Shopping at my local Woodcraft, I was torn between these Polypropylene Glue Spreaders and the typical horsehair brushes, the ones with the metal handles and about a 1/2″ of horsehair. With all those fibers, the horsehair has more surface area, which equates to more glue on the brush — but they’ve only got a few uses in ’em till they’re just too gooped up, and then they hit the trash can. These plastic glue spreaders, on the other hand, are reusable with most woodworking glues; just let the glue dry and it’ll peel right off.
They measure about 5” long with about an inch of tip. The flexible tip spreads glue evenly, kind of like a miniature putty knife, and you can cut the tip to meet your needs. There’s a small hole at the other end so you can hang it from a small nail.
Made in China, the glue spreaders come in a set of six, colored red, yellow, and green. Woodcraft sells ’em for about $4, and they’re also available from other stores online. They’re a good deal, but I’d recommend ’em in addition to the horsehair brushes.
