What matters for project planning
Salt and sun are the whole story for coatings here, and they act together. Airborne salt settles on surfaces and holds moisture against them, which is why washdown before painting matters more on the coast than inland and why a finish that lasts eight years elsewhere may not here. Wind-driven rain finds any gap in preparation. In a local historic district, review can reach color and material on anything visible from the street — and on the older downtown stock, what is under the current coating decides the preparation far more than the product chosen decides the result.
