Mold and mildew in a tub is unsightly and you don't have to settle for it any longer.  In a matter of minutes, you can have the old caulk removed and set your path on a fresh new look in your bathroom.

How to Caulk a Tub

Remove Old Caulk

Remove old caulk from the tub before adding a new application. Do not add caulk on top of the old caulk or the mold and mildew will bleed through.  You can use a utility knife to gently remove the old caulk

Add Painter's Tape

Once the old caulk is removed, clean and dry the area you plan to re-caulk. Now, add painter's tape so you are able to make a straight line when apply the caulking.  The painter's tape will also help you avoid any mishaps of adding too much caulk to the area.

Choose the Right Caulk

There are many different caulks options in the aisle.  Read the label and make sure you get a silicone acrylic bath caulk. Depending upon the color you want there are clear, white and options that can be painted.

Apply It

Place the tip of the caulk between your two painter's tape lines.  Try and force as much caulk into the gap as you can, filling up the area between painter's tape.  Once you've applied a full line of caulk, follow up with your fingers and press the caulk down into the grove.  Then, remove the 2 pieces of tape.  Finish it off one more time by running a different finger (a clean one) across the caulk grove.

Now Wait

Let the caulk cure for 24 hours before using the shower or bathtub where you have applied the caulk. Humidity levels in the home can slow or speed curing times.
