How to Caulk Your Bathtub

Has the old bathtub caulking started to peel, leak or look gross? If yes, you are probably due to caulk your bathtub. This process is much easier than you might think! Read on to learn how to caulk.

How to Caulk Your Bathtub

Understanding the Why Before the How

Before diving into the “how,” let’s briefly touch upon the “why.” Caulk, primarily a silicone or latex-based sealant, is used to fill cracks and gaps in your bathroom, especially around your bathtub, to create a waterproof barrier. This barrier is crucial in preventing mould and mildew growth, safeguarding the structural integrity of your bathroom, and maintaining a clean and appealing aesthetic.

Choosing the Right Caulk for Your Bathtub

Beholding a seamlessly caulked bathtub, one might not realize the importance of the decisions made before even laying the first bead of caulk. That’s right, a successful caulking job begins with choosing the right type of caulk. Let’s delve into the nuances of this initial and important part of your caulking journey.

Silicone vs. Latex: The Best Caulk for Bathtub

Caulk primarily comes in two distinct types: silicone and latex. So, which should you choose for your bathtub? It largely depends on your specific needs and circumstances.

Silicone caulk is highly durable, remains flexible, is exceptionally resistant to mould, and offers superior water resistance. This makes it a popular choice for high-moisture environments, such as your bathroom. Although silicone tends to be more challenging to apply smoothly and cannot be easily painted, its longevity in damp conditions makes it an ideal choice for your bathtub.

On the other hand, latex caulk (sometimes labelled as “acrylic” or “vinyl”) is easier to apply, smooths out beautifully, can be painted to match your decor, and is quite easy to clean up. It may not offer the same level of water resistance or flexibility as silicone, but in less demanding moisture conditions, it can still be a reliable choice. If aesthetics are your priority and you’re confident in your ability to maintain your bathtub well, latex can work wonders.

Understanding Caulk's Lifespan and Durability

A significant factor to consider when choosing your caulk is its lifespan and durability. Most types of caulk, after being correctly applied and allowed to cure, have a life expectancy of about five years. However, this can vary based on factors such as the level of moisture exposure, fluctuations in temperature, and the quality of the initial application.

Bathtub silicone caulk often stands out in terms of lifespan, offering up to 20 years of service. Latex, while easier to work with, may require a bit more maintenance and replacement every few years.

Colour Match: Selecting the Perfect Caulk Shade

Last, but certainly not least, let’s consider colour. Caulk may seem trivial, but it plays a substantial role in the overall aesthetics of your bathroom. Most people opt for white or clear caulk for a seamless look, but don’t be afraid to explore other options.

Caulk comes in various colours, and some brands even offer custom colour matching. Consider the colour of your tiles, your bathtub, and your bathroom palette when choosing your caulk colour. This might be your opportunity to add a subtle touch of creativity to your bathroom space. Just remember, function is equally important, so ensure your beautifully coloured caulk also delivers on performance.

How to Caulk a Bathtub: Step-by-Step Guide

1. Remove Old Caulk From Bathtub

  • Using a utility knife or a caulk remover, scrape off the existing caulk around the bathtub. Be careful not to scratch the bathtub or wall tiles.
  • Clean around the area with white vinegar and a sponge to get rid of any mould or leftover caulk.
  • Dry the area with a rag and let it dry.

2. Prepare Before Caulking Your Bathtub

  • Use painter’s tape for improved accuracy and to avoid a mess – tape along one piece above the part you want to caulk and then one piece beneath it. This is so when you are caulking your bathtub, if you get some of it on the tape, it can be easily cleaned up.
  • Try to place the tape approximately 1/8” on either side of the spot you want to caulk.

3. Caulk your Bathtub

  • The opening tip of the caulk should be the same size as the area between the painter’s tapes.
  • Trim the caulk at about a 45-degree angle.
  • Load the caulk gun with the caulk and use smooth, steady pressure on the trigger while you move it along the seam of the tub.
  • Try not to move too slowly, use a gradual, medium-speed pace while caulking a tub.
  • After the caulk has been applied, run your finger along the joint to smooth it out and get rid of the remaining caulk. Some people use an ice cube instead of their finger, and this method is perfectly fine as well.
  • Wait 20-24 hours to let dry.

Embracing the Process

While caulking your bathtub may appear challenging initially, embracing the process with patience and attention to detail can transform it into a manageable, even enjoyable task. Remember, the key to mastery is practice and patience.

You’ve now taken an important step in maintaining the beauty and integrity of your bathroom. Feel confident in your ability to preserve your home while also enhancing its appearance. Should you encounter any obstacles along the way, know that solutions are within reach and you’re more than capable of overcoming them.

Caulking your bathtub is not just a task; it’s an investment in your home and a testament to your ability to handle the various challenges homeownership presents. Take pride in the work you’ve done—your beautifully caulked bathtub is a reflection of your dedication to maintaining a clean, safe, and welcoming home.
