Application Steps

SUBSTRATE QUALITY

Surface must be clean and sound. It may be dry or damp, but free of standing water.

SUBSTRATE PREPARATION

Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials.
Preparation Work:
Concrete - sandblast or use other approved mechanical means
Steel - Sandblast to white metal finish

MIXING

Pre-mix each component thoroughly. Place 1 part by volume of component A and 1 part by volume of component B into a clean pail. Mix thoroughly for 3 minutes with low-speed drill (400-600 rpm) until uniformly blended. Mix only the quantity that can be used within its pot life. To prepare an epoxy mortar, slowly add 1 part by loose volume of an oven-dried aggregate to 1 part of the mixed Sika® Epoxy 7300 and mix until uniform in consistency and color.
