New construction and the flatwork contractor got over-confident and the 2500sf slab got away from him. Short story is that I've got two issues now resulting from non-flat floor. 1) Installing engineered wood (glue down) and need to flatten the floor. Will not be able to grind down high spots because concrete sub also messed up the placement on the radiant floor tubes and I don't trust that they are deep enough in certain spots. Not willing to risk grinding into one of them, so I've opted for a micro-topping instead. 2) One room is supposed to have stained concrete as a finish surface.

ARDEX Americas entered The U.S. Market in 1978; as a result, America’s first self-leveling concrete underlayment was born. Today, ARDEX K-15® Premium Self-Leveling Underlayment continues to be the most specified choice for. Defender of texel forum.

HO isn't pleased with the rough patches that currently exist. Consequently, looking to install micro-topping there too. I've got a choice between two products really.

Ardex K-15 or Mapei Novoplan Easy. Looking for the pros and cons to either. Novoplan is easier to find here and cheaper, especially when considering the shipping costs on the Ardex. Will both work as a residential wear surface? Ardex is a great product and I have nothing bad to say about it.

If it's within the budget and available, you won't go wrong using it. I use Novoplan Easy as my main go to SLC. It dries to 3200 psi after 7 days and 4000 psi after 28. That should be more than sufficient for most floor coverings. You can drop engineered flooring on it after 3 days. Just remember regardless of what product you decide to use, you will need to prime the existing slab before pouring the SLC. Also, the existing slab needs to have been cured for at least 28 days before you can apply anything.

You should have no issues no matter what product you use.win-win!
