How to Redo a Fireplace Mantle

Locate the nails or screws holding the mantel in place and remove them. Test the mantel to see if it can be removed easily. Use a soft-headed mallet wrapped in fabric to gently bang on the mantel from the underside to loosen any old glue, if necessary.

Take the mantel outdoors or into a room that is very well-ventilated. Lay the mantel onto a flat surface, such as across a pair of wooden sawhorses. Put on a pair of rubber gloves and some safety glasses, since you will be using chemicals.

Cover the entire mantel with a generous layer of semi-paste chemical stripper. Let the stripper sit undisturbed until you see the surface of the old finish begin to blister. Scrape away all of the old finish using a paint scraper; scrub difficult areas with medium-grade steel wool.

Use a damp rag to remove all of the stripper thoroughly; you can first use lacquer thinner to rinse off the stripper, but then you must remove the thinner very well with the rag. Make sure that no traces of the chemical stripper or the thinner remain on the mantel. Dry the mantel quickly; do not let the moisture sit on the surface, since the wood may warp.

Test the new stain in an inconspicuous spot, such as the back of the mantel, which will be against the wall and not visible when it is hung. Decide whether or not you are happy with the color. Apply the stain to the entire mantel with a paintbrush, working only in one direction so that it does not streak.

Let the stain dry overnight. Use a clear topcoat resistant to seal the finish of the mantel. Apply the stain in a thin, level layer with a clean paintbrush; let the topcoat dry overnight and reinstall the mantel.
