materials for a period of five (5) years, beginning with date of substantial
completion of the project.

PART 2 - PRODUCTS

2.1 EPOXY RESIN COATING

A. Sikagard 62, as manufactured by Sika Corporation. No substitutions will be
allowed.

B. Granules for slip-resistance shall be supplied by the manufacturer of the
specified product and shall be able to be mixed into the coating and shall
not settle during application. Granules shall be used for the floor coating of
the sump riser building.

C. Color - Grey.

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

coat. Care is to be taken on vertical and overhead surfaces to avoid sags or
runs. If this occurs, it must be sanded out and the area re-coated. If coating
of horizontal surfaces that will receive traffic is specified, a slip-resistant
aggregate, Sikagard 62 Granules, shall be incorporated into the mixed epoxy
resin coating at % lb/gallon.

When applying the coating, if possible never stop the application until the
entire surface has been coated. If possible always discontinue at an edge,
corner, or joint. Never let a previously coated film dry. Always coat into wet
film. Always apply the coating at a 45° angle to an edge, corner, or joint.

Adhere to all limitations and cautions for the epoxy resin as stated in the
manufacturers printed literature.

3.3. CLEANING

A. The uncured epoxy resin coating can be cleaned from tools with an approved
solvent. The cured epoxy resin coating can only be removed mechanically.

B. Leave finished work and work area in a neat, clean condition without evidence
of spillovers onto adjacent areas.
