Will Wet & Forget Work on a Shaded Area?
LESLIE: Alright. Now we’ve got John in North Carolina.
Welcome to The Money Pit. What can we help you today?
JOHN: I’d like to ask a question about a product that is one of your sponsor’s, I guess: the Wet & Forget Mold and Mildew Remover.
TOM: Yes. OK. How can we help?
JOHN: OK. Hearing what you have said and reading the label on it, I’m wondering if it’s appropriate for my application. I have a second-floor balcony, which is supported underneath by floor joists that are pressure-treated wood.
JOHN: Alright? That is exposed to the point where it’s starting to get a little mold and mildew on it and I would like to remove that and then stain it. It had never been stained. It’s about three years old.
JOHN: I have the Wet & Forget product but a couple things about it – it said and you have said, as I’ve heard in one of your programs, that the direct sun is one of the activators for it and also that it kind of depends to do its work on rainwater. Well, in that situation, those joists underneath are always in the shade and the water that it gets is not direct rain but it’s just sort of bleed-through between the decking above.
JOHN: Also, it is a vertical application as opposed to a horizontal one. And in that situation, they say if it is not fully exposed to rainfall or is vertical, some assistance may be required. Can you give me some idea of what that means and if I’m just barking up the wrong tree in trying to use this product?
TOM: Well, I suspect when they say “some assistance might be required” means you may have to wet it down from time to time if it’s not getting the moisture that it needs to activate. Now, do you have any sun in this particular area or is it totally in the shade all the time?
JOHN: Well, there’s lots of sunlight in the area but because it’s underneath that deck, it doesn’t get any direct sun.
TOM: Yeah. Right. But I don’t think it has to get – it has to get sunlight; it doesn’t have to get direct beaming, the heat of the sun.
TOM: I’ve never – in all the times I’ve talked with these folks and interviewed some of the chemists, I’ve never heard that it has to be fully exposed. Because, frankly, a lot of areas aren’t fully exposed and secondly, a lot of mold and mildew and algae situations happen because areas are covered.
TOM: And so it’s always good for driveways and sidewalks and areas that get like that. And a lot of times, that happens because they’re under trees and that sort of thing.
So, I think it would probably work. I think it’s a low cost of entry for you to give this a try.
TOM: I wouldn’t do anything aside apply it and following label directions. And then if you find, after a week or two, that you’re not seeing much difference, then you might want to try to get into a situation where you perhaps wet it down from time to time.
JOHN: OK. Any problem with it on pressure-treated wood as a surface?
TOM: No, none at all. In fact, it’s supposed to work on pressure-treated wood.
TOM: Look, I used it on a porch that was completely covered by a roof.
TOM: And open on the sides but it had a total roof. And it did a great job.
JOHN: OK. Alright. Alright. Now, the fact that it’s a vertical surface, even though they say that that may require some assistance, that’s still, in your experience, a good application.
TOM: Well, absolutely. There’s a lot of photos I’ve seen of tests that they’ve done with the stuff on railing systems, for example, which are always vertical, where it seems to work pretty well. In fact, these guys are now working on a new product that’s going to take mold out of a bathroom. It’s specifically designed to work on tile.
JOHN: Oh, OK.
TOM: So I don’t know how they figured this out with the sunlight component but I’m looking forward to giving it a try, because it’s a constant battle.
LESLIE: And it’s a special formulation for the interior, as well.
TOM: Yeah. It’s a constant battle.
JOHN: Alright. Thank you, Tom.
