Primo Tools Caulk Gun — Controlled Flow, Clean Stops The difference between a crisp silicone joint and a smeared one usually comes down to the moment you stop squeezing. A basic ra tchet gun keeps pushing after you let go, and that trailing ooze ends up on the tile, the tub, and your rag. This dripless gun solves it: the thumb release backs the pressure off the instant you're done, so the bead stops where you want it. Getting there, the 10:1 thrust ratio gives you smooth, even flow without fighting the trigger, so long runs of sealant stay consistent from one end to the other. It holds standard 10.5 oz caulk and silicone cartridges, and the durable frame is built to survive the bottom of the tool bucket rather than bend on the first stiff cartridge. It's the un-glamorous tool that quietly decides whether your finish work looks finished. Why Tile Pros Choose It Dripless: Thumb release stops the flow so the bead ends clean Smooth dispensing: 10:1 thrust ratio for even, controlled flow Standard cartridges: Holds 10.5 oz caulk and silicone tubes Durable frame: Built for daily jobsite use Cleaner finish work: Control where it matters most — the visible joint Stops when you do: A rare and underrated virtue in a caulk gun Pro tip: Cut the nozzle small and at 45° for a tighter, more controllable bead, and release the plunger a beat before the end of each run so momentum doesn't overfill the corner. Tool the joint while the silicone is fresh. Show more
