Rubberized Wet Patch resists sags and spreads easily in cold conditions.

For exterior use only

  • Excellent adhesion for immediate all-weather repairs

  • Highly flexible to prevent cracking
  • Sag resistant, suitable for vertical repairs

APPLICATION Apply only when air, material, and surface temperatures are between 40-120ºF (4-49ºC) and the relative humidity is below 85%. Apply with a trowel directly over a cleaned substrate at a rate of 12 square feet per gallon or approximately ⅛” thick. When making roof repairs or striping over the top of flashing laps, perform a 3-course repair consisting of one application of Rubberized Wet Patch followed by an embedded strip of Rust-Oleum Universal Patching Fabric or other mesh, followed by a final application of Rubberized Wet Patch.

COVERAGE Each gallon will cover approximately 12 square feet when applied at ⅛" thick. Actual coverage will vary depending upon ambient temperature and surface conditions.

DRY & RECOAT TIMES Dry and recoat times are based on 70ºF and 50% relative humidity. Product will reach full cure in 24 hours. Environmental or site specific conditions may lead to a variation in dry time.

CLEAN-UP Wash tools and equipment with mineral spirits. Wipe up spills before they dry. Properly dispose of all soiled rags and containers.

LIMITATIONS Not for use on coal tar membranes. Repairs made to wet surfaces should be considered temporary as trapped moisture may expand when heated by the sun causing blisters and potentially new leaks. For permanent repairs, open up the area and allow it to dry thoroughly.
