ARDEX Liquid BackerBoard® Self-Leveling Underlayment - Demonstration

[@ednja]

I'm repairing a small sundeck that has 2 small dips about 1/4" deep. The deck has plywood and some of it still has old fiberglass. I will be using primer and deck coating instead of fiberglass. I bought some floor leveling compound and it says not recommended to use over fiberglass. There is some fiberglass and some wood where the dips are. Can I still use the floor leveling compound if I first coat the fiberglass with primer? If so, what kind of primer would you recommend. Also, how thin can the floor leveling compound be? Does the floor leveling compound crack after it's dry? Can I use body filler to feather out the edges of the floor leveling compound after it's dry?

[@samattos1]

I'm just here for the bass line.

[@ARDEXAmericas]

Haha!

[@espjason]

Steve Mattos its all about the bass about the bass

[@seanhazelwood3311]

Or, better yet, simply install a temporary form board (coated with release agent so the material doesn't stick to it) across the entry and pour enough material in to level the floor, It will self-level. I've done it with other brands and it works fine.

[@jjs777fzr]

Can this be poured over a laminate floor ? The laminate floor has existed for nearly 30 years and its not easy to pull up or scrape out. I'm hoping this product could be applied right over it. Thoughts and comments welcome - and thanks for the video.

[@Mrdubomb]

Can this be used with flex bone and does it go on before or after the uncoupling membrane? Also what will happen if you apply to a feather edge?

[@ARDEXAmericas]

It should be put down and allowed to dry, prior to installing FLEXBONE. It should be installed at 1/4", you can't apply to a feather edge because it is a self-leveling product.

[@Mrdubomb]

@@ARDEXAmericas Can you sand the edge to a feather finish, or apply another patching/leveling product on top of this. We only want to apply the minimum amount necessary. My local Ardex distributor is telling me the primer is not needed, are they correct? Would this eliminate the need for an uncoupling membrane? It seems to me that the flexbone should be adhered first and then leveled, what keeps the plywood underlay and SLC from behaving just like an installed tile without uncoupling membrane 15-20 yrs down the road?

[@ARDEXAmericas]

@@Mrdubomb Great questions - I will refer you to our technical experts. You can reach them at: 1.888.512.7339. They will be able to walk through the ins and outs of your installation and ensure that you have the correct answers. Thanks!

[@mikegordon2554]

So let me get this straight.. Ardex Liquid Backerboard: $46 Ardex P-51 Primer: $52 Ardex T-4 Spreader: $55 Buckets, Caulking, and Other Supplies: $20 A Pair of Cleats: $40 A old tape player to play really cheesy music while installing $8 Total Cost: $221 without tax So it will cost $6.80 per sq foot worth of coverage???

[@oneproudpappa]

That's if you get it right on the 1st try!

[@Evan_Adams]

I did not know P51 could be used over wood. Good to know. I think I need to read up on proper use of primer

[@Scorpiomaj27889]

In my bathroom we're dealing with hardwood that is directly on the floor joists, do I need to lay plastic sheeting or I need to rip out the hardwood and start over? It will take forever to seal every seem.

[@ARDEXAmericas]

We recommend overlaying your hardwood with 3/8" exterior-grade plywood, then filling the seams of the plywood with SKM. Then you can pour the Liquid Backerboard. For more information, give our technical line a call at 1-888-512-7339. Hope that helps! Thanks

[@billreed8413]

We have a upper level of our home that was sagging. We had a additional brace put in at the lower level and the home is very secure. We have been left with the upper level of the home sagging towards the middle. In the bathroom there seems to be a floor level difference of 1-1/2" from the lowest to highest. the whole upper level is "wood subfloor"....what product would you recommend to correct the difference.

[@paszdevil1]

nice video not to sound stupid but i am doing this same project, is the lath on the floor before you poured and how long do i have after i prime it?

[@Maxid1]

What's the learning curve on this stuff? If I have to smooth it after spreading it, it doesn't seem like it's really self leveling. Could I accidentally leave a ripple in it and cause a defect in the dried compound? Also, in addition to needing cleats, what's the tool cost?

[@lancemillward2462]

wont the gib wall board now touch the backer board and transfer moisture up the wall?

[@elzippo488]

what did you do with the shoes afterward?

[@mrohida]

I want to get a couple of those black handled buckets for mixing. Where can I find them?

[@humanyoda]

What makes this product "revolutionary"? It seems pretty much the same as products that have been sold in home improvement stores for many years, if not decades.

[@Dave67AZ]

This one goes to 11.

[@humanyoda]

Dave Lewis What does that mean?

[@Thebig10bill]

I think that is a Spinal Tap movie reference (being a joke). Most leveling compounds of the past could only be minimally applied as to a thickness of about 1/4" as they do not perform well at greater thickness.

[@Dave67AZ]

I figured after a few months someone would stumble across my bad humor. To seriously answer the question, the fact that you can start tiling 6 hours after pouring this stuff I would think is the most "revolutionary" thing. From what I understood (and I'm no pro, so this is just from what I've gathered in my DIY experience) I thought backer board was still used in the past over leveling compounds, but this stuff does away with it (assuming deflection is within specs).

