Can you paint waterproof wall panels?


Waterproof panels are made of plastic or vinyl and are used to protect areas that are prone to moisture, such as bathrooms or exterior walls. In most cases, strict application methods can be used to paint this plastic. However, before painting the entire wall, all paint should be checked on a small area of ​​​​the panel.

Preparation of paint waterproof wall panels

Preparation is essential for proper paint bonding of plastic and waterproof panels. Panels should be thoroughly cleaned with grease-fighting soap and sanded with high-sand paper.

After that, the panel must be wiped with a solution of acetone to remove dirt and grease. Remove the acetone by wiping the surface immediately with a clean, damp cloth. Acetone left on the plastic can cause adhesion problems.

Ignoring this step will cause the paint to peel off the plastic rather than stick to it, leaving unsightly bubbles, shavings, and scratches on the panel surface.


When the surface is ready, you can start painting. Use paints designed for use with plastics. Acrylic primers designed for use with plastics come in several forms. You can also use an epoxy primer.

Make sure the solution is water-based and not oil-based. Paint can be applied with a roller or brush. Rollers should only be used with flat panels and brushes should be used with panels with protrusions or grooves.

Dry the primers for 24 h. Follow primer application with acrylic paint designed for use with plastics. Generally, this type of paint will have ingredients that make it more flexible. Plastic paints are available in containers or in spray form.

Either way is equally effective at sticking to paint. If the paint foams, remove the paint and mix it with some paint thinner as a primer. 5-10% is a better ratio to 90-95% primer.

Waterproof Wall panels are available in a variety of finishes.

PVC panel

PVC is a common form of plastic used to make waterproof panels. The PVC melts to make it look like real wood. Typically, panel manufacturers offer several finishes and colors. But if you live in a house that already has PVC panels and you don’t like the color, you’ll have to paint the panels. PVC plastic can be painted, but there are a few tricks.

HDPE panel

HDPE is another type of plastic commonly used to make wall panels. Panels are made in the same way as melted, molded and molded PVC panels. HDPE is sold in a variety of colors and finishes. Not as many as PVC, as it’s newer than PVC. HDPE is used more often in industrial and commercial environments. If you have waterproof panels in your home, they are most likely PVC plastic and not HDPE. However, the painting procedure for both plastics is the same.
