How to Seal a Crack on Twin Doors

Cracks that appear on twin doors make the doors seem old and weathered, and can cause your rooms to look unsightly. Replacing twin doors with new doors may not be in your budget, especially when you buy the doors from a home decorating shop. Save money by repairing and sealing cracks on the twin doors using inexpensive materials found at any home improvement or hardware store. This enables you to create tidier and cleaner-looking doors without spending a fortune in the process.

Medium-grit sandpaper
3-inch flat paintbrush
Wood putty
Triangular trowel
Latex paint or clear sealant

Instructions

- 1
  Sand the edges of the cracks on both doors using medium-grit sandpaper. Move the sandpaper in small, circular motions over the cracks, which will remove splintering, roughness and sharpness.
- 2
  Brush the sawdust out of the cracks and off of the doors using a paintbrush.
- 3
  Spread wood putty over the cracks using a triangular trowel, pressing and smoothing the putty into the cracks.
- 4
  Run the tip of a toothpick across the soft wood putty to copy the grain of the wood on each of the twin doors. Allow the putty to dry for six hours.
- 5
  Paint the twin doors using latex paint or clear sealant using a 3-inch flat paintbrush. Allow the paint or sealant to dry for 12 to 18 hours.
