Mortar Pointing Grouting Gun Mortar Sprayer Applicator Stainless Steel Cement Caulking Gun Cement Caulking Pump with 5 Nozzle

Worked as expected for filling honeycomb voids with repair grout. Easy to use and not overly expensive. You get a few different adapters and replacement parts.

I never thought it was going to work , I morted in 2 commercial steel doors. It was awesome, I almost bought a $900 hand pump . This worked just as well, crazy good. For 35 bucks .

For this thing to work so the grout comes out of the tube, the mixture needs to be very watery. This defeats the whole purpose of this product. If you do use a proper mixture, you can expect the mix to harden in the tube and then you have a real mess on your hands. Avoid this product.

As other reviewers have noted, I had to lean (water down) the mortar mix, until it was near soup, to get it to flow through any nozzle consistently. Came with zero directions or tips to improve a weak products' performance. Lots of nozzle choices, but none produced any consistent application results Tilting it at an angle is crucial, as it lost suction regularly if I didn't continue to dig the nose deeper into the mortar soup mix. That, then, creates air pockets, of which blew the mortar out stronger than I wanted. Lots of inconsistent beads of mortar, rather than an consistent ribbon of it. Cleaning it should have been easy. The nozzle became frozen on the units' body, and I still can't get it off. Lots of "partial" full canisters, due to the above, causing just too many trips to refill it again. The handle just doesn't create enough power to force normal consistency mortar through it. This is not commercial/industrial strength; perhaps better suited to bug spray your tomato plants. Well marketed, but fell short for me of being a tool I really need for a lot of mortar work. Looks good, but appears to be a cheap knock-off, more of a toy than a tool. Can't recommend this other than to recommend you not buy it.

Keep lubricated. works great for small jobs. Takes too long to reload. I had 1/2" space between bricks to fill with spec mix (type S). Worked great but had to reload too many times. Used vaseline as a lub for the tube and plunger.

I really didn't expect much from this no name brand tool but it actually worked great for my needs. I needed to fill some concrete blocks in a wall to make reinforce them. I drilled a 1 inch hole in the top and used this to inject the cement into the block. I used non shrink grout which is very liquidy and this tool worked great. I have only used it once so I can't speak for it's longevity but for the price it's still worth it even if it doesn't last forever.

you have to have the mortar very thin to get it to come out. Im making it work. and will probity through it away when I'm done. I would not buy it again.

The perfect tool and there is nothing quite else like it available.
