Commercial Concrete Sealing Companies FAQs


Commercial concrete sealing companies provide peace of mind for your building’s concrete structures knowing that our penetrating sealant keeps out moisture by filling in the tiny pores found naturally in concrete.

Discover our answers to frequently asked questions about commercial concrete sealing companies.

We offer a 25-year warranty on concrete sealing jobs thanks to our penetrating sealant that keeps out moisture by filling in the tiny pores found naturally in concrete.

The average cost of a commercial concrete sealing job varies based on the size and scope of the project. One thing to keep in mind is that our team doesn’t just lay down a topcoat. We offer a penetrating sealant that keeps out moisture, which prevents hairline cracks from becoming larger cracks years in the future.

You’ll see some figures of $2 per square foot for commercial concrete sealing companies, but in reality it depends on the size and scope of the job.

Yes and no. Penetrating concrete sealants are designed to prevent moisture from intruding into the concrete, which can cause hairline fractures and cracks over time. It depends on how the color was applied to your concrete. If the concrete has just a topcoat of color, the benefit of penetrating sealant might not be noticeable. If the color is throughout the concrete, commercial concrete sealing can help your concrete structure maintain its steadfastness by keeping moisture out and having minimal cracks.

Penetrating commercial concrete sealants are made of silanes, siloxanes, and/or siliconates. Silanes are the most prominent and best substances to use as penetrating sealants.

Silanes penetrate into the concrete substrate and react chemically with the calcium hydroxide in the concrete. When this occurs, the commercial concrete sealant creates a water-repellant resin within the pores of the concrete. 

Your concrete must have an alkaline pH and contain enough calcium hydroxide for silanes to work. Typical concrete contains up to 15 percent calcium hydroxide by volume, which is plenty for our penetrating sealant to do its job. Silanes are best for high-performance concrete.

Siloxanes are like silanes and work for highly porous concrete while penetrating the surface.

Yes, commercial concrete sealers made of silane repel water, moisture, salts, dirt, and other impurities that touch the surface. They also resist mold, mildew, and fungi because they repel moisture. Penetrating silanes protect against freeze-thaw (which can form cracks) as well as efflorescence, which is the appearance of white salt deposits on the surface of the concrete.

Most commercial concrete has rebar inside of it, which reinforces the concrete structures to make them sturdier. When moisture penetrates concrete, it can gradually cause rebar and steel to rust and corrode. Weakened rebar can cause damage to the structure over time. If a crack forms all the way to the rebar, corroding can accelerate due to deicing salts, acid rain, salty air in marine environments, and saltwater near the ocean.

Your concrete surfaces must cure for a minimum of 28 days after the initial pour before we can seal your commercial concrete. The sooner you take care of it, the better.

The best commercial concrete sealing companies will thoroughly clean the concrete surface as much as possible before applying penetrating concrete sealant. Cleaning the surface will help the sealant absorb as much as possible into the surface, leaving no area untouched.

Seal Smart’s permanent commercial concrete sealing comes with a 25-year warranty. It can protect your deck from moisture intrusions, which can lead to cracks and chips.
