Walnut Wood Patch. WOODWISE wood fillers were developed for water and solvent based stains and finishes. These environmentally friendly wood fillers contain no harsh solvents, and do an outstanding job of filling cracks, nail holes, gouges and broken edges. They take stains at rates similar to wood, and receive natural, light, dark, white and gray stains better than other fillers. WOODWISE is easier to sand, and finishing goes quickly because edger papers don't clog or become dull, lasting 2-3 times longer than with other fillers. WOODWISE bonds tightly, fills smoothly, dries evenly and hard, and cleans up easily with water. WOODWISE Wood Patch & Full-Trowel Filler are available in 16 different colors.
