  • Around window and door frames
  • Around faucets, water pipes, ceiling fixtures and drains to prevent water damage
  • Over gaps between stationary building materials measuring less than a quarter-inch wide

  • Before you apply caulk to a window frame, door frame or other surface, practice on a disposable surface to get a feel for the caulk gun. Then, move on to the actual application.
  • Clean the area to be sealed. Remove old paint and caulk, and dry the area thoroughly.
  • Apply the caulk at a consistent 45-degree angle. Avoid stopping and starting for the best application possible.
  • Apply enough caulk so the compound sticks to both sides of the gap and seals it thoroughly.
  • Clean up oozing caulk before it dries.
