Q.
I
have a Cedar wood siding black mould problem. I live in the forested hills
on a Southwestern exposure lot. I use a semi-transparent stain over Cedar.
Every year I bleach the mould in early spring. Every few years I stain
it. I've been told that the bleach does not kill the mould. Do you
have a permanent solution?
A.
Your first step is to have a
Certified
Mould Inspector: (1) use a
fiber optics inspection device to inspect: INSIDE your exterior wall
cavities for mould infestation; (2) take core mould samples of the
entire thickness of the siding; and (3) test
the air of your indoor rooms for the possible presence of high levels of
unhealthy mould spores. If mould
problems are not found in those 3 areas, then your mould problem is
probably confined to mould growth on the outside of your cedar siding, and
it can be dealt with by several wet sprayings of
Mould
Killer. If mould is growing
INSIDE your siding, it will need to be replaced. Either way, seal the
exterior after staining with a plastic coating spray to seal out moisture
that is needed for mould growth. |
