Grind & Seal Concrete

Natural Concrete Finish

Grind & Seal Flooring

Grind and seal flooring is the industry term for concrete which has a clear coating system installed onto a concrete floor. Grind and seal concrete systems finish your floors so their striking, natural-look can shine through. Unlike other flooring that are applied atop a subfloor, concrete is the substrate itself.

That means whether you’re starting from scratch or you’ve pulled up an old floor for a renovation, your concrete is the foundation of the room. Thus, it needs the utmost care in final sealing to ensure it can withstand wear and tear for years to come.

Preparing the Concrete & Sealant Application

The process of concrete resurfacing is simple and fast, yet requires precision tools to obtain a pristine profile.

  • Diamond Grinding: The concrete surface is first ground down using specialized diamond-abrasive machinery to open up the pores.
  • Surface Deep-Cleaning: Once ground, the surface is thoroughly vacuumed, cleaned, and allowed to dry completely.
  • High-Performance Sealant: A clear seal coat is applied. The concrete sealant may be solvent polymer-based, water-based, or a reacting polymer that cures when two components are mixed together.

It is a highly suitable floor option in a variety of industrial and commercial spaces such as warehouses, manufacturing plants, retail, animal care facilities, and food service establishments.

Grind & Seal vs. Grind & Polish

Although this process is commonly referred to as "polished concrete," there is a slight technical difference between "grind and seal" and "grind and polish."

Grind & Polish: Hardened with a liquid chemical densifier and refined to a much higher level to create a natural, glass-like shine from the concrete itself. The densifier reacts with the cement to harden the top layers. It’s then sealed with a polish guard sealer to avoid any water, bacteria, or stains. Grind and polish systems tend to be more expensive but slightly more durable.

Grind & Seal: Provides a clear protective barrier on top of the concrete, offering excellent chemical and spill resistance at a lower price point, with gloss or matte options.

Aggregate Exposure Levels

One of the key benefits of floor resurfacing over other concrete processes is that this type of grinding works with any granite exposure level. The exposure level is the amount of the concrete’s rocks and stones that are exposed.

  • Zero Exposure: Takes off only the top cream layer for coating. This is the cost-effective look you might see in a warehouse or residential garage.
  • Partial Exposure: Takes off a deeper layer from the surface, showing sand and tiny aggregates. Flat and polished.
  • Full Exposure: Grinds away several millimeters so a maximum number of rocks and stones are exposed, creating a gorgeous terrazzo-like look.

Benefits of Grind & Seal Concrete Flooring

Industrial performance meets custom design. Protect your concrete against moisture penetration.

High Abrasion Resistance

Makes the concrete highly resistant to heavy foot traffic, machinery, and daily wear and tear. You can also add a slip-resistant grit/beading to enhance traction.

Non-Porous & Hygienic

Sealing renders the concrete non-porous, meaning it won’t harbor bacteria, mold, or stain easily. Makes the floor low maintenance and much easier to clean.

Moisture Protection

If concrete flooring is not properly finished and sealed, it will be very susceptible to penetration by moisture, which can ruin subfloors. Sealant guarantees full waterproofing.

Unique Aesthetic Options

Clear seals are available in both matte or glossy sheens, creating a unique and modern architectural look tailored specifically to the room's design.
