Finish a deck with clear sealer-preservative or staining sealer. Sealer-preservatives protect wood from water and rot, and are often used on cedar or redwood because they preserve the original color of the wood.
Finish a deck with clear sealer-preservative or staining sealer. Sealer-preservatives protect wood from water and rot, and are often used on cedar or redwood because they preserve the original color of the wood. If you want the wood to look weathered, wait several months before applying sealer-preservative.
Staining sealers, sometimes called toners, are often applied to pressure-treated lumber to give it the look of redwood or cedar. Staining sealers are available in a variety of colors.
For best protection, use finishing products with an alkyd base. Apply fresh finish each year.
A hand-pump style sprayer is inexpensive and speeds up the finish application process.
Use an orbital sander to smooth out any rough areas before applying finish to decking boards, railings, or stair treads.
How to Finish a Redwood or Cedar Deck:
Test wood surface by sprinkling water on it. If wood absorbs water quickly, it is ready to be sealed. If wood does not absorb water, let it dry for several weeks before sealing.
Sand rough areas and vacuum deck. Apply clear sealer to all wood surfaces, using a pressure sprayer. If possible, apply sealer to underside of decking and to joist, beams, and posts.
Use a paintbrush to work sealer into cracks and narrow areas that could trap water.
How to Finish a Pressure-treated Deck:
Sand rough areas and vacuum the deck. Apply a staining sealer (toner) to all deck wood, using a pressure sprayer.
Use a paint brush to smooth out drips and runs. Porous wood may require a second coat of staining sealer for even coverage.
