SpecFlow is a cement-based, non-shrinking, self-leveling floor underlayment designed for interior use.

This single-component product produces a smooth subfloor that will accept floor coverings in as little as 12 – 18 hours after installation.

Just mix SpecFlow with water, pour or pump, and it will seek its own level to produce a smooth, flat hard surface.
