Winter Painting Tips:
Painting the exterior of a home in the winter time is difficult when the snow is falling and the temperature outside is below freezing. There are some new paints that can be applied at lower temperatures. These paints allow painters to extend the painting season. Oil-based exterior paints can also be used in winter temperatures, but will take a long time to dry if it doesn’t warm up.
1. It’s possible to paint in winter temperatures with water-based paint (above 37 degrees), but other materials such as caulking, fillers and primers need warmer weather.
2. Oil-based exterior paint, or an acrylic paint is designed to be applied at temperatures as low as 37 degrees Fahrenheit. When the winter weather is a factor, consider a product like Sherwin-Williams Resilience exterior acrylic paint, which develops a moisture-resistant film in half the time as regular paint.
3. Check the weather forecast. A high of 60 degrees Fahrenheit still means that for most of the day the air temperature will be lower. Paint relies on air temperature for proper drying. Even when it’s 60 degrees outside, the surface temperature may only be 45 degrees.
4. Start working as soon as the weather warms up (37 to 50 degrees). Follow the sun around the house as you work. Stop working when the temperature starts dropping.
5. If dew settles on paint before it’s dried, it will make it patchy or blotchy because moisture will become trapped under the paint film (leading to blistering when the trapped moisture tries to evaporate). Also, allow extra drying time between coats, because cooler weather will slow the drying time.
