Due to its high abrasion resistance Tuff-Hide is not very sandable. Areas in need of touch-up, such as nicks, voids, protrusions, paper tears, etc. must first be filled and leveled with joint compound, then sanded smooth. Using a feathering spray technique Tuff-Hide should be blended into the surrounding coated surface.
For larger repaired areas, it may be necessary to re-spray the entire wall or ceiling surface. When re-spraying is not feasible, Sheetrock® Brand First Coat can be used over repaired areas using a high quality roller with a 1/8" to 1/4" nap and blended into the surrounding surface using a feathering technique.
