Finishing Hotline Because there is no universal standard, some finish manufacturers, such as UGL, have created their own internal definitions as to what an environmentally sound finish is. This allows consumers to understand exactly what the company means by "green." of the planet: two concepts that sound good but whose meanings are clearly open to debate. Still others use the term green to mean low VOC coatings, while another group of companies use it to mean coatings made from natural materials, irrelevant of the VOC content. Let's look at a few common coatings and see how they stack up. I've listed them more or less from greenest to least green, but be warned: this is not a simple yardstick but rather a complex equation. In many cases, it is a judgment call as to which is really greener, and in some cases we are reduced to splitting hairs. The good news is that no matter what type of coating you like to use, there is probably a greener version of it. Another company formulates their coatings to eliminate anything that might cause any allergic reaction in sensitive people. To that end, they not only reduce VOCs and HAPs, but also other compounds, even inorganic ones, that could cause a reaction. (See sidebar, previous page.) Several companies, in fact, insist they make or sell products that have the least adverse effects on human health and the health Traditionally Green Finishes Some coatings are, and have always been, surprisingly green. Milk paint, for example, contains no VOCs or HAPs and is made of completely natural and sustainable ingredients. Natural oils, such as pure linseed oil and pure tung oil, also fall into this category. Waxes, at least in their solid state, also quality, since most of the ones we use are either plant waxes, like carnauba and candelilla, or insect waxes, like beeswax and shellac wax. However, most paste waxes, the ones that come in tins, contain some VOC solvent to make them softer and easier to apply. Finishing continues on page 62...
