Versatile lithium-ion battery caulking guns engineered for high-viscosity adhesives, silicone sealant, and gap filling. Features automatic piston retraction, variable speed control, and ergonomic low-fatigue design.
You’re not alone. If you’ve been sourcing cordless caulking guns for your market, you’ve likely run into these frustrating customer complaints:
Messy Overtravel & Drips: Low-end plungers fail to auto-retract when the trigger is released, letting high-viscosity sealant keep oozing out and ruining clean job sites.
Uneven Flow & Motor Stalls: Weak gears strain or bog down when pushing thick adhesives, cold polyurethane, or heavy construction materials, resulting in lumpy beads.
Battery Drain & Mechanical Jamming: Pushing thick cartridges rapidly drains cheap battery packs, triggers motor overload protection, or strips the drive rack mid-tube.
Heavy & Awkward Handling: Bulky, front-heavy frames that tire out wrists during full-day sealing jobs, paired with rigid carriage holders that make loading messy.
The real challenge? Finding a cordless caulking gun that delivers smooth, drip-free beads every time — with effortless speed control and zero messy cleanup.
Explore our heavy-duty range of cordless caulking guns, engineered for smooth, continuous dispensing of high-viscosity sealants, silicones, and structural adhesives. Driven by powerful motor systems with high push force and anti-drip control, our series replaces tiring manual caulking with consistent bead flow, rapid speed, and professional job site precision.
Powered by a robust motor and heavy-duty gear drive mechanism that generates impressive push force (up to 4,500 N – 6,000 N / 1,000+ lbs). Easily handles tough, high-viscosity construction adhesives, polyurethane, structural silicones, and cold-weather sealants without stalling or hand strain.
Features a multi-stage electronic speed dial paired with a variable speed trigger to precisely adjust sealant flow rates. Allows operators to easily maintain uniform bead width, speed through long straight seams, or slow down for delicate corner and detail work.
Built with an intelligent auto-reverse feature that automatically retracts the plunger rod a fraction of a millimeter as soon as the trigger is released. This instantly relieves internal pressure on the tube, preventing messy adhesive run-off, drips, and material waste on finished surfaces.
Designed with quick-interchangeable holders to accommodate standard 300ml/10oz cartridges as well as 600ml sausage foil packs for industrial applications. Powered by a flexible 21V Makita-style pin platform, ensuring seamless battery sharing across your entire tool lineup.
Will your users prefer light indoor agility — or non-stop job site power?
Will your users apply light room sealants — or thick industrial adhesives?
Will your users apply standard cartridges — or high-volume sausage packs?
Will your users need quick sealing jobs — or full-day, swap-and-go work?
Will your users need basic glue pushing — or drip-free precision sealing?

Let’s talk — and get you the performance your customers expect.
Standard 10 oz / 300ml Cartridges: Fits 95% of standard household caulk tubes, silicone, and acrylic sealant bought at hardware stores.
Sausage Packs (20 oz / 600ml): Designed for commercial sausage foil packs (if using a conversion barrel kit).
High-Pusher Force (up to 6,500 N / 1,500 lbs): Easily pushes both light silicone caulk and super-thick, heavy-duty construction adhesives (like Liquid Nails or polyurethane) even in cold weather.
Zero mess! The moment you release the trigger, the plunger rod automatically pulls back a few millimeters to relieve pressure inside the tube. This stops caulk from oozing out onto your floor or countertop.
It controls the flow speed of the sealant:
Low Speed (1–2): For slow, precise, thin beads along kitchen sinks, bathroom tiles, and glass windows.
High Speed (5–6): For fast, thick lines when laying subfloors, driving long adhesive beads, or filling deep exterior gaps.
10x Faster & Smoother: Delivers a continuous, perfectly even bead without jagged stop-and-start bumps.
Zero Hand Pain: Saves your hands and wrists from cramping when squeezing dozens of heavy glue tubes on big renovation projects.
Caulking uses very low battery power compared to heavy tools:
A single 2.0Ah battery can dispense over 100 to 150 standard caulk tubes on one charge! You can easily finish a full house project without stopping.
Yes!
Spout Cutter: Snips the tip off new caulk nozzles cleanly at your desired angle.
Puncture Wire: Flips out to break the inner foil seal inside the tube nozzle instantly.
The heavy-duty motor and auto-overload protection handle stiff material easily. However, to get the smoothest line in cold weather, store your glue tubes indoors at room temperature before use.
Press the quick-release rod button and pull the plunger rod all the way back.
Drop in your new caulk cartridge.
Push the rod forward until it touches the tube base—you're ready to shoot!
Yes, 100%! The complete kit includes:
1× Cordless Caulking Gun Host
Rechargeable Lithium-Ion Battery & Fast Charger
1× Heavy-Duty Metal Cartridge Holder Frame
1× User Manual & Storage Bag/Case
(Charge the battery, drop in any caulk tube, snip the tip, and pull the trigger for smooth, effortless beads!)
