An Alternative to Putty: Mitered Moldings
Applying a smooth, perfect bead of glazing compound is fussy, time-consuming work. So when good looks matter, consider wood moldings rather than putty to hold glass in place (1/4-in. quarter round works for most windows). Set the glass in place over a light bead of latex caulk (see Photo 2). There's no need for glazing points. To nail the moldings in place, you can carefully drive in tiny brads with a hammer or carefully shoot in brads with a pneumatic brad nailer. But the safest method is to use a brad pusher. A brad pusher is simply a metal tube with a sliding piston inside. Drop a brad in the tube, push hard on the handle, and the piston pushes the brad neatly into wood—with little danger of breaking the glass. Most hardware stores and home centers don't carry brad pushers, but you can find them at woodworker supply stores or online.
