How Warm Weather Affects Exterior Painting

When painting the exterior of your home in warm weather, you want to be sure that you’re using the right paint for the job. The surface of your home should be clean and dry before applying any paint. It is also important to use a paint sealant when you are painting the exterior of a house.

Too much heat can cause cracks in your paint job and can also lead to peeling or blistering. The best time for painting your home is between 50 and 70 degrees Fahrenheit. If you are going to be painting in temperatures above 70 degrees Fahrenheit, it is best to hire a professional painter like us here at Dependable Painting & Remodeling who has experience with this type of project.

Using the wrong type of paint can also cause issues when painting your home’s exterior in warm weather. For example, if you are using an oil-based primer on an asphalt shingle roof, it will cause the paint to bubble and peel off easily during application.


Paint Thinner Can Be Flammable

When it comes to exterior paints, light-colored latexes are best suited for warm summers and summertime is the best time to paint the exterior of your house.

However, these paints tend to thicken more than other types when exposed to warm temperatures and humidity levels.

This can lead to cracks or peeling in certain parts of your plaster molding or stucco surface if left untreated by applying a latex thinner before painting.

A thinner is a water-based solution that helps remove excess latex from your walls so you can apply fresh paint without much trouble or risk of cracking or peeling during application.

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, the 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.

The amount of time it takes for your exterior paint job to completely dry will depend on several factors: how much moisture is present in the air; what kind of surface you have (e.g., wood vs. asphalt); how warm it is outside; how hot it is outside; etc…
