Consumption

Coverage

Bonding Adhesive: 1 gal. covers approximately 80 ft2 on smooth surface.
Base Plate Grout: 1 gal. mixed with 1.5 parts oven-dried aggregate by loose volume yields approximately 420 in3 of grout.
Anchoring Grout: 1 gal. yields 231 in3 of grout.
Application steps

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

Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blast cleaning or other 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.
