Owatrol white decking paint should be applied at temperatures between 10°C and 35°C. Do not apply the paint in direct sunlight, on hot surfaces, or if cold or wet weather is expected within 48 hours of application. Applying paint in unsuitable conditions can significantly affect adhesion, drying time, and the long-term durability of the finish. In the UK, spring and early autumn — when temperatures are mild and rainfall is more predictable — are typically the most favourable seasons for painting exterior decking.
