It Usually Starts Small
A lot of homeowners notice a small crack, chip, or damaged area in their finish and assume it's purely cosmetic. Since the damage may only be a few inches long or barely noticeable, it's easy to put off repairing it.
The problem is that small cracks rarely stay small.
What starts as a minor imperfection can eventually turn into a much larger issue if water is allowed to find its way underneath the surface.
Water Is the Real Problem
The crack itself isn't always what causes the biggest issue. The real concern is what happens once water begins seeping underneath the finish.
Every time the tub is used, moisture can work its way through damaged areas and become trapped beneath the coating. Since the water cannot easily evaporate, it sits underneath the finish and slowly begins causing problems.
In many cases, homeowners won't even realize this is happening until visible damage starts appearing.
Bubbling and Lifting Can Follow
Once water becomes trapped beneath the finish, one of the first signs of trouble is often bubbling.
Small blisters may begin appearing on the surface as moisture pushes upward from underneath. Over time, these bubbles can grow larger or spread to surrounding areas.
Eventually, the finish may begin lifting away from the tub entirely. What started as a small crack can turn into a repair that affects a much larger portion of the surface.
Cracks Can Continue to Spread
Another issue is that cracks often grow with normal use.
Bathtubs can expand and contract slightly with temperature changes and regular use. As water enters the damaged area, the crack can continue to widen, allowing even more moisture underneath the finish.
The longer the problem is ignored, the greater the chance that additional repairs will be needed later.
Early Repairs Are Usually Simpler
The good news is that addressing small cracks early is often much easier than waiting until widespread damage develops.
Repairing a small damaged area can help prevent water intrusion before bubbling, lifting, peeling, or staining occurs. It also helps preserve the surrounding finish and reduces the likelihood of needing a larger repair down the road.
Don't Wait Until the Damage Gets Worse
One of the most common causes of bubbling and lifting that we see is water finding its way underneath the finish through an untreated crack or damaged area.
If you notice a crack, chip, or spot where the finish has been compromised, it's always best to address it sooner rather than later. Taking care of a small problem today can help prevent a much larger repair tomorrow.
