Weather conditions affect paint application and can impact adhesion and finish. The ideal air temperature is between 10°C and 25°C. It needs to be dry, not damp, with a maximum of 80% humidity and no risk of rain during the application or drying period.
Painting in extreme temperatures (either too cold or too hot) can cause paint to dry too quickly or too slowly, affecting the adhesion and finish.
Windy conditions will also adversely affect drying times and can lead to paint contamination.
The temperature of the substrate / material you are painting also needs to be considered - it must be a minimum of 5°C but not too hot.
If the exterior material (e.g. doors / window frame) feel hot to touch this could affect application, adhesion and finish.
It is advisable to apply paint out of direct sunlight - for example painting in mornings is advisable in summer rather than midday heat.
