The Enemies of Paint

Always check the weather before painting,

Chalky paint, cracking, bubbling, uneven application…if you have ever wondered why this happens it was probably caused by one or more of the “enemies of paint”.

Weather conditions

Weather conditions need to be consulted in applying paint whether it is inside or on the exterior of your home. When JT Painting comes to your home to give you an estimate for your painting project we also give you an estimate on the length of time it will take to complete the work. We will include a discussion of weather considerations in completing the project.

Weather conditions include temperaturehumiditysunlight, and wind.

Applying paint when it is really hot outside will cause the paint to dry too quickly. If the exterior surface is very dried out this will add greatly to the problem. The paint will thicken and become difficult to apply. The particles in the paint will not fuse together properly causing an inferior finish. The finish may look fine but the durability will be affected.

When paint is cold it gets thick. It is much harder to use. Again temperature affects drying and the particulates in the paint will not bond correctly.

Direct sunlight will have a similar effect in that it will heat up the surface and cause the paint to dry too quickly. This is one reason that we often start painting as early as possible. We can follow the sun around the project in an effort to stay ahead of the direct rays of the sun.

In contrast, starting later in the day means that we may be able to paint sides of the exterior that are not in the sun but we will not be painting for as many hours. Paint needs time to dry before the possibility of increased moisture…moisture that the evening cooler hours bring on. Changes in temperature and humidity have a direct effect on paint.

High humidity may cause paint to sag and even run. It will slow down the drying process. Of course, this problem is much worse if the surface is wood. High moisture and water can also be the cause for blistering of exterior paints.

Windy conditions will also affect the drying. Wind removes the moisture from the paint which results in drying too fast. This can affect the long-term durability as well.

All of these factors are true for inside projects as well. Avoid painting in high humidity, and low or high temperatures. Always be sure to have good ventilation. This will help the paint to cure correctly and also allow the solvents that may be released from the paint to dissipate.

At JT Painting we will always emphasize quality. Quality in paint will help in dealing with the problems weather can create. High-quality paints adhere to surfaces better than ordinary paint. Quality paint also contains elements that will reduce discoloration due to weather stress.

And remember if it’s worth painting it’s worth calling a professional…. call or contact JT Painting Services.
