Mortar Grout Gun HBCHEN Large Size Stainless Steel Portable Pointing Grouting Caulking Sprayer with 9 Nozzles, High Temperature Resistant

Setup: Attached to Milwaukee M12 drill and used it to apply type S mortar with 3/8" joints on reclaimed brick. If an M12 can power it than any other quality cordless drill should be adequate.Results: Would have taken 2 guys 3 days to pipe in with bags, this beast allowed 1 guy to do it in 2 days flat.Notes: mix should be soupy and you may snag on larger pieces from time to time but only once did it bind up and need the stone removed. Occasionally you may need to remove tip to clean it out but if you flush a hoppers worth of mortar through after sitting during strike and tooling this seems to reduce blockage to rarely.The location of the handle is cumbersome and personally should be on side rather than bottom.Easy to clean

I was pleased with its performance and its construction, however, the plastic tips do not last long because grouting stone rubs them down rather quickly and then the plastic burrs fold in and block flow. I’m hoping that there are metal tips that can be purchased. Also, if you are working alone like I was you may have to create something to hold the hopper while refilling to keep it from falling over.

I was skeptical before I bought this it looked awkward to hold and and with the weight of the mortar heavy . I used it to grout a 24 x44 detached garage which I brick ( 1 5/8" deep) veered the whole building.Which I did by myself in about a week and a half it worked flawlessly, I highly would recommend it Stan.

Cement has to a little more soupy, also if you are working on angle just does not work

I have never done grout before and i had to grout some brick so I ordered this. It attached to the drill no problem. I would recommend this to anyone! It was amazing and a true life saver. Do not hesitate to buy this you will not regret it!

Well I haven't used it yet. I just opened the box and noticed that if I were to attempt to use it straight out of the box, it would be a hot mess. The area where the hopper meets the gun has a large gap as seen in the picture. So what will prevent mortar coming out that hole instead of just the intended tip of the gun? I'll be able to put some silicone in it, but I don't feel I should have to do that being as though it's brand new. I didn't choose the least expensive option either. Had I known that I was going to get a pathetic welding attempt on pieces of scrap metal that were apparently not measured, I would have just gotten the $20 gun. Not a good example of getting what you pay for in my opinion I hope that it works. Judging by my first impression I won't be surprised if it fails.

Very heavy once loaded, piping bag easier to use for women

A much better way to install mortar between stone veneer than using a grout bag. Tool is well made, easy to use and easy to clean. Quite a value for the low cost. Only recommendation is to set the clutch to a medium setting on your drill in case the mortar temporarily jams. This will prevent the tool from possibility getting torqued out of position.
