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. ### ⭐⭐⭐⭐ Review *by S***R on 28 October 2023* 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.) ## Frequently Bought Together - Large Size Auger Mortar Grout Gun Augers Caulking Gun With 5 Nozzles (Without Electric Drill) - Tahikem 3 Pack Tile Grout Masonry Mortar Bag, 12" by 24" Heavy Duty Tear Resistant Puncture Tip Cement Sealer Bag, Mortar Bag Masonry, Grout Bag for Tile Installation, Grouting Bag (12x24 inch, Blue) - Electric Mortar Grout Gun Portable Pointing Grouting Caulking Sprayer with 8 Nozzles (Without Electric Drill) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/511310053-large-size-auger-electric-mortar-grout-gun-big-augers-portable](https://www.desertcart.us/products/511310053-large-size-auger-electric-mortar-grout-gun-big-augers-portable) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
