How to Apply Zinsser Bulls-Eye Seal-Coat Universal Sanding Sealer
Surfaces must be clean, dry, sound and free of dust, dirt, grease, oil, wax, mildew, or any contamination that may interfere with adhesion. Remove any peeling and/or unsound coatings. Sand bare wood as smoothly as possible and remove all sanding dust. Previously applied wood stains must be completely dry. Previously applied finishes must be clean and tightly adhered.
Apply only when air, material, and surface temperatures are between 50-90ºF (10-32ºC) and the relative humidity is below 85%. Do not thin this product when using as a sealer or bond/barrier coat. Apply evenly and consistently and allow to dry 45 minutes before sanding with 120 or finer grit sandpaper. Remove all dust and apply a finish coat. Note: A second coat of sealer will improve the film build and give added depth to the final finish on porous or open grain woods such as oak or mahogany. Allow the second coat to dry 1 hour before sanding lightly and applying a finish coat.
Brush Application – For best results, use a natural bristle brush. Apply the sealer to the surface using long and even strokes, brushing back into the wet material to maintain a wet edge. Do not over-brush or brush back into material once it becomes tacky.
Wiping Application – Use a lint-free cloth. Pour a liberal quantity of SealCoat onto the surface and quickly work into the wood. Use a brush to make sure the sealer soaks thoroughly into any open or end grain. Wipe away excess with a lint-free cloth and stop wiping when the surface becomes tacky. For vertical surfaces pour SealCoat onto a lint-free cloth and wipe over the wood surface. A second application may be needed to avoid sanding through the sealer and the stain.
Spray Application –SealCoat may be sprayed using conventional, HVLP, or airless spray. Use a 0.011 to 0.013 tip and 800-1000 psi for airless spray application. Follow equipment manufacturer’s instructions. Wear NIOSH approved respirator and provide adequate ventilation.
Doors/Trim/Paneling/Cabinets/Furniture – Apply 1 or 2 coats by wiping, brush or spray. Allow to dry completely before sanding with 220 or finer grit sandpaper between coats to ensure a smooth finish. If a heavier film build is desired, repeat the application. Be sure to remove all sanding dust before application of finish.
