A new puppy is adorable, but he's also likely to view everything in your home as a chew toy -- especially that gorgeous wooden furniture you have. Even older dogs may give in to the temptation that a sweet morsel of chair leg presents. You don't have to declare your chair a loss if this happens. Even badly chewed wooden chairs can be restored to like-new condition with the right tools and the right techniques.
1 Use a coarse piece of sandpaper or sandpaper block to smooth out the chewed area. You don't have to get rid of the chew marks; you just have to clear the area of debris and make it smooth enough to accept filler.
2 Clear the area of sawdust and debris and apply a wood filler. You can use a basic filler or an epoxy, whichever you prefer and whichever is available. Use a putty knife to fill the area, covering all holes and dents.
3 Use a medium-grit sandpaper to smooth out the filler after it has dried. If there are big raised areas, you can use a carpenter's knife or razor blade to carve away some of the filler.
4 Continue sanding until the filler lies flush with the surrounding wood and there are no raised or uneven surfaces.
5 Apply a matching stain or paint to the area that has been filled. Limit your application only to those areas that have been repaired or you may risk deepening the surrounding stain and making it difficult to get a match.
6 Apply a lacquer or varnish once the stain or paint is dry to protect it. You can spray or paint the lacquer on over the whole area. There is no risk to overlapping your varnish.
7 Use a fine sandpaper to sand and smooth the area after the lacquer has dried completely. Apply a second coat of lacquer or varnish.
