Rated 5.0 out of 5.0 by Excellant self leveling cement After looking at the reviews over the other popular product, this had lesser poor reviews so I gave this a try. I also bought the Henry 554 and applied over 360 sqft of space. Poured a total of 10 bags of Henry 555. Using a 10 gallon plastic garbage can, Here's how I went about it after watching the video several times. The interior temperature was about 65F and the floor temperature was about 60F in the basement I mixed a small quantity to even out the recessed crevices at the base and waited for it to dry. Having certain I'll be able to mix the Henry 555 without any unmixed cement stuck in the crevices, I proceeded to mix 2 bags with 10 qts of water. I used the metal paddle from HD and a 1/2 inch corded drill and mixed everything until it was consistent. It didn't need 2-3 minutes as they recommended, probably about 1.5 minutes. I poured half of the mixture and rolled it with a 20" wide spiked roller that I purchased online. It was extremely useful as the anti splash also worked as a gaged spreader while the spikes on the roller took care of the surface tension to allow the mixture to flow evenly and feather the edges between pours.

Rated 5.0 out of 5.0 by bathroom is done! I tried three different self-leveling cement products and this is the one that did exactly what I wanted it to. I t mixed well, flowed like a liquid and dried smooth. Now I can put vinyl tiles down. October 19, 2014
Rated 5.0 out of 5.0 by Easy to use This product has not been reviewed since October 2012 so I figured I would here in March 2013. I am a complete novice. Follow the directions and you cannot go wrong. Do use a drill to mix it. Hand mixing won't give you the smooth consistency needed (unless you are King Kong). When you start to mix with the drill, start from the bottom up at slowest speed on the drill. Work up in circular motions and finish with the very top. It should look like pudding you cook on the stove top just when you turn the heat off. Don't forget to prime with 554 and feather the edges with a trowel. When your spouse comments on how smooth the surface is, tell him/her you spent hours getting it to look that way. March 22, 2013
Rated 2.0 out of 5.0 by Easy To Use but not meant for Asbestos Tile Floors I bought this product to go over a worn out asbestos tile from the 1950's. This stuff is easy to mix and apply and did an amazing job leveling out my floor. The problem was it started to peal up the next day. I called the company's tech support department and they confirmed that their product is not designed to work on asbestos tile. Even if I had used their primer product (which I didn't) it still wouldn't work according to Tech Support t wish their bag and or web site said this product can't be used on Asbestos. The downside is I bought and applied over 7 bags of this stuff. And granted now I can't get my money back. If I had a concrete or wood subfloor to level I would surely use this product.

Rated 4.0 out of 5.0 by Level Pro After reading all the comments and watching how to use on UTube, I avoided any major problems, but this product is labor intensive. I mixed and poured by myself, but could have avoided some stressful moments with a helper. Mixed and poured 7 bags for 2 separate projects and after a week, holding up to foot traffic and cold wood underlayment. Amazed at how product settled into my level line that I had painstakingly drawn on the walls of the unlevel floor. Tiled one of my projects the next day and had no problems with the surface or adherence of the mastic to the LevelPro product. ?? Still trying to find out the difference in LevelPro 555 and 554. Bought one bag by mistake, but saw no difference. January 29, 2014
Rated 4.0 out of 5.0 by Easy and ... Before using this product I researched it and watched YouTube videos in which I reccomend to everyone. I used this on wood floors so I screwed my floors down to secure them and primed the wood with the pink primer and waited the 12 to 24 hours dry time. I nervously mixed the bag in a 5 gallon bucket with the exact 5 quarts of clean water that the bag recommends. And stirred it with a drill and metal stir stick. Mixed very well. I poured it on the floor and manipulated it lightly with a 2x4. It does the rest. I was very happy with this product. Did what was said to do. I think the bad reviews are from people who don't wanna read the directions on how to use it. A 2 year old could probably use this. I am vey happy and will use again. I recommend to buy an extra bag in case. I made that mistake and had to run to the store to get another. Take it back if not used. October 29, 2012
Rated 5.0 out of 5.0 by Very useful and easy to use. I am remodeling a 65 year old concrete former garage floor for a new bath. The old concrete was seriously cracked and was very out of level. I was able to use this Henry and the floor is now great. It was especially useful to provide a base for a new shower unit. Absolutely does what it advertises, just follow the directions. I have used 5 bags so far with maybe 3 more to go. It is kind of expensive but really does the job. July 14, 2015
