What is Concrete Grinding and Sealing

We are always in a look out to have the perfect and new applications we can add into our homes, may it be the new process of crown moulding or the beam structures. Sometimes we often forget that the floor we always walk on can complete the house over all look. We are so focused on the walls, support and everything and completely ignore other factor that makes a difference in the final output. But all through the beauty we should always think of the durability. Being aesthetically appealing and durable at the same time is a win-win situation for anyone. And that’s what concrete grinding and sealing provide.


Concrete grinding and sealing is a term to describe the system of applying a protective and transparent coating to concrete floors. It is also a method of polishing and concrete resurfacing. The top layer of concrete is grinded back to show as little or as much stone as the client desires. This process includes grinding and then sealing the floors. The eradication of any scratches or impurities in the surface layer of any concrete is what grinding do. It is achieved by using high power concrete grinders that can quickly and efficiently saturate the surface of the concrete with scratches. You can choose to use finer diamonds to remove visible scratching. Then get a flat surface ready for coating once the right level of stone exposure has been achieved. Lastly, the floor is finished with a protective sealer. This sealer can be a matte, semi-gloss or high gloss.


The sealing part where a topical sealer is put on top to protect the concrete is done after the grinding. These sealing coats are mainly made of urethane, epoxy or acrylic. Although the process points out to ‘polished concrete’, there is still a slight difference between ‘grind and seal’ and ‘grind and polish’. Grind and polish are hardened with a densifier and are refined to a much higher level to create the shine. With proper sealing, there is almost no space left to allow air through the concrete, and the sealant plays a crucial role in binding the concrete.

The first step in concrete grinding and sealing is to grind away any existing coatings or impurities such as grease and dirt. And begin to smooth the surface of the floor. Patched and filled at this time are any larger holes, divots and expansion joints. Grinding also allows for adhesion between your concrete and the concrete stain and/or sealer.


Staining or colouring your concrete is optional. This allows you to ensure that your floors appearance will match the theme or colour-scheme of the room.


A sealer is applied to protect and enhance the beauty and durability of your new concrete floor. Proper sealers will resist stains from most industrial chemicals. Some of the quality of the sealers can even offer a lifetime warranty against peeling and yellowing.

The proper seal coating delivers a hard finish that holds up exceptionally well, even in high traffic areas.


The floor undergoes evaluation and process and passes the requirements for slip resistance; grip can be further increased with the inclusion of grip enhancing additives, if desired.
