1. Remove the Old Caulk

You may need to use a utility knife, scraper and plyers to remove the old caulk.

Use a utility knife and cut along the top of the caulk where it touches the tub or shower surround.

Use a scraper to loosen the caulk from the tub.

2. Clean the Tub and Surround.

Your going to have to use a little elbow grease here. You can use your scraper but be careful not to scratch the tub or surround.

3. Apply the New Caulk

There are a few different ways to apply the caulk. If you are a professional and use a caulk gun every day you may be able to apply a straight perfect bead the first time. Most of us will need to use a Caulk Tool to help us get it perfect.

You can also tape off the surround and tub, I chose not too. If you decide to use tape make sure you leave enough gap for the caulk to be able to attach both the tub and surround.

4. Scrape the Caulk Straight

I like to use a Caulk Tool for this, but you can use your finger. If you decide to use your finger remember to wet your finger first and keep a few paper towels nearby.

If you used tape make sure to remove it before the caulk has time to dry. Refer to the manufacturer’s label for drying time.

5. Allow Caulk to Cure

You will need to allow the caulk to completely dry to cure. Read the manufacturer’s label to find out the recommended drying time.

Now your bathtub or shower should look brand new! It really isn’t too hard or complicated, this is a task that every homeowner could do on their own. Good luck on this one and your next home improvement project you do.
