If you’re in the market for caulk, you probably have a few questions. What’s the difference between the two best types of caulk? Which one is right for your needs? And, of course, which one is the best value?

We’ve got the answers to all of those questions and more. In this head-to-head review, we’re going to pit the two best types of caulk against each other: silicone and acrylic. We’ll compare and contrast the two, so you can make the best decision for your needs.

Let’s get started.

Silicone vs. Acrylic Caulk: An Overview

If you’re not familiar with the different types of caulk, don’t worry. We’ll give you a quick overview before we get into the nitty-gritty of our comparison.

Silicone caulk is, as the name suggests, made from silicone. It’s a type of rubber that’s flexible and waterproof. That makes it ideal for areas that need to be sealed against water, like around a bathtub or shower.

Acrylic caulk is also waterproof, but it’s not as flexible as silicone. That makes it a good choice for areas that don’t need as much give, like around windows.

Now that you know the basics, let’s compare silicone and acrylic caulk in more detail.

Silicone vs. Acrylic Caulk: The Differences

There are a few key differences between silicone and acrylic caulk that you should know about before you make your purchase. Here are the most important ones.

1. Flexibility

As we mentioned, silicone caulk is more flexible than acrylic caulk. That makes it a better choice for areas that move, like around a shower door. Acrylic caulk is more likely to crack in those areas.

2. Adhesion

Adhesion is how well the caulk sticks to the surface you’re using it on. Silicone caulk has good adhesion, but it’s not as strong as acrylic caulk. That means it’s not the best choice for areas that need to withstand a lot of force, like around a sink.

3. Paintability

If you’re planning on painting over your caulk, silicone is the better choice. It’s easier to paint over than acrylic caulk.

4. Cost

Silicone caulk is usually more expensive than acrylic caulk. That’s something to keep in mind if cost is a factor in your decision.

5. Cure Time

Cure time is how long it takes for the caulk to dry and set. Silicone caulk has a longer cure time than acrylic caulk. That means you’ll have to wait longer before you can use the area you’ve sealed.

Now that you know the key differences between silicone and acrylic caulk, let’s compare them in more detail.
