So if you’re doing any kind of base coat. All you do is add reducer in base coats for the mixing ratio. Because you’re not adding any catalyst or hardener or an activator, you don’t have to worry about hardening. Base coats are always mixed with reducers, a 50:50 ratio.

Is activator the same as hardener?

From a general standpoint activators and hardeners do the same thing; initiate cure of 2K products. However, you must use only the activator each product calls for on the tech sheet and not interchange hardeners/activators from different brands or products.

How long do you wait between basecoat and clearcoat?

Allow 30 minutes after base coat color has been applied to apply the clear coat. Apply 4-5 wet (but not dripping) coats waiting 10+ minutes in between coats.

Can you add hardener to 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).
