Preparation & Application
Surface should be free of oil, grease, dirt laitance and adhesion-inhibiting materials. Dry surfaces may be dampened with water before application of the coating. Repair all cracks and holes with KARNAK #20 Fibered Emulsion Mastic and KARNAK 31 Fiber-Glass Membrane or KARNAK 34 Asphalt Saturated Cotton Fabric before applying the surface coating.
Apply with a wide fiber brush. Apply at the rate of 2 to 3 gallons per 100 sq. ft.

A. Above-grade dampproofing (interior and exterior cavity walls:
Apply one coat of KARNAK 100 Non- Fibered Emulsion Dampproofing at a rate of 2 to 3 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).
B. Below-grade dampproofing (interior, exterior and cavity walls):
Apply one coat of KARNAK 100 Non-Fibered Emulsion Dampproofing at a rate of 2 to 3 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.)
C. Fabric re-enforced dampproofing:
Apply one coat of KARNAK 100 Non-Fibered Emulsion Dampproofing at a rate of 2 to 3 gallons per 100 sq.ft. Apply KARNAK 31 Fiber Glass Membrane or KARNAK 34 Asphalt Saturated 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.
D. Polystyrene insulation adhesive:
KARNAK 100 Non-Fibered Emulsion Dampproofing is a water-based asphalt emulsion that is 100% compatible with polystyrene insulation or protection board. As an adhesive, KARNAK 100 Non-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.
Caution/Care of Tools
Do not apply when rain is imminent. Protect from freezing. Coating must be dried before exposure to water. Store in a heated room and keep container covered when not in use. Do not thin. Avoid prolonged contact with skin. Dispose of in an environmentally safe manner.
CARE OF TOOLS:
Tools and other equipment should be cleaned with water immediately after use. Dried coating may be cleaned with mineral spirits. Take necessary precautions when handling combustible material.
