DEFY Marine Seal Wood Dock Stain is a long-lasting, semi-transparent dock stain specially formulated for the use in the harsh marine environment. Marine Seal Wood Dock Stain is suitable for use on all types of wooden docking materials, providing extreme durability against the harmful damaging effects of exposure to both fresh and salt water. Marine Seal Wood Dock Stain has been specially formulated, using state-of-the-art nano particle technology, to provide superior resistance against ultraviolet color fade, graying & peeling.


Allow new wood to weather for 3 to 6 months to adequately dry out prior to application. If sanding is necessary to remove older finishes, use a coarse grit sandpaper. Avoid using fine grit sandpapers as they can adversely affect the penetration of the stain.

CLEAN: Dock surfaces must be clean, porous, and dry before applying DEFY Marine Seal Wood Dock Stain. Use DEFY Marine Seal Wood Dock Cleaner to remove mill glaze, mildew, graying and other foreign matter that might block surface pores and interfere with product penetration. Rinse thoroughly with garden hose or pressure washer (maximum 1200 p.s.i.). DEFY Marine Seal Wood Dock Cleaner will darken redwood and some types of cedar; apply cleaner in a test area to insure proper results prior to proceeding on the entire project.

Note: Be sure to rinse completely as any cleaning products left on the surface could cause premature stain failure.


Weather Conditions: Surface and air temperatures should be between 45°F and 95°F. Avoid application in direct sunlight. Do not apply to wet or water saturated surfaces, or when rain is expected within 12 hours. Stain may be applied to wood surfaces the same day as cleaning and brightening as long as surface is visibly dry before staining.

MIX WELL: Shake or stir contents before and periodically during use. To ensure absolute color uniformity from container to container, mix at least one third of the product from a used container with the contents of a new one. Do not thin product.

PROTECT ADJACENT AREAS: Use plastic, cardboard, and/or drop cloths to protect all adjacent non-targeted surfaces such as siding, windows, masonry, plant life, etc. from overspray and runoff. Immediately remove overspray from non-targeted areas with soap and water. Overspray that is allowed to dry will be difficult to remove; dried product cannot be removed from concrete and masonry.

USE THE RIGHT EQUIPMENT Hand brushes should be high quality nylon or polyester. A paint roller may also be used. If using an airless sprayer, use tips between .013 and .015, and use the lowest pressure that achieves a uniform spray pattern to minimize fogging and overspray when spraying. To insure a uniform finish, it is always best to back brush when spraying.

HORIZONTAL SURFACES: On horizontal cedar, mahogany, and other dense woods, apply only one coat of finish. For pressure treated lumber and other porous woods apply two wet-on-damp coats, waiting 10-20 minutes between coats. It is very important to not let the first coat dry completely before applying the second coat. Brush product into surface working out all drips, puddles, or areas of overspray before product dries. Do not over-apply finish. To avoid the possibility of peeling, apply only as much finish as the wood can easily absorb. A sure indication of over application is a shiny appearance. Two coats are usually adequate, but depending on the porosity of the wood, more or less stain may be needed. Complete entire sections or to a natural break before allowing to dry. Never break in the middle of a board. Thoroughly coat the ends of boards or logs to prevent water penetration. Horizontal surfaces may require maintenance coats more frequently than vertical surfaces as they typically receive more direct sunlight as well as more wear and tear.

VERTICAL SURFACES: Start from the bottom and work up. Treat the entire length of a board before moving up. If necessary, brush or feather in to avoid lap marks. Brush in product before it dries and work out drips, runs, or overspray.

COMPOSITE WOODS: When staining composite lumber and exotic hardwoods, allow materials to weather for no less than 12 months. Prior to staining, clean all surfaces using DEFY Marine Seal Wood Dock Cleaner per label directions. For all composite wood and exotic hardwoods apply one coat of stain.

DRY TIME: To touch, 2 - 6 hours depending on temperature and humidity. To avoid any stain being tracked onto boats, check surface for "tracking" prior to re-opening the dock to foot traffic.

CLEANUP: Clean tools and equipment immediately after each use with soap and water.

COVERAGE: With two coats, Marine Seal Wood Dock Stain will cover approximately 100 - 150 sq. ft. per gallon, depending on wood texture and porosity.

Note: The “wet” color of DEFY Marine Seal Wood Dock Stain has a cloudy/milky appearance but will dry to a beautiful, semi-transparent finish.

IF INHALED: Move the affected person away from the contaminated area and into the fresh air. If symptoms persist, seek medical advice. SKIN CONTACT: Wash off immediately with soap and plenty of water. Obtain medical attention if irritation persists. EYE CONTACT: Immediately flush eyes thoroughly with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Seek medical attention if irritation persists. INGESTION: If swallowed, rinse mouth with water (only if the person is conscious). Do NOT induce vomiting unless directed to do so by a physician. If the person is fully conscious, make him/her drink water. Never give an unconscious person anything to drink. Immediately call a POISON CENTER or doctor/physician. For additional information for this product, consult the Product Data Sheet or Safety Data Sheet available at


When wood begins to fade a light maintenance coat is recommended. Simply sprinkle water on the surface of the wood. If the water is easily absorbed within 1 - 2 seconds, the stain has weathered sufficiently to be recoated.
