Yes. A single application of Sheetrock® Brand Tuff-Hide™ at 15-20 mils wet film thickness can be used in lieu of the skim coat and prime coat steps in a Level 5 finish. It is critical however that a Level 4 finish is completed prior to the application of the Sheetrock® Brand Tuff-Hide™. While the Sheetrock® Brand Tuff-Hide™ product will fill and hide many minor surface imperfections, it is not intended to achieve a Level 5 finish from a surface prepared to a Level 3 or below. It is also critical that the product be applied to a minimum 15 mils WFT in order to achieve the desired results. A Wet Film Thickness gauge should be used throughout the application process to ensure proper thickness.
