Oxidative Mold Remediation
It is estimated that property damage and devaluation due to mold contamination exceeds $3 billion per year. Accordingly, builders and property owners are seeking effective solutions to protect their investment from damage. To address these concerns, new biostatic antimicrobial technologies are being deployed to combat mold contamination.
Mold contamination has become one of the hottest topics among builders, property owners, restoration companies, boating manufacturers, insurance companies and personal injury lawyers. According to the Insurance Information Institute, mold related insurance claims have become a multibillion dollar challenge for the insurance industry, and warranty costs relating to mold claims continue to grow. For personal injury lawyers, mold is considered the hottest environmental issue since asbestos. For health care professionals, the effects of mold exposure range from no response to life-threatening conditions. In response, insurers are limiting or eliminating mold coverage, builders are facing increasing costs associated with litigation, and homeowners are caught in the middle with only limited recourse.
Mold is both pervasive and resilient. It is one of the oldest living organisms on this planet. For centuries man has harness its benefits and strived to eradicate its existence. In fact, one of the fastest growing industries around the country is the mold remediation industry. Protecting properties from mold damage is a multibillion dollar a year business. However, mold has proven to be a stubborn adversary. Industry professionals have found traditional antimicrobial disinfection methods ineffective in removing and inhibiting mold growth. In response, new technologies and techniques have been introduced to specifically combat mold. Until now, builders, healthcare providers, manufacturers of textiles, boating materials and other products created for moisture prone environments have had no durable and safe solution for their industries.
Inhibiting mold growth is challenging because fungi are very adaptive. They can thrive in a wide range of environments and when conditions are no longer hospitable, they can survive for decades in a dormant state. Antimicrobial disinfectants are effective in controlling mold in its growth state, but are largely ineffective when mold is dormant. Antimicrobial chemicals work by leaching or absorption into the microorganism. Once inside, they poison the microbe or otherwise interfere with its metabolism. This process is considerably less effective on dormant mold. As a result, mold easily survives the assault.
Initially, the chemical industry responded to the challenges of mold prevention by adopting antifouling paints used in the marine industry. These coatings contain antimicrobial chemicals or heavy metal poisons that slowly volatilize or leached from the coating surface. While this leaching process is effective for a period of time, it is not a permanent solution, and it creates it own environmental exposure concerns. To address the requirement for long-term antimicrobial performance, stability, and environmental safety, biostatic coatings have been introduced to the mold remediation industry.
Biostatic coatings provide a durable antimicrobial effect, but they do not employ poisons, heavy metals, or volatile compounds. Biostatic coatings permanently bond to both hard and porous surfaces. Upon bonding to a surface, the biostatic antimicrobial coating inhibits microbial growth by destroying the cellular wall of the organism. As a microbe comes in contact with the treated surface, biostatic (lipophilic) molecules penetrate the cellular wall. Once the cell wall is compromised, the organism dies. This physical killing process does not wear out or employ poisons or heavy metals therefore it is durable and environmentally safe. Further, microbes cannot build up resistance to this antimicrobial process.
Because of the unique characteristics of biostatic coatings, they have become the safe, effective, and long-term solution to inhibiting mold growth.
History – Biostatic coating technology was developed during the 1970’s as an advanced antimicrobial agent. Due to toxic stabilizers, the technology was only suitable in the manufacturing industry. However, in the late 1990s a new biostatic chemical formulation was developed which removed the toxic stabilizers from the formulation. Today, biostatic formulations are water stabilized allowing for safe residential and commercial use. They are proven to be non-toxic, environmentally safe, and pose no known exposure hazards.
How They Work – The biostatic molecule is comprised of two parts – a polymer foot attached to a long chain of carbon-based molecules. When applied to a surface, the polymer foot covalently bonds to the surface while the carbon chain points away from the surface. In effect, the biostatic coating resembles a series of needles permanently attached to a surface. Through ionic attraction, microbes are drawn onto the biostatic molecule. Upon contact, the long chained molecules of the biostatic coating penetrate and burst the cell membrane of the microorganism. Without the containment of their cell wall, microbes quickly die. The biostatic coating never dulls or wears out.
Environmentally Safe – Because biostatic chemicals do not employ traditional antimicrobial poisons or heavy metals, they are environmentally safe. Biostatic coatings are stable and do not leach, outgas or volatilize. Their antimicrobial performance is achieved through a physical killing process. Accordingly, no toxic or poisonous compounds are present.
Antimicrobial Performance – The antimicrobial performance of biostatic coatings has been proven effective in test after test against a wide range of gram positive and gram negative bacteria, fungi, and algae. The antimicrobial benefits of biostatic chemicals have been used for decades in many industries. Today, biostatic technology is being widely used in the building and mold remediation industry as a safe and effective fungal inhibitor.
EPA Registered – The EPA mandates that all antimicrobial agents (including mold inhibitors) be registered. To achieve registration, the EPA reviews performance data, environmental safety data, and human exposure data. The registration process requires years of test documentation to ensure public and environmental safety. Several biostatic products have achieved EPA registration, however, only one water-stabilized version has been approved for general use (non-manufacturing).
Biostat-500 is a new breed of bonded antimicrobial coating technology. Biostat-500 is a professional grade biostatic treatment that inhibits damage and deterioration caused by bacteria, fungi, and algae growth. It is EPA registered for use on a wide range of building materials including wood, concrete, brick, and plastic.
Product Description – Biostat-500 is a concentrated, water based biostatic formula designed for the mold inhibitor industry, structural remediation industry, and the commercial cleaning industry. Biostat-500 is an EPA-registered microbiostatic disinfectant that provides long term antimicrobial performance on a wide range of approved surfaces. In addition to its outstanding biostatic properties, Biostat-500 incorporates a stabilized quaternary disinfectant. Unlike other quaternary disinfectants which quickly leach from surfaces, Biostat-500 has molecularly bonded the quat to a polymer molecule. This bonding stabilizes the quat for long term performance. This unique formulation achieves both exceptional biostatic and biocidal performance. Biostat-500 is a very durable, broad-spectrum antimicrobial which will control many disease producing bacteria, fungi (mold and mildew) and algae growth on treated surfaces. This proprietary and patented formulation contains no heavy metals or volatile compounds. Once applied to surfaces, Biostat-500 is chemically stable, non-toxic, it will not leach or outgass, and is environmentally friendly. It is safe to use on all approved natural and man-made surfaces and will not discolor fabrics or react with metals or natural surfaces.
