Wet area applications – which plywood is best?
There is a common misconception that Marine Plywood is the only plywood able to withstand contact with moisture. Marine Plywood is the correct plywood choice if timber is directly immersed in water for lengthy periods ie: boat building.
Birch plywood provides functional alternatives. Although not suitable for total immersion in water, Birch plywood, when properly protected, may be used as a suitable alternative in areas with moisture.
Marine Plywood is specifically designed with structural impact-resistant strength to absorb the effects of water movement and pressure. Marine Plywood is designed and manufactured at the very highest standard – no core gaps – both ply faces are “A” grade veneer & totally defect free – as in Hoop Pine Plywood, Australian Standard AS/NZS 2272; or Pink Marine Ply British Standard BS 1088. B/BB grade northern European Birch timber is a cold climate timber with growth rings close together providing exceptional strength & durability for the core & veneer layers.
MAXI Plywood specialise in Birch plywood – MAXI Hex (phenolic hexagonal film coating); MAXI Film (choice of 10 coloured phenolic/melamine protective film coatings); MAXI Edge Fineline (designer birch sheets in veneer & solid panels); and MAXI Birch plywood sheets.
All plywood sheets, including Marine & Birch, are manufactured with the same Type A Phenolic Bond glue line – low formaldehyde rating. The moisture-preventative benefits of Marine Ply & Birch plywood are not only dependent on the quality of the glue line, unique veneer faces and timber core, but on how well the exposed plywood edges are sealed and protected. No exposed plywood face or edge is able to survive immersion or exposure to water unprotected – even Marine Ply. Both Marine Ply & MAXI Birch plywood exposed edges must be protected with layers of applicable water repellent products.
MAXI Plywood supplies high-quality plywoods including Russian birch, hoop pine, marine and other varieties of plywood, with cut-to-size and machining services.Learn more
