Re: Mold Prevention coatings applied during new construction
Posted by Aspects on 11/01/04
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
owner.
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!
