How to caulk like pro!

Caulking Tips: DiY like a Pro!

  1. This cartridge fits into a standard caulking gun. For clean application, cut cartridge tip near the end, at approx 45 degree angle.
  2. Surface must be clean, dry, and free of debris. Have some damp rags or a roll of paper towels within reach. Put down newspaper in case of carpet drip.
  3. To lay a professional bead, hold the caulking gun at apx 45 degrees. Spin the cartridge tube so the longest part of your tip is on the top side of the gun.
  4. Now gently squeeze the gun just a bit, and begin to drag a bead starting at the highest point. Only squeeze the gun if your bead is too small. Find a rhythm :)
  5. For a clean job, when laying a bead, "A little dab will do ya!" You can always go back and add more silicone.
  6. After applying and working the silicone, let it cure for at least 30 minutes (at room temperature) before using your appliance.

I need to seal the actual seams ON my metal, wood-burning stove. Will Stove Bright M230 High Temperature Sealant do this job well or do you recommend another product? (I also need a high temperature primer for use before I paint the stove.)
