How Salt Air Affects Paint in Hermanus

Hermanus sits directly on Walker Bay, one of South Africa's most exposed coastal positions. The prevailing south-easterly and south-westerly winds drive salt spray from the surf onto properties throughout the year. Understanding how this affects your home helps you make better decisions about paint products, maintenance timing and budgeting.

Salt Air and Paint Failure

Salt particles are hygroscopic - they attract and hold moisture on painted surfaces long after rain has dried. This moisture works into micro-pores in the paint film, gradually breaking down the bond between paint and substrate. The result is premature chalking, peeling and adhesion failure - paint that fails in three years rather than the seven or eight years it should last with correct product specification. Properties on the cliffs and seafront face the worst conditions.

Metal Corrosion

Gates, burglar bars, window frames, balustrades and roof hardware corrode significantly faster in Hermanus than inland. Annual inspection and immediate touch-up of any chips is essential. See our anti-rust guide for Hermanus homes.
