Rated 3.8 out of 5 by 141 reviewers.
Rated 5.0 out of 5.0 by Great stuff! I didn't have a very large area to level but since it's something I've never done before, I was a little nervous. I purchased the primer along with a couple bags of the mortar. Some reviews say to use the primer and others say it's not necessary but I tend to err on the side of caution. Whether you use the primer or not, this material is incredibly easy to work with. Make sure you have the right amount of water and this is an easy one man, one bucket job if you have less than 100 square feet. January 27, 2015
Rated 4.0 out of 5.0 by Not a bad product at all. Just learn from my mistakes Tools you will need: 2 people Measuring bucket 1/4 nap paint roller for primer Egg Beater style mixer Quality 1/2" corded drill (Milwaukee, DeWalt, Craftsman, etc) Libman Flex Blade Squeegee (this worked perfect) Mixing and pouring buckets (depending on size of the job) I bought a cabin in 2010. The main room sits on a slab that at some point, cracked and settled. I've been keeping an eye on it and since I've had the cabin and it hasn't gotten any worse. The previous owner had vinyl tiles down and I want to upgrade to ceramic. Not knowing whether the existing tiles contained asbestos, I was reluctant to pull them all up. So I decided to only remove the ones that were over the crack. My nephew sprayed them down while I removed them. I filled the exposed crack with a concrete silicone to prevent the leveling compound from entering. You will see I used duct tape to cover along the base of the walls. You will need to do something like this because this stuff will seep into any crevice it can find. I'm putting cedar tongue and groove on the walls once the floor is installed so I didn't really care about the duct tape showing. After reading the specs for the levelquik primer, I noticed that it did not state it could be used over vinyl substrates. So I after extensive research, I bought some Ardex P82 primer. This stuff worked outstanding for my application. The levelquik primer is probably fine over wood and concrete subfloors though. I did quite a bit of research (read forums, watched youtube videos, etc) before attempting this job. I knew I couldn't do the entire job in one pour. Being I had a large area to cover. I bought a 20 gallon trash can to mix in. I mixed 4 bags on my first pour. The directions state 5.25-5.75 quarts of water per bag. I went with an even 6 quarts in hopes of buying me a few extra minutes to work with it.. I bought an egg beater mixer with a 30" shaft. to blend it all together. You will need a high quality drill to mix this amount at once. It doesn't have to be a super high torque drill but a high quality standard corded drill with a 1/2" chuck will do the job. We poured all the pre-measured water into the trash can. While I was running the drill, my nephew started dumping bags. Make sure you mix this outside as dust will fly everywhere. I bought two 2 gallon buckets so my nephew could fill one while I poured the other. Once the trash can was light enough, we dumped it. This stuff will drip everywhere. So if you're going through a finished area of your house, make sure you put down something to catch the drips. The first pour went flawlessly. The biggest mistake I made was I didn't wait long enough to do the second pour. I wasn't sure how long to wait, I started the second batch to soon. I waited about 30 minutes before starting my second pour. This time I did 3 bags. I used the same mixing ratio (6 quarts/bag) and I started pouring. I got a little excited and poured to much by the first pour. When they overlapped, I could see there was a lip. So I used my squeegee to pull it back. The problem was the first pour was still soft and I dented it up reaching out and pulling back the second pour. The squeegee did a great job collecting the compound and I could feather it really good. Besides the little dents, you can't even feel a transition from one pour to the other. My advice is to wait at least an hour before attempting a second pour. I don't really have any complaints about the product itself. The only thing I wish they had was better instructions. I downloaded the instructions from the custom builders website and it doesn't say how long you should wait before pouring another batch. It just says if you wait more than 24 hours, you will need to primer the existing compound. April 6, 2015
Rated 5.0 out of 5.0 by Works Great! This product works wonders on "wavy", uneven floors. Make sure to follow the mixing instructions on the bag, as they have recently changed the amount of water needed per bag. If you have one person mixing and one dumping the bucket and spreading the installation is even easier. December 31, 2014
Rated 5.0 out of 5.0 by Impressive results! I was a bit nervous to tackle a big leveling job in our basement but am so glad that I did -- the results are fantastic! We had an uneven concrete slab previously covered in carpet that needed leveling prior to laying vinyl planking. With the help of two friends, I was easily able to mix and pour four bags in each of two rooms. I mixed using a corded drill; one friend poured in the concrete mix into a 5-gallon bucket; and a third friend measured and pour water. This worked perfectly, and I was able to feather the edges and make sure everything was level prior to the concrete setting. All-in-all, we fixed a 1" - 2" unevenness in both rooms and have a nearly level subfloor for our new flooring. Highly recommended in conjunction with the floor prep mixture. October 14, 2014
Rated 5.0 out of 5.0 by Follow the instructions and you will be amazed when finished. For the pro to the home owner this is a product you can depend on. I am a home owner, in construction all my life but 1st time ever doing this type of job. DO,s -Read the INSTRUCTIONS twice so you dont forget the steps. Follow the INSTRUCTIONS so you dont mess up. Have a container marked with the amount of water needed per bag acordding to the INSTRUCTIONS. Have a 1/2" CORDED drill WHEN you start. Have a helper, one mixes while the other adds the water and product. Have a squege ready just in case you need it. Have the border of the area sealed off befor you start. i used painters tape. ( it will escape if it can ) Have a mask Mix away from the job area Buy more than you think you need, then return unused bags.( you dont have time to run back ) DONT,s - DO NOT STOP UNTILL JOB COMPLETE. My girlfriend and i used 14 bags for 1/2 of our unlevel basement floor. Floor looks great like a pro job untill you see where i STOPPED and then started again. gonna buy more next week and fix that area. been 8 mths now and has held up to alot of traffic. Excellent Product. April 18, 2013
Rated 5.0 out of 5.0 by Easier than I thought with a great smooth finish Debated about lifting some existing tiles and leveling the floor in a basement bathroom. Almost seemed like too much trouble. Couldn't have been further from the truth. Tiles came up easily and this Levelquick was easy to mix with cordless drill (needed both batteries) and the mixing bit the associate from HD gave me. Added the mix slowly to the water (three heaped garden trowel fulls at a time) , mixed well, and went on the floor smooth. Used a hand hand grouting tool to spread it out a bit, but didn't have to do much. Re-tiling should now be much easier. Very happy. November 4, 2012
Rated 5.0 out of 5.0 by 6 X 8 ft With 3/4" Droop, Worked Great First time I ever did this. Split 50 lb bag into 2 batch. Poured the first 50 lb in the center & it self leveled to where the 8 ft 2x4 I was using for a float didn't touch it. Went & got 2nd bag, mixed & poured that. Spread it with a 3 ft squeegee & drug the 8 ft 2x4 back & forth across the pool a couple times. Came out perfect. March 16, 2012
Rated 4.0 out of 5.0 by it's not a perfect science I use self leveling products frequently and sometimes they work perfectly, sometimes not so much. Read and follow the directions to the letter and have help on hand if you're mixing more than 8 bags for a lift. The most common mistake is NOT mixing at the prescribed speed for the prescribed time. 800 rpm's is faster than most heavy duty drill motors turn and 2 minutes seems like forever. Lastly, maintain a wet edge to assure mixing of batches on the floor otherwise it looks like an alluvial plain after the water recedes. March 29, 2015
