E,YIAIERIAUi Preservolive ABOVE GROUND Preservolive Rebnfion level The Pressure-Treoted TRANSITION One full year efter the voluntary ban on Chromated CopperArsenate (CCA) went into effect, it's safe to say that the surplus of CCA-treated lumber has been exhausted, and alternative materials now fill the racks at your local lumberyard. That makes it more important than ever that you understand the new pressure-treated lumber and how to use it to your greatest benefit. Most of the new "envilonmentally friendly" pressuretreating chemicals are copper based,just like CCA.The difference is that these new chemicals do not contain A Production of CCAtreoted lumber stopped o CCA such fierce criticism. inorganic arsenic, which is the ingredient that brought yeor ogo.

Both of these ffeaunents work like CCA in that they eliminate wood fibers as a food source for insects and fungus, which in turn contributes to wood decay.And all indications are that these ffeatments are as effective as CCA in preventing decay for many decades.

KEY DIFFERENCES Despite the similarities between new pressure ffeaffnenb and the old CCA, there are a few important differences to take note of. Cost -The new stuffis going to cost you about 15 to 20 percent more.This is due to the increased copper content.The new chemicals, lacking the inorganic arsenic of CCA, rely almost entirely on copper as the fungicide and pesticide. Copper is expensive, so the cost of the lumber has to reflect that. Varyrng Grades - The second difference is that not all pressure-treated lumber is created equal these days. In the past, the relatively low cost of the CCA chemical made it possible for manufacturers to pump every board full of the sruff. Now, because of the higher cost of new chemicals, manufacturers are a bit more modest with is application. The key is to check the end tags ofthe boards to ensure they are rated for your intended use (Sidebar at leJt). Corrosion Danger - The most important difference, though, is that new chemicals are much more corrosive than CCA. So the hardware that worked fine in CCA wont stand up to the new chemicals.That means hardware selection is essential to the longevity of your outdoor projecs.To he$ sort that out, we've put together a guide for selecting hardware to be used with pressure-treated lumber that begins on page 86. 84 woRKBENcH D FEBRUARy 2005

Galvanized - One important point I learned while shopping for nails and screws is that "galvanized" and "hot galvanized" are nol the same as "hot-dip galvanized."

The thick zinc coating that results from this process commonly clogs the threads and the recesses in the heads of the screws, so several screws in every box will be unusable. tests have confirmed the corrosion-resistant performance of these screws.Your best bet is to look for screws that offer a warranty and specifically state that they can be used in pressure-treated lumber. 86 woRKBENcH ! rEnnuanv 2005
