Re: Soda Blasting For Mold Removal???
Posted by David Hawkins on 2/04/07
I agree with Ryan. People have a tendency to knock the other guys
technology, such as carpet dry cleaners stating that "steam cleaning"
or hot water extraction will rot and ruin the carpet. This is very
untrue (having used both methods) unless the operator is sitting on one
spot, with the vacuum hose removed and TRYING to make this happen.
The point is that it is easy to think something from a point of lacking
in actual knowledge about the other guys approach. For example, it has
been stated in these posts that a 11 ph is caustic and implied is
destructive, "caustic". 11 is a very normal ph in many cleaning
detergents, that are used everyday for normal heavier cleaning needs on
household surfaces. Granted it is a higher ph but not at all uncommon.
Also while I can see how blasting could be possibly a problem in homes
lived in, although if the room is properly prepared and the residue
cleaned and removed, it would seem not to be a problem, but the big use
for this is in New Orleans in homes largely opened to the air and heavy
water contamination for many months and literally have to be gutted and
rebuilt. As stated the blasting process is to REMOVE the mold spores
from the studs and inner structure. There arent going to be wallboard,
floorcovering, furnishings etc to protect.
Once the hard surfaces have been cleaned of mold, then all surfaces
can be cleaned chemically and if the home is not open to the outside
air can have the air filtered by a machine, or otherwise it will just
be carried into the normal air exchange with nature.
As stated, there is mold in the air. The job of remediation is simply
to remove excess mold, eliminate the moisture factor and prevent
regrowth. Testing does not regulate the amount of mold, simply to
determine if it is in excess of outside mold levels indicating a
greater presence of mold inside the structure.
In New Orleans the minor damage was fixed long ago, the heavily damaged
homes from water need massive rebuilding and just need the mold removed
from the studs and surfaces within the wall areas basically.
We need to look at things realistically and not just as portrayed in a
book or most theoretical view, and yes I am certified and have learned
from a book as well.
