The Durakrete Grey Overlay is a polymer-modified cementitious overlay and is used as a base layer to create the "grout" effect for the floor.
Apply the Grey Overlay, then place your outlines on top (wood plank, flagstone, pavers, stone, tile, etc.). The Grey Overlay can also be used as the main overlay of your project to achieve the desired effect.
Durakrete Overlays are highly flexible and durable allowing them to withstand cracks or chips. For use over existing concrete such as patios, walkways, driveways, garage floors, interior floors, and pool decks.
