Caulking gun comparison 2026

The best caulking guns, compared.

Top pick: Everbuild Power Pro applicator gun Best value: Wolfcraft MG 100 – Highest value score at about £8.45, with 130 kg printed, a drip-stop and 4.6 from 8,948 ratings. Updated 22.10.2026.

A caulking gun is a manual tool that pushes silicone, acrylic or adhesive out of a rigid cartridge. In the UK you buy one to seal a bath, a basin or a window, or to lay grab adhesive. The usual sanitary cartridge is about 310 ml. The frame should not twist, a release or drip-stop should unload the piston when you let go, and the cradle should match the tube you bought. Cartridge length, the stop and the push are set out in the [caulking gun buying guide](/hub/fillers-adhesives-and-sprays/caulking-gun/sub/caulking-gun-buying-guide). Foil sausages and air-powered guns are a different tool.

The best caulking guns in detail

Everbuild Power Pro applicator gun

Rank 1

Everbuild Power Pro applicator gun

∼£16

Our view

The Everbuild Power Pro is £15.60, with 4.8 from 3,132 ratings, and it is the heavy steel gun in this set at 790 g. Bullets name a dripless system and a very high thrust ratio, without a number, on a powder-coated skeleton for cartridge adhesives, fillers and sealants. UK reviews describe thick silicone and grab adhesive without the hand fatigue of a cheap gun, and a release that behaves as described. One reviewer loaded a 350 ml Evo-Stik Gripfill that would not fit a cheaper cradle. A trade note says you can angle the cartridge while pressure stays on, and breakage is rare in the sampled UK text. The nozzle pin is fixed in the handle, about 10 cm long, so the cartridge has to come out before you can use the pin. Several buyers hesitate at the price and the weight before they have laid a bead. This listing does not state 400 ml, so the score does not award a 400 ml cradle.

Pros

  • 4.8 from 3,132 ratings, the highest star line here
  • Powder-coated steel at 790 g, with few break reports in the UK sample
  • Dripless release that reviews say behaves as described
  • Thick silicone and grab adhesive without the squeeze of a cheap gun
  • A 350 ml Evo-Stik Gripfill fitted where a cheap gun did not

Cons

  • Nozzle pin is fixed, so the cartridge comes out before you can use it
  • Heavier than the 300 g guns, which buyers notice before the first bead
  • Thrust is described as very high, with no number on the listing
  • Costs more than a bargain skeleton

Best for: Stiff silicone or grab adhesive in a standard or 350 ml cartridge, when you want steel and a dripless release.

Less suitable: A light 310 ml bathroom bead where the MG 100 already stops the ooze for £8.45, or any tube this listing does not show as fitting.

Common questions

What does the Everbuild listing say it fits?

The bullets say standard cartridges of adhesives, fillers and sealants. They do not print 400 ml. A UK review loaded a 350 ml Evo-Stik Gripfill that would not fit a cheaper gun.

Is the thrust ratio numbered?

The bullets say a very high thrust ratio and a dripless system. They do not print a figure such as 12:1. Listed weight is 790 g.

What is the pin in the handle?

A UK review describes a nozzle-unblocking pin about 10 cm long that swings out and is not removable, so the cartridge has to come out to use it.

Wolfcraft MG 200 cartridge gun

Rank 2

Wolfcraft MG 200 cartridge gun

∼£14

Our view

The Wolfcraft MG 200 is the gun most people on this shortlist have actually used: 4.6 from 20,233 amazon.co.uk ratings, at £14.39. It takes a 310 ml cartridge, unloads the piston with an automatic drip-stop, and turns in corners on a rotating handle sleeve. The shell is fibreglass-reinforced plastic at 365 g, and reviewers who abandoned cheap metal cage guns describe a lighter squeeze across a run of windows. One owner dropped it and it did not break. A Geocel decorator's caulk was too long for the cradle, and another review simply says the gun is not quite long enough, so do not buy it for a 400 ml tube. The drip-stop worked at first and then stopped for one reviewer, which means you may still have to pull the rod back. There is no hook to hang it up. The 130 kg figure is printed on the MG 100 listing, not in these MG 200 bullets, so this score does not treat that number as stated here.

