Rated 1.0 out of 5.0 by keith tryed it
bought this for grouting 500 sq ft of 18x18 " tiles 3/16 grout lines with Mepei Keracolor S.in 25 lb. bags.
that will do around 380 sq ft of tile per bag, mixed 1/2 bag per Mepei instructions, was working inside air conditioned house @ 75 * . it works great on the first fill of the gun. but remember as your are working, the grout in the bucket is starting to set up a little more as TIME goes on. 2nd fill was ok too.
3rd fill did not want to flow out the gun .. too dry. and remember you CAN NOT add more water to the grout to thin it out. so I guess you either mix smaller amounts/ work fast. or have 2 people. one using the gun to fill the grout lines and the other to finish them off with the float . that might work. I stopped using it after the 3rd fill because the already mixed grout in the bucket was getting thicker but still useable, but not with the COX gun. finished the floor the old fashioned way. Slop it down clean it up

Rated 4.0 out of 5.0 by Mike Works well, could use better instructions
Want a device to help you make quick work of mortar repair? This is it, but there is a caveat:
Your mixture needs to be pretty runny, but just adding water to sand/mortar mix likely won't be enough. The water will tend to get wrung out of the mix and it just plugs up in the applicator. So you need to add something to condition and plasticize the mixture such as an extra part of lime to keep the sand suspended in the mix even when it's runny. This has the added benefit of softening the final set product, which is helpful for the longevity of old, fragile brick you're likely to be working with if you're looking at a tool like this. The only problem is that the instructions don't explain this at all, so DIYers are likely to get a little frustrated like I did--unless you learn from my mistakes.

The gun worked very good, we were doing it by hand and it took forever, with the Tuck it is going much faster and easier on our skin.

Rated 5.0 out of 5.0 by cityboy Beats Squeezing a Grout Bag!
I was using a grout bag to grout stones on a vertical wall. I started to use a grout bag but after hours of grouting I felt like my hands were milking a cow for days!!! A grout bag is old school, it’s the “udder” way of doing grout! I saw a grout gun on a home improvement show and ordered the COX 32oz caulking/grout gun. After a few tries and learning how to get the correct grout consistency, it worked great. The grouting area that took literally hours to grout, now took just over 20 minutes. The gun did need some adjustments which are mentioned in the instructions (which I didn’t read completely at first–because I’m a guy), but after reading the instructions and making adjustments to the grout consistency and plunger tightness it worked as advertised, which was fantastic. Works very well for vertical grouting.

Rated 4.0 out of 5.0 by Arthur Works well when used properly, here are some tips!
This is made pretty well but I struggled with it at first. Here's what I learned. I'm using it to tuckpoint brickwork so I'm using the large nozzle. Mix your mortar first and let it sit for 30 mins to begin activating, then add water to get it to the final consistency. Make it pretty soupy so it flows easy. Next fill the tube and then clean the end of the tube and the plunger. I kept a bucket of water and a rag next to the job to dunk the plunger and wipe the end of the tube. If you don't do this every time you load the sand gets between the plunger and tube and allows water to leak past the plunger. It will squeeze all the water out of your mortar and then it will compact in the nozzle. The same goes for the joint between the tube and nozzle, sand there will cause a leak point for the water.

Rated 1.0 out of 5.0 by Mason Good idea but I was not able to get it to function properly
The internet description of the mortar/grouting caulking gun seemed to be just what I needed. I attempted to use it about 6 times and could not get the appropriate mortar consistency. The mortar was either to thin (runny) or to dense to flow from the gun. On one attempt, I was able to get about three hand squeeze pumps, so I climbed the ladder and the next squeeze, the mortar compacted in the barrel again. I understand that the problem was mixing but it was taking so much time to experiment that it was quicker to place the mortar with a pointing trowel. I sent two e-mail messages to the manufacturer explaing my frustration in trying to achieve the appropriate water/mortar ratio and mixing time that it was not worth my effort. After two weeks the manufacturer did not respond to my messages, so I returned the caulking gun back to Home Depot and the Home Depot representative was very understanding and returned my money with no problem. I only had to explain why I did not want the caulking gun. I would have thought that it would have been in the best interest of the manufacturer to help me learn the art on mixing but apparently they had no interest in my problem- they could have at least tried.

Rated 1.0 out of 5.0 by Mark Messy, poor performance, do not buy (how do they even carry this product)
I was skeptical because mortar has a consistency that does not lend itself to a "caulk gun" application, but I figured why would HD carry it if it didn't work. It doesn't work and drips mortar laced water everywhere. I returned it after creating a huge mess... and I am very handy and have worked with cement and mortar in the past.

Rated 4.0 out of 5.0 by 1951 Allows for clean, easy vertical application of grout with minimum clean up time.
Great customer service and fair turn around on shipping for a non stock item.
