When exterior paint starts peeling after only a few years, the paint usually is not the problem. The surface underneath is. Paint can only stick to what it touches, and if it touches dirt, chalky old paint, or mildew, it will let go sooner or later.
That is why every exterior paint job we do starts with a wash. Siding, trim, and soffits collect a layer of dust, pollen, and mildew — especially on shaded walls in our humid climate. Washing removes it so the new coat bonds to the actual surface instead of the grime sitting on top of it.
Pressure matters, and more is not better. Blasting siding at high pressure can force water behind it, gouge soft wood, and strip paint unevenly. We use a lower-pressure soft wash with the right cleaner on siding and painted surfaces, and save higher pressure for concrete and masonry that can take it.
After washing, the surface needs time to dry completely before any paint goes on. Painting over damp wood traps moisture, and that moisture is exactly what pushes paint off the wall later. Then comes the rest of the prep: scraping loose paint, sanding rough edges, priming bare wood, and caulking gaps at trim and corners.
It is more work up front, but it is the difference between a paint job that looks good for a year and one that holds up for many.
