Springtime is the best time to give a home a fresh coat of paint, according to the Paint Quality Institute. “By painting in moderate weather, you’ll likely get a longer-lasting paint job,” says Debbie Zimmer, paint and color expert for the Paint Quality Institute. Zimmer says that exterior painting is best to do when temperatures are above 50 degrees Fahrenheit, but not when it gets too hot. “Very hot days can cause the paint to dry too quickly and impair good paint film formation,” she notes.
Some more tips for exterior painting:
1. Paint in the shade and avoid painting in direct sunshine. Sunlit surfaces can be 10 to 20 degrees hotter than the air temperature.
2. Don’t paint when it’s too windy. Wind can cause latex paint to dry too quickly as well as cause dust and other contaminates to imbed in the paint, possibly creating a surface ripe for mildew.
3. Avoid the rain. Wait for another day if it’s rained within the last 24 hours. If several days of rain is forecast, postpone your painting for several days until a rain-free week.
4. Prime the surface. Apply a coat of primer to any new surface that has never been painted, or spot-prime areas where paint has worn away.
5. Don’t skimp on paint. Use top quality 100 percent acrylic latex paint. It’s durable, flexible, colorfast, and can often last 10 years or more compared to ordinary paint, Zimmer says. To make the paint last even longer, apply at least two coats–a coat of primer and coat of paint, or two coats of house paint.
6. Don’t postpone painting. Postponing painting the exterior of a home that is long overdue can actually cause damage to a home. Exposed wood can begin to rot and other types of exterior siding also can suffer when the paint starts to wear off.
