Why does exterior natural wood often appear to darken over
"darkening" effect frequently seen on exterior wood is caused
by the use of vegetable based products. These products, which
are usually linseed or tung oil based, become a food source
for mold and mildew. As the mold and mildew grows, it darkens
the wood surface. Repeated applications of linseed or tung
oil based products only increases the growth of mold and mildew,
resulting in unattractive, darkened wood.
What should I do if my wood is new?
wood contains moisture and natural oils, even though it is
said to be "dried." We recommend allowing new wood to "weather"
for one to two seasons before product application. This allows
the wood to continue to dry and will result in better penetration
and longer protection. However, application of linseed or
tung oil based products will often lead to problems of the
darkening effect described by the previous question. The best
solution is to avoid using these products from the beginning.
What are the cost factors associated with maintaining exterior
is the single most expensive factor involved in maintaining
natural wood. The time required to complete a job is divided
between properly preparing the wood for treatment and the
application of the new treatment. Properly preparing the wood
typically requires the removal of previous treatment(s). The
more difficult it is to remove previous treatments, the higher
the cost of labor involved to complete the job. One way to
lower labor costs is to reduce the time required to prepare
your wood for repeated applications. The time involved in
the application of a product will generally be the same.
Why should wood be cleaned or stripped before applying most
wood preparation is equally as important as proper application
of any product. This usually involves the removal of the previous
application, even if it is being re-coated with the same product.
The removal process can be very difficult, labor intensive,
and sometimes requires the aid of stripping agents. The result
of re-coating over most products will lead to an unattractive
surface build up, uneven weathering and the darkening effect.
Most products will adhere better and last longer if applied
to bare wood instead of a previous layer of stain.
What product does Mountain Woodcare recommend for exterior
work methods and procedures are important factors in achieving
good results in the restoration and preservation of natural
wood. Having used several different products and having
stripped off many others, we have found one product to be
superior to the competition. Woodcare Professional Series
Exterior Natural Wood Stains by The Boodge Company eliminate
the problems commonly associated with vegetable based (linseed
or tung oil) products. The Woodcare Series is petroleum
based, thus eliminating the darkening effect caused by
mold and mildew growth associated with vegetable based
products. The Woodcare Series also has deep penetrating
properties that replace the moisture and naturl oils lost
from wood due to weathering. As the oil migrates into the
wood, the resins create a surface barrier protecting it
from outside moisture and sun, while holding the moisture
replenishing oil in. What makes this product further superior
is that it requires minimal preparation for reapplication.
Light power-washing is all the preparation required for
repeat applications. This can reduce the preparation time
by 30-70%, significantly reducing maintenance costs. In
addition, Woodcare Oil protects evenly, has no surface
buildup, and gives wood a deep, rich and natural look.
An important thing to consider is what is your home going
to look like in five to twenty years after several applications
of any product. This product will not only maintain a "like
new" appearance after multiple applications, but will
also protect the wood better and longer after each application.
