Caulk Guns deliver caulking or construction adhesives to seal cracks and hold various construction materials in place. Caulking guns come in two varieties, battery-powered and hand-powered.
A hand-powered caulk and adhesive gun uses a large squeeze trigger to drive a plunger into the back of the caulk tube. These hand tools use the term thrust ratio to describe how far the plunger moves with each squeeze. A thrust ratio of 3:1 indicates caulk guns that require a lot of effort to use, while a 10:1 or 12:1 gun is far easier to dispense. Hand-powered caulking guns' primary advantage is that you can dispose of them after you finish the project if you just do casual DIY homeowner work.
Caulk guns come in three major varieties, based on the size of the tube or bag that they dispense. Most tubes used around the home have 10 ounces of caulk, which is more than enough for most simple home jobs, and usually lay down between 25 and 50 feet of sealant, based on the size of the bead you leave behind. Quart-sized caulking gun tubes contain enough for caulking entire rooms. Sausage guns hold loose bags of material that look like packed sausages. Sausage guns have the advantage of being able to draw bulk caulk or adhesives from a bucket for extra jobsite versatility.
For precision work, look for a gun with a non-drip rod that stops dispensing once you release the trigger. Guns with built-in nozzle cutters or seal puncture tools save you time and are safer than using knives to cut.
Caulk guns make your sealant jobs go quickly and offer precise beads that conserve material. They come in a variety of configurations to meet your individual needs. Grab a caulk and adhesive gun and finish your projects fast and with beautiful results.
