There are several types of paint and stage categories that need different treatments for efficiency. Whether your paint is lacquer, enamel, epoxy, urethane, powder, or something else, there is nothing wrong with knowing the details of adding hardener to rustoleum paint.
Synthetic enamel includes single-stage paint that does not require a hardener. You can do the paint job without having or using any hardener on it. However, a hardener can be used or added sometimes based on the paint type. For example, acrylic enamel paints require hardeners to be used often to increase durability and performance.
Here you must know the basic differences between enamel paint and acrylic paint to understand the concept of adding hardener in rustoleum paint successfully.

The alternative does not mean the opposite behavior instead of considering the refinishing terms.
The purpose of adding the hardener to rustoleum paints is to promote the drying time faster. The mixing period is a significant aspect of the whole paint job. Adding too little or too much than required can create unwanted dry patches, sags, and runs in the paintwork.

Make sure that the paint and reducer belong to the same manufacturer before mixing them up. As we mentioned earlier that hardener is being used for faster drying moments. It increases the paint adhesion and brings good results in the future.
Nothing is expected to appear more or less than average. Hardeners also follow the path as it can create disturbance if the mixing ratio gets inaccurate. Multiple defects can take place if too much activator is being used. Excessive heat can occur crack or other imperfect situations due to its nature and also the humidity impacts.
