PART 3 - EXECUTION

3.1 PROJECT CONDITIONS

A. Maintain temperature of materials above 21oC (70 degrees F), for 48 hours before installation.

B. Maintain temperature of rooms where work occurs, between 21oC and 32oC

(70oF and 90oF) for at least 48 hours, before, during, and 24 hours after installation. Maintain temperature at least 21oC (70 degrees F) thereafter.

09 67 23 - 4

C. Do not install materials until building is permanently enclosed and wet construction is complete, dry, and cured.

D. Concrete substrate cured and not less than 30 days old.

E. Area free of other trades during and for a period of 24 hours after installation.

3.2 INSTALLATION REQUIREMENTS

A. The respective manufacturer's instructions for application and installation will be considered for use when approved by the RE/COR.

B. Submit proposed installation deviation from this specification to the

RE/COR indicating the differences in the method of installation.

3.3 PREPARATION

A. Prepare surface in accordance with manufacturer's instructions.

B. Mechanically remove bond inhibiting materials and loose or laitance materials to ensure bond.

C. Moisture Testing: Perform moisture and pH test as recommended by the flooring and adhesive manufacturers. Perform test locations starting on the deepest part of the concrete structure. Proceed with installation only after concrete substrates meet or exceed the manufacturer’s requirements. In the absence of specific guidance from the flooring or adhesive manufacturer the following requirements are to be met:

1. Perform moisture vapor emission tests in accordance with ASTM F1869.

Proceed with installation only after substrates have a maximum moisture-vapor-emission rate of 1.36 kg of water/92.9 sq. m (3lb of water/1000 sq. ft.) in 24 hours.

2. Perform concrete internal relative humidity testing using situ probes in accordance with ASTM F2170. Proceed with installation only after concrete reaches maximum 75 percent relative humidity level measurement.

2. Grind, sand, or cut away protrusions.

3.4 APPLICATION

A. Mix and apply each component of resinous flooring system in compliance with manufacturer's specifications to produce a uniform monolithic flooring surface of 5 mm (3/16 inch) minimum thickness.
