Old Masters® Interior Oil-Based Sanding Sealer is designed to seal and protect wood surfaces and can be used to prepare surfaces for the application of a clear topcoat finish.
Where to Use
Old Masters® Interior Oil-Based Sanding Sealer is recommended for use on interior wood surfaces as a sandable basecoat or sealer prior to the application of a clear topcoat finish. It may be applied to all types of bare or stained woods.
All surfaces must be clean, dry and free from dirt, wax or grease.
New Wood: Sand the wood thoroughly with medium grit sandpaper and progress to fine grit sandpaper; this will help to create a smoother finish. Always sand in the direction of the wood grain. Sand smooth and remove dust with a rag dampened with mineral spirits.
Previously Finished Surfaces: Restore previously finished surfaces to bare wood by removing old finishes with a paint or varnish remover or by sanding. When applying over stained wood, ensure stain is thoroughly dry. Remove all dust prior to application.
WARNING! If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.
Stir thoroughly before and during application. DO NOT SHAKE. Sanding Sealer can be applied with a pure bristle or polyester brush, or sprayed.
- Apply sealer liberally with the grain, then level with light, even strokes. Avoid excessive brushing. One coat thoroughly seals and prepares the surface for succeeding coats of clear finish.
- Allow surface to dry approximately 2 to 3 hours. Surface can be sanded after 3 hours depending on temperature and humidity.
- Ensure surface is thoroughly dry before sanding. Smooth sealer by sanding with fine sandpaper. Be careful when sanding not to sand through the sealer film and remove the stain color.
- Remove any sanding dust using a tack rag, then wipe the surface with a cloth moistened with mineral spirits. Topcoat with varnish or polyurethane clear finish.
Do not thin. Use as packaged.
Approximately 300 to 450 square feet per gallon depending on the type and porosity of the wood.
Apply when air and surface temperatures are between 60° and 90°F and humidity is between 30% and 70%. Interior Oil-Based Sanding Sealer will dry to touch in 2 to 3 hours and can be sanded after 3 hours or when sanding sealer is thoroughly dry.
Using a cleaning solvent, such as paint thinner or mineral spirits, is recommended for cleanup. The use of paint thinners or mineral spirits may violate VOC compliancy in your area. Check with your local government agencies to ensure proper compliancy.
To avoid spontaneous combustion during temporary storage, soak soiled rags and waste immediately after use in a water-filled, closed metal container.
MAX VOC: 550 grams/liter (4.6 lbs/gal)
Proper Surface Preparation
Proper surface preparation can be the most important step of any stain or finish project. Below are some helpful tips that will help you achieve a professional looking finish every time.
FILLING WOODGRAIN Some open-pore wood species or woods with large imperfections may require an additional step to prepare the surface for staining and finishing. Creating a smooth finish on these woods can be obtained by using Old Masters® Woodgrain Filler. Use on hardwoods, such as oak, ash and mahogany. Use as directed.
CONDITIONING Some woods like pine, fir, maple and poplar absorb stain unevenly creating a blotchy appearance. Old Masters® Wood Conditioner is a clear wood sealer which enables uniform stain application under oil or water based stains. Stain must be applied over Wood Conditioner within 2 hours. Ideal for use on soft woods which are being stained with or adjacent to hardwoods.
SANDING SEALERS Use a sandable basecoat or sealer prior to the application of varnishes or polyurethanes. Old Masters® Oil-based and Water-Based Sanding Sealers may be applied to all types of bare or stained woods. Using these products helps to promote a smooth, fine finish.
