I think my sealant gun has a faulty spring. As most of the time after squeezing out whatever substance I am using it continues to ooze from the tip. It does it with pink grip, decorators caulk and other stuff.
So rather than persevere with it any longer I will get a new one.
Recommendation please.

You need to hit the "release" lever, there's no spring driving it as such, just the stored elastic energy. OK it's a spring if you like.
There are some designs that don't do that. I've got one I bought when it was on offer at B&Q a few years back. I think it's a Stanley but I can't see a name on it. The part where the tube of stuff goes is like a half a pressed steel tube (slit in half lengthways) rather than the usual two struts, and the front-of-tube end is a U-shape. At the front is a piece of wire on a rivet you can swivel round to poke blockages out of the end of a tube, and the handle end is steel folded into U-shaped sections and in the fixed part of the handle is a hole with "SPOUT CUTTER" stamped into the metal. And it's blue and costs about £7 (when not on offer).
Don't buy the Durgun. Expensive piece of sh1te.
Yep, I'd agree with that. The slight distortion of the plastic sealant container and/or the gun itself. The tap the relese and the ozzing stops or is very much reduced.
Yeah I've got one of those.
In theory - it's great: the idea is that its plunger attaches to the moving base of the sealant tube and allows you to retract the base, so not only can you stop the flow from the nozzle dead in its tracks, you should be even be able to slurp a bit up again if need be.
However in practice about 7 times out of 10 you can't get the plunger firmly attached to the moving base of the tube, so it rarely performs as advertised. I wouldn't buy one again.

Got a Lidl one a few weeks ago and have just started using it. It's an aluminium cylinder type which can be used for bulk material or cartridges. Vastly better than my previous steel frame one.
Surprised that you would consider buying a new one (of anything) without really understanding the problem. A new one could give the same problem unless you have rationalised what the difference needs to be.
I shall continue to hit the release lever to relieve the built up pressure. Never had a problem.

Are you releasing the stop lever after each application
Here's one *not* to buy:
There is a 'push' lever at the end of the plunger part but I've assumed it was to be used to release the plunger for retracting it when a filler/sealant is empty. I now see that from reading previous posts its function is to alleviate the problem I've been experiencing.
I think I might shoot someone tomorrow.

I do that if I'm using a frame gun but with the sort of half-shell gun you don't need to.

What I often find (depending on the sealant type) is that the piston in the cartridge tends to stick, maintaining pressure in the cylinder even when the load on it has been removed (by retracting the activating rod). In these cases changing the gun will not make any difference. There is pressure built up in the cylinder (presumably mainly in a slight expansion of the tube) and the sealant will continue to ooze until the pressure is relieved. This is more likely to happen with a tube that is no longer new.
My finger might slip and then ding my finger nail. Thats agony...you heartless swine!

In that case, manufacturers of sealant guns and sealant gun consumibles should get together. The sealant tubes should have a compressible area on the side of the tube which could be squeezed with the fingers a second before applying trigger pressure with the piston, and then released after the releasing the trigger pressure on the piston. This would release any excess pressure back into the tube. Arthur,
Too complicated. More moving parts means more things to go wrong.
In practice I find tubes (mostly Stixall, acrylic solvent-free glue stuff and sometimes solvent-based gripfill-type) don't ooze in the half-shell gun, and usually do in the frame type guns.
