Glazed and burnished units manufactured by Trenwyth Industries and distributed by Angelus Block are popular choices for indoor masonry surfaces. Glazed units are, of course, factory finshed and are VOC-free. Trenwyth burnished units (Trendstone®, Trendstone Plus®) have a factory applied sealant with low or no VOCs. Other precision and burnished units in high-traffic areas may benefit from a surface sealer to minimize soiling. Many water-based, low VOC products are available. |
The technical structure of these criteria are specific to stated materials — adhesives, sealants, paints, and coatings — and do not explicitly account for the absence of their use. Concrete masonry can provide indoor surfaces that do not necessarily need painting, thus no VOCs are introduced.
