SURFACE PREPARATION:
Surface should be free of oil, grease, dirt, laitance and loose material. Dry surfaces may be dampened with water before application. Repair all cracks and holes with 220 Fibered Emulsion (Dampproofing) and 31 Fiberglass Membrane or 34 Asphalt Saturated Cotton Fabric, before applying the surface coating.
APPLICATION:
220 Fibered Emulsion (Dampproofing) is easily applied by brush, roller or spray equipment. Apply 220 Fibered Emulsion (Dampproofing) in one coat. If applying two coats, allow the first coat to dry. Coating should be continuous and free of pinholes and holidays. Cover all slots, joints and grooves and apply into all chases and corners.
BRUSH APPLICATION:
Apply with a wide fiber brush at the rate of 4 to 6 gallons per 100 sq. ft. (64-96 wet mils).
SPRAY APPLICATION:
Utilize a standard heavy-duty spray pump using heavy duty guns and nozzles. Apply at the rate of 4 to 6 gallons per 100 sq. ft. Equipment manufacturer should be consulted for more complete information.
Above-grade dampproofing (interior and exterior cavity walls):
Apply one coat of 220 Fibered Emulsion (Dampproofing) at a rate of 4 to 6 gallons per 100 sq. ft. If applying two coats, each coat should be 2 to 3 gallons per 100 sq. ft. (First coat must be allowed to dry prior to the application of the second coat).
Below-grade dampproofing (interior, exterior and cavity walls):
Apply one coat of 220 Fibered Emulsion (Dampproofing) at a rate of 4 to 6 gallons per 100 sq. ft. If applying two coats, each coat should be 2 to 3 gallons per 100 sq. ft. (First coat must be allowed to dry prior to the application of the second coat.)
Fabric reinforced dampproofing:
Apply one coat of 220 Fibered Emulsion (Dampproofing) at a rate of 2 to 3 gallons per 100 sq. ft. Apply 31 Fiber Glass Membrane or 34 Asphalt Cotton Fabric over the wet coating, overlapping all edges. Smooth out all wrinkles, making sure there is no trapped air underneath the fabric. Proceed with second coat at a rate of 2 to 3 gallons per 100 sq. ft.
Polystyrene insulation adhesive:
220 Fibered Emulsion (Dampproofing) is a water-based asphalt emulsion that is 100% compatible with polystyrene insulation or protection board. As an adhesive, 220 Fibered Emulsion (Dampproofing) should be applied in 4” diameter dabs directly to the insulation and immediately pressed into place.
Note:
When more than two courses are required, wall ties may be necessary. Allow the film to cure for a minimum of 24 to 48 hours prior to backfilling. Care should be taken during backfilling not to puncture or damage the coating. A protection board is highly recommended, and backfilling should take place within 7 days.
COVERAGE RATE:
Apply at 4 to 6 gallons per 100 sq. ft. Spray application should be at the same rate
