Coverage

1 gal. (3.8 liters) yields 231 cu. in. (3,785 cm3)
 

Coverage

Typical coverage is 150–175 sq.ft/gal. (3.7–4.3 sq. m/L) as healer/sealer.

As a primer, coverage is 200-300 sq.ft/gal. (18.6-27.9 sq. m/L)

Coverage varies with porosity and surface profile of substrate. Higher porosity concrete will reduce coverage. For crack healing, follow application instructions and allow to pond over cracks.
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

Proportion 1 part Component ‘B’ to 2 parts Component ‘A’ by volume into a clean pail. Mix thoroughly for 3 minutes with Sika Paddle on low-speed (400-600 rpm) drill until uniformly blended. Mix only that quantity that can be used within its pot life.
