ZAR Wood Patch is a latex compound that both contractors and savvy do-it-yourselfers rely on to fill nail holes, and repair cracks, gouges, broken corners, and chipped edges on wood surfaces. It's excellent for a variety of uses because it only shrinks a little, and can be nailed, sawed, sanded, or drilled. ZAR Wood Patch can be used indoors or outdoors, and accepts paint, varnish, shellac, polyurethanes, and stains. In fact, it actually accepts stain more readily than conventional wood patching compounds.
