Model Paint Thinners
Browse model paint thinner for preparing acrylic, enamel and lacquer paints used in scale modelling. The correct thinner can help adjust paint for brush or airbrush application, but compatibility is essential: always match the thinner to the paint type and follow the paint manufacturer’s instructions.
Use the products above to compare acrylic thinners, enamel paint thinner, lacquer thinner, retarders and related paint additives. Check each product description carefully, as products in this category are not necessarily interchangeable.
Choosing the Right Thinner for Model Paint
Start by identifying the exact paint range you plan to use. Paints described as acrylic, enamel or lacquer can require different thinners, and compatibility should not be assumed from the general paint type alone. Where possible, select the thinner recommended for the particular manufacturer and range.
Acrylic Paint Thinner
Acrylic paint thinner is formulated to adjust compatible acrylic model paints. It may be used to prepare paint for spraying or alter its working consistency, depending on the individual product. Not every acrylic thinner works with every acrylic paint, so check both labels before mixing.
Water should not automatically be treated as a substitute for a dedicated acrylic thinner. Some paint ranges may permit it, while others require a compatible product to maintain the intended behaviour of the paint.
Enamel Paint Thinner
Enamel thinner is intended for compatible enamel paints and may also be sold for specific enamel-based techniques. Choose a product approved for the paint or application you are using. Do not mix enamel thinner with acrylic or lacquer paint unless the manufacturer explicitly confirms compatibility.
Lacquer Thinner
Lacquer paints require an appropriate lacquer thinner. These products can differ in formulation and intended use, so check whether the selected thinner is suitable for your particular paint range and application method.
Thinning Paint for an Airbrush
When preparing model paint for a sprayer or airbrush, the required consistency can depend on the paint, airbrush setup and working conditions. Follow the paint manufacturer’s starting guidance rather than relying on one universal thinning ratio.
- Mix the paint thoroughly before adding thinner.
- Add only a small amount at a time.
- Test the mixture on a spare surface before painting the model.
- Adjust only within the manufacturer’s recommendations.
- Use a suitable cleaner after painting; thinner and cleaner are not always the same product.
Thinners, Retarders and Flow Improvers
A thinner changes paint consistency. A retarder is intended to slow drying, while a flow improver is intended to alter flow characteristics. Some products combine more than one function, but this should be confirmed from the individual listing. Choose according to the paint manufacturer’s guidance and the result you need.
