ROCKCOTE Polymer Renders are pre-mixed, 100% acrylic based renders designed to be flexible and lightweight.
ROCKCOTE’s Polymer Renders are especially suitable for application over fibre cement (blueboard) and painted substrates where tolerance to movement and good adhesion must be considered.
Each render is composed of specially selected graded quartz sand with a pure acrylic binder system and other proprietary additives. ROCKCOTE Polymer Renders are highly crack-resistant and can be used in interior and exterior applications.
- Suitable for application over properly prepared substrates such as brick, block, ROCKCOTE render, concrete, fibre cement sheeting (blueboard), A.A.C. panels/blocks and plasterboard.
- Must be overcoated with a minimum ROCKCOTE Coloured Render or ROCKCOTE Armour membrane paint.
Polymer Render Grey: a high-build polymer render which can provide a build out coat of up to 4mm. Can be trowelled then floated/sponged straight away at 1-2mm. High in volume solids, displays minimal shrinkage and has excellent crack-bridging properties.
Polymer Render Off White: ROCKCOTE’s original, premium polymer render that is easy to apply and finish. Best applied in coats of 1-1.5mm.
Polymer Render Fine: comprised of finer sands that can create a finer finish and aesthetic.
Polymer Render Coarse: the only difference is the composition of a larger sand.
