How to prevent peeling paint
Water repellent preservative is the all-time-kept secret in the world of painting. Decades of university and regime studies have shown that WRP adds years to the life of an exterior paint job. Merely almost painters—pros and DIYers akin—have never heard of it. Here's how it works:
Peeling often begins with a tiny crack in the pigment. A little water sneaks in and the woods swells, stretching the pigment and causing more cracks. Then, as the water evaporates, it pushes confronting the pigment from behind. Each fourth dimension this cycle occurs, the crack grows and the paint bond weakens. It doesn't take long before a minor crevice becomes major peeling.
WRP prevents this cycle. Applied to bare woods before priming and painting, information technology keeps wood from absorbing h2o afterwards the paint cracks. And that delays peeling. It's merely that simple.
Finding the correct WRP isn't so elementary considering some are paintable and some aren't. The labels don't ever tell you, and the shop employees won't have whatsoever thought what you're talking nearly. And so I contacted a few manufacturers, talked to the guys in lab coats and found some widely available WRPs that are paintable. Here'southward a list:
