If you have an older home, or you’ve been in yours for a few years, the caulk in your bathroom is going to start cracking. No matter how clean you keep your bathroom, you are going to get mold and stains if you do not recaulk around the tub. Check out this helpful tutorial by Betty at Hometalk for caulking tips:
-Use a utility knife to remove the old caulk
-Spray some Lift-Off Caulk/Silicon remover onto the entire area you scraped off the old caulk.
-Apply steady pressure to your tube gun as you move along the tub seam.
As soon as the seams are filled, smooth the caulk with a wet fingertip.
