Yes, you can paint a house exterior in November in Ohio, if the paint is rated for the cold and the weather gives it time to cure. The answer is printed on the product data sheet, not the calendar. Several premium exterior paints from Sherwin-Williams and Benjamin Moore list 35 degrees as their floor. That's half the rule. The other half is what happens to the wall after the sun goes down.
Wells Painting paints house exteriors out of New Richmond, and our exterior house painting carries a three-year warranty.
Can you paint an exterior in November in Ohio?
You can, with the right product and the right stretch of days. Sherwin-Williams says as much in its own exterior FAQ: until a few years ago you needed to paint above 50. Its newer products, like Duration and SuperPaint, moved the line to 35.
One forum poster put the old view flat: "The paint won't stay on if you paint it now anyway." For the paint they had, they were right. With a can rated to 35, the question changes. It's not "is it too late in the year?" It's "will the air, the wall and the paint stay warm and dry long enough for this coat to cure?"
What the paint can says, product by product
These numbers come from each manufacturer's current product data sheet. Read the sheet for the exact product and sheen you're buying, because they change. Benjamin Moore's 2021 sheet for Aura exterior satin said 40 degrees. The current one says 35.
Sherwin-Williams Duration, Emerald and SuperPaint Exterior
- Air, surface and material temperature above 35 degrees, and at least 5 degrees above the dew point.
- Don't apply when air or surface temperatures may drop below 35 within 48 hours.
- Avoid it if rain or snow is expected within 2 to 3 hours.
- Recoat time at 35 to 45 degrees and 50% humidity: 24 to 48 hours. At 45 and up: 4 hours.
All three sheets (Duration satin, Emerald flat, SuperPaint flat) print the same temperature and dew point rules.
Benjamin Moore Aura Waterborne Exterior and Regal Select Exterior
- Minimum air and surface temperature: 35 degrees (Aura satin N631, Regal Select low lustre N401).
- Dry to the touch in 1 hour, recoat in 4 hours, measured at 77 degrees and 50% humidity.
- Both sheets say high humidity and cool temperatures will result in longer dry, recoat and service times. Neither prints a dew point number.
The primer under it
Sherwin-Williams' exterior sheets also say standard latex primers can't be used below 50 degrees. If bare wood on your house needs primer, that label may set a higher floor than the paint does. The warmest-rated product in the system decides the day, not the coldest.
When does Cincinnati get its first freeze?
The National Weather Service office in Wilmington publishes fall freeze dates from 1991 to 2020 data. For Cincinnati, the normal first 32-degree night is October 25. One year in ten it comes by October 12. Nine years in ten it's come by November 5. The full table is on the NWS Wilmington fall freeze page.
The first freeze isn't the end of exterior season. Days after it can still be warm and dry enough to paint. What bites in late fall is the night after you paint, the dew at dusk, and how few dry hours a November day gives you.
The same NWS page notes official temperatures are read five feet off the ground. On a frosty fall night, five feet may read 36 while the ground is at 32. Siding near your foundation lives closer to the ground number than the forecast.
Why paint that went on fine at noon can fail overnight
Latex has to melt together
Latex paint is tiny resin particles in water. As the water leaves, the particles have to fuse into one film. That's coalescence. Sherwin-Williams' FAQ says warmer temperatures are needed for the particles to melt together, and the paint can stop coalescing when the temperature drops. Dry to the touch isn't the same as cured.
Dew lands on fresh paint
Sherwin-Williams puts it plainly: dew forms on almost everything as soon as the sun goes down, and it can seep into uncured paint. Most products need at least 4 hours of dry time before moisture settles on them. Ideally, the FAQ says, the temperature stays in range and above the dew point for 48 hours after you paint. The mistake it names: painting when days rise above 50 and nights drop below 35.
The wall is colder than the air
The Duration sheet says it directly: when the air is at 35 degrees, substrates may be colder. A forecast high of 52 doesn't tell you what the clapboard is at 9 in the morning.
North walls and shaded walls
A north wall, or one under big trees, gets little or no direct sun in November. It stays colder and damper, and morning dew can still be sitting on it at noon. The USDA Forest Products Lab notes mildew is most common in shaded, moist, or protected areas. Those walls are also the slowest to dry a fresh coat.
Sun-facing walls after dark
The south and west sides hide the opposite problem. At 2 in the afternoon that wall feels warm and the paint flows well. Once the sun drops, it cools and catches the same dew as everything else. A coat put on late in the day gets the shortest run of warm, dry hours.
Short days
In November the morning dew is slow to burn off and the evening dew comes early. Take the 4 dry hours before moisture, add time for the wall to warm up, and the window on each side of the house gets small. Sherwin-Williams says it in one line: the cooler the temperature, the sooner you should stop painting.
What late-season paint failure looks like
Sherwin-Williams lists what can happen when fresh latex gets cold or wet before it cures: surfactant leaching, mildew growth, frosting, and adhesion problems. Dew in uncured paint can stain the surface. Dark colors can turn white or frosted looking when latex goes on below its rated temperature.
Adhesion is the expensive one, because it doesn't show the next morning. It shows after a winter has worked on it. That's why the 48-hour forecast matters more than the hour you're painting in.
What you can do if fall runs out
If the forecast won't give a clean stretch of days, you have two good options. Get your exterior house painting estimate now and set the start for spring, with color and prep settled before the weather turns.
Or move the project inside. Cold months are a good time for interior painting in your rooms and trim, and that work doesn't wait on dew.
Denny is on every job, and the same crew that preps your house paints it. Sherry S. wrote that "The owner actually came to the house months later to make sure everything looked good." You can read more on our customer reviews page.
Questions about late-season exterior painting
Can you paint a house exterior in November?
Yes, with a paint rated for low temperatures and a forecast that cooperates. Duration, Emerald and SuperPaint exterior data sheets say above 35 degrees, at least 5 degrees above the dew point, and no drop below 35 within 48 hours. Aura and Regal Select exterior sheets list 35 degrees for air and surface.
Is it too late to paint outside after the first frost?
Not by itself. Cincinnati's normal first freeze is October 25, and days after it can still be warm enough to paint. What matters is the night after you paint, the dew at dusk, and whether the wall stays above the can's minimum while the coat cures.
What happens if exterior paint gets cold or wet before it cures?
Sherwin-Williams lists surfactant leaching, mildew growth, frosting and adhesion problems. Dew can seep into uncured paint and stain the surface.
