PART 3 EXECUTION

3.1 SURFACE PREPARATION

Clean concrete and masonry surfaces to receive dampproofing of foreign matter and loose particles. Apply dampproofing to clean dry surfaces.

Moisture test in accordance with ASTM D4263. If test indicates moisture, allow a minimum of seven additional days after test completion for curing. If moisture still exists, redo test until substrate is dry.

3.1.1 Metal Surfaces

Ensure metal surfaces are dry and free of rust, scale, loose paint, oil, grease, dirt, frost and debris.

SECTION 07 11 13 Page 2

3.2 APPLICATION

Apply dampproofing after priming coat is dry, but prior to any deterioration of primed surface, and when ambient temperature is above 40 degrees F .

3.2.1 Surface Priming

Apply primer when ambient temperature is above 40 degrees F and at rate of approximately one gallon per 100 square feet , fully covering entire surface to be dampproofed.

3.2.2 Cold-Application Method

3.2.2.1 Emulsion-Based Asphalt

Do not perform emulsion-based asphalt dampproofing work in temperatures below 40 degrees F . Emulsions must have a smooth and uniform consistency at time of application. Apply dampproofing materials in accordance with manufacturer's published instructions to produce a smooth uniform dry film of not less than 12 mils thick without voids or defects. Recoat any dull or porous spots. Seal dampproofing materials tightly around pipes and other items projecting through dampproofing. Apply materials at rates as follows:

a. Primer: 1/2 gallon per 100 square feet , cold-applied.

b. Fibrated Dampproofing: 2 gallons per 100 square feet , cold-applied with spray, brush or trowel.

c. Non-fibrated Dampproofing: 2 gallons per 100 square feet , cold-applied with spray, brush or trowel.

3.3 PROTECTIVE COVERING

Protect dampproofed surfaces against which backfill will be placed with one layer of 15 pound saturated felt. Use asphalt-saturated felt where the dampproofing material is asphalt and use coal-tar-saturated felt where the dampproofing material is coal-tar pitch. Embed felts in the second coating of bitumen and lap edges and ends not less than one inch .
