HOW DO YOU CAULK A BATHTUB

How Do You Caulk a Bathtub?

Mold loves growing in humid environments, especially your bathroom. Even with great ventilation, mold can still find a way to take hold around your bathtub. If you see mold in the cracks around your tub, don’t ignore it. Unchecked mold can lead to respiratory problems and other illnesses. Gaps between your bathtub and shower and the wall are the perfect places for mold. As old caulk wears away, the gaps grow. If you noticed gaps and mold, it’s time to recaulk. 

Tools You Need for Caulking Your Bathtub 

Before you caulk your tub, you’ll need the right tools. Here’s a list you can use when prepping for the project. Make sure to have: 

  • A caulking gun
  • A tube of caulk – specifically for tubs 
  • Pair of rubber work gloves 
  • Razor scraper with single-edge razor blades 
  • A utility knife 
  • Denatured alcohol 
  • Paper towels 

How to Caulk Your Bathtub 

Removing the Old Caulk 

  • Remove the Old Caulk – Use your razor scraper to remove the old caulk. Simply scrape using the razor until the old caulk is removed. Plastic blades are better because metal can damage tubs made of plastic. Use quick, sharp strokes with the scraper, and be careful. 
  • Clean the Old Caulk Debris – Remove any leftover pieces. You can even use a shop vacuum to suck up any leftover pieces. 
  • Wipe it Down with Denatured Alcohol – This is the final step before applying the new caulk. It removes stray pieces and gives you a clean and smooth surface to work with. 

Adding the New Caulk 

  • Load Your Caulk Gun – First, make sure the caulk you’re using is formulated for the type of bathtub you have. Load the caulk gun. Cut the tip off at a 45-degree angle, then push the application gun through its nozzle to break the seal.  
  • Apply the New Caulk – Use painters tape to aid you with straight lines as you apply the caulk. Hold the caulking the gun at a 45-degree angle from the edging as you apply. 
  • Smooth the Caulk – The caulk will be applied as a long tube. Use a damp paper towel or rag and press it gently into the seam you’ve created with your finger. Run it along the caulk in a continuous line to create a clean look. 
  • Remove the Tape and Let Caulk Dry – Remove the tape, so it doesn’t get stuck as it dries. Don’t touch the caulk or use your tub for at least two days following the application.
