Planning To Paint the Exterior of Your Home? Why Autumn Isn't the Best Time To Do It
Posted on: 29 March 2016
Painting can be an easy task, especially if you have the right tools and follow the right procedures, which means you may not even need a painter, especially if you are a DIY lover. DIY painting can help you save a buck, but only if you do it the right way. Among the major concerns when painting is the weather and you will want to pick the most appropriate time or season to paint your exterior house of structures. While autumn might seem like the most suitable time to do your painting because it's neither too humid nor too hot, you just might be making a huge mistake. Below, you will find out why.
Durability
Typically, exterior paint that's applied in the ideal weather conditions should last for a given predetermined period depending on the brand or manufacturer. However, you may find your exterior paint flaking, cracking, or peeling off long before this period if you do it in autumn. Poor bonding and drying of the paint are usually the main causes of paint failure.
The drying and bonding of the paint involves two processes. Fist, the latex or oil in the paint has to dry up as the paint dries. Second, the bonding often involves a chemical reaction that facilitates the adherence of the paint to the surface. These two processes often require warm temperatures and that's why most manufacturers will prefer specific temperatures. However, in autumn, the daytime temperatures may go higher the required or specified temperatures and become lower at night. These low night temperatures will interfere with the chemical reaction required for effective bonding and adherence of the paint to the surface.
Inconsistent Drying Pattern of Caulk and Primer
The difference between the highest and the lowest temperature in the autumn can be higher than that required for exterior painting. This higher-than-normal difference in temperature can lead to inconsistent drying of some of the major paint components such as caulk and primer. These components may therefore not dry at the required/optimum temperatures, meaning that you are likely not going to get the finish of your choice.
Putty Drying Problems When Painting Around Windows
When painting around windows, you may want to add some putty to places where the putty might have been destroyed. Putty usually does well in warmer temperatures or temperatures recommended by the manufacturers. The autumn temperatures may go higher in the day and lower than these recommended temperatures in the night. This means that the putty may take longer to dry, especially during the night and can start cracking. If you paint over an uncured putty, moisture escaping from this putty will pass through your paint coat, meaning you won't achieve the desirable results both of the putty and paint.
