I've gotten the hard work done: picked off all of the old, painted over glaze (most of which FELL off!), & treated the bare wood, but am having a terrible time applying the new glaze. I'm pretty handy with caulk & a gun, but can't seem to get this to go right. Part of the problem is that the old was so damaged, I'm not sure what the new is supposed to look like: should the glaze extend out to meet the vertical plane of the wood, or just be a narrow bead joining the glass pane to the wood ? Or have I just gotten a bad tube of caulk? It is very stiff, almost like library paste. The very tip of the tube is triangular, but is rectangular just past the tip, so I'm not sure just how to position it. Any help would be greatly appreciated - sure want to finish up this maintenance nightmare before cold weather sets in. Thanks. Gail

 

Gail, it sounds like you have DAP33 window glazing in the tube. First question I have is how cold is it where you are? When the temp. gets below about 50 degrees (F), this tends to get pretty stiff. To get around that, keep the tube in the house (at about 70 degrees), which will keep it fairly loose.
To apply it, point the caulking gun into the joint between the pane and the wood. On the tip you will see that on the top (long side of the angle) the plastic extends slightly beyond the angle. Let that flap rest squarely against the pane, and the bottom edge against the wood. Move the gun at a steady pace along the joint you are caulking, and you should get a good bead. It takes some practice, so the more you do, the better the beads will look.
