Caulk for Drywall Cracks Buyer’s Guide:

Caulk for Drywall Cracks Buying Guide

There are several types of caulk depending on the job you’re going to do in the bathroom or kitchen. Choosing the right caulk is important to get the job done efficiently. However, you don’t need to get confused because we’ve covered everything in the guide.

Two Major Types of Gap Fillers

There’re two types of gap fillers; caulks and sealants. They both are great to get the filling done efficiently and vanish all cracks. However, there’re some key differences between them both. Let’s find them out now.

Elasticity & Rigidity

It’s a major difference between caulk and a sealant. Caulks get rigid when they are dry. And we use them in areas where we don’t want any expansion or contraction. On the other hand, sealants are made of a flexible material like silicone. The silicone makes them ideal for areas prone to expansion and contraction. They’re elastic, unlike the caulks.

CaulksSealants

You can use acrylic caulks as paint and use water to clean the smears. They’re not a good fit for temperature swings because of the limited elasticity. You can paint caulks because of their rigidity after they dry. And they’re suitable for non-fluctuating temperatures.

The silicone sealants help you keep a watertight seal even in the areas for substantial temperature swings. They aren’t paintable like the caulks. Sealants are flexible, not paintable, and great for fluctuating temperatures.

Our Recommendation

We recommend going for water-based caulks in temperatures above 40 degrees Fahrenheit. It’s best suited for dry weather. And they’re easy to work with. All you need is to clean the smears, apply the caulk, and drip it with water.

Choose the Right Type of Caulks

Honestly, there are tons of types of caulks available in the market. But let’s not just get confused and make it simple. We’ll discuss three major types of caulks. Let’s get geared.

Silicone Caulk

Applying Silicone Drywall Caulk

The silicone caulk must be the most popular type of caulk to be used in our homes. Why? It’s because the silicone caulk is perfect for areas prone to an exorbitant amount of water, like a bathroom and kitchen. You can use it on a variety of non-porous surfaces.

The silicone caulk remains flexible even after drying to avoid any cracking in the future. It’s waterproof, with high resistance to mold. Once it’s dried, you can clean it with water seamlessly. And it’s available in a range of colors.

The silicone caulk requires the use of a solvent for cleaning. Using it is more challenging than applying the acrylic latex caulk. Also, you cannot paint it because you cannot get it out of fabric even if you use a solvent.

It’s a combination of Butyl Rubber caulk and Acrylic Latex caulk. Let’s discuss them now.

Butyl Rubber Caulk

If you are a DIY-dude, you must not be familiar with Butyl Rubber caulk. Or are you? It has some special uses and is not a good fit for drywall cracks. We’re enlisting it here because of the educational purpose only.

The major use of the butyl rubber caulk is filling cracks in concrete and brick. And you can also use it to seal metal surfaces. You don’t have a variety of colors to choose from, but you can paint it to match the surrounding surfaces.

Acrylic Latex Caulk

You can use the acrylic latex caulk as a sealant around windows and doors. You can either use it indoors or outdoors. We don’t recommend using it in the bathroom and kitchen, though. It’s available in a range of colors. And you can paint it to blend with adjoining surfaces.

Applying it on any surface is easier than applying silicone or butyl rubber caulks. Cleaning is also easy with soap and water only.

Things to Consider While Buying Caulk

There are a few things you need to consider before buying a caulk for drywall cracks.

MaterialTemperatureMoistureLocationPaintability

Read descriptions before buying any caulk because some caulk stick with certain materials better than others.

You must always see if a caulk is good for the temperature it’s going to bear. Some caulks may handle extreme temperature changes while some can’t.

Consider the moisture of the area where you’ll apply the caulk. For example, some caulks can easily handle places where water stays longer than usual while come cannot.

Caulks are location-specific, which means you should not apply wall caulk instead of a bathroom caulk. It’s that simple.

Before you buy a caulk, determine if it’s paintable. And decide if you want some paint after it gets dried.
