PREP-WALL™ is a professional interior surface conditioner that improves the quality of the drywall finish. It provides a smooth, sandable surface, eliminating problems often caused by porosity variations between finished joints and untreated drywall. PREP-WALL is recommended for new drywall to minimize texture variations from drywall face paper and joint cements. It is not, and should not be considered as a sealer, primer or a finished top coat.
