A Simple Guide to Finding the Best Temperature to Paint Outside

Best Temperature To Paint Outside | Ideal Exterior Painting Temperatures

Are you planning to kickstart your exterior home painting? Have you checked the weather forecast for the day? You must keep in mind the temperature before you start your painting project. This is because the temperature is an important factor that can make or mar your painting work. 

We all know that you must avoid painting your home exterior when it is raining cats and dogs. Similarly, you must avoid painting when it is too hot or too cold as it affects the curing time, adhesion and shelf life of your exterior paints

Wondering when is the right time to paint your home exterior? Here is a comprehensive guide that will tell you everything you must know about choosing the perfect time to paint your home exterior.

How humidity affects painting? 

High humidity means that there will be too much water vapour in the air which will increase the time it will take for your paint to cure completely. You must always ensure that your paint has dried off completely before you apply the second coat. If you are painting in a hot and humid environment, then there is a high probability that your paint will form air bubbles, especially if you are using Latex exterior paints. Remember to avoid popping these bubbles because they will disappear on their own. This is because Latex paints tend to expand and contract when exposed to extreme weather conditions. 

Another reason why you must never paint when the weather is too humid is that water vapour and high humidity serve as a conducive condition for mould and mildew growth. 

Painting in hot weather 

If you are using Latex paints, then you must never paint when it is too hot outside. This is because Latex exterior paints dry out quickly and this will make it difficult for you to get a professional finish. Painting experts recommend homeowners not paint in temperatures above 90 degrees Fahrenheit. 

It is believed that the ideal weather to paint your curb is when the temperature is moderate and not too windy. The ideal temperature to paint your outdoors is between 60 to 85 degrees Fahrenheit. Paint experts say that fall or spring are the best seasons to paint your outdoors as the weather is just perfect, not too hot and not too cold. 

Painting in cold weather 

Experts say that you must never paint your home exterior when it is below 50 degrees Fahrenheit. If you are using oil-based paint, then it will thicken in winter, and this will cause your paintbrush to stiffen. Your application will be thick which means that you will be requiring more paint than usual to paint your exterior walls. Painting in winter is also a disaster as the paint doesn’t cure quickly in the winter. This means that you will have to wait at least a day for the paint to dry before you apply the next coat. 

How to prep your walls before you paint?

Just like in the case of interior walls, you must prep your exterior walls before you paint them. Prep your surface. Cover your air conditioner, vents plantings and shrubs to make sure that they don’t get splattered with paint. Thoroughly scrub your walls, remove mildews, patch the holes and dents in the walls, and caulk and prime your walls before you start your painting work. 

Keep in mind that paint brands often mention the ideal temperature for a certain paint on the back of the paint tin. So, make sure to check that and paint accordingly.
