hot sun on a summer day

Painting in the Summer with Liberty Builders

The summer is when most people want to take care of exterior home maintenance duties, like repainting their house. However, extreme hot weather like the type we get down here in San Antonio, is not beneficial to your paint job. Weather has a significant effect on your home’s exterior. As the days get warmer, the sun will have an impact on your home’s paint job among other things.

Humidity and heat have an influence on the time it takes your paint to dry. Don’t paint in the sun when it’s hot outside. Painting in the heat of the sun is not recommended because the paint will dry too fast. This may lead to lap marks, which happen when you paint large areas and it dries too quickly. This leaves striations, a series of ridges, furrows or marks, on the surface, and will ruin the paint’s appearance. Paint in the early morning when it is less hot and allow for double the drying time the paint label states. Also, paint in small sections and not large ones for the best results.

Painting in the damp, rainy environment is not any better than painting in the heat. If you’re having a wet summer (which could be rare for San Antonio), you are bound to fail if you paint over any wet surface. When you paint over a wet area, you seal in moisture and enclose it. When the sun hits the area, it tries to dry the moisture out, causing the paint to life and ruining the paint job. If you’ve ever seen peeling paint, this is a big sign of that. To make sure you’re not painting on a moist area, use a hygrometer to measure the amount of moisture on the exterior surface of a house. For best results, paint on a dry, warm day.
