Can You Paint in Cold Weather? (Seattle Guide)

Short answer: yes—with low-temp products, moisture checks, and smart timing. Here’s how Seattle pros schedule, spec, and execute exterior work when temps dip.

Quick Answer (What Has to Be True)

Low-temp paint (rated 35–40°F) Surface & air within spec Dew-point margin ≥ 5°F No rain during cure Extra dry/recoat time

Rule of thumb: If the substrate is dry, temps stay above minimums, and dew won’t form before the film sets—you can paint.

Seattle’s Winter Variables (What Makes It Tricky)

Our marine climate brings wet substrates, cool nights, and short daylight windows. North/east elevations stay damp; south/west can still flash hot in rare sun. Pros plan by elevation, follow the shade, and watch hourly forecasts (temp, humidity, wind, dew point)—not just the day’s high/low.

Cold-Weather Product & Conditions Matrix

FactorTarget / GuidanceWhy It Matters
Paint type100% acrylic, low-temp rated (35–40°F)Coalesces at lower temps; better flexibility/adhesion.
Air & surface temps≥ product minimum (often 35–50°F)Below spec risks poor film formation and adhesion.
Dew-point margin≥ 5°F (10°F safer) through eveningAvoids condensation and surfactant leaching.
Humidity40–75% preferredVery high RH slows dry; very low can flash-dry.
Rain windowDry through cure time (check TDS)Prevents wash-off and gloss/sheen issues.

Scheduling Tactics That Work in Seattle

  • Start late morning: Let siding dry after fog and overnight dew.
  • Paint the shade band smartly: Work elevations as they warm, not as they cool.
  • First coat early, second coat earlier: Leave enough runway before evening temp drops.
  • Prioritize substrates: Sun-exposed fiber-cement first, deep-shade wood later once dry.
  • Use meters: Moisture and IR thermometers beat guesswork.

Prep & Application Adjustments (Cold-Season)

  1. Thorough wash & dry-out: Kill/clear mildew; allow 24–48h+ as needed.
  2. Selective priming: Spot prime bare wood; stain-block cedar; masonry primer for stucco.
  3. Film build: Two finish coats at labeled spread rate—not one heavy pass.
  4. Longer recoats: Follow cold-weather recoat windows; don’t rush.
  5. Vent & protect: Mask carefully; protect from overnight dew and wind-driven mist.

“Why Us” vs. Typical Painters (Cold-Weather Projects)

Refined Painting

  • Low-temp-rated systems + substrate-specific primers
  • Hourly forecast planning (temp/RH/dew point/wind)
  • Moisture & IR temp meters on every elevation
  • Process built for PNW (shade sequencing, early finishes)
  • 5-year workmanship warranty

Others

  • “One-size” paint choice regardless of temps
  • Plans by daily high/low only
  • Guessing on substrate temp & moisture
  • Late-day coats that run into dew
  • Limited or no warranty clarity

Common Cold-Weather Mistakes

  • Painting late: Film hasn’t set before dew → streaks/blush.
  • Ignoring surface temp: Siding can be 5–10°F cooler than air.
  • Coating damp wood: Traps moisture → early failure.
  • Rushing recoats: Extinguishes intercoat adhesion in the cold.

Frequently Asked Questions

What’s the absolute lowest temp you’ll paint at?

We follow the product’s TDS. With low-temp acrylics, that can be 35–40°F—if the surface is dry and dew won’t form before cure.

How do you know the surface isn’t too cold?

We use IR thermometers; surface temps can trail air temps by 5–10°F in shade.

Will cold weather change the sheen?

It can. Poor conditions can cause surfactant leaching or uneven sheen. We schedule to avoid that.

Can interiors be painted in winter?

Absolutely. Interiors aren’t weather-dependent—ventilation and temps are controlled.
