Treatment starts with identifying what the timber received at the factory. Dip-treated and pressure-treated buildings can have different maintenance instructions, and decorative colour is not automatically the complete weather-protection system.
Follow the maker's timing
Read the warranty and coating instructions before assembly. Check compatible products, preparation, drying conditions and whether cut ends need immediate attention.
Work around the whole building
The least visible wall often gets the hardest weather and the poorest access. Keep vegetation clear, inspect joints and edges, and deal with leaks or trapped water before applying another coat.
A detailed seasonal maintenance schedule will be added after product instructions and coating sources have been verified.
