  • Silicon caulk remover

How To Recaulk a Bathtub or Shower: Remove the old caulk

Step 1: Remove the old caulk

Using a utility knife, cut along the edge where the caulk meets the tub. Scrape out all the old caulk.

Step 2: Clean the area

Pour a capful of bleach into a small bucket of water. Using a toothbrush, scrub the area with your bleach solution to help prevent mildew and mold from returning.

If you are having trouble removing all the caulk, spread some silicon caulk remover on the area and let it sit for several hours.

Allow the area to dry for at least two hours.

Step 4: Fill the tub

To make cleanup easier, put strips of painter’s tape along the tub and wall bordering the area you will be caulking.

Cut the tip off the tube of caulk at the point indicated. Starting at one corner of the tub, slowly squeeze the caulk into the gap in a smooth and even line.

Don’t be cheap. Invest in higher-quality caulk if you don’t want to have to replace it again in a few months.

Step 6: Even out the caulk

Wet your finger and run it along the new caulk to smooth it out evenly. Wipe any caulk that gets on your finger onto a damp rag.

Great tip about filling the tub first...I've never heard that from anyone! And taping off with painter's tape will be great - thanks!
