How to Mix Mipa Paint Hardener

Updated July 20, 2017

When painting your car, using vehicle paint mixed with Mipa hardener can give you the perfect viscosity needed to make your car paint both durable and attractive. The hardener is a key part of the process of preparing the paint for application to the outer surface of your vehicle. You also need reducer. The process of mixing Mipa paint hardener is the same as with other paint hardeners. The exact ratio of hardener added depends on the type of paint used.

Read the paint instructions to determine the ratio of hardener and reducer to mix. Paint hardeners facilitate the chemical reaction between the paint and vehicle so proper hardness is achieved after drying. Paint reducer works by lessening the viscosity, which is the "thickness" of the paint. The correct mixture is critically important.

Calculate the proper amount of hardener and reducer needed. For example, the paint may call for a 15:15:1 ratio of paint, reducer and hardener, respectively. This means that for 15 cups of paint, add 15 cups of reducer and 1 cup of hardener.

Pour your vehicle paint into a clean mixing container. Add the exact amounts of both reducer and hardener.

Mix the three ingredients using the paint stirrer. Blend thoroughly, stirring at a moderate rate for 10 to 15 minutes, or until the paint colour is completely homogeneous.

Apply the newly blended paint immediately using an auto paint spray gun.

Tip

The perfect ratio of hardener and reducer is crucial, since incorrect amounts can cause problems in both appearance and durability of the paint. When spraying the paint, you will know if you have over- or underreduced your paint. Overreduced paint will be too thin and may leak as it is sprayed on, while underreduced paint will be too thick and not spray at all.
