Commercial Concrete Sealing: Extend the Life of Your Investment

Commercial concrete sealing is an economical way to protect large concrete projects. Property improvements can be expensive and property managers want those improvements to last as long as possible and maintain the appearance of their properties.

The biggest reason to seal commercial concrete is to protect it from salt and other substances that will accelerate deterioration. Please visit The Benefits of Concrete Sealing for more information.

There are several freeze-thaw cycles a year in Michigan, which are extremely hard on concrete. Salt is necessary to melt ice and avoid liability issues in areas where customers, clients, and residents will be walking. However, salt accelerates the freeze-thaw cycles and promotes faster deterioration of concrete. Salt also attracts moisture out of the atmosphere and into the concrete. Water and salt will shorten the life of any concrete project.

Unsealed concrete needs to be replaced more often, which is substantially more expensive than commercial concrete sealing and maintenance.

If you are throwing salt, you are eating your concrete alive.

The Main Places for Commercial Concrete Sealing

The most common type of concrete sealer on non-decorative concrete is penetrating sealer. It soaks into the concrete and protects the structure of the concrete from freeze-thaw cycles. It can be applied 3-5 days after fresh concrete has been laid and dries within about an hour. There is very little disruption to the flow of traffic and should not slow down the operation of a business.

The most beneficial places to seal concrete on commercial properties are:

  • Driveways
  • Sidewalks
  • Entryways
  • Loading docks
  • Parking lots

Loading Docks

Loading docks are particularly susceptible to wear and tear. They are high traffic areas that take a lot of abuse and typically sustain a lot of salt. Not all of it washes down the trench drain and salt residue can build up, creating pitted concrete that gets eaten away. Sealing loading docks will keep them functioning better for longer.

Retail Entryways and Sidewalks

Pouring new concrete in front of business entryways and sidewalks can disrupt the flow of business for several days. Applying concrete sealer in front of doorways and on sidewalks will minimize the frequency of replacing concrete and sustain existing concrete for longer.

Oftentimes, the few inches of sidewalk closest to a building will appear much more pitted and worn down than the rest of the sidewalk. This happens when salt is applied to icy sidewalks and is then pushed toward the building by foot traffic and weather. The excess salt collects near the building which is typically under an overhang. Rain and snow will wash away a lot of the salt on sidewalks but they don’t always reach the salt that has built-up next to the building. The salt sits on top of the concrete, slowly eating it away and causing an uneven surface. When applied on a regular schedule, commercial concrete sealing can virtually eliminate this problem.

Sealing Stamped and Decorative Concrete

Many commercial properties also have high-dollar decorative and stamped concrete areas such as pool decks, entryways, and common areas. This type of concrete investment definitely requires concrete sealing. Acrylic sealer is used for this type of concrete, which creates a protective film on the top of the concrete. This sealer makes the color and design of the concrete pop and protects the surface. Read Sealing Stamped Concrete for more information.

Professionally Applied Concrete Sealer

The process of applying penetrating and acrylic concrete sealer is not difficult. Variations of these types of sealers are available at big box stores, however, the best formulas on the market for the best prices are only available to concrete sealer contractors. It is worth your time and money to have professionals seal your concrete for you.

As mentioned earlier, concrete sealer can be applied to new concrete within 3-5 days of curing. New concrete typically does not need to be cleaned or power washed prior to sealing. Simply sweep the new concrete to remove any leaves, dirt, and sticks.

Older concrete should be power washed first and allowed to dry completely before applying sealer. If the concrete is particularly dirty or has oil spills and other substances on it, a deeper clean may be necessary.
