Putty removal
Our front door has nine funny-glass panes that we want to replace. The
wood partition between the panes on the putty side is very thin, dimensions about 18mm x 4mm. I don't know how to remove the putty without breaking this. My usual method, spatula and hammer, is almost guaranteed to damage the wood and involve me in some fiddly carpentry. Any suggestions? |
Putty removal
I found a long post online by someone who sounded as if he knew what he
was talking about. http://www.diychatroom.com/f4/removi...acement-30292/ (you have to scroll to the bottom) He said apply a mixture of linseed oil and chlorine bleach with the frame lying flat, for a day or so. Apparently the linseed oil will penetrate into the putty and soften it, while the chlorine attacks the calcite in the putty (which is made from high-calcite lime and linseed oil) and does something. Anyone tried this? |

Any suggestions? Sometimes works: Solid, thick block of wood, placed against most of the length of the wood partition. Smack wood block with hammer. The goal is to break the bond between the putty and the glass without breaking anything else... Thomas Prufer |

I realized that this is unclear just after sending... the smacking is parallel to the glass, i.e. the thick block of wood is pressing outwards from the middle of the pane. Thomas Prufer |

Anyone tried this? As it's summer down your way, that might be worth a try! I'd break the glass first and use the shards to prise the putty away from the wood. If the putty is still soft inside (and it's amazing how much of it is), it should separate easily |

Most of the putty was rock hard, except for a couple of panes that had obviously been replaced. Still, your suggestion is worth a try. |

I've even seen them (on the web) specially for putty and paint removal -- Chris French |
