Acrylitex Smooth Wall is a hi-build PVA applied in a one-coat production spray application to take a Level 4 gypsum drywall finish to a Level 5 as described by the GA-214 and ASTM C 840 guidelines. Smooth Wall eliminates the need to skim coat, sand, and prime the surface to achieve Level 5. Regardless of the surface, Smooth Wall provides a sealed, uniform finish over finished joints as well as bare drywall, providing the best possible surface for finish coats.
