Exterior 450 Water Based Topcoat, 1 Quart, Flat

General Finishes Exterior 450 is a fast-drying finish fortified with UV absorbers and built-in mildewcides to protect against fading and inhibit mold and fungus growth. This versatile finish is perfect for outdoor furniture like Adirondack chairs, benches, and trellises for your porch or patio. It dries quickly, allowing you to sand within one hour under ideal conditions and finish your project efficiently.

It's important to note that clear topcoats should not be applied over bright white paint to avoid potential yellowing, as it may react with the substrate. While light-colored paints may also experience some yellowing from topcoat application, it will be less noticeable. Exterior 450 Topcoat, on the other hand, is designed to stabilize and protect the finish with UV absorbers, but it will not prevent the natural color change of the wood due to sunlight exposure.

This water-based formula can be applied with a brush, sprayer, or roller, and cleanup is a breeze with just soap and water. Get your outdoor projects finished quickly and beautifully with General Finishes Exterior 450 Topcoat.
