How to Apply Rubber Paint

Suitable Environmental Conditions

Use outdoors or in a well ventilated area such as an open garage. Use when temperature is at a minimum of 55°F (13°C) and humidity is below 85% to ensure proper drying. Avoid spray application in very windy and dusty conditions. Cover nearby objects to protect from overspray.

Surface Preparation

Bare Metal or Sound Rust Surfaces- Surfaces must be free of dirt, dust, oil, grease and any contamination that may interfere with adhesion. For proper adhesion, sand the entire surface to be coated with 120-220 grit sandpaper and remove all sanding dust with a clean cloth. Protect and mask off all surrounding areas to prevent paint splatter. For best results, spot prime bare and rusted surfaces.

Previously painted/Coated Surfaces- Use a wire brush to remove any loose or peeling paint or coatings. Sand the surface with 120-220 grit sandpaper. Thoroughly rinse the area with a mild detergent and water and then allow to dry before applying Rust-Oleum Professional Undercoating.


Rust-Oleum Professional Undercoating is ready to use. Do not thin or tint. Mix thoroughly to ensure that any settled pigment has been re-dispersed. For best appearance, apply using a high quality synthetic paint brush or synthetic roller. Do not use on surfaces that will be exposed to rain or moisture within 24 hours after application. For maximum durability, apply 2 coats.
