Marine Seal Wood Dock Stain

Product Datasheets

Marine Seal Wood Dock Stain is a long-lasting, semi-transparent dock stain specially formulated for use in the harsh marine environment.

Marine Seal is suitable for use on all types of wooden docking materials and provides extreme durability against the harmful effects of exposure to both fresh and salt water. Marine Seal has been specially formulated using state-of-the-art nano-particle technology to provide superior resistance against ultraviolet color fade and mold and mildew growth.

New cedar docks should be cleaned as quickly as possible to avoid damage from the sun and rain. Let oil-rich woods, such as mahogany, weather for six months prior to application. New, pressure-treated lumber typically contains a high degree of moisture and should be allowed to weather for 6-12 months prior to staining.

To achieve optimum results, Marine Seal should not be applied over previously stained surfaces, painted surfaces, or varnished surfaces. When staining composite lumber and exotic hardwoods, allow materials to weather for no less than 12 months. Prior to staining, clean all surfaces with Marine Seal Wood Dock Cleaner per label instructions. For all composite wood and exotic hardwoods, apply only one coat of stain.

Note: The 'wet' color of Marine Seal has a cloudy/milky appearance, but it will dry to a beautiful, semi-transparent finish.
