ROCKCOTE Grey Polymer High Build Render is a flexible acrylic base coat render mainly composed of specially selected graded quartz sand with a pure acrylic binder system and other proprietary additives. ROCKCOTE Grey Polymer High Build Render is premixed, and is especially suitable for fibre cement (including Blueboard) and painted substrates where tolerance to movement and good adhesion must be considered. ROCKCOTE Grey Polymer High Build Render is high in volume solids, and displays minimal shrinkage.
Must be overcoated with ROCKCOTE Coloured Render, texture, or ROCKCOTE Armour Paint.
