Davies Flexi-Dry

Elastomeric Mastic Waterproofing

DAVIES® Flexi-Dry™ is a heavy-bodied water-based elastomeric coating that cures to a rubber-like undercoat membrane for use in positive waterproofing concrete or masonry surfaces. Its high solids content covers any capillary crack on the surface, creating an elastic sealing membrane-impermeable from water. It dries to a smooth finish with high bonding strength while maintaining good elasticity.
