Best mastic gun for ordinary 310 ml silicone

Updated: 2026-10-23

You want one manual gun for a normal 310 ml silicone cartridge, and the star ratings pull in different directions. The Everbuild Power Pro sits at 4.8 from 3,132 ratings. The Wolfcraft MG 200 sits at 4.6 from 20,233. On this shortlist the best mastic gun for ordinary silicone is the MG 200, because it states a drip-stop and a rotating sleeve, and because that review count is the largest here. Shelf prices for all twelve are on the [caulking gun comparison](/hub/fillers-adhesives-and-sprays/caulking-gun). These are recorded shelf prices from 21 October 2026, not a lab score.

Our top picks

On this page

Best for a standard 310 ml tube

The top pick is the Wolfcraft MG 200 at about £14.39. Wolfcraft's page states a 310 ml cartridge, a drip-stop, a rotating grip sleeve and a fibreglass-reinforced plastic body at 0.366 kg. The listing shows 4.6 from 20,233 ratings. The drip-stop unloads the piston when you let go. The sleeve lets the barrel turn at a corner without you twisting your wrist. Skip it when the tube is longer than a standard 310 ml cartridge. Reviewers report a decorator's tube that was too long. Skip it as well when grab adhesive has already bent a light gun and you want the mass of a steel frame. The 130 kg figure is printed on the MG 100 listing, not in these MG 200 bullets.

When the heavier steel gun is the one

Buy the Everbuild Power Pro, at about £15.60 with 4.8 from 3,132 ratings, when the cartridge is stiff or longer than a standard 310 ml tube. Sika's UK page rates the Power Pro for 310 ml and 400 ml, at about 0.8 kg. The amazon.co.uk bullets say dripless and a very high thrust ratio. They do not print 400 ml, and they do not print a number for that ratio. An Everbuild reviewer moved to this gun after a 350 ml Evo-Stik Gripfill tube would not fit a cheaper frame. If the tube is ordinary silicone and the mess is ooze, the MG 200 still matches the job more closely.

The cheaper drip-stop and the dual-ratio gun

The best value is the Wolfcraft MG 100 at about £8.45, with 4.6 from 8,948 ratings. It states a drip-stop, a 310 ml cartridge and 130 kg of pushing pressure, without the rotating sleeve. Buy it when the joints are mostly straight and £14.39 is more than this job needs. The WORKPRO, at about £19.99 with 4.6 from 3,373 ratings, prints 9:1 and 18:1 for 290–310 ml, with a smooth rod and a red button. It belongs here when your grip is the constraint. It does not belong here for a 400 ml tube. The Ram, the Coral and the ProDec MG11ES stay available for thin decorator's caulk if you will hit the release every time.

What other best pages are doing

Other UK round-ups print algorithmic scores you cannot audit. Use the listing facts above. A Screwfix community thread from 2018 recommends an Everbuild Power Pro and says it takes cartridges up to 400 ml. That is an anecdote, not a fresh amazon.co.uk price. The MG 200 is the top pick for standard 310 ml silicone, and the MG 100 is the best value when you do not need the sleeve. This page will not call any model the best gun in the UK or invent a ratio for the Everbuild.

Common questions

Which one gun suits a normal 310 ml silicone cartridge?
The Wolfcraft MG 200 at about £14.39. It states a drip-stop, a rotating sleeve and a 310 ml cartridge, and the listing shows 4.6 from 20,233 ratings. Choose it for a standard sanitary or acrylic tube when you want the piston to unload as you let go. A longer trade tube, or grab adhesive that has already bent a light frame, is where this pick stops.
Who should skip the MG 200?
Skip it for a confirmed 380–400 ml cartridge, and when a decorator's tube has already proved too long. Skip it if you want heavy steel for grab adhesive after a lighter frame twisted. Sika UK puts 310 ml and 400 ml on the Everbuild Power Pro, at about 0.8 kg. The Amazon bullets do not repeat the 400 ml line, so check the tube against both.
Why is the highest star rating not automatically the pick?
The Everbuild's 4.8 from 3,132 ratings is a higher average than the MG 200's 4.6 from 20,233. Both can stand because the guns suit different cartridges. Stars do not publish a thrust ratio. For standard 310 ml silicone, the larger review count plus a stated drip-stop and sleeve is the stronger reason. The higher average fits a stiff or longer tube.
When is the Everbuild the better buy?
When the cartridge is stiff, when a 350 ml Gripfill-style tube has already refused a cheap cradle, or when you want the heavier gun Sika rates for 310 ml and 400 ml. The shelf price is about £15.60, with an unnumbered very high ratio. For ordinary bath silicone where the complaint is ooze, the MG 200 still matches that job more closely.
Is the MG 100 enough if you do not need the rotating sleeve?
Yes, for straight runs and a 310 ml tube. At about £8.45, with 4.6 from 8,948 ratings, it states the same drip-stop and prints 130 kg of push, without the sleeve. That is the best value here. It is the weaker choice at bath corners, where you would miss the rotating grip, and the wrong cradle for a 400 ml tube.
Does best include the WORKPRO?
It includes the WORKPRO as the gun that prints 9:1 and 18:1, at about £19.99, for 290–310 ml only. Buy it when you want that number and a smooth rod with a red button. The MG 200 costs less and has the larger review count for a drip-stop and a sleeve, so it stays the default silicone pick. A 400 ml tube rules the WORKPRO out.
