Cordless caulking guns for clean, even joints
Sealing a shower, fitting skirting boards, bonding panels or finishing window frames: squeezing a manual caulking gun for hours is tiring and rarely gives a perfectly even bead. A cordless caulking gun (also called an electric sealant gun or battery kit gun) does the pushing for you. The result is a steady flow of sealant or adhesive, cleaner joints and far less strain on your hand and wrist.
Two battery-powered caulking guns
- 18V Cordless Caulking Gun: the choice for demanding jobs and frequent use. High, continuous discharge pressure (2000 Nm according to the specifications), adjustable extrusion speed from 0.8 to 9.3 mm/s, anti-drip function and a choice of simple or fast extrusion. Runs on the 18V Maxxpack battery.
- 6V Maxxpush Caulking Gun with LED Work Light: light and easy, weighing just 0.9 kg. Powered by 4 standard AA batteries, with an integrated LED work light and an anti-leak function with automatic pressure release. Ideal for occasional sealing and small home repairs.
Both caulking guns take standard 290–310 ml cartridges and are suitable for all common adhesives and sealants, so there is no need for special tubes.
Applications
- Sealing showers, baths, sinks and kitchen worktops with silicone
- Filling joints around window frames and door frames
- Fitting skirting boards, trims and wall panels with mounting adhesive
- Sealing seams after tiling or installing flooring
- General repairs and renovation work in and around the house

Features that make the difference
- Anti-drip / anti-leak: pressure is released as soon as you let go of the trigger, so no sealant oozes onto your floor.
- Adjustable speed (18V): slow for fine detail, fast for long joints.
- High pressure (18V): handles thick adhesives and sealants without effort.
- LED work light (6V): see your bead clearly under sinks, in cabinets or in dark corners.
Benefits of a cordless caulking gun
Without a cable you can work on a ladder, in a bathroom or outside without searching for a socket, and nothing trails across a freshly sealed surface. The motor delivers consistent pressure, which is the secret to an even joint, and you avoid the hand fatigue of a manual gun. With the 18V model you also benefit from the Maxxpack system: one battery for more than 50 Batavia tools, such as drills, sanders and heat guns. Discover the full range in the 18V Maxxpack collection.

Frequently asked questions about cordless caulking guns
Which cartridge sizes fit Batavia caulking guns?
Both the 18V Cordless Caulking Gun and the 6V Maxxpush take standard 290–310 ml cartridges and work with all common adhesives and sealants.
What is the difference between the 6V Maxxpush and the 18V Cordless Caulking Gun?
The 6V Maxxpush is very light (0.9 kg), runs on 4 AA batteries and has an LED work light, ideal for occasional jobs. The 18V model offers higher pressure, adjustable speed from 0.8 to 9.3 mm/s and two extrusion modes, and runs on the Maxxpack 18V battery.
How does the anti-drip function work?
When you release the trigger, the gun automatically releases the pressure on the cartridge. This stops sealant from continuing to flow, keeping your work area clean and your joints neat.
Can I use thick adhesives with a cordless caulking gun?
Yes. The 18V Cordless Caulking Gun delivers continuous high discharge pressure, so it handles viscous mounting adhesives and sealants with ease. Use a lower speed setting for better control.
Does the 18V caulking gun use the same battery as other Batavia tools?
Yes. It is part of the Maxxpack 18V platform, so the battery fits more than 50 Batavia tools. It is available as a tool only or as a set with battery and charger. The 6V Maxxpush runs on AA batteries instead.
