Application steps

SUBSTRATE PREPARATION

Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes and any other contaminants.
Preparation Work: Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blast cleaning or equivalent mechanical means.
Steel - Should be cleaned and prepared thoroughly by blast cleaning or other equivalent mechanical means.

MIXING

Pre-mix each component. Proportion equal parts by volume of Component ‘A’ and Component ‘B’ into clean pail. Mix thoroughly for 3 minutes with Sika paddle on low-speed (400–600 rpm) drill until blend is a uniform color. Mix only that quantity that can be applied within its pot life.
