Coastal interiors have a humidity problem too
People expect salt to be an outside issue, but a home a few streets from the beach carries higher humidity indoors all year. It shows up in the same places every time: bathrooms and ensuites, laundries, the backs of built-in wardrobes, and any south-facing room that does not get direct sun. Standard interior paint in those rooms will show mould spotting well before the rest of the house needs attention. So we use mould-resistant systems in the wet and shaded rooms specifically, and keep standard finishes where they are perfectly adequate.
Windows that get opened
Coastal homes live with the windows open, which means salt and fine sand settle on sills, reveals, and tracks. Those surfaces need proper cleaning before painting or the coating sits on grit and lifts at the edges.
Light off the water
Reflected light near the beach is bright and comes in low. It flatters a well-prepared wall and it is merciless on a poorly prepared one. In rooms with a water outlook we usually recommend a low sheen, because higher gloss will pick out every flaw in an older wall.
