Specification
- Marine, film-faced or commercial?
- Three different boards sold under one word, and the adhesive is what really separates them. MARINE — this page — is bonded with WBP phenolic right through and laid up without voids, for anything that gets wet or stays humid. FILM-FACED (shuttering) is a WBP-bonded board with a phenolic film on both faces, bought to strike concrete and be used again. COMMERCIAL is an MR-bonded interior board for carpentry and fit-out, and will delaminate if it gets wet. If the work is concrete, film-faced; if it gets wet, marine; if it is dry interior work, commercial.
- What makes it marine
- Two things together, and it needs both. A fully waterproof (WBP) phenolic adhesive in every glue line, and a core laid up from dense hardwood plies without gaps or voids. The adhesive is what survives the water; the void-free core is what stops the sheet delaminating from the inside once water finds a cut edge.
- The standards buyers ask for
- BS 1088 is the marine plywood specification, and EN 314-2 Class 3 is the bond class for exterior and wet service. If your specification calls for either, say so with the enquiry and we will confirm what the shipment actually carries before you commit.
- Standard size
- 1220 × 2440 mm (4 × 8 ft) sheets · 2.98 m² each · 336 sheets to 1,000 m².
- Thicknesses
- 4, 6, 9, 12, 15, 18 and 25 mm. 12 and 18 mm are the usual ones; 18 mm is the structural thickness.
- Surface and finishing
- Sanded raw hardwood veneer both faces, with no coating, so it takes paint, varnish, preservative or a bonded laminate directly. Seal the cut edges — that is where water gets into any plywood, marine included.
- Where it is worth the money, and where it is not
- Worth it for boat and dock work, wet-area joinery, and bathroom or kitchen carcasses near plumbing. Not worth it for dry interior framing, partitions or ceilings — that is what commercial plywood is for, at a fraction of the cost.
- Telling it apart on site
- A hardwood face with no knots showing, and an edge that reads as fine even plies with a continuous glue line and no voids. A commercial sheet cut alongside it shows a coarser core and visible gaps.
