Can You Paint Waterproof Interior Wall Panels?

Jun 25, 2024

When it comes to interior wall paneling for decoration, painting is a popular choice for changing the design style. However, painting interior wall paneling is typically suitable for traditional wood wall paneling. What about waterproof interior composite wall panels? Can they be painted?

Waterproof panels, such as PVC wall panels or WPC interior wall panels, are made of plastic or vinyl and are designed to protect areas with high humidity, such as bathrooms or garden rooms. In most cases, these composite wall panels can be painted using specific application methods. However, before painting the entire panel, it is essential to test the paint on a small piece of the panel.

PVC Decorative Interior Wall Paneling

PVC, a popular type of plastic often used to create waterproof panels, is melted and shaped to resemble real wood. Manufacturers typically offer a variety of finishes and colors. If you have existing PVC panels and want to change their color, painting them is necessary. Painting PVC plastic is possible, but it requires specific techniques.

Panels Made of HDPE

HDPE is another type of plastic frequently used to manufacture wall panels, using similar melting, molding, and shaping techniques as PVC. HDPE panels are available in various colors and finishes, though fewer than PVC because it is a newer material. HDPE is more commonly used in industrial and commercial settings. If you have waterproof panels at home, they are likely made of PVC rather than HDPE. The painting procedure is the same for both plastics.

Preparation

Preparation is crucial for ensuring a strong bond between the paint and any plastic or waterproof panel. Clean the panels thoroughly with a grease-fighting soap and sand them with fine-grit sandpaper. Wipe the panels down with an acetone solution to remove any dust or grease, then immediately clean the surface with a damp cloth to remove any remaining acetone. Skipping this step will result in poor adhesion, causing the paint to peel and flake off, leaving unsightly bubbles, flakes, and scratches.

Painting

After preparing the surface, you can begin painting. Use plastic-safe paint. Acrylic primers formulated for use with plastic or epoxy primers can be used. Ensure the solution is water-based, not oil-based. Apply the paint with a roller for flat panels or a brush for ridged or grooved panels. Allow 24 hours for the primer to dry.

Once the primer is dry, paint the surface with acrylic paint formulated for use with plastic, which contains ingredients that increase its flexibility. Plastic paint is available in both container and spray forms, both adhering equally well. If the paint bubbles, scrape it off and add paint thinner to the primer. A starting ratio of 5 to 10% thinner to 90 to 95% primer is recommended.
