Answer: None, putty is a mix of chalk and linseed oil, once the oil has evaporated that's your lot. Care must now be taken in the removal and you are using the tools that I would use, but try to be more carefull. I use putty mixed with fine powder filler (Polyfilla) makes it just that bit drier to use and sets hard quicker. Applying paint before putty is dry and the paint will go wrinkley. Watch out for glazing sprigs (flat, topless nails) holding the glass in place and dont forget to re-use them when you install the new pane.

Answer: Right on! I am restoring the paint and putty in the wood window frames of my 75 year old house. I have broken 3 for 3 so far. So I am going to try my router......very carefully in a free-hand mode, to see if that works better. There MUST be a better material than the old fashioned putty. I see that Dap has a new calk-like material in a tube. I will try it too. Seems like a silicone window and door calk should work too. It may be a problem removing the next time though. More later.

Answer: I am having the same problems as Bob, I have an 95 year old house and we are repainting, I tried the Speedheater infra red heat system and it takes the putty off but I've cracked the glass scrapping, I also bought that Dap stuff too, let me know how you make out.

Answer: Seem a few trade people do this: o Scrape out only the falling-out putty ---- ie, if you can easily remove it, replace it o Refill in with fresh putty o Otherwise just use sealant on older putty ---- force to remove WILL break the pane Had a window where a rose-bush had pulled the paint/putty away on the bottom. Sure enough it had created a 3" vertical-slot-channel for rot to set in. New window only ��25 so did it. The joiner matched both the inside & outside dimensions of the window, I got the old glass out but only after trashing the old frame. It took about 1hr, no joke, with a tiny screw driver to lever the putty out via the wood. If you go in via the glass you will crack it. Some was soft, still "linseed grainy", some was quite literally like concrete and took a slow scraping with a screwdriver to abrade. That was 55yr old putty, and some was stuck to the glass like glass-superglue, some was inseparable from the wood - particularly around knot-like areas. Very often the glass is worth more than the old frame (espec if rotted or hinges are old-style, seized, dropped or it is a leaded-glass pane). I re-used the pane just to see if I could, so a relative didn't have a board in it as it's a weekend. By the time you've bought a good overpaintable woodprimer, decent 2 part epoxy filler, and styrene wood hardener, you have probably paid for a new window frame :-)

Answer: I've removed the putty from my windows and used a heat gun to soften the putty. Still need to be careful but that has worked the best for me. I was successful removing the putty on four panes without breaking but then broke a pane putting in an extra push point. Now I need to find out the best way to put the new putty on. Any tips?

Answer: Use a heat gun but watch so you don't get the glass to hot you can get a scrap of tin to keep near the glass as you're doing this
