Limitations and Warranty

  • A positive slope of 1/2” in 12” must be in place prior to application.
  • Kwikply cannot be used with coal tar mastic but can be applied over coal tar roofs with appropriate separation. Phased construction is not approved.
  • Kwikply should only be applied when temperatures are 45°F and rising.
  • Kwikply should not be applied directly over insulation. The use of HyGlass recover board is recommended. HyGlass must be primed with a quick-drying water-based primer such as HyBond, or HyPrime primer. Fastening must be completed following Hyload specifications or the insulation manufacturer’s specification if more restrictive. When Factory Mutual standards are required, refer to the FM Approval Guide and latest supplement.
