Not recommended for building materials that bleed oils, plasticizers, or solvents-materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes. Not recommended for use in totally confined spaces as the sealant requires atmospheric moisture for cure. Not recommended for continuous water immersion applications. Not recommended for use on frost-laden or wet surfaces. Not recommended for places where painting of the sealant is required, as the paint film may crack and peel. Do not apply at temperatures below 4℃ or above 40℃.
