A summer day may seem like the perfect time to paint your home’s exterior, especially with the sun shining, warm temperatures, and no sign of precipitation in the sky. However, too much heat and humidity cause numerous issues, affecting the quality of a paint job. The ideal painting conditions range between 50 to 70 degrees Fahrenheit. Just as you would avoid painting in freezing temperatures, you also want to steer clear of painting in intense high temperatures. Here are some of the effects of warm weather on exterior paint.

Water to Solvent Ratio

With heat often comes humidity. In warm, humid climates, houses begin to sweat from the moisture lingering on their surfaces. When painting in such weather conditions, the water perspiring from the humidity onto the walls blends with the paint solution. Since paint consists of a chemical mixture consisting of part water and part solvent, the added water causes an imbalance in the paint mixture’s ratio, affecting its quality. Watered-down paints contain less pigment and increase the chances of streaks. Plus, moisture also affects the paint properties within the solution, such as waterproofing additives and specialized sealants.

Cures and Adhesions

Low humidity and high heat levels also affect an exterior paint job. In high temperatures, paint dries faster. Although sped-up drying times sound like an advantage, it actually has negative repercussions. The faster the paint dries, the less effective the binders, cures, and pigments react and interlock. It increases future peeling and cracks and dulls the paint’s color. Usually, the wait time for the paint to dry allows the chemicals in the paint to react and settle. If they dry too fast, the paint doesn’t get a chance to situate and undergo its necessary chemical reactions properly.

Paint Lap Marks

Paint lap marks occur for numerous reasons, from improper paint application to poor paint quality. It also commonly occurs when you paint in warm weather. Paint laps refer to the discoloration and lack of sheen on a paint job. These marks occur when wet and dry paint layers overlap and dry quickly during application. They leave streaks and unleveled surface marking, affecting the appeal of your home’s exteriors.
