I bought this mortar gun in the hope that it would make pointing a gable end quicker, my brickie was sceptical until he used it!! I ended up buying another and saved myself the cost of 2 days labour!! Ensure u use a wet mix n give the gun a wash throught after every fill and it works a treat, even my brickie was impressed!!!

Save your money, I sure wish I had and would have returned it inside the time allowed if I had realised.
This folks, will probably make it into my top ten list of "Greatest Ever Wastes Of Money" As a MORTAR gun it is absolutely useless, a waste of money and time in use. I haven't tried using it for other paste mixtures, such as plaster, but I am in no hurry to.
I have tried a wide variety of mixes of cement, sand, water and plasticizer in it and it simply makes no real difference.
It's not that it is poorly designed and manufactured, which it is. There are considerable burrs and malformations in the plastic components visible from where the moulds are split apart. There is a gap of about 1mm between the edge of the plunger seal and the inside of the barrel.
Why it can't ever work effectively as a MORTAR gun, though, is the laws of physics. Water, plasticizer, sand and cement are loosely bound together and until the mortar goes off, when put under pressure the water in the mix wants to separate from the solids. Put a mortar mix in it and squeeze the trigger a few times and the mortar solids just compact inside the yellow nozzle due to the narrowing restriction of the nozzle and most of the liquid is squeezed out, either through the nozzle or even more of it back past the appraisingly loose seal in the barrel. The irregular grains of building sand just get squeezed together until they are effectively inter-locked.
I wonder if it would be any more effective using soft sand or sand with regular-shaped grains? But that wouldn't be brick mortar then and I am on no hurry to waste more time and effort.
This junk cannot work effectively as a MORTAR gun, by design. Try packing mortar into a 10mm gap between two 4" bricks by hand using a spatula and see how it compacts as you push it further into the gap.
I wonder how many of these that have been bought to be used as a MORTAR gun are returned to Screwfix and other retailers?

This gun simply does not work. I was sceptical about the ability to 'pump' mortar and I have been proved right. Even with a very light mix, very 'wet' and using a plasticiser (washing up liquid) the mortar merely compresses within the gun and will not exit the nozzle. Instead liquid leaks from the gun with undesirable consequences when working above head height. The problem might be related to my technique but I consider myself to be a fairly competent DIYer of many years experience. Unfortunately the gun is destined for the local auction.
