It may be difficult to understand why a deck seems to weather so
quickly. It turns gray from the weather and fades quickly. Unlike your
siding or roof, there is no place for snow, ice, and rain to trickle
down. Your deck is horizontally exposed to the elements, meaning that
any snow or rain buildup on the deck will not slide off. Decks can have
very large surface areas, allowing them to potentially catch very heavy
loads of snow on top of the grills, chairs, and tables already on them.
Water and snow has to evaporate or melt all by itself on these decks
since there is the tendency for precipitation to pool and accumulate on
decks, causing the gradual wearing away of the beautiful wood that the
deck was built with.
Due to this fact, it is extremely important to to apply a wood stain
that will not only protect your deck from rain and snow, but the
damaging UV rays from the sun. The sun is a real culprit when it comes
to decks. Because they have such a large surface area, it has the
tendency to catch incredible amounts of UV rays, promoting the graying
and general deterioration of the wood over time.
A clear or transparent wood stain gives you much less protection than a
semi-transparent or opaque wood stain because there is less pigment
between the wood and the sun. You can absolutely prevent ugly graying
and stain fading over time by applying a semi-transparent or opaque wood
stain to block UV radiation from penetrating the wood. An opaque wood
stain is just that, opaque, and does not allow the grain of the wood to
be visible. It does however accentuate the wood's texture. If you are
looking for a stain that allows most of the grain of the wood and all of
the texture of the wood to show through, then a semi-transparent stain
will fit your bill. This type of stain provides for more protection than
a clear stain but less protection than an opaque stain due to the
amount of pigment it has. Even clear stains will alter the look or color
of the wood, so find a stain that will accentuate the color of the wood
and provide the most protection.
It is prudent to look for a deck stain that provides some type of UV
protection, or else the sun will start fading away your expensive deck
staining project the moment you apply it. Just as the sun fades the look
of outdoor rugs, it fades the pigment in your deck stain. The high
level of maintenance decks require can be a pain for homeowners, but
careful routine maintenance can prevent major deck overhauls in the
future.
