Polyurethane

This is a popular choice for sealing MDF crafts as it offers a durable and waterproof finish. It is available in both oil-based and water-based formulas with varying levels of gloss.

Polycrylic

For a non-yellowing and crystal-clear finish, polycrylic is an excellent choice. It is easy to apply and dries quickly, ideal for lighter colours. This finish works especially for internal doors without compromising indoor air quality.

Varnish

Tips for a Flawless Finish on MDF Spray Painting

Sand Between Coats

Lightly sand the MDF between each coat of primer, paint, and finish to achieve a smooth and even surface. It removes imperfections like brush marks and dust nibs while helping the next layer adhere better.

Invest in good-quality brushes and rollers to avoid streaks and brush marks. For MDF spray painting, opt for even and sweeping motions to prevent drips. If you are working on exterior decorating, these tools will help you achieve a more refined and professional look with less effort.

Allow Proper Drying Time

Apply multiple thin coats of paint and finish instead of one thick coat to avoid drips and ensure an even application. You also need to make sure that each layer is completely dry before applying the next to avoid smudging and ensure a durable finish.
