StyroPrime

StyroPrime is an optional base coat for the StyroSpray 1000 hard coating product. It is a water based acrylic latex rubber coating formulated for fast drying and high adhesion to cut or carved foam surfaces.  The StyroPrime seals the base surface and prevents unwanted air bubbles from floating from the carved foam surface as the hard coating is applied. The sealer also allows the StyroSpray 1000 to easily flow across the surface and enhances smoothness of the final cured surface. Standard latex water base house paints or other rigid clay filled paints are not recommended as primer/sealers over EPS foam. Rigid sealers do not allow for thermal movement and flexing of foam surface, they may cause de-lamination or pealing of the hard coat surface.  StyroPrime sealer dries to a rubber consistency and will not crack off the foam surface like ordinary house paints. StyroPrime is not required for adhesion or bonding of the StyroSpray 1000 hard coating it is optional and should only be used when a smooth surface finish is desired.
