PRODUCT APPLICATION
SURFACE PREPARATION
To ensure proper adhesion, surfaces must be clean, dry, and free of old finishes, dirt, oils or other foreign matter. Old finishes in poor condition must be removed. Sand the area smooth, progressing with 120 to 220 grit sandpaper and vacuum surface to remove dust. Do not use steel wool as rust may develop after the finish has been applied. Wipe surface with clean, lint-free cloth.
UNFINISHED SURFACES – Sand using 180-220 grit sandpaper and remove all sanding dust using a vacuum, tack cloth, or rag dampened with mineral spirits. If a filler or putty is used, make sure it does not contain wax and allow enough time for it to dry thoroughly.
STAINED OR PAINTED WOOD – Apply stain prior to applying Varathane Sanding Sealer. Follow the manufacturer’s directions for application of the stain. Allow the stain to thoroughly dry before applying Varathane Sanding Sealer. Refer to the stain manufacturer’s label for dry times.
APPLICATION
Use in an area with adequate ventilation such as an open garage. Apply only when air (ambient) temperature is between 55-90°F (13-32°C) and relative humidity is below 85%. Use full strength. Do not thin. Stir thoroughly before and during use. To prevent bubbles in the finish, DO NOT SHAKE, do not over-brush, or apply with a roller.
Apply using a good quality synthetic bristle brush, foam brush or applicator. Apply in the direction of wood grain in smooth, uniform coat. Lower temperatures and/or higher humidity may cause slower dry times. Lightly sand the surface with 220-280 grit sandpaper. A powder should develop when sanded. Do not over-sand to avoid removal of the sanding sealer or previous stain. Remove sanding dust with a vacuum or a clean lint-free rag.
Once the sanding sealer is dry, apply the wood finish of choice. For best results, use any Varathane Polyurethane. Follow the manufacturer’s direction. Allow the finish to dry 24 hours before light use. Wait 3 days before subjecting surface to normal use.