Pros

  • 4.6 from 20,233 ratings, the largest sample here
  • Automatic drip-stop when you release the trigger
  • Rotating handle sleeve for corners
  • 365 g, and one reviewer dropped it without a break
  • Less effort than an old gun on a run of windows

Cons

  • Some cartridges, including a Geocel decorator's caulk, are too long
  • Drip-stop failed later for one reviewer
  • No hook for hanging
  • 130 kg is not printed on this amazon.co.uk listing

Best for: A 310 ml silicone or acrylic bead where you want the piston to unload and the sleeve to turn in a corner.

Less suitable: A 400 ml or other extra-long tube, or a job that needs a thrust figure printed on this listing.

Common questions

Which cartridges does the MG 200 list?

The bullets say standard 310 ml cartridges of silicone, acrylic and other fillers. A UK review says a Geocel decorator's caulk tube was about 1 cm too long.

What is the rotating part?

The bullets describe a rotating handle sleeve for bath edges, window reveals and corners. They do not call it a revolving barrel.

Is a thrust ratio printed on this listing?

These bullets do not print a ratio or the 130 kg figure. They do state an automatic drip-stop and a fibreglass-reinforced plastic housing. Listed weight is 365 g.

Wolfcraft MG 100 caulking gun

Rank 3

Wolfcraft MG 100 caulking gun

Our view

The Wolfcraft MG 100 costs £8.45 and holds 4.6 from 8,948 ratings, with 310 ml, an automatic drip-stop and 130 kg pushing pressure printed on the listing. At 299 g it is the lightest gun here, and reviewers say the flow eases when the finger leaves the trigger. The squeeze is described as kinder than a cheap metal cage, cartridges pop in and out, and some owners are still using the same gun years later. It is plastic, so those reviews treat it more carefully than a steel frame, and a few call it a bit flimsy for a full day on site. It is not fully no-drip: one reviewer still draws the rod back after the stop. Extra-long tubes sit outside the 310 ml claim. That mix of a named stop, a named push figure and a price under £9 is why it is the best value on this page, while the MG 200 remains the top pick on sample size and the rotating sleeve.

Pros

  • Automatic drip-stop and 130 kg printed on the listing
  • £8.45 with 4.6 from 8,948 ratings
  • 299 g, lighter on the hand than a cheap metal gun
  • Easy to load and to swap cartridges
  • Still in use years later for some reviewers

Cons

  • One reviewer still pulls the rod back, so it is not fully no-drip
  • Plastic, so it is treated more carefully than a steel gun
  • Called a bit flimsy for trade or a long day
  • Does not take extra-long tubes

Best for: Ordinary 310 ml silicone or acrylic when you want a drip-stop and a stated 130 kg push without paying for the MG 200 sleeve.

Less suitable: A 400 ml trade tube, or a week of stiff grab adhesive where you would rather have the steel Power Pro.

Common questions

Which cartridges does the MG 100 list?

The bullets say standard 310 ml cartridges. A UK review says it does not take the extra-long tubes.

Does the drip-stop work on its own?

The bullets say flow cuts when you release the trigger. One UK review says you still have to draw the pusher back to stop extrusion completely.

What push figure is printed?

The listing states 130 kg of pushing pressure. The item weight is 299 g.

WORKPRO caulking gun 9:1 and 18:1

Rank 4

WORKPRO caulking gun 9:1 and 18:1

∼£20

Our view

The WORKPRO is £19.99 and 4.6 from 3,373 ratings, limited by the title to 290–310 ml, with a separate line that says 295 millilitres. You change the advantage by moving the trigger handle: 18:1 down for adhesive, 9:1 up for acrylic. A red button at the front stops flow; the rear position keeps pressure on. Reviewers mention painted metal with no rust after a few years, a rotating case that helps keep a line, and less stress than a basic gun. Loading is nose-first through a cut-out in the barrel. There is no cutter for nozzle tips. A reviewer without much hand strength still found the trigger too hard, so 18:1 is not a promise for every grip, and the 283 g listing weight is light beside the £19.99 price.

