Silicone release agent?
At work, they've been draught-proofing the old windows. It seem that this has involved squirting a big
bead of silicone along each mating surface, then closing the window until it goes off. Good (if temporary-feeling) idea for some locations as it moulds to the right shape. Once cured, the silicone stays on the one face. They didn't do my area, so no chance to find out how it was done, but they must have used some release agent on the 'uncoated' face for this to work. Any idea what they might have used as a release agent? |

Any idea what they might have used as a release agent? When I saw something like this done, they put tape down one surface (e.g. insulating tape), squirted silicone down the other face, and closed for a few hours. Opened the windows, removed the tape. The windows were metal casements, and I think they put tape on the frame itself and silicone onto the opening window. It did not work very well simply because the frames were dirty and paint somewhat flaking before they started - and that was not properly addressed. -- Rod |

My father refused to buy new windows, saying, "They will outlast me" Turned out he was right on that score. I had to stay in his house for nearly a year and got ****ed off with watching the curtains billow out at 90deg and freezing to death. Waited for a reasonably mild day and started early morning. Wrapped the edges of the opening windows with cling film, put a bead of silicone around the frames, closed the windows to almost shut and left them like that for the rest of the day. When the silicone was about set, off with the cling film and they worked a treat. |

I've found cling film pretty useful when using wood filler on an edge too: Cover a piece of timber/board/whatever in cling film, clamp to an edge, stuff the filler into the gap, then peel off, leaving a straight finish. |

It wouldn't take much not to release to have the window siliconed shut and working out where that was to slice it through with a blade could be a right begger... -- Cheers Dave. |

I think I'm with you Dave, although there's always a case for empirical evaluation(!) so I'll try to have a go at some of the suggestions here and see what works best. Clearly it would be a lot simpler to just seal things shut, but that might not be too useful for a door, for example (!) In principle, it could be a useful way to draught proof an irregular gap that's not suitable for a weather strip, though I suspect it would need a bit of ongoing maintenance. I was thinking mostly about temporary measures in some draughty places (I have plenty) pending doing a proper job. |

The air cure stuff as used in sealant cartridges and which smells of vinegar sticks to almost everything when it sets. The two-pack stuff (RTV, short for room temperature vulcanisation) doesn't stick to anything, hence is used for things like dental moulding. Silicone oils are not particularly good lubricants for metals (compared to mineral oils) but are very good on most plastics. |

Scrape both mating surfaces. There is a primer for the side that is to get the silicon but I am not sure it is needed. (pretty sure it is expensive though.) Apply non stick washing up liquid grease or whatever. Run bead of clear silicon down rebate. Close window. If you have a choice of closures use the sightly open notch on the lever. Next day give the casement a judicial going over. If it is too fast, inset thin blade along joint. |

You can get other sealants that are over-paintable. (e.g. http://www.marinemastics.com/marine-flex.html but beware they are better glues!) Phil. |
