18mm Marine Plywood Board, 2440mm x 1220mm, WBP Glue

18mm Marine Plywood Board

The 18mm Marine Plywood Board provides high-performance structural support for environments where moisture and humidity are constant factors. This panel uses high-quality hardwood veneers bonded with Water Boil Proof (WBP) phenolic resin to prevent delamination under extreme conditions. It serves as a critical component for boat building, external signage, and high-end cabinetry in damp areas.

Built for the Job

This material withstands prolonged exposure to water without losing structural integrity. Unlike standard interior ply, the core gaps in this sheet are minimal to prevent water pockets from forming within the layers. Contractors select this thickness for load-bearing applications where rigidity is paramount. The cross-laminated hardwood construction ensures the panel remains flat and resists warping even when subjected to fluctuating temperatures on a job site.

• Fabricating marine-grade cabinetry and furniture for coastal residential projects.
• Constructing durable exterior signage and hoarding for long-term commercial use.
• Creating subflooring in bathrooms and laundry rooms to prevent moisture damage.

Technical Specifications

What’s Included

• 1 x 18mm Marine Grade Plywood Sheet (2440 x 1220mm)

On-Site & Workshop Notes

• Seal all cut edges with a marine-grade epoxy or water-resistant sealant to maintain the integrity of the internal veneers.
• Use carbide-tipped saw blades to achieve clean cuts through the dense hardwood layers and phenolic glue lines.
• Store sheets flat on a level surface in a dry area to prevent any physical bowing before installation.
• Pre-drilling is recommended when using large fasteners near the edge of the panel to avoid splitting the grain.
