CCW AWP: Latex-Based Contact Adhesive
CCW AWP is a single-component latex-based contact adhesive. CCW AWP is an accessory product to the CCW waterproofing membranes and is designed to set the dust on concrete to promote adhesion of the CCW waterproofing membrane to the substrate. Questions? Contact Us.
CCW AWP can be roller- or spray-applied at a coverage rate of 400 ft2(37.2 m²) per gallon (3.8 liters). Several types of sprayers- Airless, Air Assist, Hudson- may be used. (CCW AWP may also be applied using a roller. However, caution must be taken not to apply excess contact adhesive which could cause longer drying times.) Normal drying time will be approximately 30 minutes depending on weather conditions. Upon curing, CCW AWP will not transfer when touched. Exposed surfaces must be reprimed as they may collect dust and other contaminants causing adhesion problems. CCW AWP should be applied at temperatures above 40°F (4.4°C). Apply to surface the same day of application of waterproofing membrane. All fluid-applied product application rates are based on theoretical
coverage relative to the percentage of solids in the material. These are minimum application rates to achieve the required dry film thickness for the system and do not account for substrate condition or porosity.
A thicker application of the product may be necessary to achieve the required dry film thickness for system relative to the substrate. When installing CCW sheet membranes and sheet flashings over gypsheathing with glass-mat facers, coverage rates for contact adhesives and primers will depend on the porosity and texture of the sheathing and will vary substantially by gypsum-sheathing brand and manufacturer. To achieve consistent contact adhesive and/or primer coverage with adequate tack, it may be necessary to decrease the coverage rate (i.e. Increase the amount applied) of the contact adhesive and/or primer and/or the application of multiple coats. CCW Contact adhesives and primers shall be allowed to dry completely (lower temperatures will extend drying time) before additional coats are applied or membranes installed. Caution should be taken as contact adhesives and/or primers applied to gyp-sheathings with glass-mat facers will take longer to dry than other substrates. Multiple adhesion tests should be performed randomly to verify proper application of primer and ensure a successful application.
