iPAINT AND CONTRACT ANSWERS: WHAT ARE OPTIMAL WINTER PAINTING TEMPERATURES?

iPaint and Contract, Inc. | Glen Cove, New York

At iPaint and Contract, Inc. we are often asked when is the last date we can begin exterior paint work. This may not a concern for those that live in warmer climates but here in Long Island, New York the average first Fall frost is November 11-20th. Temperatures at this time can range from as warm as 60 degrees all the way down to freezing. It’s good to know what happens to different types of paint when it gets cold.

Exterior alkyd and oil paints are based on alkyd resins and natural oils so they do not freeze as quickly but become very thick. Latex paints, on the other hand, contain water and will freeze at temperatures below
32°F. Special additives such as ethylene glycol (similar to the glycol used in anti-freeze to prevent engine coolant from freezing) are used to improve freeze/thaw resistance in paints. These solvents help to protect the latex emulsion from being damaged due to freezing.

Each company and product has it’s own rules for optimal winter painting temperature. Behr’s Premium Plus Ultra line is a combination paint and primer that can be applied at winter painting temperatures temperatures as low as 35 degrees Fahrenheit. Likewise, Sherwin-Williams sells Duration, a Long Island favorite, SuperPaint and A-100 Exterior paints that can be applied at 35 degrees. The Resilience line is designed for cold application and to resist moisture, so rain and dew on a 35-degree morning is not a concern.

Other major paint brands offer similar cold-weather paints, but for any cold-weather paint, keep in mind that the winter painting temperature rating applies to the duration of your painting project and at least eight hours of curing time thereafter.Check the manufacturers labels and get you work scheduled by the end of December if possible. Then concentrate on all your interior painting needs until the Spring thaw.
