| USES Karnak
#100 Non-Fibered Emulsion Dampproofing is a vapor retarder used
as a protective coating against dampness on the exterior face of
interior walls in cavity wall construction and exterior surfaces
of concrete, metal and wood above or below grade. It may also be
applied to interior surfaces in the absence of hydrostatic pressure.
The emulsion may be utilized as an adhesive for polystyrene insulation
prior to backfilling.
SPECIFICATION
- ASTM D-1187 Type II
- ASTM D-1227 Type III, Class 1
- SS-R-1781
- MIL-R-3472A
SURFACE PREPARATION Surface
should be free of oil, grease, dirt laitance and adhesion-inhibiting
materials. Dry surfaces should be dampened with water before application
of the coating. Repair all cracks and holes with Karnak #920AF Fibered
Emulsion Mastic or Karnak #925 Fibered Emulsion Mastic Trowel Grade
Emulsion and Karnak #31 Fiber-Glass Membrane or Karnak #34 Asphalt
Saturated Cotton Fabric before applying the surface coating.
APPLICATION Karnak
#100 Non-Fibered Emulsion Dampproofing is easily applied by brush,
roller or spray equipment.Apply Karnak #100 Non-Fibered Emulsion
Dampproof-ing in one coat. If applying two coats, allow the first
coat to dry. Coating should be continuous and free of pinholes or
holidays. Cover all slots, joints and grooves and apply into all
chases and corners.
- Above-grade dampproofing (interior and exterior): 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).
- 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.)
- 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.
- 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.
BRUSH APPLICATION:
Apply with a wide fiber brush. Apply at the rate
of 2 to 4 gallons per 100 sq. ft..
SPRAY APPLICATION:
Utilize a standard heavy duty spray pump using heavy duty guns
and nozzles. Apply at the rate of 2 to 4 gallons per 100 sq. ft..
Equipment manufacturer should be consulted for more complete information.
COVERAGE RATE Apply
at 2 to 4 gallons per 100 square feet. Spray application should
be at the same rate.
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.
