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.

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.

Trash can would be best. You can mix it all at once, but you'll need a strong drill and a large paddle to mix it fast. And it'll be a couple hundred pounds so have help. This is the RS for rapid set. 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 found that Read More

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.

It isn't intended for this purpose. That said I did it in my garage over 10 years ago, painted it with epoxy paint and it has held up. I told the Custom's representative what I'd done and his first words was,
" It isn't warranted for that use." Then he asked me how I'd done it and was a bit impressed.

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.

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

CUSTOMER REVIEWS

Rated 3.8 out of 5 by 206 reviewers.
Rated 4.0 out of 5.0 by them floors get flat there is nothing worse for a tile installation than having a floor that isnt flat. unless you are especially skilled in the concrete arts, there wasnt much you could do, until now..... clean the floor, prime the floor, mix with the appropriate amount of water and pour it out. fast drying, do not use a fan to try and accelerate the dry time. it will handle business on its own. its not cheap but it can be worth it to give you a floor that looks like a high paid professional was under your employ for the last couple weeks. bonded well to existing concrete floor, didnt try over carpet..maybe next time. June 14, 2016
Rated 5.0 out of 5.0 by product works great - just as advertised This product worked fine and was exactly what I needed to create a level substrate for the porcelain tiles I laid in my entry hallway. Before using it I read the customer reviews and watched a lot of YouTube videos. Regarding all the negative reviews and warnings - I would say that most of these reviews are written by people who either don't know what the product is intended for, don't know how to use it, or simply can't follow directions. For example there is one negative review where the reviewer claims they followed the instructions exactly by using 5 liters of water for a 50 lb bag. However, the instructions don't say that. They say to mix 5.75 quarts of water to one 50 lb. bag. 5 liters = 5.28 quarts, which is significantly less than 5.75 quarts. No wonder it was too thick! You don't need to be an expert or a contractor to use this product. Just digest all the instructions, read some reviews and online forums, and watch YouTube videos, so you will know what you are supposed to be doing. June 15, 2016
Rated 4.0 out of 5.0 by It did what it said it would do! After reading some of the other reviews I was a little concerned about trying this product but I am glad I did.It worked well.I just did not try to do too much at one time to avoid it drying out too fast. I am happy. June 21, 2016
Rated 4.0 out of 5.0 by First Timer Really does find level - even where you don't want it to. A little hard to mix as instructions are for mixing full bag only and I only needed enough for 2 sf. so I wasn't sure on consistency. June 21, 2016
Rated 1.0 out of 5.0 by A total waste of $110 We just wasted $115 on this product that was difficult to mix, shaped and contours. It was not funny how it dried so fast. We had to quickly removing it from our surface to avoid a mess. We stick to regular cement that can be contoured and shape easily. I will never spend money on this product ever again. How do you get your money back on wasted hard concrete. We are so disappointed but we learned our lesson. June 3, 2016
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 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 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
