When fresh paint gets wet right away, a few things can happen. Mostly the issues are solved by simply applying another coat of paint with no other durability issues. With both surfactant leaching and wetting, a simple extra coat will result in a coating with the same durability and appearance.

1. Surfactant Leaching
Scientific advancements in the paint industry have resulted in heavier use of surfactants in paints. These surfactants can come through and settle on the surface instead of through the paint coating like it is designed to. Surfactant leaching is usually the result of cool and humid conditions. However thinning the paint in a cool setting will cause the same surfactants to rise to the visible outer shell of the paint film.
Wetting happens in hot and humid conditions. Paint “wetting” is lighter area of the paint film that got wet. Generally when the paint gets wet again the paint returns to the lighter color and darkens as it dries each time. Sometimes the paint can get permanently lighter.
Blistering can be provoked by wetting and surfactant leaching and the humid conditions. You all know what a blister looks like right? If it happens on your paint, your in trouble. Basically you need to fix the underlying problem, then sand down the blister and fill with appropriate patching materials.
4. Total Mess!
If your paint gets rained on before it even tacks up, don’t panic! You’ll see the paint running down your home and possibly down some brick, stone or other areas that it shouldn’t. If the paint is making a mess then you’ll need to spray it off completely with a hose(yes, in the rain) until its a clean surface and paint it again. Good Luck!
