Fix using stainless steel or A4-grade screws to avoid corrosion staining, pre-drilling close to ends to prevent splitting. Left uncoated, the timber will weather to a silver-grey patina; apply a suitable exterior oil or microporous coating if you want to retain the warm brown tone and extend surface life.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDoes ThermoWood D corner trim need treating before installation?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt does not require preservative treatment as the heat treatment process permanently improves decay and moisture resistance.
