National Paints Paints Acrylic Thinner 4L, Multi-Purpose Solvent

It is suitable for thinning acrylic paints and can also be used as a solvent for thinning enamels, alkyds, and oil-based paints. It can serve as an acrylic art medium or aid in reducing viscosity for spraying or brushing across a range of coatings.

The thinner reduces paint viscosity and helps paint level out more smoothly on surfaces. This can lead to fewer brush marks and a more uniform, even appearance in both artworks and painted surfaces.

Begin with small amounts and gradually add thinner until you reach the desired consistency. Typical additions range from a small percentage (5–15%) depending on the paint type, application method (brush, roller, or spray), and desired viscosity. Always mix thoroughly and test on a scrap surface before proceeding with your project.

Yes. The thinner helps reduce viscosity for spray applications. If spraying, ensure proper ventilation, adjust the dilution to achieve the right spray pattern, and follow safe spraying practices.

For a glossy finish, use a low-tack brush to minimize drag. For a textured or more pronounced finish, a coarser brush can be used. The thinner helps you tailor the finish by controlling flow and brush technique.

Treat it as a flammable liquid: use in a well-ventilated area, avoid ignition sources, and wear appropriate PPE (gloves/eye protection) as needed. Store tightly closed in a cool, dry place away from heat or direct sunlight. Keep out of reach of children.

It is designed to be compatible with National Paints products. When using with other brands, test a small amount first to ensure compatibility and desired results.

Acrylic thinner is primarily used to reduce viscosity and improve flow for painting or spraying, while an acrylic medium alters the working properties and finish of the paint (e.g., altering texture, body, or gloss). They serve related but distinct purposes; you can use them separately or together depending on your project needs.

Choose the size based on your project scale and how often you expect to use it. Larger sizes often offer better value per unit, but ensure you can store and use the quantity before it expires. Check the current listings on Fepy for available sizes and pricing.

National Paints Acrylic Thinner is used to thin paints and improve flow for easier application, including spray or brush work. National Paints Acrylic Medium is used to alter the paint’s texture, body, or finish. Use thinner when you need better flow and lower viscosity; use the medium when you want to modify look and feel (e.g., more body, different sheen).
