    Hi guys. Just wondering if any of you helpful dudes might know if silicone from a tube, the plumbing stuff, would stick to molding silicone? I'm hoping to use it to build up some areas of a mold I'm working on.
    Any advice on pros/cons would be much appreciated.
    Cheers - Chris

    Sure does, I do it all the time to fill in undercuts. If tour moulding silicone is tin based, you can go over it with more moulding silicone. If your using a platinum based moulding silicone, make sure you use your plumbing silicone last and after the moulding silicone has completly cured otherwise the platinum will inhibit.

    Thanks again fettster. Just used it and it worked a treat. It's a fairly lumpy model, so I was able to create dams and such where I needed to. Should be a great way to save a couple of bucks too, using the tin silicone only where I have to. Thanks again.
    Cheers - Chris

    Hmmm,I was always told that it wouldn't.But I suppose that depends what kind of silicone it is?Platinum or tin based?

    It also sticks to an insane level on those roll up keyboards, and silicone covered phone hand sets, as does Silly Putty!


    Just ask my ex boss!
