Prep Coat is a multi-purpose drywall completion coat designed to improve the quality of the drywall finish. It is recommended for use prior to the application of texture or decoration to minimize texture variation between finished gypsum surface and gypsum face paper. It is not, and should not be considered as, a “sealer,” or an architectural coating.

Prep Coat provides a smooth, sandable surface, eliminating problems often caused by porosity variations between finished joints and untreated gypsum wallboard paper.
