Hardener for Acrylic-Polyurethane Water-based Paint

Our hardener ensures better drying and hardening of acrylic-polyurethane paints, by "polymerisation" (chemical reaction) in addition to traditional drying by evaporation, specific to water-based paints in general.

The hardener is added to the paint before use (1 to 4% maximum).

We don’t recommend its use for drawing paints, but rather to solidify the final coats, which will be exposed to external aggressions.

Warning: the product has a short shelf-life not exceeding 1 to 3 months. The product is sensitive to air.
