What does self-leveling compound do?
Self-leveling compound can create a flatter plane for tile when the floor is cleaned, primed, contained and suitable for the product.
It is not liquid mortar poured over every problem. The substrate has to be evaluated first, and the material has to be mixed and placed correctly so the tile has a better surface to follow.
This can matter for large-format porcelain tile, tile floor installation and heated tile floors.
