Thinner and hardener
Hardener and thinner are essential when mixing paint. A thinner is used to adjust viscosity and evaporation rate in putty, paint, primer, filler, or clear coat. A hardener ensures the product dries properly after application and forms a durable, sealed surface. Note that some products require dedicated hardeners and thinners.

when to use hardeners and thinners in paint
Thinner and hardener are two distinct additives that can be mixed into paint if it is designed for them. For two-component products like primer, basecoat/auto paint, or clearcoat, an additional component is needed to complete the product. The hardener activates the drying and curing process, while the thinner adjusts application properties. Always refer to the technical data sheet for exact conditions. Note that thinners and hardeners serve different purposes and are not interchangeable.
CHOOSING AND USING THINNERS AND HARDENERS
Thinner reduces paint viscosity, making it easier to apply, improving flow and leveling, and speeding drying. It is commonly used with oil-based paints and some water-based paints like latex or acrylic, depending on the paint base and desired consistency. Hardener improves paint durability and hardness, especially in automotive and industrial finishes. It must be added to two-component systems just before application, chemically reacting with the basecoat to create a tough, scratch- and chemical-resistant surface. Always follow manufacturer mixing ratios and instructions to ensure optimal results and avoid damage.
