Latex paint bubbling after rain is often due to moisture seeping into the surface before the paint has fully dried. To prevent this, ensure the surface is dry and free from dirt before painting. Opt for a high-quality primer and paint designed for exterior use. After painting, allow sufficient drying time—typically 24 hours—before exposing it to moisture. Additionally, check for and repair any cracks or weak spots in the surface where water might penetrate.
