2 years ago, I used LevelQuik RS to level/smooth out a concrete foundation so I could install stick on vinyl planks (terrible idea). The resulting floor has plenty of waves and high spots. I'm now looking to do the entire house in an hdpc vinyl plank.
I feel I have to remove it. I'll also be removing tile right next to it, so I'll want to match the elevation there. How should I remove the layer of LevelQuik? It's 1.5mm thick. Should I go at it with a Power chisel before grinding it? Will it likely chisel up easily, separate from the underlying concrete?
