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

Wish I’d bought this ages ago. Bloody brilliant for all sorts of gap filling and grout application. Easy to set up, wash out & use

I'm a complete novice, an office worker with soft hands and minimal DIY skills. This gun enabled me to repoint one side of my house. It was so much easier and quicker than learning the correct pointing technique that builders or tradesmen use. It took me a while to get the hang of it, the key is in the mix for the mortar. A few videos on YouTube demonstrate how to mix the mortar correctly for this gun. The mix looks really sloppy but stayed in the crevices and with the gun you can see the mortar filling each gap. I used a ready mixed mortar and added a plasticiser. After a few mixes I learnt how to get the best mix possible for the gun and it was easy to use. The job is quite messy and I needed to clean the bricks afterwards but I probably would have made more mess using a trowel or a tuck pointer. I found it useful to only mix small amounts at a time in a medium sized bucket. Then I would clean the gun with a hose after each bucket.

Works well once you get the mix and work-flow sorted

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.

Item delivered in unsealed original product display box, with just the usual delivery sticker slapped on , I suspect that over time this practice will cause parts to be lost in transit, this has been noted by another buyer in a previous review. I so wanted this tool to work as advertised and because of that I ignored the bad points from previous reviews...bad mistake....this mortar gun clogged up pushing only the water content out of the nozzle leaving a hard useless lump of product in the tube and became useless after delivering only 15cm of product. (grouting/cement made up from a powder form correctly as per the instructions) Ready mixed grouting was a little better but not much even when using the larger nozzles. A great pity as the item is well made and sturdy but what use is that when a good overall result is just not possible. I suspect that most of the guns of a similar nature are the same, maybe that's why you cannot find one with good multiple feedback reports. Unless you enjoy wasting your time cleaning and trying to get this to work ,personally I would say don't bother.

good item delivered quickly <(.!.)>

Box had been opened before being delivered to me and foil pack adapter missing. Gun it self seems well made, but see how it performs.

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.
