WARNING ICON G 001
WARNING: Use care when finishing an unfinished
mantel. Do not finish mantel pieces near running
heater or open flame. Vapors from most finishing
products are highly flammable. Follow manufacturer’s
guidelines when using finishing products.
IMPORTANT:
If you are staining an unfinished mantel, sand entire
outside of mantel to remove any dirt or oils. This will prevent
blemishes from appearing under the stain. Stain mantel according to
manufacturer’s instructions. Apply sanding sealer.
IMPORTANT:
If you are painting an unfinished mantel, apply an
oil base undercoat to the mantel before painting. This will seal the
wood. After undercoat dries completely, lightly sand and apply an
oil base top coat. If you do not apply an oil base undercoat and
topcoat, the wood grain will bleed through the paint.
