LevelQuik RS (Rapid Setting) Self-Leveling Underlayment helps level floors prior to the installation of ceramic tile, natural stone, resilient flooring, carpet, wood and other floor coverings. This quick-setting underlayment can be applied to 1.5 in. (3.8 cm) thick in one pour and seeks its own level in minutes. With proper installation, the use of LevelQuik RS can achieve an extra heavy rating for high impact use in food plants, dairies, breweries and kitchens. LevelQuik RS helps eliminate installation problems such as bond failure, crumbling and staining of resilient flooring caused by the free moisture found in traditional underlayment.

California residents: see  Proposition 65 information

  • Used to level floors prior to the installation of ceramic tile, natural stone, resilient flooring, carpet, wood and parquet flooring
  • Formulated with control cure technology
  • Cures fast and develops high early strength for quick installation

Can you mix the compound in a wheelbarrow or large trash can? Is there a way to slow the potting time?

This question is from LevelQuik RS 50 lb. Self-Leveling Underlayment

August 9, 2014
I'm concerned that I don't have enough time to mix one bag in a 5-gallon bucket, pour and screed, then mix a new batch and pour the new mix on top of the old, potted mix. I'm thinking of mixing 3-4 bags in either a wheelbarrow or a tall (32-gallon) trash can and dumping the whole mix at once. Is there a problem or risk doing it this way? Or, is there a slower-potting version of this compound? Thank you.

There's also an ES (I think it's special order) that is extended set. If you're mixing in one big batch either should be OK to use.

There's also an ES (I think it's special order) that is extended set. If you're mixing in one big batch either should be OK to use. Just make sure you seal up any cracks or holes as this stuff will find a path if there is one - IE around toilet flanges, walls, etc. I usually put some caulk or spray foam around all the edges that way you have some wiggle room. It's easy to rip the foam out after it dries and fill in any voids it leaves with mortar. Read Less

Answer: 
Since the product is little bit costly and we needed to cover quite large areas, we did not experiment and just strictly followed instructions. It hardened pretty fast. I think it does not matter how many bags you mix at the same time if you are able to work with mix really fast.

Answer: 
The areas I did seem to be much smaller than your project. What you mix it in shouldn't make a difference just remember to add the compound, a little at a time, to the measured amount of water stirring as you go. I think a 1/2" drill with a paddle blade will be mandatory for that amount of compound. Your bucket should be round and flat on the bottom so no compound can hide in the corners.

I think a 1/2" drill with a paddle blade will be mandatory for that amount of compound. Your bucket should be round and flat on the bottom so no compound can hide in the corners. I found that using a little extra water slowed the curing time with no ill effects. The water will rise to the surface and evaporate off. Finally, since the mixed product is pretty watery be sure to seal (I used acrylic caulk) any holes or cracks that the mix can escape through. I learned this lesson the hard way :) Preparation is 80% of the job, Good Luck. Read Less

Answer: 
The best way to mix this is by following the directions to a tee. Mix in a bucket with the proper amount of water using a drill with a mixing attachment until it attains the consistency needed. Mixing ant other way would be difficult and would likely not work as well.

Also, you might find some good tips in my review of this on the HomeDepot.com site.
Don't trust it to self-feather. You will need to use a smooth tool. If you're trying to match it up to a surrounding area, I would suggest using a flat 2x4 as a screed.
One bag, mixed according to directions, will yield 900 cubic inches or 14,748 cubic centimeters of material. That's enough to cover a 2' x 4' area with 0.78125" of LevelQuick RS.
You may need to do a little measuring and some math to determine the remaining volume of your space to be filled, but whatever fraction of a bag you need to use, be sure to use the same ratio to calculate how much water to use.

