PART 3 - EXECUTION
3.1 SURFACE PREPARATION
A.
Substrate must be clean, sound, and free of surface contaminants. Remove
dust, laitance, grease, oils, curing compounds, form release agents and all
foreign particles by mechanical means. Substrate shall be in accordance with
International Concrete Repair Institute (ICRI) Guideline No. 310.2 for
coatings.
3.2 MIXING AND APPLICATION
A.
Mixing: Premix each component. Proportion equal parts by volume of
Component A and Component B into a clean, dry mixing pail. Mix
thoroughly for at least 3 minutes with a Sika paddle on a low-speed (400-
600 rpm) drill. Mix only that quantity of material that can be used within its
pot life (35 minutes at 73°F). To minimize color difference, blend two
complete Component Bs together. Use only one of the blended Component
Bs to mix with Component A. After the first Component B has been used,
blend the second Component B with a new Component B and repeat the
above procedure for the entire application.
Placement Procedure: The epoxy resin coating shall be applied only to
approved, prepared surfaces with high-quality brushes, rollers, or spray
equipment. Coating shall be applied at ambient and substrate temperatures
between 50 and 90° F. Application thickness shall be between 4 and 7 mils
per coat. Subsequent coats shall be applied within 48 hours of the previous
