- Mix 3 parts dry putty powder with 1 part water in a disposable container, using a putty knife to stir it until the putty forms a dough.
- Add dry paint pigment, powdered tempera paint or dry earth powders such as sienna to the water putty to achieve a color match with your countertop. Add only the amount of color necessary to achieve the desired color; adding too much pigment will lengthen the putty's drying time.
- Scoop a quarter-sized clump of putty onto the putty knife. Press the putty into the hole on the kitchen countertop. Continue filling the hole with putty. Allow the putty to dry for about 20 minutes. Don't scrape or smooth the wet or drying putty. Clean around the repair site with a damp cloth, if necessary.
- Scrape away any excess putty with the edge of your putty knife. Allow the putty to dry for about 8 hours. Steel putty knives featuring a knife blade that is also part of the handle construction are the most reliable.
- Sand the dried putty filling with medium-grit sandpaper until smooth and level with the kitchen countertop. If you premixed your color, your hole is repaired.
- Paint the filled hole with enamel paint, using a small paintbrush, if you haven't premixed the color. Allow the paint to dry before using your countertop.
