Helmsman® Spar Urethane is a specially formulated protective clear finish for exterior or interior wood that is exposed to sunlight, water, or temperature changes. It contains UV blockers to reduce the sun's graying and fading effects. Helmsman® Spar Urethane forms a protective barrier against rain and moisture and its special oils allow the finish to expand and contract with the wood as seasons and temperatures change.

Helmsman® Spar Urethane is not recommended for use on floors.

Directions

1.Surface must be dry and free of paint, wax, grease, polish, old finishes in poor condition or any foreign matter.
2.Sand to obtain a smooth, uniform surface. Remove all dust with a damp cloth.
3.If desired, apply stain, such as Minwax® Wood Finish™, to unfinished interior wood surfaces. Follow directions for application instructions and dry times.
4.Stir well before and occasionally during use.
5.Apply a thin coat of Helmsman® Spar Urethane using a high quality natural bristle brush. On unfinished wood, apply sufficient material to seal open joints, edges and end-grain.
6.Let dry at least four hours, then sand entire surface lightly with very fine sandpaper (220 grit) to ensure an even finish and proper adhesion of additional coats.
7.Apply second coat. If a third coat is desired, repeat Step 6 before applying. Note: For exterior surfaces or for previously unfinished wood, three coats are recommended.
8.After final coat, allow 24 hours before normal use.

Clean Up: For easy clean-up use mineral spirits or paint thinner.

Coverage: Approximately 125 sq. ft. per quart

Note: Dry times are based on good ventilation, temperature of 77°F and 50% relative humidity. Lower temperature, higher humidity, lack of air movement or application of thick coats will extend drying times. Always test surface for tackiness between coats. When used for exterior applications, maintain by lightly sanding and adding an additional coat(s) as conditions require.

Helmsman® Spar Urethane is not recommended for large exterior surfaces where maintenance would be difficult, such as decks and siding. Slight ambering may be experienced when Helmsman® Spar Urethane is applied over light-colored stains or wood surfaces. Always spot test on an inconspicuous area to ensure satisfactory results.
