Guy upstairs did a crappy remodel of his bathroom. His shower leaked and eventually we had a HUGE mold problem. Remediation was done but we wanted to make sure there were no residual mold particles taking root anywhere in our home (small, 2-bedroom condo). We used this product and sprayed for 1/4 of the recommended time. Horrible residue left all over everything. Horrible smell. I looked up the ingredients of this stuff (Concrobium) and they have TERRIBLE side effects, of which I’m suffering from right now. I’m SO pissed.
