Large Size Auger Mortar Grout Gun With 9 Nozzle Without Electric Drill | A Mortar Caulking Gun that is Faster than A Grout Bag,Mortar Tools with Grout Pump。

This thing worked as expected and saved me so much time repointing my foundation!

I was a bit Leary of this item, seemed too easy but it work very well. You need to get your mix just right and it will take a bit of tries but once we had it down it worked very well. We were using it to fill large gaps, ie; river rock so I am not sure yet how it will do with tight gaps.

First off, I am not a mason, but enjoy DIY projects. We re-did the siding on our house and decided to add a stone veneer for a section. A grout bag didn't work for me, so I thought I would give this grout gun a chance. It is a solid unit, but needs some modifications to be practical for one person to use. 4 stars because I had to modify it. 5 stars if they could solve the design issues. Here are some things that I noticed: Design issues: - The provided tips don't offer the durability and range of a grout bag. (Tip modification described below improved this!) - There is no good way to set it down with a filled hopper without it tipping over. (Handle/Stand modification described below improved stability) Using the grout gun: - The size of sand used in the grout mixture plays a huge part in how smoothly this gun operates. I used Quickcrete's stone veneer morter, and some of the sand pieces were just too big, causing the auger to grind/pop. When this happened, the auger would jam, and twist the drill. Inevitably once the large piece worked its way through, it caused the tip to plug. (Make sure your sand has been properly screened) - You always need to have one hand on the grout gun. It will spin over, and spill if you let it go. The two best grab points are the handle, and the auger tube behind the hopper. (Where it chucks into the drill.) - Using a hammer drill is recommended. When you press the drill into the grout gun, the hammer action will act as a vibrator, and helps the grout to flow better. (No need to make the mixture soupy) - Run some water through before adding your grout mixture. It helps to prevent initial clogs. Tip modification: The supplied tips would work fine for a uniform grout joint, but the stone veneer chewed up the smallest tip, and I needed something smaller and more flexible. I cut the end off of a normal grout bag, and used a hose clamp to fasten it to the largest provided tip. It ended up working really well, allowing me to fill small and large cracks as well as corner joints. Handle/Stand modification: Having a third hand to help with filling the hopper would be nice, so I added a stand. Using a heat gun, I heated up a 3/4" piece of pvc, cut it, and bent it to make the stand. Now my hopper stands upright when I am filling it, or when I set it down to tool the joints. (I did have to remove the stand to fill any joints that were close to the ground.)

Augur jams, hopper flips, spills mortar. Not a viable tool, would take 3 hands to use properly.

It works great. You need to have a creamy mortar, not some junk bag mortar from home Depot. Did 2700 sq ft of thin brick veneer grouting in 6 days. If it’s to heavy keep your day job. It’s not heavy. Fireclay is also really good for the creamy texture needed. If you’re in the trade. It works really well. Yes it need to be a little wet, but not falling out of the joints I wish the sold more plastic nozzles separately.

Unwieldy. Have to mix the mortar much too thin for it to work at all.

I purchased this item for a minor repair/replacement of mortar between some bricks. As others have indicated there are some concerns with nozzle plugging and yes this happened in my case but adjusting the mortar to a slightly thinner paste it managed to push the mortar well into the gaps between them the bricks. So yes it worked. Now let me say that the quality of manufacturing is questionable. The unit I received may have been a used returned item, rust stains on the silicon used to seal the hopper. The auger grinds as it rotates in the cylinder right out of the box. Disassembly for cleaning requires snap ring pliers to remove the auger. There is no way the unit can stand on its own to fill the hopper or to just set it down during the work process without it tipping over and spilling the mortar. Read the negative reviews for other problems and issues and some possible solutions or work arounds.

Using for a medium sized home tuck pointing repair project. Makes things quick and easy. For those thinking of buying, here is how to get around issues in the negative reviews 1. Clogging problems - I found the first fill tends to clog at the nozzle. I simply unscrew the nozzle, tap out the mix in there, re screw on, and it works perfect. You don't have to make your mortar soupy. 2. To those saying you need three hands, or it spins. I have no idea how that is happening to you. 3. To those complaining about cleanup: masonry is like that. Clean your tools at the end otherwise mortar dries in the tool. Product works better than I anticipated based on the reviews.
