The Designer Metallics™ system is a two part system which allows for custom color mixes. Part A (Designer Metallics™) is a custom reflective color material dispersed in a proprietary co-polymer acrylic resin system.

This system produces elegant, metallic basecoats developed for the interior design and architectural trades. The appropriate amount of Designer Metallics™ Concentrate Silver (Part B) is included (for no charge) with your purchase of any Designer Metallics™ base (Part A), however you must purchase separately if would like additional concentrate.
