Is hardener and activator the same?

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 much hardener do I mix with paint?

Mixing Ratios You will normally mix 4 parts paint to 1 part hardener 1 part reducer. If you need to mix part of the paint to do door jams then you should follow the same ratio. Factory Acrylics such as Kirker paints will come in a 3 quart gallon and require a full quart of hardener to be added.

6 – 8 hoursGenerally speaking, a 2k coating using a medium activator (hardner) without heat being used to accelerate the dry times, should be cured enough to clear coat in 6 – 8 hours, give or take. Using heat or IR dryer to bake it should accelerate the cure to 45 min to and hour.

Can you put hardener in basecoat?

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 nail activator the same as primer?

Some adhesive systems use so-called “primers” or “activators” that are applied to surfaces before applying the adhesive. … In other cases, the primer or activator actually is used to speed up the curing of the adhesive.

How long does it take for paint hardener to work?

Apply a cover coat of 2K paint, leave for 10-15 minutes, depending on conditions.
