Abstract
The proper use of barrier coating technology as part of the mold and mildew remediation process is discussed, along with the properties the appropriate barrier coating should exhibit. Testing to confirm these properties is discussed, along with some interesting comparison testing on the need for pesticides to achieve mold resistance of the coating s film. Interestingly, the US-EPA has already established independent certified lab tested standards for barrier coatings, this is also discussed.
One of the newer hazards facing property owners and managers of residential, commercial, institutional, and industrial structures is mold and mildew infestations. Newer is used loosely as mold and mildew (M&M) have been around since the beginning of time. In fact, regulations for dealing with mildew are given in the Old Testament in Leviticus 13. Much has been written and speculated upon as to why this has become such a frequent issue in just the past few years, but this is not the topic of this paper. Nor are the potential health issues from exposure to M&M a topic for this discussion. M&M and their resultant health issues are here and here to stay if proper remediation steps are not taken. As the proper M&M remediation protocol is followed, coatings can play an important cost saving role in many situations. This paper will discuss the exact role coatings should play and the physical properties that are necessary for a coating or coating system to provide the desired long-term protection. Performance testing relevant to the use of coatings for mold and mildew remediation will also be discussed. The information contained in this article expands on that contained in an earlier article by the authors (Ref. 1).
