I came across an article recently explaining how to refinish your wood floor without sanding it first. I repeat, WITHOUT SANDING! They recommended a kit called “The Varathane Renewal Floor Refinishing Kit.” This kit works best on floors that have no more than normal wear (no deep scratches or areas where the finish is completely worn away or flaking off) and no wax finish.
How To Refinish Your Wood Floor Without Sanding
Clean the floor thoroughly by removing furniture, vacuuming, and wiping off with a damp cloth. Make sure your floor only has minimal wear and tear to it; if it does, consider hiring a professional to take care of the problem.
Instead of sanding, you will be using a liquid etcher to rough up the surface of your floor, allowing the new coat of finish to stick. It is recommended that you put the paint tray (filled with etcher) into a shallow cardboard box lined with a plastic bag to catch spills. Make sure to scrub the floor firmly. Wipe off the etcher as you go along because it can damage the floor if left on too long.
Once the floor has dried for about 30 minutes, re-mop the floor with a solution of 2 tbsp. dishwashing liquid and a gallon of warm water. Wear shoe covers to keep the floor clean. Wipe up the wetness. Fix scratches with matching stain and floor finish from the kit.
Apply the finisher with help from a buddy. One of you will apply the finish with a paint pad while the other follows close behind with the applicator pad. The helper can fix drips and puddles with a paintbrush as you go along. Make sure not to paint yourself into a corner! Once finished, allow about 3 hours for the first coat to dry, then apply a second coat. I can’t wait to try this! This will make a very dreaded task a whole lot easier:)