Pros

  • Printed 18:1 and 9:1, switched by moving the trigger handle
  • Red button: front stops flow, rear keeps pressure
  • 4.6 from 3,373 ratings
  • Rotating case, and painted metal with no rust after a few years for one reviewer
  • Nose-first loading through a cut-out in the barrel

Cons

  • No cutter for nozzle tips
  • £19.99 for a manual gun limited to 290–310 ml
  • Still too hard for a reviewer without much hand strength
  • A fair bit of pressure is still required

Best for: A 290–310 ml cartridge when you want a printed 18:1 for adhesive and 9:1 for acrylic on the same gun.

Less suitable: A 400 ml tube, or a weak grip that still struggles after the ratio is switched.

Common questions

How do the 9:1 and 18:1 settings work?

The bullets say you pull the trigger handle down for 18:1 on adhesive and push it up for 9:1 on acrylic.

Which cartridges does it list?

The title says 290-310 ml. The liquid-volume line says 295 millilitres. It is a half-barrel with a rotating cradle, not a 400 ml frame in this listing.

How do you stop the flow?

Press the front of the red button to stop flow. Press toward the rear to keep pressure on the tube. The rod is described as smooth, with a thumb release.

ProDec Advance revolving caulking gun

Rank 5

ProDec Advance revolving caulking gun

∼£10

Our view

The ProDec Advance is a 710 g revolving metal gun at £9.99, with 4.6 from 1,432 ratings, and the bullets claim 310 ml, 400 ml and sizes in between. The barrel rotates for corners and a release clip is meant to stop the flow. Reviewers say it takes longer cartridges as well as smaller ones, feels sturdier than a cheap gun that buckled, and one person kept it through a kitchen, windows and a bathroom. Another used it with Sikaflex on a caravan roof vent. The plunger sticks inside the empty tube when you try to change it, and the disc is too large for some cartridges, including a Wickes mastic. A plunger that is not straight jams at an angle, and pulling it back can be stiff. One gun used a couple of times a week lasted a bit over a year, so regular decorating will wear this frame out.

Pros

  • Claims 310 ml, 400 ml and sizes in between, and reviews support the longer tubes
  • Rotating barrel for corners
  • 4.6 from 1,432 ratings at £9.99
  • Sturdier than a cheap gun that buckled, for reviewers who compared them
  • Release clip to stop the flow

Cons

  • Plunger sticks inside the empty tube when you change it
  • Plunger disc too large for some cartridges, including a Wickes mastic
  • A plunger that is not straight jams at an angle
  • One gun used a couple of times a week lasted a bit over a year

Best for: Mixed 310 ml and longer cartridges, including corners, if you can live with a release clip rather than an automatic stop.

Less suitable: Cartridges whose piston the disc will not enter, or a gun you expect to change tubes quickly all day.

Common questions

Why do reviewers struggle to change the tube?

How do you stop the bead?

The bullets name a release clip to stop flow when required.

Roughneck ROU32230 sealant applicator gun

Rank 6

Roughneck ROU32230 sealant applicator gun

∼£13

Our view

The Roughneck ROU32230 is £12.99, 4.6 from 70 ratings, and all 27 written reviews on the listing are from the United Kingdom, so the star line rests on a small sample. It is a 649 g semi-barrel sized at 265 mm (10.5 inch), with a heavy-duty push rod, a ratchet and a quick-release trigger. One review calls that release about 95 percent drip free. People who replaced a gun whose cam lock had started to slip describe a smooth trigger and a frame that is still sound after regular use. The open ring at the nozzle lets the cartridge come out unless you watch it, and another review says the tube falls out easily. It still drips a bit, and one reviewer found the spring too short for a continuous line of no-nails. Seventy ratings cannot carry the same weight as the Wolfcraft samples.

