Is it normal for caulk to crack?

You might notice some cracks in your caulk and wonder, “is this normal?”

The answer is…maybe. It all depends on the type of caulk you’re using.

There are two main types of caulk: silicone and latex. Each has its own benefits and drawbacks.

Let’s take a closer look.

Silicone Caulk

Silicone caulk is immensely popular because it’s waterproof and flexible, making it ideal for use in bathrooms and kitchens.

However, those same qualities can also make it more likely to crack over time.

As silicone ages, it tends to become brittle and lose its elasticity. This can cause it to crack under stress, even if that stress is just the weight of the caulk itself.

Silicone caulk can also be difficult to remove when it needs to be replaced, so keep that in mind if you decide to go this route.

Latex Caulk

Latex caulk is more affordable than silicone and easier to work with, but it doesn’t have the same longevity as silicone.

Latex caulk will eventually shrink and pull away from surfaces, which can cause cracks.

It’s also not as resistant to heat and cold as silicone, so it might not be the best choice for an exterior application.

So Is It Normal For Caulk To Crack?

There’s no definitive answer to whether or not cracked caulk is normal.

It all depends on the type of caulk you’re using and where you’re using it.

Silicone caulk, used primarily in bathrooms and kitchens for it’s waterproof nature, is more likely to crack.

Latex caulk is more affordable but doesn’t last as long and will eventually shrink and pull away from surfaces, which can cause cracks.

So yes, caulk can and does crack depending on the situation.
