Caulking for Standup Showers

Caulk is an important part of any building project, sealing off the joints between different building materials to prevent stains and moisture from settling in. This is especially true in a shower, where moisture can lead to mold and rot if it's allowed to get into the joints between the walls and floor. Sealing off those joints is relatively easy, but it will leave you without use of your shower for at least 24 hours.

Scrub brush
Bleach
Caulk with caulk gun
Razor knife
Long framing nail

Instructions

- 1
  Wet your scrub brush with bleach. Scrub along each line in the shower where one surface meets another. Take off any dirt or loose material. Rinse well. Let it dry for 24 hours.
- 2
  Set your caulk tube in the caulk gun. Cut away the tip of the tube with your razor knife, at a diagonal angle, making a hole about a quarter-inch across.
- 3
  Push a long framing nail into the hole to break the seal inside. Squeeze the trigger to push the caulk up to the tip of the tube.
- 4
  Hold the tip against the top of the first vertical line. Tilt the gun back at a 45-degree angle. Squeeze the trigger to begin laying the caulk.
- 5
  Move the gun backward along the line, continuing to squeeze the trigger, laying a straight line of caulk all the way to the bottom.
- 6
  Wet your thumb and run it over the new caulk line, from top to bottom, pressing lightly and smoothing it out.
- 7
  Repeat for each caulk line in the shower. Let the caulk set for 24 hours before using the shower.
