Weather is a big factor for house painting in San Ramon, especially when doing exterior house painting. It can be tricky, and even a bit risky, if you choose to paint under extreme weather conditions.
You can do house painting during the winter season just as you can paint during the remainder of the year. However, it is better to do interior painting during the chilly months, as snow and precipitation won't affect your job. Exterior painting is entirely different, however.
Doing exterior painting can be more challenging as it is done directly under the weather. It's better to wait until the days start to feel warm again, but if you have to paint, you should expect certain limitations of painting outside during the chilly or rainy weather, which can lead to adverse affects.
Both latex and oil-based paints will be affected by extreme temperatures. Latex paints, since they are water-based, tend to freeze quickly. Alkyd paints on the other hand will become gooey and semi-solid, thus requiring lots of thinning. Despite the presence of paints that are manufactured to stand up to freezing and thawing, their capacities are otherwise limited. So you still need to check your leftover paints (if any) to see if they can still be used. If the paint has some lumps in it or is semi-solid, it is probably because it has gone through several cycles of freezing and thawing. It means that the paint is no longer usable and should be properly disposed of.
Painting during the rainy season is not wise, either. Since the surface will be damp when it rains, any paint added to the surface may have adhesion problems and it will take much longer to dry. The surface may also develop surface problems like bubbling or blistering paint. It is better to wait out until the rain is over and the surface is completely devoid of any moisture to begin painting.
Even if it's not raining or snowing, painting under low temperatures won’t spare you from the following challenges. One of them is slow drying which will likely lead you to do some repainting. Depending on how low the temperatures are and the type of paint you use, drying will take up to six hours. Typically, oil-based paints will need longer drying time.
If you had no other choice but to paint during low temperatures, it is best to do it at certain hours, preferably between 10 AM to 2 PM. Have an infrared thermometer handy -- if it detects that the surface is not that cold any more, then it is ok to paint. Otherwise, you should really delay painting until the season gets warmer.
Painting during very hot weather has issues, as well. Higher temperatures can lead the water in the paint to evaporate which will cause the paint to thicken up. Painting evenly becomes next to impossible with thick paint. The edges of the painted surface will dry causing the roller or brush marks not to flow correctly. Brushes will also clog and the paint will skin over quickly. For anyone painting during hot weather, paint the surfaces that are in the shade and follow the shade around the building. This will help keep you cooler and the paint the right consistency.
Consult paint manufacturers regarding the right type of paint to use under these weather conditions.
