Roughneck ROU32150 Ultimate Mortar Gun - Heavy Duty Applicator for Mortar, Grout, Adhesives, Sealants - Back

Great product - I had fitted a double glazed back door which had lots of gaps between the bricks and the frame (some quite narrow gaps but deep). I’d read a few of the reviews so I was a bit cautious if this was going to be a good tool, particularly some comments about water being squeezed out of mortar etc. I decided I would try just half filling the tube each time and I have to say this worked brilliantly. Yes a couple of times it did block up but this happened when I had filled the tube about 3/4 full rather than 1/2 full - very simple to rectify, take the nozzle end off and squeeze the trigger to eject the blockage, refill half way and go again!I used this for doing vertical sides and horizontal across the door frame top - this was repeated on both sides of the door. The cement was ‘injected’ deep into the gaps, far deeper than I could have managed with a finger or trowl.Finally, I had some cement left over so I used it to fill a few gaps in my patio mortar - it did this really well.So - you’ll see some negative reviews on here, and granted I’m not a professional tradesman, but more of a hap hazard / semi useful DIYer - however this roughneck product felt very well made and did exactly what I needed it for, brilliantly. Don’t be greedy, if it squeezes out too much water and then blocks you’ve probably overfilled it for the mix your using so just empty it and out a bit less in next time.

Great device to use. There are some great you tube videos on this. Like other reviews I used their advice and went for the 4-1 mix (builders sand and Portland cement) with some plasticiser and yes make sure the mix is kind of sloppy! I made a funnel out of a plastic comfort bottle to get the mix into the device. Comes out very easily without any blockages and fills the gaps perfectly without mess. Only towards the end the mix compresses the water out and then the mix goes solid, so unscrew the end, take out the solid chunk with your fingers and recycle back to the mix and then refill. Easy! Good advice to have a bucket of water at hand so you can dip the end cap in to get rid of the residue as sometimes the cap can be hard to screw on due to the grit in the thread. The whole suit is really robust and you get spare ends too. So overall really pleased with this and saved me a lot of mess for a little cost.

Bought this to help speed up repointing a couple of walls and chimney breasts. Tbh, once you get your mix right for the gun (but wetter than normal), it goes on a treat. And it's kind of worth the extra hassle of having something else to disassemble and clean. You'll still need small hand tools for places inaccessible to the gun. It's nice knowing that the mortar is fully to the base of the voids.

Used a different brand before which broke and wasn’t very good. I ended up watching a product review on YouTube where the guy used it with lime to do his brick slips. Thought I’d try this brand as it’s easy returns with Amazon but it actually worked really well. Solid mechanical parts and seem really well built. Do the wall in my new bathroom today using this.

Waste of money,used them before and thought I’d spend a bit more and get a decent one,worked ok for about 15 minutes then just packed up,kept gripping the handle and it would not push forward,cost me money in the end as I had a lot of pointing to do and let me down big time,25 year guarantee more like 25 minutes if your lucky,will be sending back

Good idea and did save some work with a trowel, but ultimately did not last very long. After every use, I had to take it apart as the plunger did not pull back. Also, about 1/3 of the product within the tube, ended up behind the Plunger and had to be scraped out after every go. I had quite a bit to do, filling in 20-25mm Gaps in Stone Cladding and probably lasted till about halfway through the job, before I gave up and reverted to the trowel.

Well built. Better than my previous one. Great selection of different ends.If unsure go to the You Tube video. Nearly completed both the side and front of the house. Nice creamy mix, works a treat. Highly recommended.

Get the mortar mix right and it works brilliantly. Aim for a consistency like toothpaste and it will easily squeeze out of the mortar nozzle and remain in place on brickwork. Using a plasticiser is essential. Before starting the job make a small sample mix to experiment with the consistency and to see how the gun works. YouTube has some very useful tips.
