A reducer is sometimes required when a paint needs to be thinned. This is common when the paint is applied via spray equipment, or for cleaning up. The rule of thumb is to reduce as little as possible. It is recommended to try the paint without a reducer first and thin up to 10% as needed. Our Acrylic Enamel paint must be sprayed and can be reduced using Normal Butyl Acetate or Acetone. When you place an order with MyPerfectColor, you will automatically receive an email with technical instructions on how to use the paint. This will include the need for a reducer and the type of reducer to use.
