Varathane Diamond Wood Finish is a water-based polyurethane manufactured by the Rust-Oleum Corporation. It is available in spray cans as well as in half-pint, quart and gallon cans. According to the finish's online product brochure, it produces a clear surface that resists yellowing better than comparable oil-based finishes manufactured by the same company. It is odour-free and easier to clean up than oil-based finishes. Varathane Diamond Wood Finish is readily applied by spraying or painting with a paintbrush. You will get the best results if you first take steps to properly prepare the surface.

  1. 1

    Wash the surface to be coated if it already has a finish. Mix detergent with hot water in a bucket and use the solution to wash off dirt, grime and old wax.

  2. 2

    De-gloss the existing finish by sanding it lightly by hand with 150-grit sandpaper. If the surface is unfinished, sand it with 120-grit sandpaper, wipe off the sanding dust with a rag, and sand it again with 150-grit sandpaper. Either sand by hand or use an orbital sander. If you sand by hand, always move the paper with the grain of the wood.

  3. 3

    Apply the Varathane Diamond Wood Finish by spraying from a spray can or painting with a paintbrush. If you spray, hold the tip of the can about 6 inches from the surface and depress the nozzle. Keep the can moving in a lateral or vertical direction as long as the nozzle is depressed. Move in a steady motion from one edge of the surface to the other and return, overlapping by about one half of the spray pattern. Leave a light, wet coat without drips.

  4. 4

    Paint the product with a paintbrush that has synthetic bristles. Move the brush with the grain of the wood, being careful not to leave voids, or areas without finish.

  5. 5

    Let the first coat dry for two hours. Sand the surface lightly, then apply a second coat. Let it dry for two hours, then apply a third coat. The Rust-Oleum Corporation recommends a minimum of three coats for best results. The surface is ready for handling after the final coat has dried for two hours.

Tips and warnings

  • If you have to wait longer than 24 hours between the second and third coats, lightly sand the surface before applying the third coat.
  • Varathane Diamond Wood Finish is nontoxic; you can ingest up to an ounce without significant ill effects. If you ingest more than that, do not induce vomiting; instead, drink water and seek medical attention.
  • If you get Varathane Diamond Wood Finish in your eyes, flush them with water for 15 minutes and seek medical attention. Do not rub your eyes.
