Does sunlight affect paint?

Sunlight contains powerful UV rays that react with the pigments in the paint, slowly bleaching them out. This is most visible in dark or brightly colored paints, as the color will lose intensity slowly.

Is 90 degrees too hot to paint?

Does sun paint cure faster?

Sunlight prevents the paint from drying smoothly. Certain types of paints dry quicker than others, especially latex. When you’re painting in hot, sunny weather, more time is needed between coats. When a second coat is added too soon, the paint may peel off from the moisture collecting underneath.

What happens if you paint too hot?

Too Hot. Heat affects paint adhesion primarily because it causes the paint to dry too rapidly. Temperatures over 90 F can cause paint to bubble and blister, which results in peeling once the paint cures. Allow enough time for the paint to dry to the touch before nighttime temperatures cool enough for dew to form.
