Caulk Tools and How to Load a Caulk Gun.
A successful caulking job begins with having the right tools. First and foremost, you need a good quality 100% silicone caulk that will flex and won't shrink or crack over time. Second, a good caulk gun, some clean up and application materials are important as well.
Caulking materials you may need:
Start by cutting the tip off your caulk tube. You can use scissors or some caulk guns have a hole in the handle for cutting the tip off. Cut the tip at an angle for better application.
Poke the stick on your caulk gun into the tube a few times to break the internal seal. Alternatively, a straightened wire coat hanger will work as well.
Pull back on the hooked rod on the caulk gun (some rods must be rotated 90 degrees to release the notches.)
Pull the rod all the way back.
Insert the caulk tube base first. Lay the tip inside the notched end of the caulk gun.
Now you're ready to start caulking. Squeeze the trigger to start the caulk flowing out of the tube. If you've never caulked before, practice on the inside corners of a cardboard box to get the feel of using a caulk gun and caulking a joint.
