Scope of Use
Substrate Preparation
- Glazing on glazed bricks should be ground or scabbled to improve adhesion of the render system.
- Remove any powdery layers, laitance or efflorescence by detergent cleaning, wire brushing or water blasting.
- Brickwork is often raked, so rendering requires much more material than face laid brickwork.
- With both brick and concrete blocks the surface should be examined to determine if it has been laid to specification (flush jointed or face laid) and that the surface variation is within acceptable tolerances.
- When applying a render coat, the degree to which the render coat camouflages flush walls depends on how well the substrate has been constructed or laid.
Texture and Finish
- Two coats of AcraShield Advance should be applied over the Dulux RenderWall Float Finish using a 12-16mm nap roller.
- If a dark colour is chosen over a Acrylic texture two coats of AcraShield Advance is recommended to attain good coverage.
- All texture and colour samples must be signed by the architect or owner prior to application.
