If your bathroom has dirty, discolored, or cracked caulk around your bathtub, shower or sink, it’s time to replace it. Mildew will easily grow in these spots–especially where your bathtub meets the floor–so re-caulking is a necessary task to complete about once every 10 years. To remove the old caulk, use a putty knife to help peel back the caulk. Once it’s all removed, clean the surface with bleach or rubbing alcohol to be sure any old mildew is now gone.
To apply new caulk, load white silicone caulk in a caulk gun and cut the tip to a 45 degree angle. As you squeeze the trigger, move it along the surface keeping a constant pressure. You can clean the tip of the gun between applications with a paper towel. When you’ve finished applying the caulk, run a wet finger over the surface to smooth it out and remove excess caulk.
Lastly, follow the instructions on the caulk container for drying times. Now your bathroom’s set for another 10 years!
