You Don't Know Foam

摘要

The first time I saw a professional spray-foam gun was when my friend Andy pulled his Pageris gun from a green protective case to air-seal and insulate around a window he'd just installed. The gun had a larger can than those that dispense foam through a straw, and it offered far better control over the size of the bead. In addition, Andy didn't have to come up with a use for the other 90% of the can's foam that he didn't need on this job. I decided right then that I was done blowing foam through a straw. It took me much longer to learn how to maintain one of these guns, though.
