Feb 28

You've probably heard that you can't paint in cold weather. However, how much of this is true? While taking on an exterior paint job during the cooler months has its own set of challenges, Toronto Home Painters beleives it is certainly doable.


Whether a winter storm damaged some of your home's exterior paint or you simply want to get a head start on the new house colour, painting in cooler months with the right materials and precautions can be just as effective as painting on a warm spring day. Continue reading to learn how to paint the outside of your house safely in cold weather.


Painting the Outside in Cold Weather

It is common knowledge that exterior painting can only be done in the summer. These Toronto Exterior Painting pros insists this is a common mistake when it comes to exterior painting. Exterior painting in cold weather can be difficult but not impossible in a climate with changing seasons. You can use the cooler months to finish exterior painting projects so you can relax and enjoy the beautiful summer days. So, with the proper knowledge, exterior painting in cold weather is possible.


What Effect Does Cold Have on Painting?

When temperatures fall below 50 degrees Fahrenheit, the paint and application process can suffer. But why is this so?

Oil-based paints are primarily composed of oil and resins, which thicken at lower temperatures. This makes trying to paint a smooth application difficult.

Water-based paints are commonly composed of latex and water, which increases the risk of freezing significantly. This can interfere with colour consistency and the bonding process.

To cure, the chemicals in these paints must be exposed to a specific temperature range. Improper exterior painting curing in cold weather can result in premature chipping, cracking, peeling, or a low sheen.


Is it possible to use previously frozen paint?

Chemicals are present in all paints. That is what gives us the sheen and brightness of a freshly painted surface. The chemical structure of the paint changes dramatically once it has frozen. Water-based paints are typically the culprits of freezing, and once this occurs, they should be left alone for your next painting project, whereas oil-based paints take longer and colder conditions to freeze.

Using previously frozen paint can cause the paint to not cure at all, resulting in an inconsistent, blotchy mess whether used for exterior painting in cold or warm weather. It is always best to keep your paint in a non-freezing location so that you can reuse it in the future.


Exterior Painting Tips for Cold Weather

Gold Painters which is one of the best painting companies in Toronto has outlined some of the best tips to remember when tackling exterior painting in cold weather include:


Choosing the Best Exterior Painting Temperature

The answers can differ slightly depending on who you ask. Professionally speaking, Toronto House Painting experts knows that temperatures should be at least 50 degrees Fahrenheit and no lower than 35 degrees Fahrenheit during the night. This formula provides even coverage and a lovely sheen to your paint job.

You should choose a time when there is no rain in the forecast and little to no wind. Some people believe that the sun is required for the paint to cure properly, but this is a myth as long as the temperatures and humidity levels are maintained.

On the other hand, there are times when it is simply too hot to paint outside. Many of the same negative effects that painting in the cold can cause can be seen when the weather is too warm.

The bottom line is that paying attention to the manufacturer's label on paint products is critical for determining the best time to apply the paint for the best results. In some cases, having patience is preferable to doing the job again.


Wrapping Up the Ins and Outs of Cold Weather Exterior Painting

Is it worthwhile to try exterior painting in cold weather? Yes, it is possible. However, there are some conditions. It is best to find an exterior paint that can withstand cold temperatures and maintain specific temperatures long enough for the paint to cure. If this does not occur, you will be left with a paint job that will most likely need to be repaired or completely redone.

Remember that surface temperatures also play a significant role in this. Just because the air temperature has reached the minimum curing point does not mean you are ready to start working.
