Cartridge Caulk Guns

Cartridge caulk guns take pre-filled tubes, the format most sealants come in. This collection covers 10 oz cartridges and 29 oz quart cartridges, with ratchet rod and smooth rod models from 6:1 to 26:1 thrust.

Choose by material. For acrylic, latex and silicone, a 6:1 to 12:1 gun such as the 188, 101 or 150 is enough. For polyurethane, hybrids, firestop and construction adhesive, step up to 18:1 with the 250, or the 255 for 29 oz cartridges. The 290 (22:1) and 375-XSP (26:1) handle butyl, epoxy and mastic, and the 360-DT (12:1 / 26:1) switches between two ratios on one frame. Pick the lowest ratio that moves your material comfortably, as our thrust ratio guide explains. New to caulking? Start with using a cartridge gun for beginners.
