Large Size Auger Electric Mortar Grout Gun Big Augers Portable Pointing Grouting Caulking Sprayer With 3 Nozzles (Without Electric Drill)

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.
