Does this paint resist dirt and mould?

Troubleshooting

Paint is not adhering well to the surface.

Ensure the surface was properly cleaned, dry, and free from contaminants. Check if a suitable primer was used on bare or powdery surfaces. The surface temperature may have been too low during application.

Uneven colour or finish.

Ensure the paint was thoroughly stirred before and during application. Check for inconsistent application thickness. Ensure previous coats were adequately dry before applying the next.

Paint is peeling or flaking.

This can indicate poor surface preparation, inadequate primer use, or application in unsuitable conditions (e.g., damp surface). Ensure all preparation steps were followed correctly.

Surface still shows signs of mould after painting.

Ensure all existing mould was removed with a fungicidal wash *before* painting. If mould reappears, treat the affected area and re-apply paint if necessary.
