great video and sharing. This really helps me and what i need.

[@Housebarons]

Hey Software…, Awesome! Thx for watching!

[@DailyBrusher]

So, I wonder if the Henry 555 product will flex, with that wooden floor, and not break? Otherwise, that portland cement product will produce a lot of grit and dust and chunks under that floor, in a few years...

[@Housebarons]

Hey Daily, So far so good. Thx for watching!

[@54321Truth]

Its got plastic mixed in for flexibility

[@bashkillszombies]

I'd be more worried about finding what caused that dip and want to remedy it rather than mask it.

[@jpickering80]

Great video! Thanks for sharing the process.

[@Housebarons]

Hey Jonathan, Glad it was helpful! Thx for watching!

[@scottonanski4173]

Whoa. I hope you guys did an asbestos abatement...

[@Candlerman2199]

I did a very poor job of trying to use self-leveling compound on a plywood subfloor. My mix was too thick and it needs to be removed and done correctly. I've tried some concrete remover spray to loosen it up a bit, with little success. Next was a grinder with a diamond disc. Besides the dust, it wasn't very productive. Any advice? Thanks.

[@Housebarons]

Hey Brian, We once tackled a 2 inch too thick pour of concrete by cutting groves about 1 inch a part with a diamond tipped circular saw blade. The hit it from the side with a hammer. Hope that helps! Thx for watching!

[@dirtyburger7528]

I can smell that drill from here lol. Gotta bite the bullet and buy a legit mixer. I went through 2 drills before buying one.

[@Housebarons]

Hey Dirty…, True true! Thx for watching!

[@jtompkins1277]

Get a cheap Harbor Freight Hammer Drill that plugs in for your mixing purposes.

[@Housebarons]

Hey @jtompkins1277 Thx for the tip and for watching!

[@AltruisticWarrior]

Lol I bought a Warrior brand corded chuck drill from Harbor Freight once. Thing started to spark and then caught on fire after just a couple uses mixing paint... I exclusively use Flex tool cordless now with a lifeline warranty. Haven't had a single problem with any of them and the battery life gets me through the jobs.

[@Jack-ge1st]

I see the process and in theory it does indeed level. The real question is, how durable is it in the long term, and will it break up when hardwood is nailed over it?

[@Housebarons]

Hey Jack, Ours has proved super durable! Hope it works out! Thx for watching!

[@chuckbass3101]

no lathe? no fiberglass tape over plywood joints?

[@Housebarons]

Hey Chuck, No. Many many screws used. The pad an engineered floor over it. It will work just fine! Thx for watching!

[@kimchee94112]

Should not be called self levering if it requires so much hand work.

[@Tom-ii6ib]

And horses are self breeding, but if you are dealing with a special racehorse lineage, you use your hands and an artificial vagina just to be extra certain that a pegasus doesn't come flying in when you're not looking and screw up that racehorse lineage. Ever seen a racehorse with wings? Me neither. So as long as this stuff is thin enough, it ought to self level, with or without manual intervention

[@frankvandalen6524]

If it's so self leveling why have to screte it? Could you make it just a tiny bit more soupy, and have it seek its own level like water? Thnx

[@Housebarons]

Hey Frank, True. It’s all about preference. Our screeding was to “hurry it along” so to speak.

[@danlu1578]

How did you secure the plywood to a concrete floor? It's not like screwing into OSB wood floor.

[@Housebarons]

Hey Dan, We laid down plywood over existing wood floor. The finished floor we plan to lay down over the concrete floor leveler will be engineered hardwood which is a “ floating floor “ -, a click lock flooring over a thin pad. IF we were choosing a different hardwood floor, glue could be used. But that seems a bit of unnecessary work for our taste. Hope that helps. Thx for watching.

[@rolandamor7851]

@@Housebarons do you know if the henrys hold up against a solid hardwood nail down?

[@cdbrudis]

Why not use spike roller and let product do what it was meant to do ,(self level).

[@Housebarons]

Hey cd…, That’s an option. Thx for watching!

[@bobkidd7075]

Will henry 549 work similar to this

[@Housebarons]

Hey Bob, Henry 549 looks to be a faster drying ( 15 min ) mix compared to what we used. Doing our whole floor, I would prefer to not be time constrained as jobs always take longer than I plan. The benefit is that the Hebert 549 goes to a feather edge whereas the 555 had down to an 1/8 inch edge limit. So pros and cons. It looks like Henry 549 bonds to many materials. Just double check that will work with what you are doing. It has its pros and cons so it looks to be a personal judgement call. Thx for watching!

[@bobkidd7075]

@@Housebarons thanks! The area I'm doing is small about 4 x 6 1/4. I'm a DIYer, what exactly is feathering?

[@Housebarons]

Hey Bob, The feathered edge is the outside edge where the material is spread to the thickness of a feather. Some mixes can not be spread to a depth of less than an 1/8 inch ( like what we used) or else it would crack and flake. What you are using can have a paper thin edge which makes it nice for an unnoticeable transition from existing floor to the floor leveler. Hope that makes sense.

[@molonlabe7750]

I level for a living. And will say, you have the compound way to thin. Just a note

[@Housebarons]

Hey Molon, Thx for the input and for watching!

[@tonywarrior4647]

Yeah right. I doubt that woyld level as well as these guys did it.

You don't know how to use a screed. You have to make a back and forth motion as you move the "screed" along.

What a MESS !!

[@ChillyDippers]

Didn't mix properly. Or this is crap product... If you have to scree it's not self leveling now is it.

[@bitchasz3shat3]

Is there a real difference between screeting and agitating? It should be agitated shouldn't it?

[@steevemachine118]

This s a perfect example of how NOT to do a subfloor! OSB should NEVER be used as a subfloor!!

[@badboytommy187]

That is a bad way to level your floor ! What happened the second contractor to fix that floor ? 🤔😢👎

[@jerseyjim9092]

How do you work with that annoying music playing?. I have to mute the video just to watch.

[@portagepete1]

This place should have just been torn down and build new.

[@54321Truth]

No self-leveler is made to go over OSB. Why are you tipping the board instead of just laying it flat and making a sawing action back and forth?

Hey 5432…, It worked fine for us. Thx for watching!
