Ideal Environmental Conditions

Do not apply to surfaces, when heated, exceed 200°F (93°C). Avoid spraying in very windy and dusty conditions. Cover surrounding area to protect from spray mist.

Clean area to be primed with mineral spirits to remove all oil, grease, wax, and dirt. Remove loose paint with a wire brush or sandpaper. Lightly sand glossy surfaces.

Hold can 12-16" from the surface and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface. Keep the can in motion while spraying.
