You probably won’t be using caulk for drywall installation or repair, but you will need a good caulk gun if you plan to install any access panels. That’s because even though access panels are generally designed to fit into a precut hole, they are usually held in place with construction adhesive. This can be applied with a manual caulk gun if you’re looking to save some money, but those willing to spend a bit more can get an electric one which makes the task considerably easier.
Makita makes a Cordless 29 oz. Caulk and Adhesive Gun which, like everything else on this list, is powered by its 18V LXT battery system. This can deliver up to 1,100 lbs of dispensing power and has five different dispensing speeds which are controlled by a dial to make it easy to get a nice consistent bead. It also has a rubberized soft grip handle and a built-in LED to help you see what you’re gluing.
There haven’t been many professional reviews of this tool, but it has a 4.7 out of 5 on Home Depot’s website. Reviewers praised the for its ease of use and the consistent flow of pressure. The only criticisms were that it was a bit expensive and would therefore only be worthwhile for large jobs where you would get plenty of use out of it.
