Understanding the UK Climate and Its Impact on Painting

The UK’s unique weather patterns significantly influence exterior painting projects. Our climate is characterized by:

• Spring: Mild temperatures (10–20°C), reduced rainfall, increasing daylight
• Summer: Warmer temperatures, longer dry spells, occasional heatwaves
• Autumn: Cooling temperatures, increasing rainfall, shorter days
• Winter: Cold temperatures, high humidity, frequent rain, minimal daylight

Temperature and humidity levels play crucial roles in paint application and drying:

Temperature Effects

• Low temperatures prevent proper paint drying and adhesion
• High temperatures cause too-rapid drying, leading to brush marks
• Ideal temperature range: 10–21°C for optimal results

Humidity Impact

• High humidity slows drying times and may cause blistering
• Low humidity allows proper paint curing
• Avoid painting in very damp conditions
