Fix with hot-dip galvanised or stainless steel nails or screws to prevent corrosive reaction with the treatment salts. Cut ends should be treated with an end-grain preservative before fitting, as factory treatment does not fully penetrate exposed cuts.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat is a gravel board used for in fencing?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA gravel board sits horizontally between fence posts at the base of a fence run, creating a buffer between the soil and the fence panels or feather edge boards above.
