Temperature plays a key role when it comes to painting the interior or the exterior of the house. Since we can maintain the interior using the HVAC system, it won’t be problematic for us to paint it whenever we want. However, the exterior is nature controlled, so we will have to be careful when painting it; otherwise, the wrong temperature can cause the paint to chip away or have a lower lifespan.
So to help you understand how paint is affected by the temperature, what should be the ideal temperature for painting, and the things you need to remember when painting in hot or cold weather, we have created this guide. And we hope by the end of it, you will be a savant in choosing the temperature correctly. So with that said, let’s dive right in:
If you paint your home in a hot temperature, then the heat will make it dry rapidly. Plus, it will also affect its adhesion to the surface of the wall, which means the paint just won’t stick. When the temperature goes over 32 °C or 90 °F, then it starts to form blisters and bubbles, so once the paint finally cures, it starts to peel off.
As for the cold weather, when the temperature goes below 12.8 °C or 55 °F then it becomes too cold for the paint affecting its speed of curing. This is also not ideal because now the paint will take longer to dry, and all the dust, dirt, and grime will be attracted to its surface and get stuck in it.
Furthermore, surfaces that are improperly cured will have a higher tendency to chipping and cracking, plus, cold temperature affects the overall life of the paint as well. If you are using oil-based paint, you should know that it gets thick in cold temperature, which means brushing will be stiffer, application with be heavier, and you will be getting less coverage for each gallon.
The best paint temperature depends on the type of paint you are using and also whether the place is covered or not. Since we are talking about exterior painting, so let’s just directly discuss the ideal temperatures for painting outside. So according to most of the paint manufacturers, following temperatures should be good enough:
If the temperatures are way lower than the ones mentioned above, then you can get the specially formulated latex paint, which is made to perform in low temperatures. Also, make sure to take humidity into account when painting, too much humidity can result in longer drying times and also discolouration of paint. We suggest you run dehumidifiers in the area before painting.
Your house’s exterior plays a critical role in its overall curb appeal. The better you paint it, the more it will attract attention and also add to its financial value. So we suggest you choose the time of the year for painting the house very carefully when the temperature is optimal and get the job done fast.
