Flexcoat performs well over concrete, primed metal and primed wood. It contains no plasticisers, so it will not become brittle with age or exterior exposure. Compatible with all Rosco paints used either as tints or surface coatings, Flexcoat can also be mixed with rubber and foam granules to provide a strong and flexible bonding agent. It is weatherproof and provides a flame retardant coating over most substrates.
