Cats love to scratch, and they don’t always differentiate between their scratching post, your favorite armchair, wall molding and a windowsill. If your kitty has created significant damage to your sills, simple repair techniques can get them back into tip-top shape. Consider an anti-scratch plan to protect against future damage after repairs are made.
Things You'll Need
- Drop cloth
- Sander or wood stripper
- Degreasing agent
- Stainable wood filler
- Putty knife
- Wood stain or paint
Position a drop cloth over furniture or flooring under the windowsill that could be damaged by flying sawdust and wood stain; otherwise remove the furnishings.
Clean the windowsill using a degreasing cleaning agent and allow it to dry. Sand the cat-scratched portions of the windowsill, sanding in the direction of the wood's grain. If a small area is damaged, you should be able to touch up a single section. If the entire windowsill is damaged, you may opt to sand away the paint or varnish across the entire surface to create a uniform finish. Use a sander or a wood stripper for this process.
Fill in pits or grooves with wood filler as necessary, using a putty knife to apply it. Follow directions on the manufacturer’s label for how long to allow the material to cure. Once it's dry, sand the surface again until you get a smooth and seamless finish.
Stain or paint the windowsill as desired. Allow the paint or stain to dry completely, and seal with a polyurethane topcoat.
