An EPA approved, zero VOC, mold and mildew Inhibitor for interior walls and ceilings
Caliwel Home and Office is a revolutionary, multi-patented, zero VOC, antimicrobial paint that effectively and responsibly resists the growth of mold, mildew, algae, fungi and odor causing bacteria. As a mold remediation tool, it will inhibit its re-growth for many years to come. As a superior surface treatment, it comes in white and looks just like a traditional architectural paint but cannot be color matched to other brands. It also guards against deterioration and discoloration caused by microorganisms.
Caliwel's unique award winning formula has three separate EPA approvals which required 7 years of testing. Unlike most antimicrobial products that contain pesticides or other harmful VOCs, Caliwel has no biocides, zero VOCs and is virtually odorless.
Caliwel utilizes as its active ingredient calcium hydroxide (hydrated lime), which is a highly alkaline naturally occurring mineral with the longest history of clean and effective use. It's an important component in pharmaceutical and dental products, supplements, as well as dairy, sugar and baking industries. (For more info about the benefits of hydrated lime, see side bar to right.) Caliwel's proprietary Bi-Neutralizing Agent (BNA) safely prolongs the neutralizing power of calcium hydroxide while resisting degradation long after it has been applied.
Caliwel Home and Office antimicrobial paint is a full substitute for conventional architectural latex paint. It is water-based, quick drying and easy to apply with a brush, roller or sprayer and takes effect immediately within minutes of application. Use on properly primed gypsum drywall, masonry/concrete, plaster, wood interior walls or spray foam insulation. It comes in a flat white color and covers 250 square feet per gallon. Two coats are recommended. Ideal for all interior residential, retail, healthcare, eldercare and educational facilities, manufacturing and warehouse facilities.
Caliwel also provides excellent fire resistance. It has a flame Spread Index (FSI): 0, Smoke Developed Index (SDI): 0 and Class I FSI 0 - 25. Caliwel BNA has been tested under Protocol: ASTM E84-99 “Standard Test Method for Surface Burning Characteristics of Building Material” NFPA 255, ANSI/UL 723 and UBC 8-1.
The growth of mold can be damaging to your building and your health. Whether you are building new or remodeling an old structure, removal of pathogens and preventing their return is of utmost concern. It can be very expensive to mitigate and remediate old surfaces, not to mention the cost of health care to those affected by pathogens. Caliwel with BNA is a proactive approach to creating and maintaining a cleaner indoor environment without the use of biocides, pesticides or toxic chemicals.
Caliwel also makes two other products: Caliwel Industrial Mold and Mildew Inhibitor for behind stud walls, crawl spaces and basements and Caliwel HVAC only for professionals to use inside HVAC ducts. Please call 800-405-0222 for more info.

At last, we've finally found a natural alternative that will not only mitigate your existing mold and mildew problems but will protect your home or office or warehouse for years to come. Unlike almost all mold killing products on the market from Microban to Tea Tree or Thyme oils to Concrobium, this product contains no VOCs, triclosan, pesticides or any strong odors. Now you don't have to worry that any potentially hazardous ingredients will leach out into your living space. Note: While this is a non-toxic product, it has a pH of 12.4 which should be applied with gloves and eye protection. Once it has dried, it will not react to your skin.
