Take the Guesswork Out of Choosing a Caulk

During a bathroom renovation project several years ago, I headed to the store for caulking to use around the sink. As I stood in front of the aisle, trying to make sense out of the various types of caulk, I scratched my head in confusion. What had I gotten myself into? I hadn't a clue what to buy. Who knew there would be so much involved with choosing a caulk? I left the store with nothing that day, except the desire to educate myself on a subject I obviously knew nothing about.

Since that day I've learned a lot, including that I was not alone in my confusion of choosing a caulk. Many people I spoke with, including men, find themselves confused with the different types of caulk and their applications. Today, I'll try to help take the guesswork out of choosing a caulk, and explain the pros and cons of each.

What's caulking for?

Caulking is used to form a flexible seal that helps waterproof various areas of the home. It is applied between small cracks and gaps in many locations inside the home, including:

- Bathtubs

- Sinks

- Faucets

- Plumbing fixtures

- Showers

- Baseboards

- Molding

- Cabinets

- Countertops

- Window panes

- Door frames

Common types of caulk:

There are many different types of caulk. Some will be less expensive than others, some will be more durable, some dry faster, and some are easier to use than others. Choosing a caulk that is best for your job is important. Here are some of the most common types of caulk:

Latex caulk - Latex caulk is probably the most commonly used type of caulking. It's affordable, easy to use, dries in about 30 minutes, and works well for general caulking purposes. This is a water-based caulk, so it is easy smooth out, simple to clean, and works on virtually any surface. The only real downfall to using this caulking is it will need replaced every few years, as it is not as durable as more expensive types of caulk. Average lifespan is 7 years.

Acrylic latex caulk - Acrylic latex caulk is slightly more expensive than regular latex, but it is also a bit more durable and longer lasting. It is very simple to use and apply, dries in about 30 minutes, and can be used on virtually any surface. It is also fairly easy to remove, when the time comes to do so. It can be painted over, if desired, and is commonly used by painters and contractors in residential home for its versatile application and affordable price. Average lifespan is 5 - 10 years.

Silicone caulk - Although silicone caulk does a fabulous job at waterproofing, it can be more difficult to work with than its latex counterparts. It is more difficult to control when applying, makes a bit of a mess, and releases stronger fumes than a latex caulk. With that said, silicone caulk does have an amazing stretching ability, and can easily cover a larger crack or gap of up to a 1" space. It cannot be painted over, and takes roughly one hour to dry. Average life space 20+ years.

Polyurethane caulk - Many professionals refer to polyurethane caulk as the ultimate sealant. It is extremely durable and long-lasting, can cover large cracks and gaps up to 1", and has a phenomenal stretching ability. For non-professionals, however, it can be a nightmare to work with. Polyurethane caulk has a very sticky consistency, similar to putty, and creates a heck of a mess. In can't be cleaned with regular water, and removing it from surfaces and tools will require the use of mineral spirits. It does, however, adhere to virtually any surface and is the ultimate waterproofing sealant. It has the longest dry time of any caulks we've listed, taking roughly 24 hours to dry. Average lifespan 20+ years.

A quick note about dry time - Above, we've listed an approximate dry time for each of the common types of caulk. In addition to the dry time, the curing time needs to be taken into consideration when choosing a caulk. Because each product is different, consult the package directions for precise curing information.
