Makita 18V LXT Caulking & Sealant Guns
Makita 18V Lxt Caulking Sealant Guns give you clean, consistent beads without the hand ache, ideal for long runs of sealant, adhesive and mastic on site.
When you're sealing kitchens, bathrooms, cladding, glazing, or fire-stopping all day, a manual gun will ruin your wrist and your finish. Makita's 18V LXT options keep steady pressure, control the flow, and lay repeatable beads so you spend less time tooling and less time cleaning up. Pick the right holder for your cartridges or sausages, match the speed to the product, and get your sealing sorted properly.
What Jobs Are Makita 18V Lxt Caulking Sealant Guns Best At?
- Running long, tidy beads of silicone and sanitary sealant around baths, showers, splashbacks, and worktops without the stop start you get from hand pressure.
- Applying grab adhesive and construction sealants for skirting, architrave, sheet materials, and trims when you need consistent flow and fewer voids behind the fixing.
- Sealing external joints on cladding, window frames, and soffits where a steady bead matters for weatherproofing and you cannot afford thin spots.
- Fire and acoustic sealing around penetrations and service routes where controlled output helps you hit the spec and keep the bead where it needs to be.
Choosing the Right Makita 18V Lxt Caulking Sealant Gun
Match the gun to the sealant format you actually use and the amount you lay in a day, because the wrong holder and you will be fighting it on every cartridge.
1. Cartridge vs Sausage Packs
If you mainly use standard cartridges for silicone and small snag work, stick with a cartridge holder for quick swaps. If you burn through sealant on big runs, a sausage pack setup is cleaner, wastes less, and keeps you moving without constant tube changes.
2. Variable Speed and Flow Control
If you are on thin silicones, you want fine speed control so it does not overrun corners. If you are pushing thicker adhesives, go for a model with enough drive and a usable high speed so you are not stood waiting for the bead to catch up.
3. Battery Choice on the LXT Platform
If you already run Makita LXT, buy body only and share batteries. If you are doing full days of sealing, do not rely on small packs, keep a couple of 5.0Ah batteries in the van so you are not stopping mid bead.
Makita 18V Lxt Caulking Sealant Guns FAQs
What are the features of Makita 18V Lxt Caulking Sealant Guns?
They are built to give consistent pressure and controllable flow, so your bead stays even instead of surging as your grip tires. Most models focus on variable speed control and steady drive for cartridges or sausage packs, which is what stops messy corners and wasted sealant on long runs.
Are Makita 18V Lxt Caulking Sealant Guns available with batteries and charger?
Yes, you will typically see both body only options and kits with batteries and a charger depending on the model. If you are already on Makita LXT, body only is usually the sensible buy because your existing packs will run it fine.
Is there a warranty on Makita 18V Lxt Caulking Sealant Guns?
Yes, Makita tools come with a manufacturer warranty, and you should keep your proof of purchase for any claim. If you are using it commercially, treat it like any site tool, keep it clean, do not leave sealant to cure on the parts, and it will last.
Are Makita 18V Lxt Caulking Sealant Guns suitable for professional tradesmen?
Yes, that is exactly where they earn their keep, especially for fitters and maintenance teams doing repeated sealing and adhesive work. The consistent output and reduced hand strain is the difference between a neat finish at 8am and a messy one after lunch.
Do you offer next day delivery on Makita 18V Lxt Caulking Sealant Guns?
Yes, we offer next day delivery on in stock lines, so you can get the gun on site fast when a job turns into a full day of sealing. Check the product page for live stock and delivery cut off times before you order.
Who Uses Makita 18V Lxt Caulking Sealant Guns?
- Kitchen and bathroom fitters who need repeatable, neat silicone lines all day without wrecking their hands by midweek.
- Joiners and shopfitters using grab adhesive for trims and boards, especially on big installs where a manual gun slows you down.
- Glaziers, cladders, and maintenance teams sealing external joints and frames where consistent pressure gives a better weather seal.
- Dryliners and M and E installers doing fire and acoustic mastic, because controlled application is easier to inspect and less mess to snag later.
How Makita 18V Lxt Caulking Sealant Guns Work for You
They push sealant with a motor instead of your grip, so the bead stays consistent from start to finish. The big win is control and repeatability, especially on long runs.
1. Controlled Plunger Pressure
The tool drives the plunger at a steady rate, which stops the bead going fat and thin as your hand gets tired, and it makes tooling off quicker because the line is more even.
2. Speed Settings for Different Products
Silicone, acrylic, grab adhesive and fire mastic all flow differently, so speed control lets you dial it in to suit the tube and the temperature, rather than fighting blowouts and gaps.
3. Holder Format Affects Changeovers
Cartridge holders are quick for snagging and mixed products, while sausage packs are the choice when you are laying metres of bead and want fewer swaps and less packaging mess.
Accessories That Keep Your Sealing Clean and Moving
A couple of add ons make the difference between tidy output and a sticky mess, especially when you are swapping products on a live job.
1. Spare Cartridge or Sausage Holders
Having a second holder means you can keep one set up for silicone and one for adhesive or fire mastic, so you are not stripping the gun down and contaminating products every time the job changes.
2. Makita 18V LXT Batteries and Charger
If you are sealing all day, a spare 5.0Ah battery and a fast charger stops you getting caught mid run with a dead pack, which is when beads go messy and you waste half a tube redoing it.
3. Nozzles and Finishing Tools
Keep a few nozzle sizes and proper profiling tools in the box so you can match the bead to the joint, because forcing a fat nozzle into a tight corner is how you end up smearing sealant everywhere.
