Remove coating by scraping and sanding. Prime and repaint, with a premium water-based paint, and a roller with appropriate nap length. Sanding the surface smooth before repainting with a premium water-based paint can also repair mud-cracked areas.
Premium quality paints have a higher solids content, which reduces the tendency to mud crack. They also have very good application and hiding properties, which minimises the tendency to apply the paint too thickly. Dulux recommends Dulux Wash&Wear®.
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.
