1. Why does
exterior natural wood often appear to darken over time?
The "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.
2. 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.
3. What are
the cost factors associated with maintaining exterior natural wood?
Labor 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
Why should wood be cleaned or stripped before applying most products?
Proper 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 eventually 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.
5. What product
does Woodcare of Evergreen recommend for exterior natural wood?
Proper 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 of Exterior Natural Wood Products from Boodge Company eliminate the problems
commonly associated with vegetable based (linseed or tung oil) products.
The WoodCare Professional Series is petroleum based, thus eliminating the
darkening effect caused by mold and mildew growth associated with vegetable
based products. The WoodCare Professional 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 future 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.
