    Re: Mold Prevention coatings applied during new construction

    As long as builders build sloppy structures, no silver
    bullet will save them.

    1) Improperly installed window have nothing to do with these
    wonder products that really don't work.

    2) Poor HVAC design/installation has nothing to do with
    these wonder products that really don't work.

    3) Poor construction sequencing has nothing to do with
    these wonder products that really don't work.
