Tips for Selecting Caulk for Your Commercial Painting Project

No commercial painting project is truly complete without caulk. This synthetic substance seals various vulnerable parts of a building, such as gaps between surfaces, seams between pipes and fixtures, and cracks in concrete and other materials. However, not all caulk is created equal. There are in fact several types of caulk available, made from different materials and optimized for specific purposes. Let’s go over these different kinds of caulk and their uses to help you select the right caulk for your commercial painting project.

What to Know About Commercial Caulking

What Types of Caulk are There?

When it comes to choosing commercial caulking, your options include, but are not limited to:

  • Latex caulk

  • Acrylic latex caulk (Painters caulk)

  • Vinyl latex caulk

  • Silicone caulk

  • Latex silicone/Siliconized latex caulk

  • Butyl rubber sealants

  • Polyurethane foam

  • Fireproof caulk (Refractory caulk)

  • Asphalt caulk

  • Modified silicone polymers

In some cases, the name of the caulk gives away its primary function. Mostly, though, these products only give away the caulk’s composition and not much else. In order to choose the right caulk for your property, you need to know more about what each product is good for.

Choosing the Right Kind of Caulk for Your Commercial Painting Projects

As you sift through the several commercial caulking products out there, it helps to focus on some key factors. Let’s discuss what you might look for in a given caulk product and which types of caulk fit the bill.


Obviously, you want your caulk to last, no matter what you’re using it for in particular.  Of course, there is more to consider than just durability. Even the strongest all-around caulk products may have their weaknesses when it comes to extreme temperatures, moisture, etc.

Defense Against Water Intrusion

While all caulks are designed to seal, some are more specifically used as a waterproof sealer. If your commercial painting project includes areas that are meant to or are at risk of contacting water on a regular basis, polymer, or siliconized acrylic caulks are your best bet.

Air Insulation

Well-insulated buildings can save thousands on energy costs each year. So, if you’re looking to become more energy-efficient and keep the outside world from intruding on your property, many caulk products will do, including polymer, butyl rubber, acrylic latex, and silicone polymer caulk.


Fire-resistant caulk products are useful in any building, but especially in those that handle corrosive materials, use a lot of electricity and gas, and/or produce plenty of heat. Commercial painters can apply fireproof (intumescent) coatings as one measure against the spread of flames, but adding fireproof (refractory) caulking helps seal the deal when it comes to safety.

Plumbing Protection

When choosing caulk to reinforce or repair your pipes, go for a pure silicone product. 100% silicone caulk can withstand the wear and tear of water and can be applied to just about any surface. So, no matter what your pipes are made of, this caulk will work. 

Masonry Maintenance

Painting brick, concrete, and other porous surfaces can be challenging. Don’t let that hard work go to waste by inserting the wrong type of caulk for the job.  The best suited caulk for this application is a 100% solids two component, heavy duty polyurea joint filler.

Reliable Interior Repairs

When it comes to interior maintenance and repairs after a commercial painting project, acrylic latex caulk, also known as painter’s caulk, is the winner. This type of caulk comes in various colors, too, giving it the aesthetic edge other caulk products often lack. It’s also highly washable and useful for exterior work as well.
