Exterior 450 Water Based Topcoat, Satin, 1 Gallon

Exterior 450 Topcoat is a clear-drying finish suitable for vertical exterior surfaces, such as fences, patio furniture, garage doors, entrance doors, and interior windows. It is not recommended as a deck finish. This topcoat is fortified with UV absorbers to stabilize the finish and built-in mildewcide to retard mold and mildew growth. It performs well as a clear coat or as an optional topcoat over General Finishes Milk Paint.

However, it is important to note that clear topcoats should not be applied over bright white paint, as yellowing may occur due to a reaction to the substrate. Additionally, light color paints may also experience some yellowing due to topcoat application, but it will be less noticeable.

The Exterior 450 Topcoat is fortified with UV absorbers to stabilize and protect the integrity of the finish, but it will not prevent the wood from changing color from sunlight. The water-based formula can be brushed, sprayed, or rolled, and cleanup is done with soap and water.

This topcoat is designed to provide a durable and protective finish for outdoor surfaces, while also offering some level of UV protection. It is suitable for a variety of exterior applications, including fences, furniture, and doors, but should be applied with caution over certain light-colored paints to avoid unwanted discoloration.

The water-based formula makes it easy to apply and clean up, and the built-in mildewcide helps to prevent the growth of mold and mildew, which can be a common issue for outdoor finishes. Overall, the Exterior 450 Topcoat is a versatile and reliable choice for protecting and enhancing the appearance of exterior surfaces.
