1K Paint

1K paint, also called single-component paint, is a type of coating that does not require a chemical reaction to completely cure. It does not require mixing and is ready to use. Pros of 1K paint include:

Quicker drying times
Easy to use

However, since they don’t use a chemical reaction, 1K automotive paint supplies are not as strong, making them unsuitable for high-stress or heavy use areas.

2K Paint

On the other hand, two-component systems combine the base coat with a hardener or activator to create a chemical reaction. Pros of 2K paint include:

More durable
Chemical-resistant

Keep in mind that 2K automotive paint supplies are generally harder to use, since they require exact mixing ratios for the the right reaction. If you are less experienced, opt for 1K supplies, which generally have less of a learning curve.

Should I Use 1K or 2K Paint?

1K Uses

We recommend 1K for:

Small Repairs: Touching up a small scratch? When used with the proper clear coat, 1K paint works well for small areas. However, keep in mind that a one component system will never been as durable or resistant as a two component system.
Easy Touch-Ups: Don’t care about the aesthetics? Looking for something quick and easy? 1K paint will do the trick. These automotive paint supplies are great for farm equipment, ATVS, or other equipment that experiences regular wear and tear.

2K Uses

Choose 2K paint for:

Showroom Quality Finish: Want to see your reflection in your paint job? If so, you’ll need 2K paint. The finish of this system is much glossier and shiny than 1K options. If you are looking for a pro-level finish, talk to the CAPS team for finish and brand recommendations.
Underwater Use: Painting the hull of your boat? 2K paint is a must. Because of the chemical reaction, 2K paint helps to completely seal your equipment and create a waterproof membrane.
