Surface Preparation

Bare Masonry Surfaces:

Allow all surfaces to dry completely prior to painting. Remove dirt, dust, grease, and any other contaminants. Smoothen the surface using suitable sand paper or sandstone. Dust off thoroughly. Avoid painting when the moisture content and alkalinity of the walls is still high. (Recommended painting specification requires the moisture content of the walls to be below 16% and alkalinity of the walls to be below pH9.)

Previously Painted Surfaces:

Remove unstable paint film, loose chalk by rubbing down using abrasive paper or wire brush and dust off thoroughly. Use Griplac Subtle Wall Filling to repair cracks if necessary. Masonry work is recommended to fill large cracks and holes. Allow to dry completely before applying Griplac Robust Acrylic Primer.
