Description
Deck & Shake Specialty Sealer can be used to effectively protect from Chromated Copper Arsenate as well as other potentially hazardous chemicals.
There has been much concern about Chromated Copper Arsenate treated lumber by the public as well as the lumber industry. The public is worried that the levels of carcinogens that can be leaked from the treated lumber may pose a health risk to those who come in contact. Most studies suggest that risk is minimal, however given the status of "minimal risk" hasn't quelled the publics concern. Some have suggestes to abstain from using treated lumber, however the lifespan of untreaded lumber is significantly limited to that of its treated counterpart. With the expense of replacing damaged wood or risking structural failure, treated wood wins favor. Other synthetic materials can be used but they can be more expensive and tend to not have the "feel" of a structure that was intended to be wooden. The alternative that keeps structures standing and the public safe is to seal the treated wood.
Several researchers have reported that stains/sealants/coatings can reduce the rate of leaching CCA compounds from treated wood and that the effectiveness of these coating materials over time varies greatly, depending on the type of surface coating used and environmental conditions effecting the wood. Stilwell (1998) reported over 90% reduction in dislodgeable arsenic residues from CCA-treated wood surfaces coated with a oil-based alkyl resins for samples tested one year after a sealant was applied. CDHS (1987) reported 96%, and 82% reductions in dislodgeable arsenic from stained CCA-treated wood surfaces after one month and 2 years, respectively.
