Mold In Our Homes WEDI (SHOWERS)
In order to reduce the risk of infestation we must eliminate the environment and
conditions that are conducive to mold growth. To do this we must remove all gypsum
board (no matter if it is specially treated or not, they were also eliminated in the 2006
IRC from any wet area); secondly we must eliminate moisture penetration in those areas.
Simply put no gypsum, no water, no mold. If other surfaces or backerboard materials are
installed such as cementitious backer units or fiber cement boards, one need to know that
these are only water resistant but still absorp and pass water and especially water vapour
to the wooden construction where the real problem will grow. All these substrates need to
be waterproofed additionally. All seams, joints, penetrations as well. Mesh tape and
thinset adhesives do not waterproof any tile installation. Because this is fact, none of
these manufacturers covers the mold issue in the wooden construction with any warranty,
nor does any insurance company cover any contractor work regarding mold issues
anymore. This situation must be clear to everyone, otherwise this problem will not be
solved in any predictable and successful way or form. Another solution that the industry
offers can simplify the installations and eliminate the mold concerns in a most practical
and efficient way:
