Things You'll Need:
- Surface Cleaner
- Utility Knife
- Alcohol
- Tube of Caulk
-
Step 1
Choose your caulk first.
Silicone should be used on fiberglass. It is soft, east to use and can be removed very easily; surface must be completely dry to use!
Polyvinyl acetate can be used on any surface and is completely mildew-proof. -
Step 2
First and foremost, you must clean the surface with soap scum remover and a sponge.
-
Step 3
Use your utility knife to cut the old caulk. Be very careful to angle the razor so that you do not scratch the tub, especially if it is a plastic or fiberglass.
If the caulk is too hard, you can heat it up with a hair dryer. -
Step 4
Wipe down the joint with alcohol and allow it to dry; this will remove any remaining soap scum. Be sure to get rid of any little pieces of caulk under the edges of the tiles.
-
Step 5
If the area is wet due to a leak, wait overnight before caulking to ensure good grip and complete finish.
Prepare your caulk tube by cutting a hole in the tip of the tube; do not cut the hole too large as this will result it over caulking. -
Step 6
Apply a bead of caulk into one of the joints. Use your finger to press the caulk evenly into the joint. If you have applied the right amount of caulk, the smear will be smooth, neat and even.
If you went a little caulk happy, wipe the caulk out of the joint and try again. -
Step 7
You must work quickly because caulk tends to dry fast and may clump up! Do the entire tub in one sitting to ensure a smooth, complete finish.
