It allows the bubbles to rise above the surface rather than remaining trapped in the compound, which would lead to a bumpy surface. This makes it smooth without further surface finishing needed. As such, it diminishes the appearance of the bubbles and makes the floor ever flat.

High Compressive Strengths

Self-leveling compounds are not intended as a final floor surface. The materials which make up the compound are not for frequent walking or other foot traffic.
