Sealing lead came...
A mate of mine has original crittal windows (1930's metal frame single
glazed) with real lead lite Georgian style panes. Recently in some of the driving torrential downpours, it has started leaking apparently through the pane joints. Is there a recommended / easy way to restore a seal to these? -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

HI John If they're really 'real' leaded panes then the proper way to fix them would be to dismantle them & re-make them. However - that's a lot of work. A 'quick & dirty' (but surprisingly effective) solution, where time, budget etc doesn't allow the 'proper' solution is this stuff http://www.captaintolley.com/ which is a very thin crack-seeking sealant, that will find its way into the existing putty and, once set, will form an effective seal... It'll probably need several applications, until no more is absorbed. I've used this on church windows, where sections have been repaired / replaced, but there's no budget to replace the whole window.

At the same time, a mechanical caulking of the lead flange by rubbing it down with a bone. However it's also recognised that doing this to old (brittle) lead is a bit of a fruitless task. In many cases, by the time the window has got to the stage of leaking, it's actually doing this through cracked joints in the lead. The only real solution at this point is to strip the glass apart and rebuild the panel with new lead (not actually too expensive, compared to cutting glass for a new panel). Captain Tolley's is good stuff though, and worth a try. |

Would wood hardener be any good as the creeping sealant? -- Ian |

As Andy says, it's not as good a solution as doing it the 'proper' way - but it's still effective... Adrian |

Ideal! Can't remember what the solvent is for the Captain's stuff - but you'll want to wash the syringes out between applications as otherwise they'll seal solid! - expect to make two or three repeated applications - wipe off the stuff immediately if / when it goes where it shouldn't, as it can cause staining of the lead and the glass Much easier if you can get the offending panels out and flat... but still do-able of you can't...

Yes - I know what you mean However, in later life, I have eventually learned that a well-planned and well-executed 'kludge' (if that's the word) is often more than satisfactory, and will probably more than see me out. Amen! Take it gently with the Tolleys and you'll be fine. The bottle comes with an applicator nozzle - but it's far too 'fast' for your application & you'll end up with it everywhere! Good luck Adrian |

Trying to re-solder a failed joint in an old panel is near impossible. Resoldering oxidised metal certainly is. Would it not work ok if cut with a knife each side of the crack, to expose clean lead? NT Trouble is , you very quickly get into 'diminishing returns' Ideally, you want a nice 'butt joint' between the two pieces of lead before soldering. If you have any significant gaps (more than a couple of mm) then you'll find that the solder will 'neck' in and look terrible. Again, in an ideal situation, you want solder to stick to the flat surface of the lead came. Andy's right, no amount of wire-brushing / sandpapering / wire-wool work will be effective. It's another step into the land of bodgery grin - but I've had some success with the two-part 'liquid metal' epoxies, which, once set, are pretty much indistinguishable from the original lead - and can hold things together if there's no funding for a 'textbook' (remove, dismantle, re-lead, re-putty, refit) strategy... Not ideal, but better than having the rain come in! I'm seeing a few of these recently - mid-1800's church windows, exposed to salty sea-air and the odd football / stepladder or, in one case, a flying pumpkin (it was Halloween!) Adrian |
