While drywall is usually porous, plaster is not.
What this means is mold can and will grow on the drywall, and often times on both sides since it’s organic porous material; in fact, the rich carbon paperback that holds the gypsum together is the preferred food source, almost a buffet for Stachybotrys to grow, thrive and decompose given enough moisture.
If you have visible mold on the exterior of the drywall surface, it is almost certainly a larger amount of mold growth is present on the back of the drywall.
There are no products that can guarantee the successful cleaning of mold on the drywall due to the porosity of the material. The proper procedure has it cut off and removed.
Mold on plaster walls, on the other hand, is cleanable since it is not a food source, and not porous. Abrasive cleaning with the proper approved chemicals and surfactants can successfully sanitize the surface.
The mold typically feeds on your paint and dust. However plaster walls can contain paper backing and if moisture penetrates the back of the plaster, the walls will have to be removed and replaced.
You should always consult with a mold remediation specialist to ensure you can determine the extent of the contamination. Sometimes it can be much worse than it seems.
