SUBSTRATE QUALITY
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.
SUBSTRATE PREPARATION
Substrate must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials.
Concrete: Sandblast or use other approved mechanical methods.
Steel: Sandblast to white-metal finish (SP-10).
MIXING
Pre-stir each component then proportion equal parts by volume of component A and component B into a clean pail. Mix thoroughly for three (3) minutes with paddle on low-speed drill (300 - 450 rpm) until blend is a uniform colour. Mix only that quantity that can be applied within its pot life.
CLEAN UP
Collect with absorbent material. Dispose of in accordance with local disposal regulations. Uncured material can be removed with Sika® Epoxy Cleaner. Cured product can only be removed mechanically.
