Failure of the paint to resist absorption of dirt and stains.
Use of lower quality paint that is porous in nature
Application of paint below the recommended film build, often the result of painting over an un-primed substrate
Higher quality water-based paints contain binders that have been formulated to help prevent stains from penetrating the painted surface, allowing for easy removal.
Priming new surfaces reduces porosity, and therefore, ensures maximum film thickness of a premium top coat, providing very good stain removability. Dulux recommends Dulux 1 Step® Acrylic Primer Sealer & Undercoat and Dulux Wash&Wear® for stain resistance properties.
