Squeezing a manual caulking gun all day is hard on your hands, and the bead goes uneven as you tire. A cordless caulking gun pushes the sealant for you at a steady speed, so you get a neater bead with far less effort.
What it's good for
- Windows, doors and frames
- Baths, showers and kitchen worktops
- Skirting, coving and trim
- Roofing, guttering and outdoor joints
- Adhesive work on panels
Cartridges and sealants
Our cordless caulking guns take standard 300 ml cartridges. They work with silicone, acrylic (decorators') caulk, adhesives and sealants. Check each listing for the products it's designed for.
Features that matter
- Speed settings. Low speeds for detail work and corners, high speeds for long runs. Our models have 4 to 6 speeds, depending on the system.
- Anti-drip. The plunger pulls back slightly when you let go, so the nozzle doesn't keep oozing.
- LED light. It lights the joint in dark corners and cupboards.
- Battery system. Choose the gun that runs on your 18V batteries:
- DeWalt-compatible
- Makita-compatible
- Milwaukee-compatible
How to run a neat bead
- Clean and dry the joint. Mask both sides with tape for a crisp line.
- Cut the nozzle at 45°, slightly smaller than the gap.
- Pick a speed that lets you move steadily without stopping.
- Hold the gun at about 45° and push the bead ahead of the nozzle.
- Smooth it with a wet finger or a profiling tool, then pull the tape before the sealant skins.
Tool only or kit?
If you already have compatible 18V batteries, the tool-only version is all you need. If not, a kit with batteries and a charger has everything ready to go.
