Frequently Asked Questions
What defines 15 mm marine plywood?
A plywood panel roughly 15 mm thick, made from multiple hardwood veneers bonded with WBP adhesive. Strong, dense and built to resist moisture.
Where is 15 mm marine ply best used?
Ideal for heavier-duty applications: boat decks, subflooring in wet outhouses, dock platform structures, or external facings where rigidity is needed.
Is this sheet fully waterproof?
It uses waterproof glue and durable veneers so it resists water exposure well. But the wood still absorbs moisture at edges or cuts unless sealed.
How does 15 mm compare to thinner marine plies in strength?
Thicker board gives better rigidity and load-bearing, less flex. Smaller chance of sagging or deflection under load compared to thinner sheets.
Can I cut, drill or shape this 15 mm marine plywood easily?
Yes — though the thickness requires good tools: sharp saws, pilot holes for screws, clean work to prevent tear-out. Seal exposed edges after cutting.
What are the sheet sizes & can I get custom cuts?
Standard full‑sheet sizes (e.g. 2440×1220mm or similar), plus smaller panels. Many suppliers offer cut‑to‑size services.
How should I store a heavy 15 mm marine ply sheet?
Flat, supported, dry, off the ground. Avoid moisture contact, as warping can start from wet storage.
Is marine plywood 15 mm suitable for furniture or cabinetry?
Yes — especially for outdoor or moisture‑exposed furniture. Its hardness supports hardware well; visible surfaces can be finished nicely.
What finish options work well?
Use varnish, epoxy, paint or teaks oils. Protective finishes plus sealing edges help in longevity.
Do you offer trade/bulk pricing and what about delivery constraints?
Yes — bulk orders or trade accounts usually get better rates. Delivery might need more care due to weight; check lift/handling access.
