How to Install Faux Stone on an Exterior Basement Wall

  • Transcript

    LESLIE: Cal in Colorado, you’ve got The Money Pit. How can we help you today?

    CAL: Well, I have an interesting question here. I’ve got a house with an insulated concrete foam basement wall. That’s where you put concrete in between foam. And I have taken the outside wall – the foam – and have scored it with 30-grit sandpaper to give it a rough edge. And I screwed on the 2-foot-wide by 8-foot-long extruded aluminum – or steel screen to give me grip. But I’m putting on fake stone or faux stone, as some call it.

    And my question is – after I’ve screwed on the screening and I’m putting on – I’ve been told to take a Type S mix, which is a limestone/cement mix, and use that as my scratch coat. And the question is: how soon – what is the longest I can wait before I put on the stone? If I try to do all the scratch coat first, which could be a day or two because it’s over 1,000 square feet, am I going too long or should I be putting – buttering up the stone and putting that against the scratch coat right away?

    TOM: I think that as soon as the scratch coat dries, you can go forward with the stone. But typically, most masons will do the scratch coat first and then do the stone thereafter.

    CAL: OK.

    TOM: I don’t see any reason that you can’t have it exposed for a short period of time.

    CAL: OK. So, we’re not worried about a day or two.

    TOM: No, certainly not. You kidding? The way construction projects go, a day or two is like nothing.

    CAL: OK. Well, thanks for the info on that.

    TOM: Alright, Cal. Well, good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
