Miliput for window putty.

[plasticpigeon]

One of the things I hate about putty is how long I need to let it dry before painting. I've found this can be a good few weeks if the weather isn't great. Even then I'mnot sure modern paints are very compatible, as I've had the surface get very soft post painting and even crinkle. I had to repair some putty round a window I am restoring and decided to use miliput. I did one complete bead at the bottom of one sash, and repaired other bits where the puttu has fallen out. It is brilliant. It can be put on with a trowel just like normal putty, smoothed with a wet trowel or finger, and dries withinh a day. It is £3 for a small pack, enough to do the beads on one window perhaps so more expensive than linseed putty, but so much more convenient. Can anyone see any reason not to use it?

That's an epoxy putty. Will you be able to get it out again if you ever want to replace the glass? With linseed putty you just heat it up and it comes off.

I've tried heating very old putty and it is like rock! if the glass is broken anyway, i'm sure it is possible to get it out with a chisel, it isn't really very hard when cured.

Will it set as hard/ridgid as epoxy window frame filler? If it does you might have a problem with it cracking as the timber expands/contracts.

What about Butyl putty, is that suitable for exterior use?
