Tough, flexible, rubberized sealant for temporary or permanent applications on a variety of surfaces. Fast drying elastic barrier seals out moisture, resists rust, road salts, alkali and acids, and allows maximum build-up without sagging. Can be topcoated after curing without bleedthrough, resists temperature extremes, and deadens sound. Use on skylights, flashings, air vents, gutters, antenna installations, small cracks, or holes in driveways, and tree and shrub pruning. Use in well-ventilated areas and keep away from heat, sparks, and flames. Dries to touch in 10 min and to handle in 4 to 6 hr. Low luster sheen. Black.
