Because wooden ladders are subject to heavy use, they are finished with a protective layer of varnish. Eliminate this coating before you apply a new finish, or the new finish could flake. It's also important to apply the stain properly, or the finish could dry blotchy. Finish the ladder with a fresh coat of varnish to ensure many years of continued use.
Things You'll Need
- 180-grit sandpaper
- Tack cloths
- Heavy-duty fabric drop cloth
- Oil-based stain
- 2- to 3-inch natural-bristle paintbrush
- Mineral spirits
- Polyurethane varnish

Sand the ladder until the finish appears dull. Always sand with the grain, or the wood could splinter.
Clean the sawdust from the ladder, using a tack cloth. Don't skip this step, or absorption problems may result.
Use a 2- to 3-inch natural-bristle brush to coat the wooden ladder with oil-based stain. Wipe the wet stain from the rungs and rails, using clean rags. Allow the ladder to dry for four hours.
Wash your brush with mineral spirits.
