Once the joint is cleaned out and masked, you're ready to caulk.
- Open the caulk tube by cutting the tip at a 45 degree angle and puncturing the inner seal with a long nail or wire. Many newer caulk guns have built in tip snippers and puncture wires.
- Apply the caulk at a 45 degree angle between horizontal and perpendicular.
- Make sure to squeeze hard enough to get the caulk fully into the joint.
- Work at a speed that is slow and consistent. The smoother you make the joint to start with, the easier the job will be.
