Marine plywood is commonly used to replace a rotting boat floor. This type of plywood is specially treated to resist rotting in high moisture environments. Marine plywood is premium quality plywood selected based on density and bending strength. It is available in different appearances, grades, thicknesses, lengths and widths.
Pressure Treated Plywood
Pressure treated plywood is also used to replace boat flooring. This type of plywood is treated to be more resistant to weather damage. It typically has a greenish color due to the chemicals used in the treating processes. Pressure treated plywood is treated with mold growth retardant and the treating process is not water soluble, which reduces water adsorption in the wood.
Marine Vinyl Flooring
Marine vinyl is another option for replacing a boat's floor. Marine vinyl flooring protects against sunlight, water, mildew and oil. Marine vinyl is also commonly used on boat seats. It is durable and easy to install.
Fiberglass as a Preventative Measure
A variety of boat floors are constructed using wood plywood with carpet on top. After years of being exposed to moisture, the wood naturally begins to rot and will need replacing. One preventative measure boat owners can take is to fiberglass their boat floors. This strong durable material is waterproof and will not rot.
