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 6 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 will dry to a beautiful, semi-transparent finish.
