RAY: I keep getting mold in my garage. It’s an unfinished garage and my dog stays out there a lot and I keep getting mold around the door frames and on the floor. How can I clean it and keep it from coming …?
TOM: (overlapping voices) On the floor? On the concrete?
RAY: (overlapping voices) Yeah, on the floor. It’s a concrete floor. Yeah.
TOM: That would be very unusual because mold doesn’t grow on inorganic places like floors.
LESLIE: But it does grow on dust and dirt.
TOM: Well, that’s true. Well, what you need to do is you need to wash everything down with a mildicide. I would use a bleach-and-water solution or I would use a commercially available mildicide and the common mistake is that people sort of scrub this stuff away but they don’t leave the mildicide product on the surface long enough for it to really do it’s job. You need to spray it on and let it sit for 10 or 15 minutes so it really goes to town and kills all of the fungal spores that are left behind and then you can clean it off.
TOM: And the other thing that I would do after that is I would use a bathroom-type paint that has a mildicide in it. I would prime the surface and then I would use a mildicide-based paint on top of that and that will help slow this down.
LESLIE: Mm-hmm. What about an epoxy coating for the floor?
TOM: Yeah, that as well. That’s a good idea. Because it makes it easier to clean.
RAY: Well, thank you so very much. What would the – what’s the ratio of the …
TOM: Bleach to water?
RAY: … the bleach to water?
TOM: I would probably go about 20% bleach.
RAY: Twenty percent?
RAY: Thank you so very much. I appreciate it. Love your show.
TOM: You’re welcome, Ray. Thanks so much for calling us at 888-MONEY-PIT.
