Applying a Sanding Sealer Instructions

  • Applying a Sanding Sealer

    Sanding sealers, also known as first-coat sealers, are recommended when refinishing furniture. Although it’s a good step to take regardless of the type of stain you’re using, a sanding sealer is especially necessary when using water-based stains. Apply it after you’ve bleached your furniture, but before staining. A sanding sealer provides an important barrier to keep the wood pitch and stain from bleeding into the water-based topcoat. It also helps fill small pits and pores present in hardwoods such as oak, ash, mahogany and teak, and it helps you attain a smooth, level surface. This is especially important on tabletops, dressers and bureaus.

  • Overview

    Applying a sanding sealer is easy. Always work on furniture that’s been stripped to bare wood. Start by thoroughly dusting the piece. Then apply the first coat of sanding sealer. After allowing the furniture to dry for an hour or two, lightly sand it and dust again. And apply one final coat.

  • Dust Thoroughly

    Make sure your furniture is dust-free before sealing. Use a small paintbrush to clean joints, grooves and detail areas as well as flat surfaces. Then wipe the piece with a clean, dry rag. Now you’re ready to start sealing.

  • Shake and Stir

    Turn the unopened can of sealer upside down and vigorously shake it for several seconds. Open it and stir thoroughly with a wooden stir stick.

  • Apply First Coat

    Using a small paintbrush, apply a thin coat of sealer to the joints, grooves and detail areas. Be careful to not allow the sealer to puddle in or fill in decorative grooves. Apply in small areas at a time, taking care to not over-brush or to allow the sealer to drip onto other areas. Use a larger brush in flat, broad areas. Work from a wet edge and avoid overlapping or overbrushing. Use only a small amount of sealer at a time.

  • Dry, Sand and Dust

    Let your furniture dry for one to two hours. Then lightly sand it with fine grit sandpaper, always working in the direction of the wood grain. Remove the sanding dust with a clean brush and a clean dry cloth, and vacuum or remove sanding dust from your work area to avoid contamination.

  • Apply Second Coat & Allow to Dry

    Apply a second coat of sealer, repeating the process. Allow at least two hours of drying time, and longer in cooler, damp or humid weather. You won’t ever need more than two coats. After cleaning up tools and your work area, you’re ready to apply your stain. See the next tutorial to learn how to properly stain your furniture.
