34 oz. Manual Bulk Applicator-Caulk Gun is rated 4.2 out of 5 by 6.
Rated 5 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Exceptional Value Well Designed and Constructed. Purchasing the Accessory Loading Plate is Recomended
