Building disinfectants, sanitizers & sealants:

This article series lists providers of biocides, disinfectants, sanitizers, fungicidal sealants to reduce moisture uptake and retard future mold growth.

From Anabect to Zep including household bleach mixtures, this article series offers advice on cleaning mold found on surfaces of un-finished wooden building materials such as framing lumber (rafters, floor joists, wall studs), and building roof, wall, and floor sheathing such as plywood, tongue-and groove pine boards, and other structural wood surfaces in buildings.

This article includes expert quotations from Berry, Block & Morey, providing the the definition of Biocide, Disinfect, Sterilize, Sanitize, Sanitizer, the requirements for fisinfection & biological decontamination in buildings, and a description of the properties of classes of disinfectants: Glutaraldehydes, Iodine and Iodine Compounds (Iodophors), Phenolic Compounds, and Quaternary Ammonium Chloride Compounds (Quats) with comments on how they are used in buildings.

We have no financial interest in any of these products. This data was discovered by internet search. We have no independent scientific data as yet regarding the effectiveness, toxicity, chemical composition, nor durability of these products. Producers of mold remediation products are welcome to Contact Us by email (please, not by telephone) to suggest product listings, website technical content, or technical corrections. Items are listed alphabetically, not in any special order of recommendation.

Watch out: do not rely on disinfectants, sanitizers, or sealants as a substitute for actual physical washing and cleaning. It is important to physically remove contaminated materials or mold from buildings. Use of sprays or sealants alone is not reliable and is never a substitute for actual cleaning.

Watch out: Be careful using bleach: it is a powerful oxidant and should not contact skin or eyes; never mix bleach with ammonia - the result will be a release of dangerous chlorine gas. Watch out also that the use of bleach on most porous materials is likley to cause discoloration or loss of color.
See MOLD CLEANUP, BLEACH for more advice.

Watch out: reliance on ozone generators is not a safe reliable way to disinfect a sewage contaminated building. If you or your contractor are thinking of using ozone generators in the building,

Requirements for Disinfection & Biological Decontamination in Buildings

Berry (ret. 2014) and Morey (2007) describe the process of disinfection and defines disinfectants,

The processes of decontamination and disinfection will be important to ensure the elimination of pathogens and organisms that were contained in the sewage or that grew during the period of contamination. Even concrete can be colonized and broken down by microorganisms if it is allowed to remain wet and contaminated by organic matter. Chemicals categorized as disinfectants are appropriate in this application.

A disinfectant may be defined as an agent that reduces significant numbers of pathogens on inanimate objects to a level below that expected to cause disease. Disinfectants may not kill spores, however, and, because some bacterial and fungal spores will always be present in the environment, it would not be feasible to attempt to kill all of the spores in an affected area. Emphasis instead should be placed on removal of the substrates, water, and organic matter needed for the growth of spores.

Choice of disinfectants depends on the degree of microbial killing required, the nature of surfaces to be treated, application safety, and the cost and ease of use of available agents. It is recommended that disinfectants be used in accordance with the manufacturer's instructions for use and dilution.

Classes of disinfectants and their common-use dilutions include alcohols (60 to 90% in water), quaternary ammonium compounds (0.4 to 1.6%), phenolics (0.5 to 5%), iodophors (75 ppm), glutaraldehydes (2%), household bleach (sodium hypochlorite, diluted 10%), and hydrogen peroxide (3 to 6%).

The advantages and disadvantages of each of these disinfectants are given in Table 3 [REFERENCES]
. For example, the use of iodophores or low-concentration chlorine compounds would require that little organic matter be present on surfaces, a condition that may be difficult to achieve.

Caution should be used in mixing some disinfectants. For example, mixing chlorine-containing solutions with ammonia or amine solutions will produce extremely toxic vapors, and could have lethal effects on workers or building occupants.

Of critical importance is "contact time". Contact time is the length of time that the disinfectant is permitted to work on the contaminated surface. The contact time must be at least 15 min before additional cleaning and removal of the disinfectant is undertaken. Some disinfectants, such as the phenolics and glutaraldehydes, leave a residue that continues to suppress microbial growth for some time after treatment.

Classes of disinfectants

Morey (2007) citing Block (1991) Morey elaborates on classes of disinfectants.

Glutaraldehydes: These agents display a broad spectrum of activity and rapid rate of kill against the majority of microorganisms. Glutaraldehydes are capable of destroying all forms of microbial life including bacterial and fungal spores, tubercle bacilli, and viruses. They are excellent sporicides and will not corrode most materials. Disadvantages include increased peroral, percutaneous, and inhalation toxicity, along with elevated eye and skin irritation.

Iodine and Iodine Compounds (Iodophors): These agents are highly effective, have broad-spectrum antimicrobial capabilities and exhibit some residual properties. Disadvantages include inactivation by organic matter, and vapors may pose a hazard to respiratory organs. Some formulations may stain porous materials an orange-yellow color.

Phenolic Compounds: These agents are stable (less inactivated by organic matter), broad spectrum (generally include antiviral properties), and readily available, and leave a residue. Disadvantages include substantially increased peroral, percutaneous, and inhalation toxicity, along with eye and skin irritation.

Quaternary Ammonium Chloride Compounds (Quats): These agents have a limited spectrum of activity but are capable of killing gram-positive bacteria and fungi, and of inactivating gram-negative bacteria and some viruses. Quats have a naturally pleasant odor, counteract offensive odors, and are excellent cleaners. Ammonium chloride compounds are safer to use than most other disinfectants, because they are less toxic and cause less irritation to the mucus membranes. Quats, when diluted for use, are low in toxicity and irritation. Disadvantages of this class of agents include the facts that they are neither sporicidal nor tuberculocidal and that many formulations exhibit poor results against gram-negative bacteria and some viruses. Also, these compounds are incompatible with anionic cleaners (i.e., mutual neutralization of disinfectant and cleaner) and with the dye blockers in stain-resistant carpet. - Morey (2007)
