For years, Perfect Concrete Care have been getting this question from clients, so we decided to create this blog post just to clear the air on the difference. A concrete grind and seal job are usually carried out with just a few passes on the surface, and then a concrete sealer is applied to protect the finish. Polished Concrete is a more detailed process which usually includes 3-4 passes with metal bonded diamond shoes followed by the application of a densifier and hardener. It is then followed by 4-6 passes of resin bonded diamond shoes and finally the application of a sealer to protect the finish.
Perfect Concrete Care usually carries out grind and seal for large car parks, industrial units, and factories, but more recently we have seen an increasing trend for the demand of grind and seal finishes in commercial locations, retail centres, and even offices, as it has become a very popular design trend. However, concrete polishing is usually for more high-end locations like bank lobbies, hotel lobbies or car showrooms.
Grinding & Sealing
Grind and seal is the name given to the process of concrete grinding a slab and applying a sealing agent to seal and protect the floor surface. A typical grind & seal project would consist of 3-4 passes with metal bonded diamond shoes. Then, the surface would be thoroughly cleaned with a Polyvac to ensure the surface is completely dust free. Once the surface is ready we then apply the sealing agent, at Perfect Concrete Care we use ViroSeal as it is a GreenStar approved penetrating sealer.
Benefits of Grinding & Sealing
There are many advantages of Grinding and Sealing a floor surface:
- Cost Effective
- Strengthening the floor surface
- Provide excellent penetration
- Greater abrasion resistance
- Elimination of dusting from efflorescence
- Stain resistance
- Adds slip resistance
- Improved condition of old floors
- Reduced tire wear
- Less maintenance
- Customisable system
- Improve GreenStar Rating
Polished concrete is achieved through applying a series of mechanical grinding and honing steps using equipment, chemical hardeners and sealers to create a surface that is aesthetically pleasing, durable and easily maintained. Depending on the desired effect and finish of the floor surface a polishing project usually consists of up to 3 passes of metal bonded diamond shoes, conjunctionally with a Densifier & Hardner. This is then usually followed by 4-6 passes of resin bonded diamonds and then the application of a sealer. Polished floors take significantly more time and effort to produce a high-end finish but the results speak for themselves.

Concrete Polishing is more suited for a more high-end result. Usually, you would see Polished Concrete floors in Bank Lobbies, Hotel Lobbies or Law Firms. When you get a good Polished Concrete Contractor like Perfect Concrete Care it can really create a “WOW” factor.

Maintenance of Polished Concrete
Unlike a grind and seal project, polished concrete requires more maintenance to preserve that super reflective surface. Usually, it requires an application of C2 Cleaners designed for maintenance, that is concrete neutral to ensure your floors stay shiny for longer. Perfect Concrete Care offer maintenance services for the Polished concrete floors we install.