Pros

  • 649 g semi-barrel at 265 mm (10.5 inch)
  • Quick-release trigger, called about 95 percent drip free in one review
  • Smooth trigger, still sound after regular use for some owners
  • Replaced a gun whose cam lock had started to slip
  • 4.6 from 70 UK-reviewed ratings

Cons

  • Open ring at the nozzle lets the cartridge come out
  • Still drips a bit
  • Spring too short for a continuous line of no-nails, in one review
  • Only 70 ratings, a small sample next to the Wolfcraft guns

Best for: A standard-length 265 mm cartridge when you want a heavier semi-barrel than a 320 g skeleton and you will watch the open collar.

Less suitable: A long no-nails bead, or a tube that slips out of an open nozzle ring.

Common questions

What frame length does Roughneck state?

The title and the included-components line say a semi-barrel gun, 265 mm (10.5 inch), with a ratchet push rod.

Can the cartridge fall out?

A UK review says the collar at the nozzle is an open ring and the cartridge can come out. Another review says the tube can fall out easily. A third likes the cage because tubes stay in.

Will it push no-nails in one line?

The listing does not state a thrust ratio. A UK review says the spring is too short for a continuous bead of no-nails.

Coral 73050 essentials sealant gun

Rank 7

Coral 73050 essentials sealant gun

Our view

The Coral 73050 is £6.56, 4.5 from 681 ratings, a 445 g skeleton marked C3–C4 for 310–400 ml, with a release arm at the back and no stated push figure. A detailed review says it handles both 310 ml and 400 ml, which is a fit note you do not get on every cheap title that mentions both sizes. Owners use it for outdoor door sealant and household silicone and call it sturdy for the money once someone has shown them how to load it. Short reviews still say the quality is ordinary, and some buyers arrived doubtful because other reviews had mentioned poor quality. You have to remember the release arm; nothing here unloads the piston on its own. It is the cheap skeleton to consider when the tube might be 400 ml and you will hit that arm, not when you want the Wolfcraft stop.

Pros

  • A detailed review used both 310 ml and 400 ml
  • Release arm at the back
  • £6.56 with 4.5 from 681 ratings
  • 445 g skeleton described as sturdy for the price
  • Used for outdoor door sealant and household silicone

Cons

  • No stated push figure
  • Quality called ordinary in short reviews
  • One reviewer needed a demonstration before the first load
  • The release arm only works if you press it

Best for: Occasional decorator's caulk or silicone in a 310 ml or 400 ml tube, if you will use the release arm every time you pause.

Less suitable: A silicone bead where you keep forgetting the release, or stiff grab adhesive that wants a heavier frame.

Common questions

Will the Coral 73050 take a 400 ml cartridge?

The size line says C3-C4 310-400 ml, and the bullets say the frame length accommodates cartridges up to 400 ml.

How do you stop the flow?

The bullets say you press the release arm at the back and pull the shank. That is a manual release, not an automatic drip-stop.

What is in the box?

The included-components line describes a wallpaper pasting machine and does not match this gun, so the box contents are n/a from that line. The product is the sealant gun.

ProDec extra strong caulking gun

Rank 8

ProDec extra strong caulking gun

Our view

The ProDec MG11ES extra strong skeleton is £6.82 with 4.4 from 10,534 ratings, the second-largest sample here, at 320 g. The title claims 310 ml and 400 ml. The bullets do not name a flow stop or a thrust figure. Reviewers who rate it well say the frame does not flex and that there is enough leverage for thicker sealant on occasional decorating, across silicone, adhesive and filler. The trigger mechanism occasionally sticks. Hands hurt on a stiff squeeze, and when the product is stiff the trigger feels as if it will bend. Other reviews say it is not strong enough for the extra-strong name. The review count keeps it in the comparison; the missing stop and the stiffness complaints keep it behind the MG 100 on value.

Pros

  • 4.4 from 10,534 ratings at £6.82
  • 320 g, and some reviewers say the frame does not flex
  • Enough leverage for thicker sealant on occasional jobs
  • Used on silicone, adhesive and filler
  • Title claims 310 ml and 400 ml

Cons

  • No flow stop named in the bullets
  • Trigger mechanism occasionally sticks
  • Hands hurt; the squeeze is very stiff
  • Called not strong enough for the extra-strong name

Best for: Occasional decorating with a thin or medium cartridge, when £6.82 and a very large review sample matter more than a drip-stop.

