A rough, crinkled surface can usually be traced to painting in less than perfect weather conditions.
- The surface being painted, or the weather itself, was too hot.
- A freshly painted latex surface was exposed to rain, dew, fog, or other high humidity levels before it could dry.
- A top coat was applied before the undercoat was fully dry.
- A solvent-based paint was applied too thickly.
- Paint was applied over a dirty, waxy, or otherwise contaminated surface.
What to do:
- Remove all old paint by scraping and sanding. Once you are down to the bare wood (or other substrate), prime and then top with two coats of exterior latex paint.
