How to Apply Silicone Caulk


Silicone caulk is perhaps one of the quickest and most practical ways to seal a home. It's great for working around doors, windows, or even in the bathroom. The caulk provides a great adhesive seal that bonds to the surface and keeps moisture out of unwanted areas. Additionally, caulk comes in many colors to match those decorating projects you are working on. Whatever the project, followi a few basic steps and you will soon know how to apply silicone caulk, and feel good about your work.

Things You'll Need

  • Silicone caulk (one tube)
  • Caulking gun
  • Wire cutters
  • Rag or towel
  • Turpentine (if needed)
  • Small bucket of water
  • Clean the area to be caulked with the rag and water.

  • Cut a small piece of the end of the nozzle on the tube at a 45-degree angle. Cut just enough to let a small amount or bead of caulk exit the tube when squeezed.

  • Load the caulking tube into the caulking gun with the nozzle away from the trigger.

  • Hold the caulking gun at an angle to the crack to be filled with caulk. Gently squeeze the trigger while pulling the gun down along the crack. Move the gun at a steady pace to allow a steady bead of caulk to fill the crack. Work at a pace of about 3 to 4 inches at a time and release the trigger and pull it again.

  • Repeat step 4 until the entire crack is sealed.

  • Gently run a clean, damp rag down the crack with the caulking in it to force the caulking down into the crack and seal it from side to side.

  • Use a small amount of turpentine and the rag to clean up any silicone around the crack or other areas, if necessary.

Tips & Warnings

  • Purchase caulking in a squeezable tube and apply the same steps above without using the caulking gun and receive the same results.
  • Avoid contact of the silicone caulk with the skin.
