From the Manufacturer

Put an end to the tedious, fatiguing chore of applying caulk with a manual caulking gun. The DEWALT DC545K Cordless Caulk Gun provides a much faster, better, easier way to dispense a wide variety of caulks, sealants, and adhesives. Powered by an 18-volt battery that delivers 650 lbs. of pushing force, the DC545K will apply the thickest, stickiest, most stubborn caulk and sealant, and all you need to do is squeeze the trigger. This tool is indispensable when caulking around windows and doors, applying construction adhesive to floor joists, patching chimney flashing with roofing cement, and laying a bead of sealant around tubs, showers, glass block and tile. The cordless gun is equipped with a 360-degree rotate-able chamber that accepts 10-oz., 1/10 gal., and 300- to 310-ml cartridges. Its adjustable set-and-forget variable-speed control allows you to consistently dispense just the right amount of material at the desired rate and speed, resulting in superior bead control. And the auto-reverse feature eliminates messy drips and reduces waste by automatically drawing the caulk back into the nozzle the instant you release the trigger. The DEWALT DC545K Cordless Caulk Dispenser comes with one 18-volt battery and a one-hour charger. It’s backed by a DEWLT 90-day money-back guarantee, full one-year service contract, and three-year limited warranty.

5.0 out of 5 stars A few usage tricks, May 27, 2010

This review is from: DEWALT DC545K 18-Volt 310-ml Adhesive and Caulk Gun (Tools & Home Improvement)

This gun has alot of torque and will dispense thick adhesives like liquid nails quickly and evenly without the jaggies of a typical manual caulking gun - you get one nice continuous bead. To keep panel to panel consistency, I glued a cheap countdown stopwatch on the back of mine so that I could dispense a known amount of material, i.e. 8 seconds worth on a 4x4' panel, 16 seconds for a 4x8 panel - basically when doing repeated work you get excellent repeatable results and can go through material rapidly saving alot of time and sore hands from manual caulking guns. If your stopwatch works as a count-down and up modes, you can time your first panel, then set that time for each additional panel.

For thin material such as latex caulks I advise a very small opening in the tube - the dispensing rate is so fast that the thin hole you make is all that holds back the dewalt from squirting the whole tube out. Since the thin material comes out at high pressure due to the small nozzle, it expands in width afterwards and makes a wider bead than initally dispensed, so downsize the guides on the plastic tips about 2 sizes and you will get close your desired width. If you have never used a particular caulk before, start by just snipping off the very end of the plastic then cut back more if needed. It's easier to snip off a little more of the tip if it's too small but you can't cut it smaller if its too large to begin with! In my kit I keep a pair of wire cutters to snip the end of the tubes wider or at a sharp angle.

One fully charged XRP battery can empty 40+ tubes of liquid nails with power left over. It's a better tool for adhesives than caulks just due to the viscosity difference, but with practice it can force caulk into small gaps with ease. Re-caulking a bathtub can be done in a single trigger squeeze leaving a professional finish.

Well made heavy duty caulk gun. Not for standard caulking jobs however. Too costly, too heavy, and unnecessary for typical jobs. Great when you have a lot of caulking to do or with high viscosity caulks.

I have had a Ryobi for 4 years a cheap 38.99 cheapo, worked great till I dropped it off the roof for the 100th time, So I thought I should up grade to a better one,The Dewalt DC545K... nothing but problems, the brass battery terminal piece bent over I straightened it up a few times and made it work wiggling the battery to make it work, But now it is flat bent over again..... I give up I am returning it and buying the Ryobi. Mabey China fake.. Would explain why it sucks..
