1. Key Features to Look For

You need caulk that works well outside. Here’s what to consider:

  • Weather Resistance: Choose caulk that can handle sun, rain, and snow. Look for caulk labeled “exterior” or “all-weather.”
  • Flexibility: Your siding moves a little. The caulk needs to move with it. Look for caulk with good flexibility. This will prevent cracks.
  • Paintability: Do you want to paint the caulk? Make sure it says “paintable” on the label. This is a must.
  • Adhesion: The caulk needs to stick well to your siding and the surrounding materials. Check the label for information about what materials the caulk works with.
  • UV Resistance: The sun can damage caulk. Look for UV-resistant caulk to prevent it from breaking down.
2. Important Materials

Caulk is made from different materials. These materials affect how well the caulk works.
