Steve shows his students at the July 2022 Total Window Makeover Course in San Antonio, how to glaze a window sash, giving commentary along with every step.
Glazing old sashes is a nightmare. The old glazing never comes out uniformly. In some places, where the wood is water damaged, the glaze just pops out, but in other places, the glaze is hard and difficult to extract without damaging the rabbet. I’ve tried every tool. Flexible scrapers, heat guns, multi tools, and utility knives. It’s never easy. Especially when you reglaze the windows in place.
