    Re: Mold Prevention coatings applied during new construction

    In contradiction to the chemist's almost unbiased opinion. The
    simple fact of the matter is that EPA reigistration is of great
    importance to anyone who would consider having a chemical in any way
    applied to their home. EPA registration is very costly and requires
    very stringent testing on all claims made with such a product. All
    products that receive EPA registration go through extensive efficacy
    testing and must prove what they claim before their producs can
    recieve EPA registration. The EPA does assure the public that all
    products EPA Registered work as their labels claim and are safe to
    humans and the environment if used in accordance to their label.

    I do agree with your opinion on Microban and have worked with the
    Aegis product. The Aegis product raises concerns with the methanol
    contents, however, at application strength the product is very safe.
    I hav worked with Envirocare and I can no longer reccommend their
    product after several failures and the tests results that I have
    recieved from the University of Oregon. I had several products
    tested: Envirocare, Protective Coatings Croup, Aegis, Microbe Guard
    and Fosters. The test results that we received from two independent
    labs agree almost exactly. Envirocare does not work, Fosters and
    Protective Coatings group was marginal and Aegis and Microbe Guard
    came out the best. Both labs agreed that Aegis and Microbe Guard
    were very effective with kill rates of 99.9% after 30 and 60 days.
    We were certified E-coat applicators for sometime and we have been
    mislead by their claims. In our market, we come across most of the
    competitors and Envirocare is the only one that I would run away
    from. Stating FACT, the owner of Protective Coatings Group used to
    be one of the owners of Envirocare. His brother in-law is now the

    We have checked warranty laws in most states, and what we found out
    is that you should never do business with anyone who is based out of
    Florida. Why? Florida law prevents companies and individuals who
    live outside Florida from collecting bad debts from Florida
    residents. That is why O.J. is there. If you owe someone money, you
    go to Florida where the State protects you. So what good is any
    warranty when the manufacture is based in Florida. It is only as
    good as the paper it was written on.

    We would all benefit from checking the facts out for ourselves. I
    can only reccomend that you contact the EPA directly and ask them how
    important EPA Registration is. Federal Law states only EPA
    Registered Pesticides can make claims that they Kill, prevent,
    eliminate or destroy mold, fungus or micro organizisms. I know this
    for a Fact!
