CGC Medium Texture Finish For Interior Ceilings is a powder product formulated with polystyrene aggregate to provide a medium texture finish. Mixed with water on the job site it provides good pumpability for fast, easy spray application. Bonds to new or old concrete, gypsum panels, plaster, wood and even metal pipe when primed. Masks minor surface defects and has superior resistance to fissure cracking in recommended thicknesses. Dries to a crisp white finish that usually is left unpainted but may be over-painted if desired.
