Key takeaways
- Aim for moderate temperatures, no rain and no heavy humidity.
- Read the temperature range on the paint can.
- Book early: the good season is short.
Temperature
Most latex paints need a temperature of around 10 °C or more during application and drying. Some formulas are designed for lower temperatures: always check the label.
Humidity and rain
- Avoid painting a wet surface or when rain is forecast.
- Morning and evening dew can hurt drying.
- High humidity slows drying and can affect the finish.
Sun and wind
Painting in full sun on a very hot surface can make paint dry too fast and leave marks. Following the shade through the day gives a better result. Strong wind blows dust and debris onto fresh paint.
Plan ahead
Because the good window is short, calendars fill quickly. Asking for a quote early in spring leaves more choice of dates.
