WHAT IS THE BEST TIME TO PAINT MY HOUSE’S EXTERIOR?
You often don’t have to follow a strict painting schedule for your house. When your house badly needs a fresh lick of paint, you will know because you can see it in the state it’s in. But that doesn’t mean you can repaint right away unless it’s the interior that is looking worse for wear.
The interior of a house is a controlled environment and, as a result, you can paint in almost any weather. Not so for your house’s exterior. To achieve a satisfactory, long-lasting result, exterior painting demands picking the right weather conditions.
As you can’t control the weather, you must choose the season with the most conducive weather for exterior painting. The weather needs to be dry but not too hot.
WHY THE WEATHER MATTERS IN EXTERIOR PAINTING
To understand why weather conditions matter in exterior painting, you have to understand how paint dries and cures. Note that with paint, drying and curing aren’t the same things, though the latter can’t happen without the former.
Paint contains pigments (colouring agents), a resin or binder, and a solvent. While the solvent dilutes the pigment, the resin binds the solution so the solvent and the pigment do not separate. The resin and the solvent, in this case, are the pigment’s vehicle. On its own, the pigment would not stick to what it’s applied.
However, when you apply paint to your wall, you often have to thin it using water or any appropriate solvent to reduce its viscosity and so it spreads easily. Importantly, though, paint needs to dry in order to cure properly. But it shouldn’t dry too quickly or too slowly. This is why picking the right weather to paint in is so crucial.
SUMMER IS THE BEST SEASON FOR EXTERIOR PAINTING
Depending on where you are, early summer or late fall is the best time of the year for exterior painting. This is when the weather is dry enough during the day and the temperature doesn’t fall too steeply after nightfall. High humidity also affects how well paint dries and cures, so pay attention to that as well.
The rule of thumb is to consider the forecasted weather days before and after your intended painting dates. If you paint too soon after it’s rained, the surface may not have dried enough for the paint to properly adhere. The consequences aren’t much better if it rains too soon after you have painted as the paint will take too long to dry and cure, causing it to crack and peel.
Generally, make sure it’s not hotter than 50 degrees Fahrenheit nor colder than 32 degrees Fahrenheit when you paint your exterior walls. But what if you can’t get days of perfect weather to paint in?
Well, a trick when painting in hot weather is to follow the shade. Paint the shaded side of the house first. As the sun rises and drops, so does the shade move around the house. The temperature on the shaded side of the house will be lower than the sunny side, giving you more ideal conditions to paint in.
