Have you recently attempted to paint your bathroom using Dulux paint, only to find that it's not sticking to the walls? You're not alone. Bathrooms present unique painting challenges due to their high moisture and humidity levels. But don't despair, we've compiled a comprehensive guide to help you understand why Dulux bathroom paint might not be sticking and how you can troubleshoot this issue.
Why Dulux Bathroom Paint Might Not Be Sticking
Dulux bathroom paint is specifically formulated to withstand the rigors of a bathroom environment. However, there are several reasons why it might not be sticking:
- Surface Preparation: Inadequate surface preparation can lead to paint not sticking. This includes not cleaning the surface properly, not removing old paint or wallpaper, or not allowing the surface to dry completely.
- Moisture and Humidity: Bathrooms are prone to high levels of moisture and humidity, which can affect the adhesion of paint. If the paint is applied to a surface that's still damp or in an environment with high humidity, it might not stick.
- Paint Application: The paint might not be sticking due to incorrect application. This could include applying the paint too thickly, not allowing each coat to dry properly, or not using the right paint roller or brush.
- Paint Age: If the paint has been sitting in your garage or shed for a long time, it might have deteriorated and not stick as well as it should.
Troubleshooting Dulux Bathroom Paint Not Sticking
Check Your Surface Preparation
Before you start painting, ensure the surface is clean, dry, and free of any old paint, wallpaper, or dirt. Use a suitable primer to seal the surface and improve paint adhesion. Dulux offers a range of primers specifically designed for bathrooms.

Control Moisture and Humidity
Before painting, ensure your bathroom is well-ventilated and the walls are completely dry. You can also use a dehumidifier to reduce the moisture levels in your bathroom. Once you've started painting, avoid using the bathroom or running water while the paint is drying.
Check Your Paint and Application Technique
Ensure you're using fresh Dulux bathroom paint and not paint that's been sitting around for a long time. When applying the paint, use even strokes and allow each coat to dry completely before applying the next. Use a high-quality paint roller or brush to ensure even coverage.
