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.
