Customer Questions & Answers

can i install henrys 555 leel pro to a mid center floor that saggs to bring it level with the rest of the floor

I have a 5x5 area in the middle of my kitchen that is sagging. Arrpox 1 inch dead in the center and 1/2 inch meeting up with the assisting floor. I have linolium on the floor now but in the that sagging area i have peeled up the linoliuim and it is a wood type underlayment. I would be applying this level pro that wood sagging area. would this work to make it even with the rest of my floor. And if so can you pour this stuff over the old linolium on the floor if needed to blend it into the area I would be applying this too. Or do you have any ideas of what I could do. thank you
Asked by: Missthing29
Best to find out why your floor is sagging and fix properly. Filling it in is going to add more weight and could make the problem worse.

I read that some self leveling underlayment applied to wood requires wire mesh. Will this be needed when using Henry555

Asked by: Bobbyjeans
According to the instructions, application to wood requires, "galvanized lath mesh."

how thick can this material be applied?

We are attempting to level a floor in a 100yr old commercial building. The space is to become a commercial kitchen. It looks like we will need to fill at least 2" to bring to level.
Asked by: Robert
1/8" to 1/2" is optimum layer of thickness.

How thick can I make this product

I have a 40 x 12 room with a slope between 1 3/4" and 1/4" can I float it that big? How would you suggest sectioning it off to pour 2 pours?
Asked by: Beamer
You have 440 square feet to cover an average depth of 7/8" thick. You would need 20 bags just to cover the top area to 1/4" deep and an additional 120 bags to fill in the deep spots. You are talking serious volume and probably need a cement mixer. Might consider mortar or cement instead. Not sure Level Pro should be poured that deep. Use cement to fill in the low spots and use 20 bags of Level Pro for the top 1/4" of leveling.

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!!!!!

Rated 5 out of 5 by from Works Great Did an eleven by twelve foot area that was sloped an inch and a half low on one end. Turned out perfectly flat and level. It took sixteen bags. Follow the directions and use a rake to spread to a rough level. We did it with two people three would have made it a breeze. The surface is decieving. Resist the urge to trowel what look like uneven spots.

Rated 5 out of 5 by from 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.

Rated 1 out of 5 by from don't waste your money !! we always use custom brand but store was out so we decided to use this product . mixes well and floats out good . but other than that it sucked!!! 90 percent of it all lifted . what a water of money and time . we cleaned it all up re primed the surface and poured custom brand and didn't have any problems . will never buy again and never recommend Henry products . it's like Burning 800 dollars

Rated 1 out of 5 by from Henry 555 Level Pro I have used various versions of self leveling products...this product did not perform well at all...going back to the cheaper stuff. Followed the instructions exactly and the product still underperformed...cracks and lifts...would not recommend. This is the first bad review for anything purchased at HD.
