- Designed for use on application down to 40°F (5°C)
- Water-based, low-tack primer specifically formulated to provide excellent adhesion
- Prime as needed all required surfaces
- Apply with a roller or brush
- Apply to a clear, dry, dust free, and frost free surface
- Low VOCs
Installation Application
VaproTak WB may be applied with roller or brush.
Apply VaproTak WB to a clean, dry, dust free, and frost free surface at a coverage rate of approximately 350-400 sq.ft. (32.52 -37.16 m²) per gallon on concrete.
Exterior gypsum sheathing board products will vary in texture, performance and porosity. The coverage rate for VaproTak WB will vary due to substrate texture and porosity. Specific testing for coverage is recommended.
The primer should be spread sufficiently to avoid areas of excess material.
Areas of excess material will lengthen the curing time on the application of the VaproTak WB.
Limitations
Limit the application of primer to what can be covered with VaproShield self-adhered roof and wall membranes in one working day.
Any areas not covered with membrane during the day must be recoated. Be sure to cover all open containers when not applying primer.
