can this be used to level a garage floor when a car will be driven on it?

Asked by Jim April 25, 2021

As long as existing cement is solid this will work great. Start at lowest elevation and pour your way out. Have a trowel handy to aid material in flowing. Great stuff once you learn how to work with it. Really durable too.

Can i pour this over old vynil sheet flooring

Asked by Tiny March 29, 2021

Please ...NO!!! Vinyl sheet flooring is an unacceptable substrate for just about anything except maybe carpet. The Levelquik will crack to pieces and the missing pieces will cause indentations in the new flooring if left in place. It shouldn't be very hard to scrape up the old flooring. Please remove the old flooring, then evaluate what you may need, if anything, below the new flooring to keep it smooth.

LevelQuik RS 50
Great product didn’t have any problems. I had a 15 gallon bucket mixed to bags at a time with 3 gallons of water concrete flowed like a champion
by Milton
Consider before purchasing
The pro of this product is that it finishes with a little texture, so if traction is a concern it will be a good choice. The negatives are, it does not self level, no matter how thin you make it. It is very difficult to get this to flow out even. It tends to be soft after curing and can be rubbed off if you do not use latex additive. It is not as hard as other products It is not as smooth, but has a texture. For some applications this is a challenge, it also does not feather as well as other products. Overall I was not pleased as we used it to level a concrete floor that was over 100 years old. It did not perform any where near as well as another product we tried at the same time. It left a slightly rough, soft uneven finish.

Use a bow rake!
First time I've used a floor leveler. I followed directions to the letter. I had 3 helpers and lots of buckets. I used a laser level to calculate bags. Minimum depth is about 1/8' to 1/4" Worked great.

Great product!!! Decided to relevel a hall-bathroom floor for marble mosaique, rather than deal with 50 y.o cement base. Two bags bought

Listen to others! 6qts water per bag!
I have a 20.5x13.5 room that was recently mudjacked and I needed to level the floor about an inch or more. I used 35 bags. I did 18 bags first run then 17 the second time. The second layer I did after 3 hours so I did not need to primer a second time. I may need more bags for a small skim coat to finish it off. This would be easier with multiple people but I did it completely by myself, so it’s possible! I’ve never leveled before besides watching YouTube videos. As stated in title use 6 qts water per bag. My method to do it alone was use a small trash can and mix 2 bags at a time. I did 3 one batch but the trash can is incredibly heavy so I stayed with 2 per batch. Keep the trash can close to where you need to pour because it’s very heavy and I just tipped it over. Use a 5 gal bucket with quart measurements so you can make batches fast. I used a 24” metal leveler with a long paint pole to push it around but the leveler does most of the work for you. Harbor Freight mixing drill did the job with ease. Move fast because it sets up fast. 35 bags cost me $1000 but to have a level floor to lay my vinyl planks is priceless. Would recommend for the DIYer at home. Stuff is very solid once dry

Worse than when I began
The directions are an absolute farce. I followed them exactly, and ended up with a mixture that was much too thick to disperse on it's own. When I spread the mixture with a squeegee, each pass left deep hills and valleys that wouldn't back fill or level on their own. The floor is 100% worse than when I began.

Easy to work with
I messed up the very first time using this product because I did not follow the instructions for the quantity of Water to use. Once you mix it in the right water quantity is really easy to work with. The results are even, solid And smooth.
