Marine plywood is famous for being durable and water resistant, which is why it is an ideal material for use in applications such as boats, outdoor furniture, kitchen cabinets, and many more projects that may accidentally come into contact with water. However, like all other wood products, marine plywood may be compromised by fungus if not properly maintained over time. Fungi love damp, wet environments, and if a piece of marine plywood is not maintained properly, it can eventually lose all of its structural integrity and visual appearance. The following basic maintenance concepts will help to ensure that your marine plywood remains looking great and is also protected from fungal growth and damage.
Keep it Clean and Dry
The most simple, and maybe even the most effective way, to prevent fungal damage is to keep the surface clean and dry. Take the necessary time to wipe the surface down regularly to remove any dirt, dust, or organic material that will attract moisture. If the marine plywood is used externally, or in any other humid environment, ensure that it has enough ventilation to allow air movement so that moisture can evaporate. Royale Touche marine plywood is designed for maximum resistance, but cleaning the surface only helps its natural durability!
Use a Waterproof Coating
While marine plywood is made to withstand water, applying a separate layer of protection further enhances its performance. Use varnish, sealant, or epoxy to coat all surfaces, including cut edges. This second coating adds yet another level of protection against water penetration and reduces the likelihood of fungal growth. Reapply when warranted or after an unusually heavy rain or moisture exposure. Using plywood of good quality, such as Royale Touche, will also assist in the application of the coating and enhance the longevity of performance of the surface coatings over the marine plywood’s lifespan.
Seal as Recommended
Edges are the most likely point of entry for fungal invaders because they can absorb moisture much quicker than other areas of the marine-grade plywood. Always seal the edge before installation with a quality wood sealer or clear epoxy resin. If items will be going outdoors, be sure to seal all joints and corners where moisture may be trapped and held longer than listed on the abrasion itself. A quality edge seal will help extend the overall lifespan of marine plywood without structurally compromising the performance of the product.
Inspect and Treat Early
Be sure to routinely inspect any marine plywood for damage from fungal growth. During your routine inspection, look for brown stains or discoloration, musty smells, and/or soft spots of wood in one area. Treating one small area for fungal growth is much easier than trying to treat a large area for recovery if left untreated. Cleaning the plywood with a mild disinfectant bleach solution or antifungal wood cleaner will clean the plywood of spores to limit continued growth of fungi.
Conclusion
Marine plywood is durable and reliable for its intended use, but a large part of the performance and reliability relies on proper maintenance. Routine cleaning, sealing, coating, and inspecting will add protection from fungus growth and environmental damage. A little time spent on simple maintenance will lead to more years of marine plywood beauty and a fungi-free experience.
