Substrate Preparation

• Remove grease, form oils and release agents.
• Shiny surfaces should be acid etched and the surface thoroughly rinsed clean to be free of acid deposits.
• Embedded steel, nails and reinforcing chair legs or spacing bars on or very close to the surface should be either removed or coated with epoxy to guard against corrosion, which could lead to rust stains.
• Check for the presence of release agents and bond breakers by simply splashing water onto the concrete substrate, if water beads on the surface then total removal of the release agent or bond breaker is required.
• The use of Dulux AcraTex Tiltwash is recommended for the removal of release agents or bond breakers.
• The repair of surface imperfections, cracks or flaws should be repaired as per the manufacturers specification.
• Structural control or expansion joints should be filled with a backing rod and flexible paintable polyurethane mastic.

Texture and Finish

• All Dulux AcraTex texture coatings should be overcoated with Dulux AcraTex Acrashield Advance, which can be tinted to any colour from the Dulux colour range.
• 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.
