Getting Started

• 1). Go to your local hardware store, or reputable stores like Home Depot or Lowe's, and buy a tube of waterproof silicone caulking. Also, make sure to pick up a caulking gun and caulking smoother. A caulking gun makes applying caulk easier and more accurate, and a caulking smoother will aid in the overall appearance of the final product.
  
  
• 2). Load the tube of caulk into the caulking gun. Remember to remove the protective seal at the tip of the tube.
  
  
• 3). Ensure that the gap you are about to seal is completely clean, dry and free of obstruction to you and your tools. Make sure that there is no dirt or dust on the gap.
  
  

Sealing the Gap

• 1). Use your tube of caulk inserted into your caulking gun to seal the gap. Do this evenly and neatly by applying uniform pressure to the "trigger" of the gun, and moving slowly along the gap from one side to the other. It is OK if the seal is a little sloppy.
  
  
• 2). Use your caulking smoother to smooth the gap out. This will make the gap uniform and appealing to the eye. Carefully "wipe" the caulking smoother in a slow uniform fashion across the seal for a beautiful finish.
  
  
• 3). Read the back of the tube of caulk and observe how long the caulk takes to dry. Wait until the caulking is dry and remove all slight imperfections with your utility knife. Make sure you have a sharp blade before cutting into the caulk, and try to remove small slivers instead of large chunks or the caulk.
