Hold a hot patch knife and wax directly over the scratch. Choose a wax stick that most closely matches the color of your wood table. Allow the wax to drip gently onto the scratch until the wax forms a slightly rounded mound.
Press a spatula onto the melted wax to fill the scratch. Rub the area gently with a clean rag. Scrape the area level with the spatula.
Allow the area to dry completely. Brush on shellac to harden the area. If necessary, varnish the repaired patch if your table has a varnish finish.
Choose a wood putty color that most closely matches your tabletop finish. Dust the area to be filled.
Apply wood putty with a small putty stick. For very small scratches, use your fingertip to apply the putty. Rub the putty into the scratch until it is smooth.
Wipe away excess putty with a clean, dry rag. Adjust the color if necessary with a commercial stain marker. Varnish the repaired patch if your table has a varnish finish.