Less suitable: A painful grip, a stiff cartridge, or any bead where you need the gun to unload the piston for you.

Common questions

Does the ProDec extra strong list 400 ml?

The bullets say 310 ml and 400 ml. The style line says an 11 inch (275 mm) extra-strong skeleton. Listed weight is 320 g.

Is a thrust ratio printed?

No. The bullets say a reinforced metal frame for high-viscosity products and a U-shaped bar for a belt or ladder. They do not give a ratio.

What do UK reviews complain about?

A trigger that sticks, a stiff squeeze that hurts the hand, flex when the cartridge is stiff, and a hook that is missing or too shallow. One reviewer says the gun that arrived was not the same ProDec as a 2022 purchase.

Ram heavy duty skeleton caulking gun

Rank 9

Ram heavy duty skeleton caulking gun

Our view

The Ram skeleton is the cheapest row at £5.95, with 4.4 from 185 ratings and a listed weight of 400 g. The title and bullets claim 310 ml and 400 ml, plus a puncture tool and a ladder hook, and they do not name a release or a drip-stop. Positive UK reviews call the metal an upgrade on flimsy guns and say it holds some tubes securely, including tubed cement. The same file says the frame is too short for most refills, and that a 350 ml tube and a 400 ml tube do not fit. The trigger is very stiff; a reviewer with hand pain says people with arthritis should not buy it. One gun broke on first use. The low price does not fix a cradle that rejects the longer tube the title promised.

Pros

  • £5.95, the lowest price in this comparison
  • Metal described as an upgrade on flimsy guns
  • Holds some tubes securely, including tubed cement
  • Puncture tool and ladder hook in the bullets
  • 4.4 from 185 ratings

Cons

  • UK reviews say a 350 ml tube and a 400 ml tube do not fit
  • Frame called too short for most refills
  • Trigger very stiff; a reviewer with hand pain advises against it
  • Broke on first use

Best for: A short 310 ml cartridge of ordinary sealant, if you have checked the tube length against the cradle before you pay £5.95.

Less suitable: A 350 ml or 400 ml tube, a weak or painful grip, or anyone who needs a named drip-stop.

Does the Ram gun take a 400 ml tube?

Does it have a drip-stop?

The bullets list a puncture tool and a ladder hook. They do not name a release plate or an automatic drip-stop.

The listing item weight is 400 g.

G4GADGET heavy duty sealant caulking gun

Rank 10

G4GADGET heavy duty sealant caulking gun

Our view

The G4GADGET is £6.99, 4.3 from 454 ratings, a 470 g skeleton titled for 310 ml, with a release clip and a claimed 360 degree rotating barrel. Short reviews call the action smooth and the gun comfortable for a first-time user, and one person got through cement repairer that had broken a cheaper gun. A handle buckled and broke after about five minutes in another review. 310 ml tubes are a tight fit, and the gun is described as smaller and less sturdy than the heavy-duty wording. One buyer had already seen it cheaper in a shop. A frame that folds on the first tube is a reason to reject the goods, not a loading tip.

Pros

  • Release clip and a claimed rotating barrel
  • Smooth progressive action in short reviews
  • One user finished cement repairer that broke a cheaper gun
  • £6.99 with 4.3 from 454 ratings
  • Comfortable for a first-time user, in the positive notes

Cons

  • Handle buckled and broke after about five minutes
  • Smaller and less sturdy than the heavy-duty description
  • 310 ml tubes are a tight fit
  • Seen cheaper in a shop

Best for: A single 310 ml tube of ordinary sealant, if the frame feels solid in the hand before you start.

Less suitable: Anything stiff enough to buckle a handle in the first five minutes, or a 400 ml tube.

Common questions

Is the rod a ratchet?

The bullets say a smooth round rod, a rotating barrel and a release clip. They do not state a thrust ratio.

