What Causes Cracks in a Bathtub?

Bathtubs are one of the most commonly used fixtures in any home, so it’s no wonder they often suffer wear and tear over time. Cracks are one of the most common problems that can occur, and they can happen for various reasons. The most common cause of cracks is thermal expansion.

This happens when the tub is exposed to drastic changes in temperature, making the material expand and contract. Sometimes, this can result in small cracks on the tub’s surface. Over time, these cracks can become bigger as they are subjected to more wear and tear.

One of the most common causes of cracks is impact damage. This can happen if something heavy is dropped into the tub, or if it’s hit by a hard object. Impact damage can also occur if the tub is installed on an uneven surface. If the tub isn’t properly supported, it can shift and settle over time, which can cause cracks to form.

Regardless of the cause, it’s important to repair any cracks in your bathtub as soon as possible. Left unrepaired, these cracks can lead to larger problems, such as leaks and water damage.

Why It’s Important to Fix Cracks in A Bathtub?

Cracks in bathtubs are not only unsightly, but they can also lead to major problems if left unrepaired. Water can seep through cracks and cause extensive damage to the surrounding area, including mold and mildew growth.

In addition, cracks can provide a hiding place for bacteria and other harmful organisms. By taking the time to repair cracks as soon as they appear, you can help safeguard your health and extend the life of your bathtub.

How to Fix Cracks in A Bathtub Step-by-Step Guide

Step 1: Identify the Damage

The first step is to look at the tub and identify the damage’s severity. If there are only small cracks, then you may be able to repair them relatively easily. However, if the cracks are large or there is significant damage, you will need to replace the tub.

Step 2: Clean the Tub

Once you have determined the extent of the damage, it is time to clean the tub. This will help you remove any dirt, soap scum, or other debris that may be present. To begin, use a soft cloth and warm water to wipe down the tub’s surface. If there are any stubborn spots, you can use a mild cleaning agent and a non-abrasive scrubber.

Step 3: Dry the Tub

After cleaning the tub, it is important to dry it completely. Any present moisture can make the cracks worse or cause new ones to form. So instead, use a soft towel to dry the tub’s surface, taking care to dry any cracks. Then, follow up by wiping the entire surface with a clean and dry cloth.

Step 4: Apply Epoxy

The next step is to apply epoxy to the cracks. This will help to fill them in and prevent further damage. Begin by mixing the epoxy according to the manufacturer’s instructions. Once mixed, use a putty knife or other similar tool to apply it to the cracks. Be sure to smooth it out so that it is level with the tub’s surface.

Step 5: Let the Epoxy Dry

Once you have applied the epoxy, it is important to let it dry completely. This can take several hours or even a day, so be patient. Once it is dry, you can use the tub as normal.

Step 6: Sand the Area

If the epoxy is not completely smooth, you can sand the area to even it out. Begin by using medium-grit sandpaper to sand the surface lightly. If there are any rough spots, you can use finer-grit sandpaper. Once you are finished, wipe down the area with a damp cloth to remove dust.

Step 7: Apply a Sealant

You can apply a clear sealant to protect the epoxy and help it last longer. Begin by applying the sealant to a small area to test it first. If it goes on smoothly, you can continue. If not, you may need to try a different brand. Once you have applied the sealant, let it dry completely before using the tub.

What Kind of Caulking is Best for a Bathtub?

There are a few things to consider when selecting caulk for a bathtub. First, think about the material of the tub. If it is made of porcelain, enamel, or another smooth surface, you will want to use a silicone-based caulk. On the other hand, you can use silicone or latex caulk if the tub is made of fiberglass or another textured surface.

You will also want to consider the color of the caulk. While white is the most popular color, it can also be more difficult to match your bathroom’s décor. Clear caulk is a good option if you want something that will blend in. Once you have decided on the caulk type, clean and dry the area around the tub before applying the caulk, this will help ensure a tight seal.
