Ideal Temperatures For Painting A House

Table of Contents

So, you want to paint your home?

 

Should be simple, right? Clean it down, remove the old paint, and apply the new. Job done!

 

Well, not so fast. Have you thought about the ideal temperature for painting a house? Sure, you probably know not to paint when it is raining or snowing, but slight changes in the temperature can affect the finished product. Let’s take a look at what you should know. 

Minimum Temperature

You want to make sure that the temperature is at least 50 Fahrenheit when you are painting. Not only is this going to ensure that you are not too cold when you are painting, but it is also going to help the paint to cure. When the paint cures it forms a more effective barrier against the elements. 

 

Now, when you are thinking about minimum temperatures, you also want to look at the days that proceed painting day. The temperature should not drop below 32 Fahrenheit, even at night, or dew drops can form on the paint. This extra moisture can stop the paint from properly curing. 

 

The result could be cracking, peeling, mold, and mildew. 

 

Plan a painting day that is not too cold, and make sure that the next few days do not get too cold either. 

Maximum Temperature

Generally, it does not matter how hot it is outside as it will not affect the quality of the finished job. Of course, that does not mean that you should paint in any heat.

 

The first thing to think about is your own health and comfort. Being outdoors, exposed to the elements, in extreme heat, can lead to heatstroke, dehydration, and more. The first step to choosing the appropriate temperature is to decide on a day that is comfortable for you to paint in. 

 

If you are not sure, then you can check the heat on the side of your home. Place your hand on an exterior wall and hold it there. If you cannot hold your hand there for more than a few seconds, then it is too hot to paint and you should choose another day. 

 

While we do not state that there is a maximum temperature to follow, be aware that paint will dry quicker at higher temperatures. When it is extremely hot, and depending on the type of paint that you are using, this can make it difficult to paint effectively. 

Follow The Instructions

Our recommendations are a rough estimate. Most paints will be fine to apply as long as the temperature is over 40 Fahrenheit and there is no heatwave. But, that does not mean that every paint imaginable is going to fall within that range. 

 

We always recommend that you default to the instructions. 

 

Before you start painting, check the instructions on your paint can and check for the applicable temperatures. Whatever is stated on the side of the can is what you should follow. 

Follow The Shadow

When you are painting, you want to ensure that you do the best job possible.

 

We recommend following the shadow as the sun moves through the sky. 

 

Start in the most shaded part of your home and paint there. Not only will that stop the paint from drying too quickly, but it will also be better for your health. If you can keep out of direct sunlight, you are going to stay hydrated and protect yourself. It is going to be more comfortable too, and that is going to help you stay efficient. 

Best Time To Paint

Summer seems like a great time to paint, but it can get hot. 

 

Based on the information above, we would recommend painting either in spring or fall. It is going to be not too hot and not too cold. 

Final Thoughts

 

Choosing the ideal temperature to paint your house is as much about protecting yourself as it is about protecting the exterior of your home. 

 

Be sure to plan for a day that is not going to be too hot or too cold, but also check the days that come after and make sure that the paint has enough time to cure. 

 

Stay safe and paint efficiently.
