With this revolutionary fabric patch, you simply cut, wet and press the Wet & Set® patch over the damaged area. It dries hard in minutes, forming a polymer adhesion that will never peel or delaminate. Stains, holes, cracks and crumbling damage disappear within seconds, replaced by a hard, permanent patch that's ready for a finish coat within 15 to 30 mins. Can be used on drywall, plaster, stucco and even wood.
