Preparing the Caulk Cartridge for Loading

What happens here

Before loading the caulk cartridge into the gun, it must be properly prepared. First, take a utility knife or the built-in cutter found on many caulk guns and carefully cut the nozzle tip at a 45-degree angle. The size of the opening will determine the width of the caulk bead, so choose an appropriate cut for your project. Next, use the long, thin rod often attached to the caulk gun or a long nail to pierce the inner foil seal located at the base of the nozzle inside the cartridge. This action breaks the seal, allowing the caulk to flow freely when dispensed.

Goal: This step provides expert guidance on preparing a caulk cartridge for use by cutting the tip and piercing the inner seal. (Not explicitly shown in the video).