[@humanyoda]

Dave Lewis Thanks

[@Technologyadvisor1]

Hello I have laid leveling compound on a garage floor but I have not used enough and the compound I have put down needs to be raised a few mm as I have not used enough. Can I top it up? it has only been put down 24 hours but I need the level to be level with some concrete that goes round the sides of the garage. please help

[@aldenorcia6193]

Yes,you will most likely have to prime again. Contact ardex to be sure

[@lass-inangeles7564]

Nicely done. Good demo. But it looks harder than a backer board install. Just cut it and screw it down. However, floor looks very level and smooth.

[@JennWest-Liberty]

Can you pour epoxy over this?

[@ARDEXAmericas]

ARDEX Liquid Backboard is approved for floor coverings only, such as tile or resilient flooring. Thanks for watching!

[@grasst1502]

Can just the Ardex patch be used and then add regual backerboard or does it have to be Ardex liquid self leveler?

[@richardparnell3770]

can this be used on osb?

[@JonHerseyMusic]

I just bought Henry Level Pro 555 (a self-leveling underlayment) at Home Depot and the bag says, "Engineered with ARDEX Technology." The instructions call for laying down the lath mesh. Is the Level Pro anything like the Backerboard? Is it the same product, just with more conservative instructions? Thanks!

[@calvinkey5086]

Is there some way that this would have to be rubberized before it can be used over a crawlspace so it doesn't crack as the wood expands and contracts seasonally? Also some of you guys must have an amazing, supernatural skill set if you determined that this plywood flooring was perfectly level by watching that video!?! I've NEVER seen a perfectly level wood floor on a job site. Ever. Close enough to tile without liquid leveler, maybe. But not flawless.

[@ARDEXAmericas]

Hi Calvin, I forwarded your question on to our technical team. Unfortunately , we do not recommend additives be used with our LBB product to make it more flexible. While hairline cracks will develop after installing self-leveling underlayment, when the approved wood substrate is well fastened, there is no concern for debond of the underlayment. If you have additional concerns and questions, please contact them directly at 1-888-512-7339. Thank you!

[@fizzbum6538]

Why not demonstrate this procedure on a substrate that doesn't actually need leveling? Try it over a concrete floor after ceramic tile was removed and trenches for plumbing were cut in etc., then we'll see how easy it is. It can still be done but it's not as easy as in this video. I've done it, lots.

[@gremlinsbreath]

If you dragging and pushing it around the floor aren't you defeating the purpose of "self-leveling"?

[@Dave67AZ]

Only if it sets up before leveling back out. And it sounds like this stuff takes a while to level, so you have plenty of time to work.

[@catrashoo]

Is better using a paint roller.

[@awaisiqbal8934]

It is so called self levelling

[@ashrevlution3456]

I thought the exact same. "Why is he floating it out?".

[@altinsilsile36]

Can this be used for the installation of hardwood? If not, do you supply another product that does?

[@altinsilsile36]

***** the house is raised footing with melamine/yellow tongue/chipboard floors. Can this or another product be poured to level it, so as to install 100% hardwood over it, which will be sanded & varnished.

Where can I buy Liquid Backerboard in the Wilmington, Delaware area? I have been looking around, but can't find it anywhere.

OMGosh... My thoughts exactly...

[@JudiChristopher]

@@ARDEXAmericas OHHHH You did answer (kinda)...

[@mikesmith-st9fb]

It cost $30 then pay the tax, $32.40. It only covers about 3 feet by 1 foot. It only has a depth of 1/8th inch at that coverage. You'll need about 20 bags to level 1 room @ $32.40 per bag. About $648 dollars. If that room has a dip of 1"inch. IT dries fast, so you lose a lot in the bucket. You are better off with leveling the floor with mud and hardibacker. This stuff can get expensive fast.

[@godbluffvdgg]

Exactly! Ardex needs to lower the cost.

[@pinkskys3226]

Spider man

[@Lore-wv5mt]

mike smith thanks!

[@JasonEMoustakas]

Not sure what you are talking about. In 2019 it's about $50 a bag and covers 65 square feet at 1/8. A 12x15 room would take about 3 bags at 1/8 inch. Beats the time and back breaking work of putting in all those screws then taping the seams. Plus it's level. For me the greater cost for materials is worth it plus the end result is better.

[@neznauGde]

Whats the maximum thickness for Self level cab be applied on Plywood??

[@ARDEXAmericas]

Thanks for your interest! Please contact our technical experts at 1-888-512-7339 for these types of questions.

it says 1-1/4 inches

[@markpennine2619]

No, LBB is not the same product as H555. LBB does not require the use of metal lath. ARDEX Liquid backer Board must be covered by tile or wood laminates only.

[@davidallegretti592]

How is this self leveling? I see a man doing the leveling

Can this be used under shower pan (Kerdi). I have a 1/2in drop over 4 ft X 4ft pan 3/4 ext ply. Using Schu/Kerdi foam pan. Thanks.

