Makita Caulking & Sealant Guns
Makita caulking gun options for clean, controlled sealant runs, especially when you are sick of fighting stiff tubes and messy beads on snagging.
When you are sealing baths, fitting kitchens, weatherproofing frames, or running fire-rated mastic, a Makita sealant gun keeps the bead steady and the finish tidy. Go 18V if you are doing it all day, and consider bare units if you are already on Makita batteries.
What Are Makita Caulking Guns Used For?
- Running consistent silicone beads around baths, showers, and splashbacks so you are not stopping and starting when the tube gets stiff.
- Sealing window and door frames on refurbs and extensions where you need clean lines and even pressure to avoid dragging and smearing.
- Applying mastic and fire-rated sealants around service penetrations and second-fix details when you need controlled flow and a neat finish for sign-off.
- Weatherproofing exterior joints on cladding, soffits, and trims where a steady bead helps stop pinholes that let water in later.
- Doing repetitive snagging and finishing work in occupied properties where quieter, smoother application means less mess and less wipe-down.
Choosing the Right Makita Caulking Gun
Sorting the right one is simple: match the gun to the tube type and how much sealant you realistically push out in a day.
1. 18V cordless vs manual
If you are doing one bath a week, a manual gun gets you by. If you are sealing daily, go Makita sealant gun 18V so the feed stays smooth when the sealant is cold, thick, or near the end of the tube.
2. Cartridge size and format
Do not guess the holder size. Most site silicone is standard cartridges, but some mastics and adhesives come in larger formats. Pick the gun that matches what you actually buy, otherwise you will be stuck swapping tubes mid-job.
3. Bare unit vs kit
If you are already on Makita LXT, a Makita caulking gun 18V bare makes sense and keeps cost down. If you are starting from scratch, a kit with batteries and charger stops you losing time on day one.
4. Control and clean finish
If you care about a sharp finish, prioritise models with controllable feed so you can slow down for corners and speed up on long runs, instead of flooding joints and wiping half of it off.
Makita Caulking Gun FAQs
Does Makita make a glue gun?
Makita make cordless dispensing tools for sealants and adhesives, which is what most trades mean by a glue gun on site. For hot melt craft-style glue guns, that is a different type of tool and not the same as a Makita caulking gun built for cartridges and mastics.
What are common problems with sealant guns?
The usual headaches are inconsistent bead thickness, sealant continuing to ooze after you stop, blocked nozzles, and the plunger slipping or binding when the tube gets stiff. Most of that comes down to poor control, the wrong holder for the tube format, or trying to push cold, thick sealant without enough steady pressure.
Is a Makita sealant gun 18V worth it over a manual gun?
If you are doing repetitive sealing, yes, because it keeps the feed consistent and saves your hands on thick products. If it is just the odd tube now and then, a decent manual gun is fine and you will not see the payback.
What does bare unit mean on a Makita caulking gun 18V bare?
It means you get the tool only, without battery and charger. It is the sensible buy if you already run Makita LXT batteries across your drills, impacts, and saws.
Will these guns take standard silicone cartridges?
Most Makita mastic guns in this range are set up for standard cartridges, but always check the holder type and capacity before you buy, especially if you use sausage packs or larger adhesive tubes. Getting the wrong format is the quickest way to waste time on site.
Who Are Makita Sealant Guns For on Site?
- Bathroom fitters and kitchen installers who need a consistent bead to get a clean line first time, not after ten minutes of tooling and rework.
- Joiners and window fitters sealing frames and trims, where steady feed stops the bead thinning out at corners and joints.
- Maintenance teams and site snaggers doing repeat rooms all day, because an 18V Makita mastic gun saves your hands and keeps output consistent.
- Fire-stopping and M and E trades applying sealants around penetrations, where controlled flow helps you fill properly without over-gunning and smearing.
How Makita Caulking Guns Work for You
A powered Makita mastic gun pushes the plunger at a controlled rate, so the bead stays consistent and you are not fighting hand pressure all day. The basics below help you pick the right setup.
1. Controlled feed equals a cleaner bead
Instead of squeezing harder as the tube thickens, the gun maintains steady pressure, which is what stops thin spots, blobs, and messy restarts when you lift off and go back in.
2. Tube format matters more than people think
Cartridges, sausages, and larger tubes do not fit the same holders. Getting the right format means quicker reloads and less sealant wasted when you are swapping and trimming nozzles.
3. 18V platform keeps it simple on site
A Makita sealant gun 18V runs off the same batteries as the rest of your LXT kit, so you are not carrying a one-off charger just to get through a snagging list.
Makita Caulking Gun Accessories That Save Time and Mess
The right add-ons stop blocked nozzles, wasted tubes, and walking back to the van mid-bead.
1. Spare nozzles and nozzle cutters
Keep a few nozzles and a proper cutter in the box so you can set the bead size cleanly and swap fast when one blocks, instead of hacking it with a knife and ending up with a ragged finish.
2. Plungers and holders for different tube formats
If you switch between cartridges and sausage packs, the correct holder and plunger setup stops slipping, uneven feed, and wasted sealant when the tube is nearly empty.
3. Makita LXT batteries and a fast charger
If you are running a Makita caulking gun 18V bare, a spare battery is what keeps you working through a full snag without stopping halfway through a run because the pack is dead.
