DEWALT DC545K 18-Volt 310-ml Adhesive and Caulk Gun

Needing a tool to apply adhesive caulk to the expansion joint on my pool I bought the DC545K. The construction grade adhesive was so dense that pulling on a manual caulk gun with two hands produced a pitiful bead. With the DC545K it was a problem of it coming out of the tube to fast and expanding wide. Fortunately the DC545K has a dial on the back so you can adjust the rate of speed of the caulk leaving the gun. This adjustment is a must have. The holder for the tube is metal and swivels so you can adjust the angle without having to swing the gun with the battery at an angle. There are two triggers. The top one releases the plunger for the tube so you can insert and remove the caulk tube. The bottom one starts and stops the gun. When you release the trigger the plunger backs off slightly to release pressure on the tube. On other models like the Craftsman C3 this backoff is quite dramatic and can make starting and stopping tedious. DC545K has this down pretty tight so you hardly notice. On the end of the tube holder is a metal probe for puncturing the inner tube liner (useful add on). Mine came with one battery and a charger. The quality and construction makes this a serious tool to consider. I would say worth the investment.

Quality tool. Pricey, but it seems all electric caulk guns are.

It's great for large jobs that require caulking. For small jobs its not as easy to use becuase of the amount of caulk that will continue to come out at the end. I used it for my crown in 2 rooms while I was on scaffolding and it was a huge help and reduced my caulking time by a good amount not to mention my hand did not hurt afterwards from squeezing a small caulk gun all day.

Dewalt has done it again. They make the best cordless tools! The caulking gun works great. Love the speed dial to control flow. The only complaint is over priced for bare tool, but glad I spent the money.

Please note that I am not a professional contractor. It would be better for me if the auto reverse feature was adjustable. As is this gun would continue to dispense caulk for a few to several seconds after releasing the trigger. If it were more aggressive with the reverse function this may not happen. It is high quality and speed adjustment set knob is great.

This tool works great. When you want to stop the flow of product it even backs off the plunger.

The only way to caulk is to buy a Dewalt gun and go to work. I've caulk the entire inside and outside of my log cabin with mine. It's soooooo much easier with this gun.

Must have for my windshield business. Saves so much time and energy. When working with thin material like silicone, set speed slow, when trigger releases, so does pressure.