One UK review says the handle buckled and broke after about five minutes. Other reviews say it did the job.

Sentoo caulking gun kit

Rank 11

Sentoo caulking gun kit

∼£19

Our view

The Sentoo kit is £18.99, 4.2 from 95 ratings, listed at 900 g, with a claimed rotating barrel, a drip-free claim, a spout cutter, a 5-in-1 finishing tool and a scraper. A review says a 295 ml cartridge fits and warns that very long tubes from B&Q do not. It is praised as a starter set for a small shower or bath, and some reviewers find the gun more controllable than a flimsy skeleton. Pressure stopped after one use because the tightener would not hold. A barrel arrived broken after the return window had passed, another gun broke after about two minutes, and a base started to warp after two tubes. At this price you are paying for the tools around a frame those reviews do not keep. The 5-in-1 extender is also described as very tight.

Pros

  • Starter kit for a small shower or bath, in the positive reviews
  • Removal and smoothing tools that do the DIY job
  • Some reviewers call the gun more controllable than a flimsy skeleton
  • Holds the tube steady

Cons

  • Stopped building pressure after one use because the tightener would not hold
  • Barrel arrived broken, and the return window had passed
  • Broke after about two minutes, and a base warped after two tubes
  • £18.99, and very long B&Q tubes do not fit

Best for: A one-off small shower or bath only if you mainly want the finishing tools and you check the frame before the return window closes.

Less suitable: A second tube of sealant, a long B&Q cartridge, or a gun you expect to keep pressure after the first use.

Common questions

What comes in the Sentoo kit?

The bullets describe the gun, a spout cutter, a needle for dried caulk, a 5-in-1 finishing tool and a stainless scraper. The technical line says caulk gun kit.

Will a long tube fit?

Millilitres are not in the technical table. A UK review says a 295 ml cartridge fits and that very long tubes from B&Q do not.

What broke for reviewers?

UK reviews include a tightener that would not hold after one use, a barrel that arrived broken, a gun that broke within minutes, and a base that warped after two tubes.

Grapelet caulking gun kit

Rank 12

Grapelet caulking gun kit

Our view

The Grapelet kit is £8.99, 4.2 from 60 ratings, and 560 g, sold with a scraper, a smoothing tool and a sealant repair tool rather than as a gun alone. The specification states no millilitre size; a UK review says tubes longer than 230 mm (9 inches) do not fit. First-time DIYers like the tools at a price below buying them separately, and some prefer the smooth rod to a cheap ratchet. A review says the barrel looks as if it should rotate, but it is fixed. Metal bent and warped on first use, a plumber described weak metal and crude plastic, and spare nozzles do not fit the tubes that reviewer already owns. The putty knife is called sharp and poorly finished. The accessories do not make a bent frame into a trade gun.

Pros

  • Smoothing and cleaning tools included, cheaper than buying them separately
  • Smooth rod praised against cheap ratchet guns
  • Balanced gun and a precise trigger, in the positive reviews
  • Spare nozzle caps liked even when the nozzles do not fit
  • £8.99 with 4.2 from 60 ratings

Cons

  • Metal bent and warped on first use
  • Tubes longer than 230 mm (9 inches) do not fit, in a UK review
  • Spare nozzles do not fit the tubes that reviewer owns
  • Putty knife called sharp and poorly finished

Best for: A first bathroom bead on a tube shorter than about 230 mm, if you want the scrapers and you can return a warped frame.

Less suitable: A 310 ml-plus trade tube, or anyone treating the kit price as proof the gun is heavy duty.

Common questions

Is this only a caulking gun?

The listing is a kit. Included components name a caulking gun plus a scraper, a smoothing tool and a sealant repair tool.

What tube length fits?

The technical table does not give millilitres. A UK review says the gun will not take a tube longer than 230 mm (9 inches).

Does the barrel rotate?

A UK review says it looks as if it should rotate, but the barrel is fixed.

