The optimum time of year to paint the outside of a home is a commonly asked question. Temperature is a major factor.
For a minimum of 24 hours, most manufacturers prefer temperatures below 90 degrees and above the mid-thirties. An incomplete cure can be prevented if paint freezes before drying completely.
Even after the surface has been coated, water can seep into the paint and cause bubbles.
Therefore it is best not to paint when the chance of rain is above 30-40% for the next 24 hours.
Sadly, many painting contractors do not follow this rule. As a result, they prioritize speed above quality when working on any given project.
Keeping an eye out for weather conditions is one of the things we do since we give guarantees on our outside painting work.
