Q: What is UV PLUS?
A: UV Plus is a
penetrating wood stain and oil finish that beautifies and protects
exterior wood,
providing a natural appearance. It is ideal for use on cedar, pine and
redwood and comes in a variety of tones and semi-transparent colors. UV Plus
contains fungicides and UV absorbers of the highest quality. It
does not form a surface film when properly applied and is not subject
to peeling and flaking. To recoat, just clean and/or brighten the wood
surface and reapply UV Plus. No stripping or sanding is necessary.

Q: How long will it last?
A: On vertical,
smooth surfaces, UV Plus can be expected to last for 2-3 years, on
rough surfaces, 3-4 years and on decks 1-2 years. The time element will
vary depending on conditions such as sunlight, weather and direction of
exposure.

Q: I want to keep my wood looking natural? Should I
use a clear finish?
A: Clears with
no pigmentation do not
offer UV protection or color retention. Our products contain
Transparent Iron Oxide pigments which absorb UV radiation while
allowing visible light to pass through. This results in a finish that
highlights the natural beauty of the wood while still protecting it. We
suggest using our transparent finish that
is designed for the type of wood, such as Natural Redwood for redwood,
Natural Cedar for cedar, and Pine/Fir for pine or douglas fir. This
allows you to maintain a natural look and provide extended color
retention and protection to the wood.

Q: After I applied UV Plus, there are areas that are
shiny and tacky. What happened? How do I fix it?
A: This is
usually
caused by oversaturation of UV Plus on the wood. Remember, UV Plus must
be able to penetrate completely to work properly. Remove any excess
material promptly. Within 48 hours of application, scrub affected areas
with lacquer thinner or MEK solvent to soften excess material. Wipe
dry. If product has cured to the point that this does not correct the
problem, excess material must be removed by chemical stripping or
sanding. Dispose of clean up materials according to local, state and
federal regulations.
Another cause of
shiny tacky areas is applying the product to wood that is too damp. An
oil based product applied to a wet deck will not penetrate very well,
as the oil and water don't mix. Make sure that the deck is thoroughly
dry before applying any oil based product. Lumber that may appear to be
dry or dry at the surface can still have a high moisture content that
may "push" the oil back out if the boards are
heated up by the sun later in the day.

Q: Can UV Plus be applied over another stain?
A: Yes, provided
the previous finish has sufficiently weathered to allow penetration of
UV Plus. For best results, clean the surface with WD Wood & Deck
Renewer, Wood & Deck Cleaner and Brightener, or sand to a new
surface.

Q: What is the proper temperature to apply UV Plus?
A: We recommend
surface and air temperatures between 45F and 90F. Avoid application in
direct
sunlight on hot days. If the wood is hot to the touch, it is too hot to
apply UV Plus.

Q: How long should I let my deck weather before
applying UV Plus?
A: Redwood decks
should weather six to eight weeks minimum before applying UV Plus. The
wood needs to weather sufficiently to allow the pores to open up to
accept the stain. Failure to do so will cause premature failure and
possible surface sheen problems.

Q: Why doesn't UV Plus bead water?
A: Water beading
is accomplished by adding waxes or paraffin to the stain. These
additives do not
last very long and are not good permanent water repellents, in addition
to this they interfere with adhesion should you decide to paint over
the stain. That's why we don't use them in our products. The high
solids content of UV Plus fills the pores of the wood, providing
excellent water repellency that will last.

Q: The weather report predicts rain tomorrow. Can I
finish my deck today?
A: We wouldn't
recommend it. UV Plus needs at least 24-48 hours to dry in good
conditions. If a newly stained deck is rained on, the rain can force
the stain up out of the pores of the wood, leaving a blotchy
appearance. It's best to wait until there is no precipitation expected
for 48 hours. In some regions, this may mean waiting for a different
time of year to finish the deck.

Q: Is UV Plus suitable for vertical surfaces? Can it
be used on log homes?
A: Absolutely!
UV Plus
is an excellent choice for almost any exterior wood surface, including
vertical surfaces.
It can be used on siding, log homes, and wooden shakes. Make sure the
surface is clean, dry, and any previous coatings have either weathered
away or been removed. Do not use UV Plus over paints or other film
forming coatings, it's designed to penetrate into bare or weathered
wood surfaces.

Q: I want a shiny finish. Can I put multiple coats
of UV Plus on the wood?
A: No. The only
way to get a shiny surface on the wood is by using a multiple coat,
film forming finish. We don't
recommend clear film forming finishes on decks because they are
slippery when wet, they will eventually peel, and they are difficult to
maintain and recoat. When properly applied, a penetrating finish like
UV Plus will not be shiny, it will have a natural, matte look. For a
glossy or satin appearance on vertical surfaces, we recommend our Timberflex
products.

Q: Can I use UV Plus on pressure treated wood?
A: Yes, UV Plus
works great on pressure treated lumber. If you're working with new
wood, it's best to let it season
for several weeks to allow it to dry out and stabilize.
EPA studies show that applying an oil based,
penetrating sealer to CCA treated wood will reduce leaching of harmful
chemicals in the wood. CCA lumber for residential use was phased out in
2004 due to health concerns, but UV Plus is suitable for all other
commonly used types of pressure treated wood, including ACQ and copper
azole.
