Hardener
A hardener is a component included in certain types of mixtures. Its properties vary, either by increasing the resistance of the mixture once it sets or by ensuring the product dries properly after application. Use together with our mixing cups and measuring sticks for the correct mixing ratio.

importance of correct hardener amount
The amount of hardener needed in paint depends on the specific product and manufacturer. Typically, the recommended quantity is indicated on the product label or in the technical data sheet. It is essential to follow these instructions carefully, as using too much or too little hardener can negatively affect the paint's performance and durability.
mixing ratio matters
Usually, the required hardener amount is expressed as a percentage of the total paint volume, ranging from 2% to 10% or more depending on the product. Some manufacturers specify a ratio, such as 2:1, meaning 2 parts paint to 1 part hardener. Accurate measurement and adherence to the manufacturer's instructions ensure optimal results. For industrial or automotive paint applications, our mixing cups with pressure scales help you mix paint, hardener, and thinner in precise proportions.
RISKS OF INCORRECT HARDENER USAGE
Using too much hardener can cause the surface to crack and appear unattractive once hardened. Conversely, too little hardener may fail to provide the desired hardness and durability. Choosing the right hardener and amount is critical for a quality finish.
