DIY How to Set Up & Use a Caulking Gun
Caulk is a thick substance used to seal seams, joints or other crevices within a building. Once applied, a bead of caulk helps protect the seam from moisture, insulate the interior and reduce noise transmission. One of the most commonly used types is silicone caulk, though polyurethane and acrylic-based caulks are also available. The caulking gun, which is required for applying the caulk, is simple and inexpensive, but invaluable to any dedicated home repairman. Does this Spark an idea?

Preparing the Gun and Caulk Tube
-
1
Insert the end of the caulk tube's nozzle into the hole on the side of the gun's handle at a 45-degree angle. Cut the tip off by squeezing the gun's trigger firmly.
-
2
Locate the needle on the underside of the caulk gun's barrel. Push the needle into the tip of the caulk tube to puncture the inner seal. You will hear a distinct popping noise once it has been punctured.

-
3
Lay the tube in the barrel of the gun, back end first. The tube should sit completely flat and the nozzle should protrude from the hole at the front of the barrel.
-
4
Squeeze the trigger gently and listen for a slight gurgling noise, as this indicates that the caulk is ready for application.
Using the Caulking Gun
-
5
Hold the tip of the nozzle against the beginning of the seam or joint.
-
6
Apply the caulk bead by gently depressing the trigger and moving the nozzle down the length of the seam.
-
7
Release the trigger once it cannot be depressed any further. Once released, the plunger at the back of the barrel squeezes a new supply of caulk forward.
-
8
Continue application of the caulk where you left off.
-
9
Remove an empty tube of caulk from the gun by pulling back the plunger and lifting it out of the barrel.
