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.
Failure of the paint to resist absorption of dirt and stains.
Yellowing describes the development of a yellow cast in ageing paint solvent-based enamels.
Wrinkling is a term to describe a rough, crinkled paint surface, which occurs when uncured paint forms a 'skin'.
Sagging is the downward "drooping" movement of the paint film immediately after application that results in an uneven coating.
