Before applying paint, clean the surface with an all-purpose cleaner to ensure removal of all soap scum, dirt, mold, mildew and grime. Put on a respirator, and use 120-grit sandpaper or steel wool to completely remove any glossy finish. The epoxy paint adheres to a rough surface much better than a smooth one, so take plenty of time to ensure adequate preparation of the surface. After sanding, clean the surface with trisodium phosphate, rinse well and let dry.

Tape plastic around any areas you do not want to paint, including drains and fixtures. Make sure the area has adequate ventilation, and apply the epoxy paint with a spray gun in smooth, even layers. Allow the paint to dry, and go over each coat with fine-grit sandpaper to smooth the surface and create an even shine. Thoroughly clean the surface, and allow to dry before spraying the next coat.

Allow the paint to dry for at least 24 hours or according to the manufacturer’s instructions before using the shower. Attempting to use the shower before the paint has fully cured can result in a wrinkled surface.
