CWF-UV is a clear wood finish that’s designed
to restore the rich, warm appearance of natural wood. CWF-UV protects
against damage caused by moisture and ultraviolet rays, and provides
a mildew-resistant finish that won’t crack, peel or flake.
• For exterior use only
• Weathered exterior woods including Cedar, Redwood and Pressure-Treated
• Horizontal and vertical surfaces such as decks, siding, fences
1. Surfaces must be thoroughly clean, dry and free of dirt, grease,
grime, mildew and previous coatings.
2. Remove mildew with a solution of 4 ounces of non-ammoniated detergent
(TSP), 1 quart of outdoor bleach and 3 quarts of fresh water. Allow
this solution to remain on the surface for 10-15 minutes, then rinse
3. Clean weathered wood with Flood Wood or Cleaner Flood Dekswood®.
4. Remove old finishes with Flood Wood Stripper or FloodPro® Stripper/Cleaner.
5. After cleaning, allow wood to dry 48 hours or until it has reached
a moisture content of 15% or less before finishing.
New wood surfaces have a hard shiny surface called mill glaze that prevents
maximum penetration and bonding of a finish. To properly prepare the
surface for application, treat with a solution of Flood Wood Stripper,
diluted one quart per gallon of water. Test wood for absorbency by sprinkling
water on the surface. If water is absorbed rapidly, the surface is ready
Uncoated wood surfaces that have weathered longer than six months require
thorough cleaning before applying a finish. Use Flood Wood Cleaner®
or Flood Dekswood® (according to label instructions), along with
a pressure washer or stiff bristle brush to remove the loose fiber,
dirt and other surface contaminants.
Apply to bare wood surface or a weathered wood surface that was previously
finished with CWF-UV. Other previous stain, varnish or sealers must
be completely and thoroughly removed with Flood Wood Stripper or FloodPro®
Stripper/Cleaner per label directions, before proceeding.
NOTE: Cedar and Redwood may darken with Flood Wood Stripper or FloodPro
Stripper/Cleaner. If this occurs brighten with Flood Wood Cleaner or
Flood Dekswood before proceeding.
• Brush: High quality, synthetic stain brush
• Roller: Synthetic, woven cover 3/8”-3/4 “ inch
• Spray: Air-Less sprayer .017 - .021 fluid tip/ 1800-2100 psi
CAUTION: Surfaces are slippery when wet. Use caution when walking on
wet surfaces during application.
1. Stir. Use as is, do not thin.
2. Mix thoroughly before and periodically during application.
3. For color uniformity, intermix in one container, all finish to be
an entire section.
4. Cover everything you do not wish to coat, including plants and shrubs.
5. Apply between 50°F and 80°F.
6. Do not apply if cold and/or wet weather is expected within 48 hours.
7. Always work the entire length of a deck board or horizontal siding
a logical break, such as a window or door frame.
8. Vertical siding should be coated from top to bottom.
9. Never stop application in the middle of the board or wall.
10.Never apply in direct sunlight or to hot surfaces.
11.For external use only, do not use indoors.
12.In most cases a single coat of CWF-UV is sufficient.
13.For porous or older wood, apply a second coat before the first coat
dries (usually within 20 minutes). Do not apply a second coat if the
first coat has dried.
14.After spray application, back brush or backroll to improve penetration
and uniformity of coverage.
15. Wipe up any puddles to avoid shiny areas, (within 20 minutes).
NOTE: CWF-UV is not a surface coating. It protects by penetrating the
• 150-250 sq. ft/gal (13.9-23.3 sq. m/gal)
• Coverage varies based on age and density of wood
• Most decks do not have to be coated every year
• A single coat of CWF-UV® every second year will be sufficient
to refresh the natural beauty of your deck and to maintain protection
• Between recoats, a periodic cleaning with Flood Wood Cleaner
or Flood Dekswood Cleaner to remove dirt and contamination will renew
the appearance of the wood
• On siding and other vertical wood including fences, exterior
furniture, use as directed in steps 1 through 3 under “Application”
• Surfaces with harsh exposures to the sun, weather or foot traffic
will show wear more quickly than other areas – If this happens,
clean effected areas with Flood Wood Cleaner and recoat as necessary,
blending into areas which still have good color
• For general recoating follow directions in “General Surface
Preparation” and “Application”
• Vertical surfaces do not require annual maintenance
• Surfaces with harsh exposures to the sun and weather will show
wear more quickly than other areas – If this happens, clean effected
areas with Flood Wood Cleaner and recoat as necessary, blending into
areas which still have good color
• Areas retaining good color do not need recoating
• Badly weathered areas may require 2 coats (apply the second
coat before the first coat dries). Do not apply a second coat if the
first coat has dried.
• Backbrush or backroll to improve penetration and uniformity
• Cleanup with soap and water
• Store unused portion in tightly closed container
• KEEP FROM FREEZING
