DISSCO 721 Non-Fibered Emulsion Dampproofing is a cationic slow setting emulsified bitumen designed for use as a below grade foundation dampproofing compound for dampproofing applications where it is desired to prevent dampness or moisture that may be present in below-grade applications from penetrating the foundation, thus preventing the damp feeling common to most basements. However, where a high water content is present the coating to be used should be upgraded to a true waterproofing compound. DISSCO 721 is suitable for use on almost any material such as concrete, masonry block, styrofoam block, wood, steel, plastic. DISSCO 721 is environmentally friendly containing no solvents. Ready to use. No mixing or thinning necessary. No heating required.
DISSCO 721 is ready to use directly from the container. Surface to be coated must be clean and dry, free of any material which prevents proper adhesion. DISSCO 721 can be applied by roller, brush or spray with adequate airless equipment. It is recommended that masonry block be parged (cement grouted) prior to application.
For a one coat application, it is recommended that the DISSCO 721 be applied at a coverage rate of 1.25 to 2.0 gallons per 100 square feet of surface area with a dry film thickness of approximately 15 mills. For a two coat application, each coat should be applied at a coverage rate of 1.0 to 1.5 gallons per 100 square feet with a two coat dry film thickness of approximately 20 mills. The first coat should be allowed to cure for at least 4 hours before the second coat is applied. Do not apply when rain is imminent or when surface to be coated or ambient air temperature is below 40ºF (4ºC).
Cure time will vary depending on weather conditions. Product will appear brown in color after applied and will turn black in color when cured.
