Aesthetically appealing banisters are essential to clean and comfortable homes. Banisters are often one of the first objects a guest will see when entering your home. Fixing a wood banister chewed by a dog rids the railing of unsightly marks and prevents injury to people or animals that may bump into or grab the object in disrepair. Applying wood putty to fill in the chew marks is a cost saving technique, in lieu of replacing the banister outright.
Remove any loose shards of wood from the damaged area with a wood chisel. Wipe the area clean with a cotton cloth.
Coat the chewed banister with water-based wood putty or grain filler. Spread the mixture evenly over damaged areas with a putty knife. Allow the putty or filler at least one hour to fully dry. Follow all prefabricated product instructions for mixing and application.
Rub the putty smooth with 120 grit sand paper. Open a nearby window or turn on a box fan to circulate fresh air. Coat the banister with wood stain or Latex interior paint. Allow 12 hours for the stain or paint to dry.
Dampen a cotton cloth with 1 tablespoon rubbing alcohol. Rub the banister with the wet rag to deter the dog from subsequent chewing.
