National Paints N.C. Sanding Sealer 3.6L for Medium-Size Wood & Metal Projects

It’s suitable for a variety of surfaces including wood, metal, glass, plastic, as well as MDF and other composites. It helps level the surface and prepare it for the final topcoat.

The sealer penetrates and seals the surface to reduce grain raise, resulting in a smoother base. It dries to a hard, durable film that provides excellent adhesion for subsequent coats and minimizes brush marks.

Key specs include a 3.6L capacity, alkyd-nitrocellulose formulation, suitability for multiple surfaces (wood, metal, glass, plastic, MDF), fast drying, and a finish that resists yellowing. It’s designed for both indoor and outdoor applications and helps seal grain for a topcoat.

Stir the can well before use. Apply a thin, even coat with a brush or roller, maintaining a wet edge to avoid lap marks. Allow to dry to a touch, then lightly sand to smooth the surface before applying a second coat if needed. Between coats, sand lightly to promote adhesion for the next layer.

Typically one to two coats are used, depending on the surface and desired smoothness. Let each coat dry before sanding and applying the next; sanding between coats helps achieve the best adhesion for the final topcoat.

Yes, it’s formulated to work on MDF and other common composite materials. Proper surface preparation and light sanding between coats will help ensure a smooth, uniform finish.

Use in a well-ventilated area and away from heat or open flames due to solvent content. Wear appropriate PPE such as gloves and eye protection, and avoid inhalation. Store and dispose of leftover material according to local regulations and consult the product SDS for detailed guidance.

Store the container tightly sealed in a cool, dry place away from heat sources. Dispose of any leftover material or emptied containers according to local hazardous waste regulations and your area’s guidelines.

The formulation is designed to resist yellowing, making it suitable for both indoor and outdoor applications where a clear, durable seal is desired.
