Old Masters 350 VOC Interior Oil-Based Polyurethane is a self- leveling, oil-based clear finish formulated for use on interior wood, metal, and fiberglass surfaces. Easy application and quick drying, this polyurethane will provide lasting, durable protection from abrasion, marring, chipping, alcohol, and water. Great for use on interior wood surfaces such as floors, bars, counter, tabletops, cabinets, wood paneling, and doors.
All surfaces must be clean, dry, and free from dirt, wax, grease, glue and other contaminants or penetration and adhesion will be affected. DO NOT apply over sealers containing stearates.
Bare Wood: Sand the surface thoroughly with medium grit sandpaper and progress to find grit sandpaper. Always sand in the direction of the wood grain. Remove dust with a tack rag.
Previously Finished Surfaces: Surface should be sanded to remove imperfections and gloss, using extra fine sandpaper (220 grit), sanding with the grain. Remove dust with a tack rag.
Stained Surfaces: Stain must be thoroughly dry before applying clear finish. Do not sand un-coated stained surface.
Stir thoroughly before and during application. DO NOT SHAKE. For larger projects requiring more than one container, combine containers and mix to ensure gloss uniformity. Do not apply in direct sunlight or areas of extreme air movement.
- Apply with a pure bristle or polyester brush, low nap applicator or spry. Allow nap applicator is suggested for large flat areas, such as floors.
- Apply a thin coat. * Flow on with minimum brushing to achieve a glass-like finish. For wood floors, use a low nap applicator or a natural bristle brush and maintain a wet edge to avoid lap marks. Keep area dust free.
- Polyurethane will dry to touch in 6 to 8 hours. Overnight drying is recommended.
- Sand lightly between coats with fine sandpaper (220 grit) to produce a finer finish and promote adhesion. If sandpaper gums up allow more dry time. Remove sanding dust.
- Reapply. For most projects, two coats are recommended. For maximum durability on floor applications, we recommend three coats.
*This product is specially formulated with a higher concentration of resins and solids, leading to a thicker consistency. We highly recommend applying in thin coats.
Do not thin. Use as packaged.
Approximately 350-500 square feet per gallon depending upon method of application, type, and porosity of wood.
Apply when air and surface temperatures are between 60 and 90 F and humidity is between 30% and 70%. At 50% relative humidity and 70°F, Interior Oil-Based Polyurethane will dry to touch in 6 to 8 hours. Overnight drying is recommended before recoating. Dry time will be affected by temperature, humidity, and film thickness. Protect product from freezing prior to and during application.
Wait 24 hours before subjecting surface to light use. Care should be used during the first week after application as the finish is curing to its ultimate hardness. In floor applications, avoid heavy traffic and replacing for furniture for 72 hours after the final coat. When replacing furniture, do not slide. Do not install rugs or clean floors for 7 days.
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.

Why use clear finishes?
Clear finishes are used to seal and protect surfaces. In many cases, clear finishes offer lasting, durable protection from abrasion, marring, and chipping. Most clear finishes also protect the surfaces from damage caused by water and alcohol. Exterior clear finishes provide protection to withstand water, weather, and sunlight.
- Fine grade sandpaper or nylon sanding pad
- Tack cloth
- Stir stick
- Drop cloth
- Quality, China bristle brush
- Mineral spirits or paint thinner
- Rubber gloves
