AWF PROMortar Pointing Gun, 1 Quart (32 fl oz.) Capacity, 12:1 Thrust,2 Nozzles, Adjustable Pusher Plate, AWF-Pro

I did attempt to purchase this before previously, when I had no luck with the mortar bag, but it was backlogged on shipping, so I cancelled that first order. I tried another tube mortar gun after that and could not get the mortar to come out no matter what mix I tried.I then tried to purchase this one again and it arrived quickly and as promised.The only thing I would suggest to the manufacturer to update would be a screw on adaptor rather than press to fit. Luckily, I placed the adaptor I was going to use on the tube because I don't know if I will ever get that one back off.The Mortar Gun itself is sturdy, well-built and with the tube filled it is still easier to use than the bag.I cleaned in between mixing new batched, which is easy with cold water from a hose, so that there is no hardening of residue.You do need to test the fit for the plunger out of the box. I tightened a bit, with the included wrenches before I started and had absolutely no problem with blow back, or application, even with a bit thicker mix than I had previously tried.I am using to mortar a thin brick system of 50 sq ft, and the only reason I wasn't done in 1 day, is I ran out of mortar mix, wasting time and mix trying the other suggested and advertised systems.Buy this one! Even comes with a handy mix tool.

I purchased this mortar (grout) pointing gun to use (initially) for grouting travertine mosaic wall tile I had installed. I would be using non-sanded grout because of the narrow width of the spaces between the mosaic tiles (spaces varied from 1/16” to maybe 3/16” in width).In order to do a ‘test run’ to determine how well the (unit) worked, I mixed up a small batch of grout and made sure it was a consistency that would ‘flow’ well through the nozzle tip and proceeded to load the tube on the pointing gun – maybe filled ¼ of the tube.Pressed the plunger into the tube until in contacted the grout and then placed the pointing gun ‘vertically’ and squeezed the trigger several times to remove any air pockets and the grout initially started to flow. Started grouting the spaces between the tiles and maybe covered 2-3 lineal feet when I noticed the trigger would no longer move…I had reached the end of the tube. That didn’t make any sense since the amount of grout I had in the tube should have easily done a small section of the wall. Depressed the ‘release’ on the plunger rod and started pulling back on the plunger. Low and behold, lots of grout was coming out from behind the plunger (it had squeezed past the rubber seal on the plunger and was now behind the plunger).Apparently I (incorrectly) assumed that the rubber seal on the plunger had been ‘adjusted’ to the proper diameter by the manufacturer before they boxed up and shipped the unit…I was WRONG! Ended up throwing away that batch of grout and giving the unit a thorough cleaning (that took more than ½ hour to remove all the grout that had gone everywhere but where it should have). There are ‘limited’ instructions included with the unit (actually NONE), but the ‘note’ on the listing indicated one could ‘adjust’ the rubber seal to account for wear – by tightening the nuts on both sides of the plunger assembly and ‘squeezing’ the rubber, forcing the edges to protrude further and (hopefully) contact the inside ‘sides’ of the tube. I tightened these nuts squeezing the rubber seal and the rubber seal expanded outward to where in now contacts the sides of the tube.I do not know if the ‘difficulties’ I encountered were because I was using non-sanded grout…would it work better if my project had required ‘sanded’ grout or mortar, I do not know.I will retry the unit this coming weekend to see if the unit functions like I hoped it would and will update my ‘post’ afterward.

Great product and exactly what I needed for my project that involved replacing a temporary board with a permanent fireplace mantel that was installed after the stonework was completed.As anticipated, removal of the temporary board broke off some of the mortar work. Installation of the new mantel created an additional 1/4” gap. Placing cement by hand and trowel was not feasible and using the “caulk gun” for the cement worked perfectly. It was like piping frosting on a cake.Hints-Be sure to test your viscosity. Make sure the mix isn’t too thick. Adjust the rubber gasket so that it is not too snug as pulling it back out can be really challenging if too tight. Wrap the back end with a towel as drops of water will fall back on you. That’s the trade off when not expanding the gasket overly tight. Keep either a wire coat hangar or #12 electrical wire to break free any plugs by inserting into the tip. I used a bucket to mix the cement and then a paint stir stick to load the cylinder. Fit the tube perfectly. Again, perfect product!!

In the U.S. southwest, stone walls are ubiquitous. Although some are built by stonemasons and skilled craftsman many are not. Such is the case with the walls around three-quarters of my home. The laborers cut corners by mixing too much sand in the concrete mix, filling the space between the rocks interior to the wall with dirt or worse, nothing. Repointing the wall is a job in and of itself but filling the voids is much more difficult. However, the Pointing and Grout gun has been a lifesaver and works well in filling the voids and large openings in the walls face. The gun is well built except for one issue. I have to use a mallet to unseat the tube from the gun every time the cylinder needs to be refilled. The nozzle at the end of the tube becomes wedged in the gun's frame. Thus the four-star rating. Despite this aggravation, I'd recommend the gun. Hint, before filling the gun the first time, follow the manufacturer's instructions and tighten the plunger.

DOES NOT WORK well. took it apart to see why. the tube where you put the grout had a big burr on both ends of the tube. wouldn't push the grout out. Sanded the burr on the inside of the tube. now i could adjust the plunger to get it to push the grout. had to thin the grout too thin to get it to go through the gun. was too thin to do vertical joints. will try thicker mix and give a review if it works. this is a second review. disregard the first review.
