Artisan Real Rust is a two step process that produces the perfect rusted patina to just about any surface! Simply paint a generous amount of base coat, and when touch dry, paint on a coat of activator. Within 30 minutes rust will appear and continue to develop similar to how iron rusts. The reaction can be accelerated by lightly misting with water until desired amount of rusting occurs. We recommend Sealing with Artisan Flat Matte Sealer to prevent further rusting and staining on light flooring. Perfect for use outdoors once sealed. Wear personal protective clothing such as gloves and eyewear when using this product as the base coat contains minute iron filaments and the activator is mildly corrosive.
