National Paints Synthetic Varnish Gloss I, 18L, Used for High-Gloss Wood Protection - Clear

It can be applied to interior wood, and is suitable for use on metal, masonry, plaster, and other common interior substrates. It’s versatile for furniture, cabinets, doors, trim, and other interior woodwork.

Gloss I is part of a line that offers various sheens from low-gloss satin to high-gloss gloss. For furniture, a higher gloss can highlight grain and provide a durable topcoat, while satin finishes offer a more subdued look with easier touch-ups.

The varnish dries quickly and can be recoated in as little as two hours, depending on temperature and humidity. For best results, apply thin, even coats with a brush, roller, or spray, and allow each coat to dry before light sanding and applying the next.

This water-based varnish provides long-lasting protection against moisture and wear, with good resistance to cracking and yellowing. It’s designed to maintain clarity and provide a durable surface for interior woodwork.

Yes. It’s a water-based, environmentally-friendly formula that cleans up with soap and water and is suitable for indoor applications with proper ventilation.

Prepare the surface by cleaning to remove dust, grease, and oils. Lightly sand to create a smooth, even surface, wipe away dust, and ensure the surface is dry before applying the first coat.

Cleanup is with soap and water. If you need to recoat, make sure the previous coat is dry and lightly scuff-sanded for good adhesion before applying the next coat.

While designed for interior wood surfaces, it can be used for certain exterior projects under appropriate conditions. Check product guidelines and consider exterior-grade options if you expect prolonged exposure to weather.

Coverage depends on substrate and application method, but typically multiple thin coats are recommended for best protection and finish. Refer to the product label for exact coverage per liter andcoat recommendations for your project.
