1.	Concrete surfaces shall be in sound condition and properly prepared prior to flooring system installation.
2.	Defects in existing work that affect proper execution of coating work.
3.	Deviations beyond allowable tolerances for the concrete slab work.
B.	Do not begin installation until substrates have been properly prepared.
C.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Prepare substrate to receive coating in accordance with manufacturer's recommendations.
B.	Substrate shall be free of dirt, waxes, curing agents, and other foreign materials.
C.	Objectionable substrate irregularities that will transmit through coating system shall be removed.
D.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
E.	Acceptable Substrates:
1.	Level tolerance: Concrete sub-floor shall be level with a maximum variation from level of 1/4 inch (6 mm) in 10 feet (3048 mm). Any irregularity of the surface requiring patching and/or leveling shall be done using material approved by the manufacturer.
2.	Concrete floor shall have a steel trowel finish.
3.	Concrete shall be cured a minimum of 28 days. No curing agents shall be used in areas to receive coating.
4.	Concrete slab shall have an efficient moisture barrier of minimum 10 mils (.2540 mm) placed directly under the concrete slab. Do not use vapor barrier manufactured with recycled content. Testing shall be done to verify that the moisture vapor emission rate of the slab does not exceed that as recommended by the manufacturer at time of installation of the epoxy coating flooring. Moisture vapor emission and moisture content testing shall conform with the requirements of ASTM F 1869 (Calcium Chloride Test) and ASTM F 2170 (Relative Humidity Probe Test). If test results show excessive levels of moisture content or vapor emission rate above that recommended by the manufacturer, apply manufacturer's recommended moisture vapor emission control material.

Apply Key #580 Flexible Epoxy across the crack a minimum width of 24 inches (610 mm) at a spread rate of 50 square feet (4.6 square meters) per gallon to achieve 25-30 mils (.6350-.7620 mm) dry over the crack and allow to cure. Apply Key #502 Primer to cured membrane. Imbed fiberglass mesh into wet primer and saturate with additional Key #502 Primer.
3.	Apply Key #580 Flexible Epoxy over entire floor surface as a crack isolation membrane if cracks are numerous.