[@godbluffvdgg]

yep

[@patmac]

Thanks

[@faster7359]

The only time I would use this is to cover heated flooring wire before tile

[@GeneralMartinus]

Wouldn't it be prudent to find the cause of such a off-level and correct it rather then this?

[@Dave67AZ]

What do you suggest...hunting down the original construction company and yelling at them? lol

[@GeneralMartinus]

I was thinking sagging joists from below needing to be looked at. If they are sagging or even damaged, this extra weight is only going to make things worse. Better to fix the cause of the problem instead of covering it up.

[@Dave67AZ]

Gotcha. In most of the cases I see around here the houses aren't old enough to have sagging joists. Builders just aren't as concerned with floors being level and on plane if they're just going to slap down carpet or linoleum.

[@branty2uk]

Nice drum beat.

Does this work on OSB?

[@giuseppenero110]

doesn't it defeat the SELF-leveling feature when your pushing it around yourself?

[@danielzatkovich4659]

There's a difference between leveling and smoothing.

[@garyparker-smith5983]

why is he walking on something he's trying to level?

[@danielzatkovich4659]

Because a liquid self-levels? When you step in a puddle, does your footprint remain on the water? Why is this so hard for people to understand?

[@jnunez1203]

Baddd example youre leveling a new plywood subfloor..dont see the purpose of extra leveling..i would like to see this review on a crocked or not leveled floor😤

[@LosDog14]

This example is to demonstrate liquid backer board versus traditional cement board application. As you can see, the liquid version is much easier. Cement board would have to be installed with modified thinset underneath then screwed down. AFTER, the cement board is installed there is absolutely no guarantee it is flat and/or level. So this video is a perfect example. I have installed kitchen/bathroom floor and walls for 24 years. I have never used Ardex Liquid backer board and yet I can still see why this would be a better way to go simply because you get the added benefit of a flat/level surface to install over. YOU ARE DOING 2 THINGS AT ONCE! Would you rather install cement board then go back and level all the waves and low spots on the floor? Hell no! I would much rather use a product like this one. Zero cement board to install with a self leveling component all in one application. Mario, you clearly are not an installer and missed the purpose of this video. And no, I do not work for or represent Ardex in any way shape or form. Cheap route = cement board obviously.

[@lookout3499]

Use there product often. Finding the correct tool supplier that understands the product was my problem. Ardex, Mapei, etc all wanted you to use there mixing kit. But no one stocks it. Drponline.net has the kit that works well with all brands.

[@GJLCreativeStudios]

[@MrMkd1202]

How do you know it's level? What method do you use to ensure that you have a level surface before it dries? A laser level?

[@da_stanktank4276]

+Doctor Doom It is "self-leveling." It's made for floors that only need to be leveled up to 1 1/4 inch. Once it's dry check it with a level. If it isn't perfectly level you can slap a little extra mud onto your tile before you set it, and level it up then. But, not all of your tile should require this, just a couple here and there, if any at all. If your floor requires more leveling than 1 1/4 inch you should apply the first layer of leveler, and let it set-up/cure. Then apply a second coating on top of the first.

[@stef0608]

We installed backer board to the floor and just tried doing a dry run with the tile only to find that our floor isn't level. The backer board is completely screwed in and not moving. Can I put this on backer board to level my floors before tiling?

[@GJLCreativeStudios]

dont see why not. just make sure you;re not too high already.

[@cinnabar56]

Yeah its not good to work when you're too high

[@mcdatacomm155]

I doubt this actually works effectively to replace a backer board.... just my opinion

Caulk is intended to stick to a primed surface. Classic mistake caulking before priming.

[@agilajaibabu9670]

Kfh

[@Dave67AZ]

The caulk only acts as a temporary seal to keep the leveling compound from running out at the sides of the floor. It only has to last until the stuff sets...less than 6 hours.

[@chrissharp73]

[@lazynut81]

Play wood was perfectly level .why have to level it again?

[@morganrutar6331]

The purpose is not to level the floor in this application. The purpose was to create an underlayment that can be directly tiled on.

[@skintkatz1344]

Just because plywood is level, does not mean the original sub-floor, then floor will still be after after 30 years to 100 yrs. I've pulled up pressed wood with a poured chip floor up to get to my sub-floor and the humps and bumps are horrible. I go for an overkill anyway, but this will go down after my plywood and before the backer board, just to be on the safe side. Ex put down plywood in front bathroom, didn't check level and you feel like you're going to fall off the side of the toilet.

You would be hoping the ply has been installed correctly. Doesn't matter how much you prime if that ply moves you stuffed.

It's all very nice wearing his lovely black leather shoes and nice clean denims with clean hands too, however, where is the protection against reaction to cement based products, splash from the acrylic primer and spreading the silicone with a bare finger is just not the done thing! While I wouldn't want to block anyone in doing their work, health & safety has to be considered when mixing and applying any chemical based product.