How we compared

Twelve amazon.co.uk caulking-gun listings were scored on a 0–100 scale. Amazon evidence is 50 points, from the star line, the review count and repeated first-use bends or loss of pressure in the UK texts. Cartridge, stop and push is 35 points: a cradle whose millilitre claim matches the UK reviews, a stop you can name, a printed kilogram figure or ratio, and a rotating sleeve or barrel the reviews actually use. Value is 15 points, from the shelf price against a stop that works and a review sample you can read. The highest total is the top pick. The highest value-part score that is not the top pick is the best value. This is not a lab test, and a score is not a bead-quality test. Prices are the amazon.co.uk shelf prices on 21 October 2026.

Caulking gun buying guide

Match the cartridge length first, then the stop, then any printed push figure, then the frame weight. A 310 ml drip-stop gun suits a bath or a window. A heavier steel frame suits stiff grab adhesive. Prefer a large UK review count over a high score from a handful of ratings. A drip-stop unloads the piston. You still tool the bead.

What is a caulking gun?

A caulking gun is a manual tool that pushes silicone, acrylic or adhesive out of a rigid cartridge. You use it to seal a bath, a basin or a window, or to lay grab adhesive. The usual sanitary cartridge in the UK is about 310 ml. This comparison is manual guns only. Foil sausages and air-powered guns are a different tool. Quality is the frame not twisting, a release or drip-stop that unloads the piston when you let go, and a cradle that matches the tube length you bought.

Best for

  • A first 310 ml bathroom, basin or window bead, with a drip-stop
  • Stiff silicone or grab adhesive in a cradle the listing and the reviews both accept

Not ideal for

  • A 400 ml trade tube bought on a title that reviewers say is too short
  • A painful grip on a 320 g skeleton that only says heavy duty

Mistakes to avoid

  1. 1

    Trusting both sizes on the title

    A listing that says 310 ml and 400 ml can still be too short. UK reviews of the Ram say a 350 ml tube and a 400 ml tube do not fit. Check the fit notes on that listing.

  2. 2

    Blaming the silicone for a ratchet

    A skeleton keeps pushing until you hit the release plate. A drip-stop is designed to unload the piston when you let go. You still tool the bead either way.

  3. 3

    Buying the kit as proof of a trade gun

    Grapelet and Sentoo include scrapers and profilers. Reviewers like the tools and still report warped frames, bent metal and nozzles that do not fit. The extras do not make the gun stronger.

What to weigh up

Cartridge length

High

A listing that says 310 ml only, as the Wolfcraft MG 100 and MG 200 do, and as the WORKPRO does at 290–310 ml, will not take a 380–400 ml trade tube. Titles that say 310 ml and 400 ml still draw fit complaints. The Ram is the clear example: the title claims both sizes, and UK reviews say a 350 ml tube and a 400 ml tube do not fit. The Coral 73050 is marked C3–C4 for 310–400 ml, and a detailed review used both.

How the gun stops

High

A ratchet skeleton keeps pushing until you hit the release plate. That is the Ram, the Coral release arm, the ProDec Advance release clip, the G4GADGET release clip and the ProDec MG11ES, which names no stop at all. A drip-stop is meant to unload the piston when you release the trigger. Wolfcraft prints that stop on the MG 100 and the MG 200. One MG 100 review still draws the rod back, and one MG 200 review found the stop worked at first and then failed.

Which option suits you?

Three typical situations, each with a recommendation from this comparison.

First bathroom bead

You are sealing a bath, a basin or a window with a standard 310 ml cartridge. The Wolfcraft MG 200 is the top pick at about £14.39: an automatic drip-stop, a rotating handle sleeve, 365 g, and 4.6 from 20,233 ratings. Some tubes are too long for the cradle. You still tool the bead.

Drip-stop under £9

You want a drip-stop and a stated 130 kg push without paying for the MG 200 sleeve. The Wolfcraft MG 100 is the best value at about £8.45, at 299 g, with 4.6 from 8,948 ratings. It is plastic, and one reviewer still draws the rod back. Extra-long tubes sit outside the 310 ml claim.

