Wood Facts
By Joseph Flores, Renew Wood Restoration Co.
All unprotected wood exposed to exterior weathering is susceptible to erosion and biological attack. This natural weathering process results in wood changing its appearance from the beauty of new wood to various shades of gray and eventually to black. Left unprotected, new wood's durability, beauty and natural coloration is under constant attack. The enemies of your exterior wood surfaces are:
Sunlight. Solar radiation is the most damaging component of the outdoor environment affecting every exposed surface. The first change you will notice in your exterior wood will be the damage inflicted by sunlight. This will be seen by an initial color change from its beautiful golden, orange-brown color to gray.
Water Absorption by the Wood. Sun and rain cycles cause moisture fluctuations in the wood. The shrinking and swelling stresses the wood causing checks and splits to develop. Hydrolysis (as in acid rain attack) is also a contributor to this degradation of your wood.
Fungi, Mold and Mildew. Wood's natural protectants leach out in a relatively short time and allow colonization by wood-inhabiting fungi. Once established, and aided by favorable climatic conditions, these microorganisms can have a rapid, devastating effect causing your wood to become soft, stringy, pitted, cracked or even to crumble.
Depletion of Old Growth Timber. Another important consideration is that the majority of today's cedar and redwood lumber is being processed from younger, less decay resistant trees. These young redwood and cedars harvested today may need protection earlier than the premium hard woods that were once widely available. These factors, coupled with an increased awareness of various environmental issues in recent years to protect what remains of our old growth timber, are further reducing the supply of high quality wood.
HOW FAST WOOD WEATHERS IS DEPENDENT ON SEVERAL FACTORS:
Slope - Verticals and horizontals will reach different shades as they are exposed to different levels of sun, dirt and moisture. The more horizontal wood is, the more likely it is to suffer decay from fungi.
Direction - South-facing wood suffers because it experiences the greatest swings in temperature and humidity, leading to more splits and other degradation.
Shading - Wood shaded by trees is more likely to develop mold, mildew, and decay than unshaded wood.
DON'T GIVE UP!
In spite of the relentless enemies our exterior wood surfaces face, not only can they be restored, in most cases, to look like new, but they can also be easily maintained! The transformation process involves repair, mold and mildew removal, wood surface preparation; and application of a protective coating.
