How to Finish a Wood Mantel Shelf How to Finish a Wood Mantel Shelf
A wood mantel shelf is ideal to cap your fireplace mantel, adorning it with a decorative fixture, as well as providing a practical space for candelabras, books, photographs or other keepsakes. Once you choose the style of mantel shelf you wish to install, it needs to be finished to both protect the wood from overexposure to air and moisture, as well as to decorate it. Opting for paint is one way to coat and adorn it. Depending on the decor of the room and the mantel itself, staining it may be a better choice of finishes. Natural wood stain comes in numerous colors, shades and types. Glazing is another option: the process of combining stain or paint with a solvent to create a rustic look. Ultimately, though, how you finish the mantel shelf is a matter of personal taste and style coordination.
Step 1: Inspect and Fill in Blemishes
Look over the wood mantel shelf thoroughly and keep an eye out for any inconsistencies or blemishes. Any cracks, gaps or holes in the shelf need to be filled in with wood putty. Put a small amount on the putty knife and scrape it over the holes or gaps, working it in first with the knife. Use your finger to smooth out the fill-in.
Step 2: Sanding
Especially at the places you applied putty, sand the shelf with a medium grit sandpaper, and then with a fine grit sandpaper. Make sure all the edges are smooth and that there are no splinters or rough patches. Where you applied putty, sand those areas until you can feel little difference between the wood and the putty.
Step 3: Wipe Down
With a clean, lint-free rag, wipe the entire shelf down to get all dust and debris off before you stain it. Anything left on will end up disrupting the application of the stain.
Step 4: Staining
Because there are so many types of stain, it is hard to account for the differences in application instructions. There are, however, some general application guidelines. You should always go with the grain when applying stain, whether by brush, sponge or rag. Any runs in the stain wipe away immediately. Hold a clean rag in one hand. As you apply stain with a brush or sponge, use the rag to rub it into the wood. Penetrate the wood grain thoroughly. Depending on the type of stain, brand and how dark you want the shelf, you may have to apply more than one coat.
Step 5: Finish
On top of the stain you will apply a clear finish that will seal and protect the wood from corrosion. Because it’s near the fireplace, you should choose a finish that can withstand higher temperatures. It may not get that hot, but it’s better to be safe than sorry. Apply the clear coat with a clean brush in even strokes. Again, you do not want to end up with any runs. Ideally, no evidence of the finish will be visible. A sponge may work better to achieve the right effect.
After staining your wood mantel shelf you will finish it with a clear protective coating. It helps to have the room ventilated, as the finish can be quite pungent. Before applying either a second coat of stain or the finish, let the entire shelf dry thoroughly.
