Rated 4.2 out of 5 by 6 reviewers.
Rated 1.0 out of 5.0 by It did not do the job I intended it for Granted, I bought the wrong type of gun. This gun won't work for stone/brick pointing. Neither did the correct gun, the Portland 1000. It didn't work any better. June 23, 2015
Rated 5.0 out of 5.0 by This product was excellent and the extra tips were perfect! I was finishing a tile install on an exterior of a home. This product made the finishing fast and easy. It was easy to load and the different tips were a great bonus. June 13, 2012
Rated 5.0 out of 5.0 by works great Good quailty, works great for what I need it for, Highly recommend also buying the follower plate. December 1, 2011
Rated 4.0 out of 5.0 by great job for my kitchen backsplash installed backsplash in my kitchen which was travertine and had a surface with lots of natural texture and holes, etc - didn't want to float grout in and screw up the finish. This grout gun worked nearly perfectly. Only detractors from getting 5 stars was the plunger getting stuck a few times and being really hard to move. Otherwise, easy to fill, easy to use, easy to clean. Mine came with a handful of tips. Using the tips is pretty hard though if you have a small grout gap to fill unless you can mix your grout without ANY chunks or lumps. I was using a 1/8" grout line and had to cut a much larger hole to get the grout through it so still had some cleanup to do, but that really isn't the gun's fault. also I vote against needing the follower plate that is recommended with this. Mine broke upon assembly but I was able to proceed with no problem without it. June 9, 2014
Rated 5.0 out of 5.0 by Great tool to speed up big jobs! Needed to grout in about 300 sf of stone veneer. Tried this bulk caulk gun rather than using a mortar bag. This thing works great and was able to push wet mortar, sand and all, in to the stone quickly. Nozzles could be a little stronger but it did come with two spares. Quality is excellent and evident in design and materials used. October 29, 2013
Rated 5.0 out of 5.0 by Exceptional Value Well Designed and Constructed. Purchasing the Accessory Loading Plate is Recomended November 19, 2013
