Durham's is the go-to product for homeowners and handypersons for making repairs to wood, drywall, patching plastic, tile, and many more uses. Durham's stays put and does not shrink. It can be sawed, chisled, sanded, polished and colored. Use Durham's for lasting repairs. Durham's Rock Hard Water Putty fills voids like holes, cracks, and the like. Just fill the void completely until the putty bounces back. After the putty has set up, remove the excess. It adheres to the sides of the hole for permanence. Use Durham's to patch cracks and holes in walls, repair furniture, tighten loose wood joints, fill holes in wood so dowels and/or screws can be reset, fill edges and imperfections in plywood, and repair all kinds of antiques.
