Easy to use aerosol spray shoots a thick liquid that seeps into cracks and holes. Dries to a watertight, flexible, rubberized coating that seals and protects from moisture penetration. It will not sag or drip in the summer heat, will not crack or peel in the winter cold. Stops vibrations, deadens noise and protects the surface from corrosion. Can be applied on wet or dry surfaces and once dry can be painted any color. Ideal for gutters, vents, sky lights, foundations, lawn and garden projects, arts and crafts and more.
