  • Proper surface preparation is required. Wood Surfaces: Replace rotting or unstable boards and remove loose splinters. For failing coatings or to remove loose wood fibers, use a product such as KILZ Wood Stain & Finish Stripper followed by KILZ Wood Cleaner & Brightener to neutralize the wood. When KILZ Wood Stain & Finish Stripper is not needed, a product such as KILZ Wood Cleaner & Brightener MUST  be used to remove mill glaze and clean the wood surface. After using either KILZ Wood Stain & Finish Stripper or KILZ Wood Cleaner & Brightener, rinse thoroughly with a garden hose or pressure washer. When rinsing with a pressure washer, use the broadest spray pattern while keeping the nozzle at least 0.6 m away from the surface. Allow the area to dry at least 24 hours before coating. Lightly sand to remove remaining wood fibers/fuzz. Concrete Surfaces: Avoid areas that are structurally weak or subject to hydrostatic pressure above 8 psi. Allow new surfaces to cure for 30 days. Use a product such as KILZ Concrete & Masonry Paint Stripper to strip peeling coating. Use a product such as KILZ Concrete & Masonry Cleaner & Etcher to clean and etch uncoated concrete or KILZ Concrete & Masonry Degreaser & Cleaner on sound, coated surfaces prior to coating. See for additional product information.


  • Use product when air and surface temperatures are between 10°C - 32°C. Avoid applying in direct sunlight or to hot surfaces. Do not use if rain is expected within 24 hours. The surface must be completely dry before application. Avoid painting if humidity is expected to be greater than 80%. Intermix multiple containers to ensure colour uniformity. Stir product occasionally throughout application. DO NOT THIN PRODUCT. For nail holes and cracks up to 6 mm, completely fill in with Over Armour Smooth using a nylon/polyester brush and allow to dry prior to rolling. Deep nail holes and cracks may require additional filling. For edges, corners and in between wood boards, apply using a nylon/polyester brush. Use pressure while rolling and apply a generous, even coat using a 1/2" nap roller. For a smoother texture, use a brush or thinner nap roller (i.e. 1/4"). For vertical surfaces such as railings, use a nylon/polyester brush or roller and apply two thin coats at a spread rate of 400 sq. ft. per gallon. Airless spray is recommended for experienced applicators only; use a .027"- .035" tip with no filter at 2400-3200 psi. When spraying vertical surfaces, apply a very thin coat (one pass only) and do not back brush/roll. When spraying horizontal surfaces, follow the standard spread rate of 7 m² per 3.79 L. For optimum performance, film uniformity, leveling and to cover cracks, a second coat MUST be applied. Maintain a wet edge when applying.

    COVERAGE: 7 m² per 3.79 L based on recommended 2 coats per project.

    DRY TIME:  4-6 hours before recoat. Dries to touch in 4 hours. Wait 24-48 hours before light foot traffic. 72 hours to full cure. Additional dry time may be needed in cooler temperatures and higher humidity. Premature heavy traffic will cause coating failure.
