I almost didn't make it thru the learning curve of this tool. I purchased it to grout the joints of the top caps of a 138 foot retaining wall with dye colored pre-mix mortar. First question: how do you fill it? I found that a piece of angle iron worked very well with little mess. The first six times I tried it, I would start to squeeze it out and the tip would act like it was plugged and stop flowing, I then would clean it all out with water and try again. Here is what I discovered: The plunger was shipped in a "loose" mode and needs to be adjusted to a snug fit inside the barrel by tightening an adjusting nut. If you do not do this, as the trigger is squeezed, the water goes around the plunger creating a mixture that is to dry to flow almost instantly. Once I got thru the "learning curve", I don't know what I would have done without it! It was awsome! and worked perfectly the rest of the project. I hope this helps.

This gun is NOT for tile installation. It is for applying grout joints to real or cultured stone / real or veneer brick on vertical walls. We have loaded and squeezed spec mix, sanded grout, Type S mortar, Type N mortar and regular tile setting mortar through this gun for 1/4" - 1" grout joints. The process is always a little messy, you have to clean the gun between loads and it is a little difficult to retract the pressure rod after the load is dispensed- but this is an essential detailing tool for any real masonry tradesman. This isn't really a replacement for grout bags, but useful in corners and hard to reach areas where grout bags are too awkward to handle, or up on a ladder where both your hands controlling the grout bag (and not hanging on to the ladder) can be dangerous.

A little messy but when working with mortar things can get messy. The applicator worked as designed and saved a ton of time over a mortar bag. Recommend it to any one time or frequent worker who works with mortar. Best 58$ i've ever spent.

Four stars because the item is very well made, and a great idea. It may work well with mortar and the bigger opening, but sanded grout (without hydrated lime) will not flow. Water is squeezed out plunger end, much like cheese curds in a cheese cloth, until a rigid lump of grout is left in the cartridge. I didn't try the hydrated lime thing, ain't got time for special mixtures a quart at a time. Same grout consistency flows through grout bag much better; don-know why, maybe keeping every thing, water & all, in bag is the answer. Too bad, I hate those grout bags. I really wish it had worked.

I had high hopes for this product because of the amount of tuckpointing my 50+ year old limestone ranch house needs. I have been using Rapid Set (brand name) mortar mix in the applicator. The trouble is the mix is designed to set up in 10 or 15 minutes so you have to work fast, thin the mixture a bit and use very cold water to slow things down or the applicator will clog.

For occasional use this product is just fine. I now understand why some of the other units offered (more expensive) have a drill or motor powered augar to keep things flowing. When you get a clog, your work stops and it can be a mess to clear and start over, also tiring & tedious if you are on a ladder.
The mixer wand that comes with the applicator is very nice, I'm very glad it was included. Tip: use some heavy grease or lube on the inside lip of the nozzle cone so it won't stick to the barrel cylinder, I learned this the hard way when it came to the first clean-up time.

I am sure this is an excellent tool for the professional but not for the less experienced homeowner. Issue 1: In my case, I had to refill the barrel again and again even though it was still almost a quarter full. The reason, the plunger is too short, it does not reach nearly the bottom, as a consequence there is a lot of wasted material and a lot of washing. The professionals can afford waste, not the usual homeowner. Issue 2: What is it with the loose barrel? In one instance the barrel pulled up and left me with a lot of goop on the floor. In my view, they need to improve the design of this tool to make it more DIY friendly.

I purchased this tool to install grout between 18 inch tiles with 1/8" joints on a bathroom floor. I mixed sanded Polyblend grout to exact specifications. I put the grout into the gun tube and tried the "grout" tip cut to about a 1/4" opening. I had advanced the push rod sufficiently to feel increased resistance but no flow from tip. As I was carrying the gun to the tile area, some water started to drip out of the spout. When I tried to apply more pressure to release grout nothing came out. I switched to the very open "mortar" tip (black)and still nothing came out. Only one of the prior users warned against using it to install sanded grout. What I don't understand is how mortar (with generally coarser sand than in grout) could be pushed through the large (black) spout. On the bright side the kit sent came with the COX Turbo Mixer which really worked well for grout and thinnset, especially for the usual small batches that novices work with. The ones available in HD and Lowes leave unmixed portions in the bottom of the bucket and is much more likely to throw dry mix and wet mix out of the bucket if the drill over speeds. Unfortunately, I paid $84.19 for the kit delivered but I could have gotten the Turbo Mixer for $12 delivered which is the only part of the Kit that was useful.

I have never been so impressed by a tool. The quality and the usefulness are unsurpassed. It comes with two tips, one for large grouting operations and one for small groves. Whether the job is large or small this is the gun especially for professionals. It should work not only for grout but any material application you could think of. The material delivery and engineering of the Cox tuck point brings back the feeling "Made in America" use to engender decades ago.
