Strip Off Old Finish
Remove the door from its hinges. Set it on a workbench or workhorses. Tape off hardware.
Strip off the old finish. Use a commercial stripper. Follow the manufacturer's instructions. Essentially, you apply the stripper to door, allow it to break down the finish, then remove old stain and varnish with a plastic scraper and old rag.
Wash door after stripping old finish. Do not saturate the door with water. Use a spray bottle filled with plain water, along with a clean cloth to wash the door and remove any remnants of the stripping chemical.
Dry it for several hours or overnight. Allow the door to dry in a protected spot before continuing.
Sand the door. Begin with a medium grade of sandpaper and sand lightly. Use a clean, soft brush to brush off the sanding dust. Next use a fine grade of sandpaper and sand lightly. Then use a soft brush to brush off sanding dust. Finally, sand lightly with an extra fine grade of sandpaper. Again, use a soft brush to brush off sanding dust.
Stain and Re-finish Door
Prepare surface of door for staining. Wipe the entire door with a tack cloth to remove any remaining particles of sanding dust.
Stain the door. Use an old soft cloth to apply the stain. Work in small areas at a time. First, apply stain to cloth and wipe it over a small area of door. Then take a clean cloth and wipe off excess stain. Repeat until entire door is stained. Complete this in one session to avoid demarcation of stain between areas done at different times.
Allow stain to dry as recommended by stain manufacturer.
Use extra fine grade of sandpaper or extra fine steel wool and lightly sand stained surface of door.
Use tack cloth to remove all particles of sanding dust.
Apply exterior grade varnish or polyurethane finish. Use a paintbrush. To minimize brush marks, don't brush over areas you've already painted with finish.
Allow finish to dry as recommended by manufacturer.
Sand lightly with extra fine sand paper or steel wool.
Use a tack cloth to remove sanding dust.
Apply a second coat of exterior varnish or polyurethane finish. As with the first coat, allow to dry, sand lightly and wipe off sanding dust. If desired, you can apply three or even four coats of varnish or polyurethane finish. Remember to sand and remove sanding dust between coats.