Answer: 
I usually pour enough to go from wall to wall, but If you only have a section to do within a room you'll need to feather it with a float. A rounded edge magnesium float is what I use. Wait til it levels itself for a few minutes than just smooth out the edges so it's flat. Alternatively you can use a metal straight edge or screed and have two people drag it across the floor if you have room to do so. Kind Read More

Rated 3.9 out of 5 by 201 reviewers.
Rated 5.0 out of 5.0 by practice! many of these reviews are written by people inexperienced with the product..the stuff behaves according to the weather..mixing it wetter to make it self-level easier isn't going to reduce its integrity..a consistency of heavy cream is good..just do your job in two or three pours..don't ask it to turn a disaster into a smooth subfloor in one pour..use a mixing paddle and a good sized powerdriver and mix it well! ..pour the deep areas first..use common sense..and screed with appropriate tools and don't overdo it..it can't self-level if you keep messing with it! April 29, 2016
Rated 5.0 out of 5.0 by Great product! The directions were easy to follow, & I was pleased with the results. May 17, 2016
Rated 4.0 out of 5.0 by Don't be scared by bad reviews. Research, Plan & Execute! I was initially scared by all the bad reviews and horror stories on the Internet about LevelQuik-RS. I'm sure we all wish that Home Depot carried LevelQuik-ES instead. I had to level a sunken area in the slab that was rough and uneven. The limited space meant that I only needed three bags of LevelQuik-RS. Keys to success: ● Buy fresh bags of mix from the same batch ● Use recommended Primer ● Make sure the bags of mix are not hot! I let mine sit on the cement slab indoors for a few weeks before I got around to actually pouring. ● Use chilled water. My water was about 63°F. ● Make sure to seal all possible holes and dam off openings so the mixture doesn't escape. ● Use an egg-beater style of mixing paddle (like Home Depot's Store SKU # 123648) and a corded 1/2" drill. Don't use a spiral mixing paddle; if powder does settle to the bottom of your bucket, those won't mix ● Start with a pre-measured amount of water in your 5-gallon bucket. I started with 5.5 quarts in each. ● Add the powder to the water while mixing. Do not do it the other way around! I had to work alone, so I used an upside-down 5-gallon bucket to hold the bag of mix level with the mixing bucket. I cut the top on 3 sides and started the drill. It was messy, but I was able to run the drill with one hand and empty the bag of mix slowly into the bucket with the other. I had enough time to pour each bucket after mixing it before starting the next bucket. I did notice the first batch started to harden from bottom-up after about ten minutes but the top layer was still somewhat mobile. December 1, 2015
Rated 5.0 out of 5.0 by No fuss leveler After watching too many videos showing how to apply self leveler I was hesitant to try. Don't overwhelm yourself with too much information, just mix, pour, and let it dry. The product will do what it's made to do - level out naturally. My gorgeous new 3/8" thick bamboo flooring is laying flat, and the fifty+ year old concrete was far, far from level before application of this product. April 12, 2016
Rated 1.0 out of 5.0 by be aware I followed the mixing instructions on the package and mixed 5 liter of water with 50 Lb of the product. Used it to level deeps in a plywood sub-floor before I put a hardibacker on it. The mixed product did not self level, instead I now raised areas where I had deeps before and that leaves me in worth situation then I had before. Apparently per the answer to one of the reviews, you have to mix it with 6 liter of water. For me it is too late, the damage already been done. November 1, 2015
Rated 4.0 out of 5.0 by didnt work like expected. I used this product to try and level my floor for my shower base, I poured it, spread it to cover entire area, and let dry but after 12 hrs I went to check with a level and the product didn't seem to level area much better than it was prior. April 22, 2016
Rated 5.0 out of 5.0 by Worked like a charm! This worked like a charm. Had chipped old tile off cement floor and was left with the mortar ridges that were under the tiles. Used the floor leveling mix and now have a smooth solid surface to lay new tile without the mess of trying to grind the mortar off the floor. But do mix according to recommendations on the web not on the bag. March 29, 2016
Rated 4.0 out of 5.0 by Amazed at ease. Was scared at first seeing as how this was the first time I've used this product. Floor was large 23ft x 20ft and was very rough to say the least. Had a contractor come in to level the floor by grinding it down but let's just say I got left with a mess. Well to make a long story short the product worked great. Took three of us a little over 2hrs to mix, pour and move around with a 30 inch squeegee. Well the end result was that we were about maybe an 1/8 of an inch off from one side to the other but given the size of the room we were well pleased with the results. Floor looked good considering what we started with and now we will be able to start laying our tile. If I would have know that it would be so easy we would have tried it alot sooner. March 16, 2016
