Q:Why will metal spikes leave marks and rubber cleats not leave spikes in the slu? Cleats aren’t long enough in some areas.

1 Answer
Answer This Question

A:  Metal spike may pierce primers and cause a bonding issue. Both rubber and metal will not leave a mark after smoothing the product.

          This product is great and I do not know why it is not stocked in any HD in the area where I live (Western Washington). It mixes well and pours easily. It leveled out as poured fairly well and ended up perfectly flat for the 12'x12' that we did. We poured it over a Heat-Matrix uncoupling mat which made placing the tile much easier than placing the mortar into the mat first then placing the tile. It sets up quickly so we mixed all 9 bags at once. It has been installed for about a month as of this review. Very happy with the result!

          Great solution for self-leveler without metal lath mesh needed
          I am a DIYer and was looking to remodel a small powder room (pictured). The plywood subfloor was uneven due to settling over the years, so I used Henry 542 to level the floor ahead of my Ditra underlayment & tile installation. As someone who has never used self-leveler before, Henry 542 is incredibly easy to use and works as advertised. I liked it because it did not require metal lath on the subfloor for structural support like other solutions. Follow the directions, including priming the wood surface with Henry 564, 554, or 543 solution (sold in a bottle) using a short nap or foam roller. When mixing the water and the 542, make sure you measure the amount of water per the instructions. It was also important to have the appropriate barriers to prevent the mixture from flowing everywhere. It is a runny consistency and goes wherever gravity lets it, so you have to build containment. There are solutions out there that are easy to use and I used one which was essentially styrofoam that let me cut the excess/top away after the leveling mix dried. Also worth nothing, you can spot-level the floor and do not need to cover the entire surface as I did. Finally, as silly as it sounds, practice your pour with an empty bucket!!! Make sure you know the path you are going to pour before mixing and pouring. You only get one shot and any attempts to smooth after pouring will be a challenge as the mixture starts to harden pretty quickly (see my picture and on the right where I messed up a little). My room was small enough where I did not need to walk in the mixture, but I have read that soccer cleats should be worn to prevent permanent imprints in the surface if you are walking through it. Overall this was a very easy to use product and worked as advertised!

            Mixed well per the instructions. The key to an even pour is to use a gauge rake.

            NO lath required
            Purchased because my leveling job would be a thin pour in some spots(only 1/8th of an inch). I didn't think lath would properly seat in the thinnest areas. Glad to find a product not needing lath

              The product was more difficult to level than promoted on the site and in comments.

              Sets Up to Fast
              It worked well. The only reason I am giving it a 4 star is because it needs to have a little longer working time. I used it on an upstairs bathroom floor. I had to mix it in 2 separate buckets outside so it was easier to handle and not make a mess inside, then carry it upstairs and pour it by myself. It was all I could do to do it fast enough. In my opinion it needs to have a 10 minute longer working time before it starts to set up.

              It did not “self-level” as it says over our wood floors. Very disappointing.

              This self leaving compound was pretty easy to use and gave me an almost perfectly level floor. As a DIY this was my first time to use product. My floor had the cut out holes for plumbing so I stuffed them with packing foam. Worked well on all holes except the 4” for toilet. The foam succumbed to the pressure of the compound thus lost some product and had to make a quick adjustment. If I had this situation again I would take the time to fill hole with matching pvc pipe size. Product is a bit expensive, but I do recommend it.
