What You'll Learn
Behr DeckOver can be applied to painted vertical surfaces
Behr DeckOver is a coating that resurfaces existing wooden decks by filling in cracks and taming splinters, extending the life of the deck. It can be applied to both uncoated and previously coated concrete surfaces. The product is designed to be used when air and surface temperatures are between 50-90˚ F (10-32˚ C). It is important to avoid exposure of the container to direct sunlight during application and to not apply it if rain is expected within 24 hours.
To apply Behr DeckOver to vertical surfaces, use a nylon/polyester brush or roller and apply two thin coats at a spread rate of 400 sq. ft per gallon. For nail holes and cracks up to 1/4", fill them completely with DeckOver coating using a brush and allow to dry before rolling. Deep nail holes and cracks may require additional filling. For a smoother texture, use a brush or thinner nap roller (i.e. 1/4").
It is important to properly prepare the surface before applying Behr DeckOver. Remove any dirt, oil, grease, mildew, or any other debris or stains on the surface. The surface must be completely dry before application, with a minimum of 24 hours of dry time. If you live in a high-moisture region or if weather conditions are damp, allow for a longer dry time. Replace any rotting or unstable boards and use a product such as BEHR PREMIUM® Wood Stain & Finish Stripper to remove failing coatings if necessary.
While Behr DeckOver can be applied to painted vertical surfaces, some users have reported issues with the product. Some reviews mention that the product started peeling off after a year or two of application, while others have mentioned that it paints on lumpy and the color turns dull after drying. It is important to carefully follow the instructions and properly prepare the surface to achieve the best results.

Prep work is important for painted surfaces
Behr DeckOver can be applied over a painted surface, but it is important to note that proper preparation and application are key to achieving a successful and long-lasting finish. Here are some reasons why prep work is crucial when dealing with painted surfaces:
Ensuring Adhesion and Preventing Peeling
Painted surfaces can present adhesion challenges, and inadequate preparation can lead to premature peeling. Before applying Behr DeckOver, it is essential to remove any loose paint by scraping, pressure washing, or using a suitable paint stripper. This creates a smoother surface for the new coating to adhere to.
Avoiding Moisture Damage
Behr DeckOver is designed to be applied to completely dry surfaces. If the painted surface is not thoroughly dried, the new coating may trap moisture underneath, leading to wood rot and other issues. Allow ample time for the surface to dry, especially in high-moisture regions or damp weather conditions.
Achieving a Smooth and Uniform Finish
Prep work helps create a smooth and uniform base for the new coating. Sanding or using a suitable primer can help smooth out uneven paint layers and create a more even surface. This is especially important if the previous paint job is old or deteriorating, as DeckOver can accentuate existing imperfections.
Maintaining Colour Uniformity
Proper preparation ensures colour uniformity in the final finish. This includes ensuring that the painted surface is clean and free of any dirt, grease, or mildew stains that could affect the adhesion and appearance of the new coating. A clean surface also helps the DeckOver coating spread more evenly, resulting in a consistent finish.
Protecting Against Weathering
Behr DeckOver provides excellent UV protection, but prep work is crucial to maximizing its effectiveness. Proper preparation, such as ensuring the surface is clean and dry, helps create a strong bond between the coating and the painted surface, reducing the likelihood of peeling or cracking due to weather exposure.
In summary, prep work is vital when applying Behr DeckOver to a painted surface. It ensures proper adhesion, prevents moisture damage, achieves a smooth and uniform finish, maintains colour uniformity, and enhances the coating's protective qualities against weathering. Following the recommended preparation steps will help ensure a successful and long-lasting application.

Behr recommends stripping paint before applying DeckOver
Behr DeckOver can be applied to painted surfaces, but Behr recommends stripping paint before applying DeckOver. This is because DeckOver is designed to resurface existing wooden decks by filling in cracks and taming splinters. If the paint is not stripped beforehand, it may affect the adhesion of the DeckOver coating.
Behr recommends using a product such as BEHR PREMIUM® Wood Stain & Finish Stripper to remove failing coatings, such as peeling paint, before applying DeckOver. This will ensure that the DeckOver coating adheres properly to the surface and help to achieve a beautiful and long-lasting finish.
In addition to stripping paint, Behr also recommends replacing any rotting or unstable boards and removing loose splinters before applying DeckOver. The surface should be cleaned with water and appropriate cleaning products, such as BEHR PREMIUM® NO. 63 All-In-One Wood Cleaner, to remove any dirt, oil, grease, mildew stains, or other debris. After cleaning, the surface should be allowed to dry for a minimum of 24 hours before applying DeckOver.
It is important to follow the recommended surface preparation and application steps when using DeckOver. This includes using the right tools, such as a 1/4"-1/2" nap roller or a nylon/polyester brush, and applying the product when air and surface temperatures are between 50-90˚ F (10-32˚ C). Proper preparation and application are key to achieving the best results with DeckOver.
While DeckOver can be applied to painted surfaces, it is important to note that some users have reported issues with peeling and poor adhesion, even after following the recommended preparation and application steps. Therefore, it is essential to carefully consider the condition of the surface and follow Behr's recommendations for surface preparation to ensure the best results.

DeckOver can be applied over concrete
To apply DeckOver to concrete, the concrete surface must be properly prepared. The concrete should be structurally sound and not subject to hydrostatic pressure above 8 psi. New concrete surfaces should be allowed to cure for 30 days. Use a stripper product to remove any peeling coating and a cleaner to remove any dirt, oil, grease, mildew, or other debris or stains. If you live in a high-moisture region, allow for a longer dry time.
Once the surface is clean and dry, apply the DeckOver coating generously and evenly, using a roller or brush. For best results, use a 1/2" roller cover or a 1/4"-1/2" nap roller for a smoother finish. Work the roller into a paint tray until it is fully loaded with coating. Apply pressure while rolling and use a thinner nap roller for vertical surfaces. Allow ample dry time before exposing the surface to foot traffic.
It is important to note that DeckOver should not be applied if rain is expected within 24 hours and the surface and air temperatures should be between 50-90˚ F (10-32˚ C) during application. Additionally, do not apply DeckOver in direct sunlight as this may affect the final appearance.
