Home Upgrade: Use Caulk to Seal Grout Cracks

Cracks in the grout around your tile and sink areas make a home look a little too lived in. For $4, seal those cracks with caulk.

I had small cracks in the grout around my kitchen sink and tile backsplash. In fewer than 15 minutes, I used caulk to seal the cracks and have a completely refreshed tiled area.


This picture shows what my grout looked like – via



  1. Caulk – In the same color of the grout you’re repairing. I used GE White Silicone caulk from Home Depot. Make sure that you get caulk that does not require a caulk gun.
  2. Towel
  3. Access to a sink or water


  1. Cut off the tip of the caulk dispenser. Some caulk might ooze out due to pressure. Just wipe it away with the towel.
  2. Squeeze the caulk onto the cracked grout.
  3. Spread the caulk with your finger, pressing it into the cracks.
  4. Wipe away the excess caulk with your towel. Repeat on all cracked areas.
  5. While the caulk is still wet on your hands, use water to wipe it off.
