Choosing the type of thinner based on the type of job

The first thing to consider in selecting a thinner type is the type of job because each type of thinner is different and not suitable for every job type. 

  • Thinner for cleaning

This is an inexpensive thinner that can be found in general hardware stores. Its properties include dissolving all types of paint and cleaning paint tools such as paintbrushes, spray guns, paint trays. This type of thinner has a high dissolving power.

  • Thinner for wiping off stains

It is used for efficiently wiping off various stains such as clean oil stains, grease, silicone, asphalt, and metal surfaces. It usually doesn’t have a pungent smell, is not irritating the hands, and does not corrode the workpiece’s plastic surface. This thinner is also not suitable for mixing with paint because it does not have enough strength to dissolve the paint.

  • Thinner for mixing paint

This is used to increase the viscosity of the paint and prevent paints from hardening at the bottom of the container when not in use. By mixing those paints with the thinner in the correct proportions, it can reduce the viscosity of the paint and the concentration of the paint, making it easier to apply smoothly and evenly.

Choosing the type of thinner based on the properties
