QWORK® Electric Mortar Grout Gun, All Metal Cement Caulking Gun with 4 Nozzles

For the money, absolutely outstanding. Get the metal one first off. The other review which is by a builder, is one to read. Only thing I can add is that obviously the more mortar in it means you get more material through the nozzle due to the weight. Tilting the hopper, if it isn't full means you can reduce the material being applied, or just use a multispeed drill and partly depress the trigger. Ill probably make my mix a litter drier next time, but first impressions are out of this world.

Brilliant. I am at best oak diyer and this was awesome. Saved time and sanity. Results are really good and easy to clean after use.

I am in the process of pointing an old wall that has been repointed before. Unfortunately the old pointing was only a couple of mm deep, so I have tried a couple of different things to get a good clean and deep enough for a decent fill. I settled for a 5.5mm thick segmented 115mm diameter wheel on a disc cutter. This has given me nice clean grooves about 25mm deep - plenty for a decent fill of clean mortar. OK so a bit too deep perhaps, but I couldn't find a suitable 100mm disc for my small grinder. having said that, the brickwork is uneven and I have resorted to a 1.5mm disc in places where the pricks are really tight together, along with a 'drill like' bit for the vertical joints as the discs are just way too big. Having done a bit of this reponting with a standard pointing trowel, I found getting the mortar in to the back a bit tricky, not surprising given the depth of the groove. I then switched to a 10mm tuck trowel/pointing tool which worked far better even if a bit to wide. However always eager to save a bit of time (so I can do other things) I ordered this item. On opening the box, there were only 4 nozzles inside, the white threaded one was missing. Never mind. I then took the narrowest nozzle to the brickwork. There was nowhere even the narrowest nozzle would fit, being ½" wide (12.5mm) so absolutely no chance of getting the mortar deep enough without making a mess. All the other nozzles were as big or bigger, so this item isn't really suitable for pointing fairly standard brickwork unless you have really big gaps between the bricks or blocks. So now I'm off to pick up a 6mm tuck pointing trowel as that should work even better than the 10mm one for getting the mortar to the back of the groove. Happy pointing.

Having used a few pointing guns in the past, for big straight runs this thing is 'top gun' loads faster than the silicone gun types but with one draw back....it doesn't do well in the tighter spaces, just because of the hopper on top but apart from that it's brilliant

Good bit of kit but you’ve got to have your mix right or it will drive you nuts !

. As a professional builder in the UK, I can confidently say this is the best product on the market for pointing work. I've tried using mortar guns similar to large silicone guns, but they are notoriously unreliable. They struggle with water compression and can become a nightmare if sand or cement clumps inside. After years of using these silicone gun-type pointing tools, I finally found this superior alternative and felt compelled to share my experience with fellow tradespeople. This tool utilizes an Archimedes screw mechanism, which means it doesn't compress the mortar mix but simply pushes it out from the trough. This design eliminates many of the issues common with other tools. For traditional pointing, I use NHL 3.5 Lime and sand with a mix ratio of 1 part Lime to 2.5 or 3 parts sand. For the best results, it's advisable to hire a cement mixer, but exercise caution as these machines can be extremely dangerous. Always keep hands and arms clear of the fins when the motor is running and seek training from the rental provider if needed. Start by mixing the dry ingredients for at least 10 minutes, then gradually add water until you achieve the desired consistency. Lime acts as a plasticizer, so when you see the mix balling and clumping together, it's about right for traditional pointing. For use with this pointing tool, you'll need to add a bit more water, but be mindful that excess water can lead to shrinkage in the mortar mix. Lime sets in two stages: initially with water and then with air. Hydraulic Lime is preferable as it sets harder than hydrated Lime. Always wear a mask and goggles when mixing this type of mortar. After mixing for an additional 10 minutes, you're ready to go. Use a half-moon pointing tool to create a fully weathered edge in the joints. The quality, value, and versatility of this product are exceptional, saving you significant time and ensuring the mortar is fully pumped into the back of the cut or rake-out. This tool is excellent for both professional tradespeople and DIY enthusiasts. Remember to use a wall chaser or angle grinder to cut back the old mortar by at least 15mm. Highly recommended!

You need to make your mortar mix quite sloppy for this to work and it does sometimes clog but it does work for me. Put the mortar in the gaps between slabs, wait 2/3 hours for it to set a bit then finish off. Results speak for themselves.

Due to the quality of out sand in the uk, iI struggled. It would only work for a short period and then get blocked. Unable to use for patio grouting.
