Optimal Indoor Air Quality
Four of the primary sources of poor indoor air quality in a residence or building are: 1) allergens, such as animal dander, dust mites, pollen, mold, and mildew; 2) retained moisture and dampness in architectural elements, fabric and furnishings; 3) residual odors from smoke, appliances, personal care items, HVAC systems and cleaning agents; and 4) volatile organic compounds (VOC's) emitted by aerosol sprays, wood preservatives, air fresheners, graphics and crafts products, and inexpensive, artificial building materials. All of these respiratory irritants are fostered by the use of carpeting, including the padding and adhesive, while moisture and VOC problems are also often commonly associated with wood and tile installations.
Acid-stained concrete flooring is different in this respect: it can be installed with little to no VOC's, and overall, it fosters optimal indoor air quality. This is because acid-stained flooring allows moisture to readily evaporate; provides no place for dust mites to hide or mold or mildew to grow; cleans easily; and does not store odors. Furthermore, most good concrete sealers available today contain absolutely no harmful vapors, odors or residues.
What's more, acid-stained concrete flooring and decorative concrete overlays may be installed using radiant heating beneath the surface so as to provide a slow, steady, "clean" source of heat to a home or building. This type of heating stabilizes the clean air environment fostered by acid stained concrete flooring - contrasting dramatically with forced air heating systems which circulate dirt, dust, pollen, odors, and germs every time the system is activated, and require the regular change of filters, and cleaning of ducts.