Stiff adhesive

You are laying grab adhesive or thick silicone and you want a heavier steel frame. The Everbuild Power Pro is about £15.60, at 790 g, with 4.8 from 3,132 ratings and a dripless claim. The thrust line has no number. A 350 ml Evo-Stik Gripfill fitted in a UK review. This listing does not print 400 ml.

Common questions about caulking guns

Which caulking gun is the top pick in 2026?
The top pick is the Wolfcraft MG 200 at about £14.39. It lists a 310 ml cartridge, an automatic drip-stop and a rotating handle sleeve, at 365 g. Across 20,233 amazon.co.uk ratings it sits at 4.6, the largest sample here, with few break reports in the UK texts. A Geocel decorator's caulk was too long for the cradle. The 130 kg figure is printed on the MG 100 listing, not on this one. This is not a lab test.
How much does a caulking gun cost?
These twelve amazon.co.uk listings run from about £5.95 to about £19.99. Entry guns sit around £5.95 to £8.99, including the Wolfcraft MG 100 at about £8.45, which is the best value. Mid listings sit around £9.99 to £15.60. The MG 200 is about £14.39 and the Everbuild Power Pro is about £15.60. The Sentoo kit is about £18.99 and the WORKPRO is about £19.99. A lower price does not win when the cradle or the frame fails in the UK sample.
What should I check before I buy a caulking gun?
Start with the cartridge length. A listing that says 310 ml only will not take a 380–400 ml trade tube, and a title that says both sizes can still be too short. Then check how the gun stops. A ratchet keeps pushing until you hit the release, and a drip-stop is meant to unload the piston when you let go. Read any printed push figure, and do not invent a ratio the listing omits. Heavier steel, about 650–800 g, is the pattern reviewers associate with stiff cartridges.
Does a drip-stop give me a clean joint?
No. A drip-stop, or a dripless claim, is meant to unload the piston when you release the trigger. It does not tool the bead, and it does not guarantee a clean joint. On the MG 100, one UK review still draws the rod back to stop extrusion completely. On the MG 200, one reviewer found the stop worked at first and then failed. You still finish the bead by hand. A release plate on a skeleton only works if you press it.
Will a gun labelled 310 ml and 400 ml take every tube?
Not on the evidence in these listings. The Ram title says 310 ml and 400 ml, and UK reviews say a 350 ml tube and a 400 ml tube do not fit. The Coral 73050 is marked C3–C4 for 310–400 ml, and a detailed review used both sizes. The ProDec Advance claims both sizes, and reviews support the longer tubes, though the plunger disc is too large for some cartridges. Check the fit notes on that listing before you buy the longer tube.
When should I use a heavier gun for grab adhesive?
Stiff silicone and grab adhesive need more advantage than decorator's caulk. The Everbuild Power Pro, at about £15.60 and 790 g, is the heavy steel gun here, with a dripless claim and no numbered thrust ratio. A UK review loaded a 350 ml Evo-Stik Gripfill that a cheaper cradle would not take. The WORKPRO prints 18:1 and 9:1 on a 290–310 ml tube at about £19.99. The adhesive is a separate choice in the grab adhesive comparison.
When should a professional take over?
Call a professional when water is already coming through a shower or a ceiling, when the joint is specified for fire, glazing or structural movement, or when the safety data sheet calls for respiratory protection or a confined space. A production run is a job for an air gun, not one of these manual frames. BS EN ISO 11600 classifies the sealant, not the gun. For the cartridge, follow the HSE isocyanate guidance: ventilate, and wear the gloves the sheet names.

Our verdict

The top pick is the Wolfcraft MG 200 at about £14.39. It is a 310 ml gun with an automatic drip-stop and a rotating handle sleeve, listed at 365 g, and 4.6 from 20,233 amazon.co.uk ratings. Few UK reviews report a break. The 130 kg figure is not printed on this listing, and some cartridges are too long. The best value is the Wolfcraft MG 100 at about £8.45: the next drip-stop gun, with 130 kg printed and 4.6 from 8,948 ratings. A drip-stop unloads the piston. You still tool the bead.
