1. Picking your tools

First things first, you need to get your tools.

When picking up your caulking for your shower, you're going to want to choose a Tub/Tile style caulk. From this category you can choose either:


A waterproof solution that is tough and flexible, but can be a bit trickier to apply. Silicone is more sensitive to uneven textures on surfaces, more difficult to remove, and does not allow anything to stick to it. However, its toughness will allow it to last longer, reducing reapplications. Silicon comes in clear, white, and almond.

Acrylic Latex:

A more forgiving material. It can be easily smoothed onto surfaces, and easily removed. However, it will shrink and dry harder, which can cause cracks. It will also require more frequent reapplications. Acrylic caulk comes in many colors.

Alongside your caulk and applicator, you will also need:

  • Painter's Tape (optional)
  • Exacto knife or painters tool
  • Abbrassive scrubber
  • Cloth or paper towel

2. Remove existing Caulk

Before applying the new caulk, you must remove the old application. If your old caulk is silicone you'll need to be extra careful to get every little bit out as it is tougher and will prevent new caulking from sticking properly. To remove caulk you can use an Exacto knife or painter's tool. Scour the edges of the old caulking, and then once separated, pull away at it to remove the caulk from the surface. Be careful not to scratch up your tub in the process!

3. Clean and Scrub

After removing the main chunk of caulking, there may still be some residue leftover. To remove this, use a dry, non-abrasive pad to scour the entire caulking surface. If removing silicone, you can also apply mineral spirits to your pad to make finishing the job easier. Wipe it down afterwards with a damp rag to remove the remaining dust. At this time you can also apply a bleach cleaner and use a rag to scrub away and mold that has built up. Dry with another rag or paper towel.

4. Tape (optional)

While freehanding is a popular method, using painter's tape is an easier method for beginners. Lay parallel strips of painter's tape about a half-inch apart on the surfaces you want to caulk. The open area will be the guide for your caulk, so it needs to be perfectly straight. Double-check that your measurements are correct and you are certain you are ready before moving on to the next step.

5. Caulk

Keep the nozzle equidistant between the two surfaces you want to caulk, so it does not come out lopsided. Apply steady pressure to the trigger, and smoothly move your nozzle down the entire length of the surface . You want to keep the gun moving at a consistent speed so the caulk does not thin out, or pile up. It needs to be a perfectly even stream the whole way down.

6. Smooth

When the caulk has been applied, it’s time to smooth things out. Take a damp cloth or paper towel and press a small area of the material gently into the caulking line with your finger (you can also use your bare finger if you don't mind the mess). In one continuous motion, drag your finger down the length of the seam to create a nice smooth surface. If you used tape, you can now remove it carefully, ensuring it does not touch any fresh caulk. Then go over the line one more time to remove any of the little bumps or edges left by the tape.
