Putty or beading/quadrant?

[John Brown]

I need to replace a pane of glass in a rather large casement window (about 1020 by 900 mm). It is not easily accessible from outside, so I'm planning on removing hinges and taking the whole unit out. Obviously I want to get it reinstalled ASAP, so either I use that fast setting putty substitute, or I was considering bedding the pane in putty (?) and then pinning some beading in place. The reason I don't want to use proper linseed oil putty is that I'd rather not wait a week for it to skin up before painting. Any advice gratefully received...

I do have a nailer/stapler, by the way. Which I think might be safer than me using a hammer, especially if I find an old mouse mat or something to use as a shield.

There's a modern putty-replacement, "Dryseal", which is much faster drying. It has other advantages over putty too.

I would personally take out the casement, putty the new pane with the linseed oil putty, put it back into place and pull it out again and paint it in a couple weeks time.

They call putty alternatives alternatives for a reason, they haven't stood the test of time like the traditional LSO putty has. Yes, it's a pain to apply if you don't do it every day and it takes a while to skin over, but you won't ever have to do it again in your lifetime if you do it properly.

I'll see how easy it is to get in and out, once I've jury-rigged some sort of crane arrangement hanging out of the fanlight. As i said, it's impossible to access the window from outside without scaffolding. Whole job is on back burner right now as we have family visiting.
