Electric Mortar Grout Gun Portable Pointing Grouting Caulking Sprayer with 9 Nozzles (Without Electric Drill)

Works great with premix mortar. I cut the plastic tip as big as possible then cut a plastic mortar bag down and zip tied it behind the plastic tip. Definitely changed the way I grout after 30 years of doing it old school. For the cost I could buy one of these for each job and it would still save me a LOT of money and time. Definitely recommend.

I wanted to like this... I really did. I had some use of it that seemed incredible, but it was just much too inconsistent to use. Much more often than not this tool didn't work. The tips are made of plastic and strip very easily after use. You have to make mortar extremely wet to even flow through this gun. I'm not joking, but I'd say over twice, close to three times the water needs to be added where the mortar will flow out of bucket to dump into the hopper. With grout this wet, it's hard to stay in the joints and is extremely messy. If it's just a little too thick, it will clog the tip and you have to take it off. Apart from that, occasionally the drill will get stuck (due to some sand in the grout) and cause the whole hopper to want to twist with the drill. When this happens, it will most likely fling the hopper with all the wet grout everywhere despite holding the handle on the hopper. When it was working, it was very nice, but the amount of mess it makes and inconsistency with the flow of the tip makes this not worth considering. I'd say I'd only have this working about 20% of the time or less. I tried hard to use it but with how wet you have to make the grout, I imagine a grout bag would be much easier and cleaner to use than this.I just flung grout all over my bricks and floor three times trying to give this a last chance. It's pretty disappointing but I just threw this away since the tips are all stripped and it's making more of a mess than it's worth.

It works but I recommend mixing mortar just a little thick and really push the nozzle in close

My husband used this for the mortor around the base of our home. The job was very large but not enough to justify purchasing a pricey (one time use) mortor gun since he stated... "I will NEVER do that again!" The job went faster for him and less physically muscle intensive than using a mortor bag!It should be noted that he is not a Mason and this was his first (successful) experience working with mortor. In addition he takes excellent care of all of his tools, equipment, and keeps his construction site clean. This tool is properly stored and still in excellent working condition.

The hopper on this item is plastic while the gun is metal. Since the hopper is plastic it cannot be arc welded to the gun. Therefor the plastic of the hopper extends around and below the gun (on either side of the handle retaining nut) to help secure it. The plastic is also glued to the gun providing additional retention. The problem with the item was that at receipt the plastic was already completely cracked underneath the gun on one side of the handle reatining nut. So I had no confidence the hopper would be able to stand up to the rigerous environment it was to be used in. So I sent it back and pruchased a similar unit with a metal hopper which is arc welded to the gun. A little more money but should be more than worth it in the long run.

If you are planning to use this for mortar, then don't get it, unless you are planning to use super-soupy mortar. By the time we had put enough water in the mix in order for it to push it out--and even then with only the largest spout--I had zero confidence that the mortar was even close to code applications. We were using M-type mortar and a heavy-duty corded power drill, and we tried multiple speeds and approaches.

great for a diy. could not have done it with out it.make sand is free of any large sand grains or it will clog. great value for repointing a brick wall

Metal feed would be better but this does work rather well. To feed mortar on rocks and bricks. Even when you have a deep repair that you need to squeeze the stuff down in there. As long as it's like peanut butter then you can make that happen.
