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.
