Now that the sash is primed, it's time to put in the glass. I want a good seal to the glass despite a not so good edge on the sash for the glass to sit. I put glazing under the glass in addition to the normal glazing over the points.
Here is a video of me putting the glazing under the glass.
Don't worry about using too much glazing, because it can easily be trimmed off later. You should make it an even thickness all the way around to reduce the risk of breaking the glass.
You have to be careful when the glass in squeezed down on the glazing. Press the glass into the glazing in small, even amounts around the entire edge. Go around the edges several times until the glass is pushed down into the glazing.
The lower sash is a special problem. The top rail of the lower sash is not a rabbit edge, but a slot. The slot is filled with glazing, then the glass is pressed into it so it makes a complete seal over the glass edge. This step is not fun. The old hard glazing is hard to clean out of the slot. The slot must be the perfect size to allow the glazing to squeeze out when the glass is pressed in. Here's a video of me performing this step.
After the glass is pressed onto the underglazing, the points are installed.
The original points were flat diamond shapes. The replacements I used are the regular glazier points from the hardware store. I don't know how the flat ones were installed, but the new ones have flanges on them to allow a bent putty knife to be used.
Here's a video of me pointing the glass.
Then the outside edge is glazed. This is covered in so many threads and blogs that I'm not going to go over it here. I've seen some pretty bad demos of this step though. One bad one comes to mind is from the home improvement TV show 'Rehab addict'. That lady has no idea how to glaze a window. She just smeared it along the edge with her fingers then claimed to be an expert like everything else she does.
Here's a video of my brother doing it. He's not the fastest, but it looks good.
The glazing will have to dry and set for a loooong time before it can be handled without putting finger marks in it. How long? Well I would wait at least a month then paint over it. Even after several months, if I pick up a sash with my fingers in the glazing, it will dent.
