What Is Commercial Concrete Floor Sealing?

Commercial concrete floor sealers are resin-based, water-emulsion compounds we apply to unprotected concrete floors to protect the surfaces from corrosion, physical damage, and staining. 

Installation Process for Our Commercial Concrete Floor Sealing in Portland

We Clean the Concrete

Our team removes all debris and dirt from your floor with a thorough sweep, followed by a washdown to remove stains and spills. 

We Remove Old Sealer

We remove the old layer of sealant through mechanical or chemical means. Mechanical removal includes grinding, blasting, or sanding the sealer, while chemical removal typically uses Xylene to dissolve the sealant.  

We Apply the Sealant

First Coat. The first sealant coat acts like a primer to reinforce the concrete surface.

Second Coat. The second sealant coat provides color enhancement, gloss, and an even finish. 

We Allow for Drying

The final drying time depends on the type of concrete sealer. Acrylic sealers require 4-12 hours for proper drying. Polyurethane sealers take 24-48 hours. Epoxy sealers take the longest drying time at an average of seven days. 

Pros & Cons of Sealing a New Concrete Floor


Shields the floor against dust and moisture damage: Commercial concrete floor sealers protect floors against debris and water damage. The surface is seamless, strong, and moisture-proof.  

Increases concrete floor lifespan: Concrete floor sealants provide a protective barrier for the concrete surface, preventing it from deteriorating or spalling. Untreated concrete floors last an average of five years before they show signs of wear and tear, but sealed concrete floors can last up to twenty years or more. 

Enhances floor color: Sealing commercial concrete floors enhance existing colors, making them more eye-catching and adding instant aesthetic appeal to your commercial property. 


Can make floors slippery: Sealed concrete surfaces can be slippery when wet. For areas with high foot traffic, we recommend adding an abrasive compound in the sealer formulation to create a non-skid surface.  

Requires semi-regular replacement: Sealed concrete surfaces need resealing every few years, particularly in high-traffic areas, areas with high-weight loads, or areas that are regularly exposed to chemical spills such as garage floors or automotive shops. If you’re looking for a resealing schedule, we recommend an average of two years no matter what type of sealant you are using.  

Is better suited for older surfaces: Concrete sealers are only suitable for established concrete surfaces that are at least a month old. Sealers will not adhere properly to newly poured concrete slabs. If the unsealed concrete has not cured properly, sealers can also damage the structure of the slab.

Types of Commercial Concrete Floor Sealing in Portland, OR


Concrete floor sealing contractors recommend acrylic sealers for general protection from dirt and grime in both indoor and outdoor settings. Acrylic sealers form a thin layer of protection and are easy and quick to apply. 

While these sealers are cost-effective, they also wear more easily and require replacement much more quickly. Acrylic sealers have water-based and solvent-based formulations, so it is best to talk to concrete floor sealing companies like us to find the better option for you. 


Polyurethane sealers provide a long-lasting layer of protection for both interior and exterior applications. This type of sealer is particularly popular for exposed surfaces because it does not yellow when exposed to harsh weather conditions. 

Polyurethane sealers are versatile and can achieve a variety of gloss levels and tint intensities. Commonly used in areas with high foot traffic, they also provide good protection against chemical and abrasive damage. Some establishments need this product’s fast drying turnaround times, such as hospitals and shopping centers.


Epoxy sealers are best for interior applications where conditions require durable and long-term surface protection. These sealers come in a wide range of colors, tints, and drying times, making them suitable for a variety of conditions. 

Epoxy sealers can provide superior strength for commercial areas such as parking lots. They are ideal for high-end establishments that require a glossy and attractive finish on concrete floors, such as five-star hotel lobbies. 

Frequently Asked Questions (FAQs) on Commercial Concrete Floor Sealing

How many surfaces should I seal?

It depends on your needs, but we recommend sealing all concrete surfaces in places with high foot traffic or weight loads. 

Are there negative consequences to not sealing my concrete?

Having concrete surfaces unsealed leaves these surfaces weak and prone to cracking, chipping, and gouging. Unsealed concrete surfaces are porous; enabling moisture to seep into the surface; the resulting water damage can cause pitting and pocketing in the concrete matrix. 

How much does sealer cost?

Commercial concrete sealing typically costs around $0.06 to $0.38 per square foot. For a 500-square-foot commercial space, the cost for the sealer will range between $40 to $165 with five gallons of the compound. 

How will my sealed surface look?

A concrete floor sealer adds beauty and longevity to your concrete floors. Sealing enhances the attractiveness of a concrete floor through vibrant colors, a glossy and even finish, and a smooth surface. Sealing also preserves the decorative treatment by adding a protective barrier against abrasions and stains.

What is the lifespan of my sealer?

Acrylic concrete coatings need re-applying every one to three years, which means this type of sealer has the shortest lifespan.  Epoxy and polyurethane sealers can last anywhere from five to ten years, with a shorter lifespan for surfaces with high foot traffic.
