If moving panels from cold or damp storage into a warm interior, allow 24 to 48 hours for acclimatisation before cutting or fixing to reduce the risk of movement once installed. Fix using stainless steel or galvanised fasteners in external or wet applications, and always seal all cut edges with a suitable primer or end-grain sealer before finishing to maintain moisture resistance.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between BS1088 marine plywood and standard exterior plywood?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eBS 1088 marine plywood is manufactured to a stricter standard than general exterior or WBP plywood.
