    Re: Mold Prevention coatings applied during new construction

    Posted by The chemist on 6/05/05

    Regarding Simix Clear:

    This type of product doesn't help builders with their mold-related
    challenges and liabilities. This is a high-load Ti02 (the whitening agent
    in typical found in any paint), that relies on UV exposure to activate a
    photocatalyst response. The theory is that it turns water and carbon
    dioxide into oxygen and glucose and is effective against bacteria. This
    is ONLY USEFUL IN DIRECT SUNLIGHT AND DOES NOT HELP WITH WALL CAVITY OR
    INTERIOR IAQ RELATED APPLICATIONS. Moreover... It's a young, unproven
    product in the field.

    One other note: Nanotechnology systems have admittedly been inneffective
    against mold spores. Certain enzyme technologies are making claims but
    nothing that they seem to be able to back up very well.

    ...The Chemist...

    The Chemist has spent 10 years researching and developing regulatory
    compliant technologies for use specifically in the new construction
    setting. His research and development has revolved around building
    envelope forensics and microbiological activity as it relates to indoor
    air quality. This focus of study has produced several economical and
    marketable systems for use in new construction. Information provided is
