Bathroom Remodel Floor leveling
This works weel but I recommend having two people during the application process. One to mix and one to spread the material. My application could have been better if I'd had another person to have the second batch mixed up. Without help you have to pour thinner layers to ensure the top is level.

Please read the directions carefully!! My other have read everything but the part about a 10 min work time.. Let's say that is not the time to take a break..half the mix hardened before HE git back to it. I on the otherhand found it easy to work with and did a wonderful job. I cant wait to install my new floor. It gilled all the cracks in the shiplap (100 yr old house) and really helped to semi-level the floor. I didn't expect even that much. We had enough from the second bag to put some in the basement...tile is next on the list. Love my new floor!!!

Not completely level but smooth!
Tore up basement carpet and found weird patch work around the perimeter of the concrete floor. There were also low spots here and there. I scraped for weeks and used several products to try to get the old carpet glue up but in the end we decided to pour over it. We did prime with the Henry primer suggested. We (2 of us) used 5 bags. We definitely could’ve used 6. We even bought the 5th bag as our extra. Buy an extra 2 bags just incase, return if you dont use it. My boyfriend mixed and I poured and squeegeed it around to help it flow. It set up WAY quicker than 10 minutes, I’d say about 5 and we used freezing water so we’d have as long as possible. We let it dry for 24 hours. It is insanely smooth! Unfortunately it didn’t level itself. I suggest using more water so it runs better. We still have low spots to fill, but our major issue was the perimeter which is smooth and level now! I’m not sure why some places it worked and some didn’t. We were extremely consistant with our water, mixing, and pouring. We’re so glad we did it. Once we fill these lower spots we can lay our luxury vinyl!

    This works perfectly.... However, don't make the same mistake as I. The first bag cracked and split all over the place. Then I figured the old hardwood was so dry that it was sucking the water out of the mix. So, I put down two layers of 3mil plastic. It shrunk up like an old wilted flower and cracked something terrible. I then decided to follow the directions (what a novel idea, right?). So, I paid the $10 for the Henry 554 primer and bought $4 worth of galvanized chicken wire. Mixed the Henry 555 for the third time, and the result was a perfectly smooth and level floor. Who would of thought a $10 bottle of primer and $4 worth of 1/4" chicken wire would make all the difference in the world? Easy to use, easy to mix, good stuff, JUST FOLLOW THE DIRECTIONS!!!!!

    Don't Use over Vinyl Flooring!
    Our kitchen floor has three different coverings on it--bare subfloor, places where the homeowner tried to level it years ago, and sheet vinyl. There was nothing on the bags or these reviews that said "don't use over vinyl" so we just primed and used the LevelPro over everything. Where it was wood or even the existing self-leveler, it worked GREAT. Where it was over vinyl we got huge bubbling and warping. We have to break it up and pull it up, including the vinyl, and do it over. But we WILL do it over using the same product because it works like it's supposed to when you use it over wood. For 160 square feet of kitchen we ended up using 12 bags and 4 people. It went very quickly.

      For best chance of success, come prepared
      Used three bags of this to try to level my 123 sq ft home office. Depending on project size, be sure you have enough man power to get this properly mixed, poured, and spread. My father and I did not have any additional help. Either we didn't mix it long enough or we didn't use enough water. Some tips online suggest to add the powder to the water a little at a time as you mix it. Had we had another person to do this and hold the bucket (It spun out of control and flung product all over my bathroom - but I will say it wipes up easily), I think it would have mixed better. The 10 minute set up time makes it ridiculous to try to mix and apply. The good thing is that you can pour one section, let set up, prime the adjacent edge and pour another section. I think we would have been better off had we done this also. Also .... Frog Painters Tape is not a good tape to use to cover seams/holes. We had areas pucker up and crack the product. Might be a better practice to caulk the holes or seams before priming.

      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.
