The Heavy Duty Sealant Caulking Gun is an excellent tool that has made my DIY projects much easier and more efficient. With its 12:1 thrust ratio, this gun provides plenty of power to smoothly apply sealant, silicone, or adhesive with minimal effort. The high thrust ratio ensures that even thicker materials can be dispensed without any struggle, making it a real time-saver when working on larger projects.

I broke two previous guns on my little re-pointing job. Both had been fine for dispensing grout and silicone sealants over the years, but were not up to the tougher cement/mortar that I am currently using. The plastic one just snapped at the trigger and I bent the mechanism of the metal one. Ended up wasting the last quarter of the mortar in the tube. Bought this as a replacement and very pleased indeed. It's built like a tank and works perfectly. I actually finished the whole tube, right to the very bottom. It is excellent value, and I can't see that paying more than double will get you anything better.

Great value, well put together, works very well with some very thick sealant.

What a bargain it's better than my 30 pound brand name and they hole make and feel of the thing is solid and tought teases will lose this before it brakes and a home handy man will have it for life

Much better built than your usual model, and needs less hand pressure. Well worth the money.

Fantastic. Works really well. Sturdy and slow release

After struggling with a B&Q cheap gun this was just a game chager. I have now used it multiple times with both thick and thinner sealants and it preformed very well.Sturdy in construction and a good trigger avtion. I would highly recommend this one
