Window Glazing

Worked in a hardware while I was in high school.

One of my jobs was to replace broken window panes in windows customers brought in for repair.

First time I was given this job, had brown pants before I was done, but you learn.

It was a learning experience for a 16 year old kid, but I survived..

Biggest part of the job was removing the broken glass and old putty to prepare window for new glass.

One you get the hang of it, reglazing a window pane is a piece of cake.

It is a skill that requires time to acquire, but is not difficult.

Today, I would not use glazers putty, but rather something like 3M5200 or 3M4200 which is easier to remove later, if necessary.

Trying to fit a plastic triangular piece into a sash, then having to glue it in place will not only double the work, but also not provide as good a seal just glazing the window pane into the sash.

YMMV.

Replacing the glass isn't a big deal, although since I'm working with restoration glass, it's a bit of a pain and expense.

Never said it wasn't, I've done it plenty of times before, but when you're talking about scraping down a dozen windows and probably close to 60 individual lights, that's when it becomes a pain.

Since the glass is all set in a bed of silicone, it's already sealed in place, there's no air exchange with the outside, this is being done for purely cosmetic purposes. I don't want to have to go back every couple of years and re-do it over. Besides, it's not especially difficult to miter corners, we do it all the time for picture frames, etc.

Did you perhaps see a "This Old House" episode where they were doing exactly what it sounds like you are facing?

They used a Fein Multitool to clear out all the old glazing which sure eliminated a lot of the mess.

Why use silicone?

There are so-------------------o many better sealants out there at relatively the same cost.

IIRC the plastic/PCV that you are speaking about is used on aluminum windows, it snaps in place. If you have wooden windows I think you are going to have to put the putty/glazing back in.
