Pressure Treated Deck Washing, Cleaning, Stripping & Sealing, Repairs in MD, VA
It’s a fact that all decks built with pressure treated lumber contain chemicals of some sort. Pressure treatment helps to prevent rot and decay, especially at ground contact. However, it doesn’t protect your deck from UV damage. As a result, deck washing services are important in maintaining your investment, but they must be done correctly. Properly cleaning and sealing decks, screened in porches, gazebos, fences, playsets, sheds, and other wooden structures helps to protect your investment for many years to come.
Pressure Treated Wood Facts
The EPA’s December 12, 2001 report on this subject reads in part: “… Results of these studies as a whole support that surface coatings (applied after CCA treatment) are effective at reducing the quantities of dislogeable and leachable arsenic. Reductions of 70% to 90% in dislogeable arsenic were observed across the studies as CCA treated wood was subjected to natural weathering.”
Today two of the most popular pressure treatments are ACQ-Alkaline Copper Quat, and CA-B copper azole, which contain fungicides and insecticides. Both ACQ and CA-B meet the requirements for wood that comes into ground contact, and provides protection from insects, rot and decay.
Washing & Sealing PT Pine Decks
Maintenance washing is important for all types of decks. In particular, removing mildew and algae growth is extremely important to the health of the wood. Above all, the deck must be cleaned prior to applying any coating. With this in mind, some studies suggest that applying an oil based semi-transparent sealer or stain on a regular basis may reduce the aging of the wood. Hybrid products are also an option, but do not moisturize the wood as well. Notably, service should be performed annually or every other year depending upon wear and weathering of the coating. Having your deck properly cared for using low pressure washing and sealing on a regular maintenance schedule is the best way to protect your investment.
In selecting a finish, consumers should be aware that, in some cases, “film-forming” or non-penetrating stains (latex semitransparent, latex opaque, and oil-based opaque stains) on outdoor surfaces such as decks and fences are not recommended, as subsequent peeling and flaking may ultimately have an impact on durability as well as exposure to the preservatives in the wood. Consumers also need to be aware of the VOC changes that went into effect in 2005. These changes have had an impact on the coatings industry, and on product performance.
