This primer is unlike other quartz primers as it serves as a primer and permanent binder in one; however, is based on entirely different binding protocols than our interior quartz primer system. This product contains special polymeric resins that will help to seal and consolidate your stucco brown coat, or other cementitious finishes. We also incorporate a fine marble powder and silica grain to act as a tooth that helps create an easy surface to trowel on and accepts and holds the plaster grains in place. Quartz primer is a low odor, low VOC PVA based primer specifically designed as a preliminary binder coat before lime and cement based plasters only for exteriors or heavy texture coats on interior walls. It can be applied on stucco brown coat, glass stucco, painted surfaces, acrylic stucco, brick, stone etc. For use on horizontal wall surfaces on exteriors where a permanent bond is required to your substrate. This product if applied as recommended should produce a permanent mechanical bond to your substrate and your base coat of plaster.
Very dry or old concrete-or any surface that is extremely porous-should be dampened prior to application of the diluted primer coat to reduce excessive absorption. Surface applied quartz primers are often applied over concrete masonry to equalize suction and prevent joints from shadowing through. The lime and or cement in the plaster will activate the primer and the two will form a bond that is permanent.
