Just how low the VOC level needs to be for a given product to qualify for inclusion in GreenSpec depends on the product category. For most products, we require certification to California’s health-based emissions standard, CDPH Std Method v1.1 standard (also referred to as California Section 01350), which tests a product’s resultant VOC concentrations in the space after a given period of time. For wet-applied products like paints, caulks, and adhesives, we still also look for VOC content instead of, or in addition to, verified low emissions; this is because emissions testing doesn’t adequately test initial offgassing, and VOC content is currently the only widely available proxy.
Tobias Green Interior Wall Finishes are non-toxic, odor-free, virtually VOC-free, trowelled-on wall finishing products. The limestone-, aggregate-, and-water-based products can be used as an alternative to paint or plaster and applied to most building substrates. The finishes are available in a variety of colors and can be applied to provide various textures. They are designed for the professional plastering contractor and are sold in 1-gallon and 5-gallon containers through a national sales network of building supply distributors and independent sales representatives.
Lime plasters can have slightly lower embodied energy than portland-cement-based plasters, and they don't include petroleum-based ingredients, as acrylic plasters do. Integral natural pigments obviate the need for painting.
Products listed here include natural lime plasters and wall coatings made from ingredients such as clay, sand, and cellulose.
Repairing old plaster is preferable to material-intensive replacement, so some plaster repair systems are also included.
Decorative finishes are typically high-grade, multicolored and/or textured coatings for interior and exterior applications. Textures and colors are achieved by proprietary mixtures of pigments, oils, and inorganic fillers.
Such products offer a durable and environmentally preferable alternative to common vinyl wall coverings, which offgas plasticizers and pose heightened health risks during a fire or end-of-life incineration.
Products listed here are waterborne and have relatively low-VOC content.
