How to Keep Mildew from Coming Back
LESLIE: Now we’ve got Joe from Maine on the line who’s dealing with some pesky mildew that doesn’t want to go away and stay away. Tell us what’s going on.
JOE: I was talking about a shower thing and I seem to be – they have two parts. And we put the caulk in there, we take it out because it’s getting mildew behind the wall and stuff. I used Mean Green; it took it out and stuff but it keeps coming back about a month later. A customer keeps calling back, another one. And then sometimes with mildew on the porch here and we clean it with this Mean Green, it works but it seems to be seeping through. So I didn’t know if there was some kind of (inaudible at 0:05:54) or remedy that is out there so the (inaudible at 0:05:57) and this and that – that’s easy to use and has a chemical and everything else and stuff.
TOM: Now, is there caulk at the seam, Joe?
JOE: Yeah. Just in the bottom half and stuff. But I mean isn’t there a chemical that would cut it completely, that once you caulk it that it won’t seep through or …?
TOM: Well, no, because what happens is the condensation occurs from the surface.
Now, in terms of the caulk, there are caulks that you can use that have mildicides in them. In fact, DAP has a line with a product inside of it called Microban, which is very effective at stopping mold from being able to grow on the surface. So it’s a combination of trying to dehumidify as much as you possibly can and then using the appropriate products. So, in your case, that would be probably to remove and replace that caulk and then to add a timer to the fan. Otherwise, it’s going to probably keep coming back over and over again.
Hope that helps you out and thanks so much for calling us at 888-MONEY-PIT.
