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.


Grinding and sealing concrete floor provide numerous benefits and will surely be worth the money you will invest in.


Fewer grinding steps are required to achieve your desired appearance and finish with the proper sealer. It also never needs to be buffed or burnished, which save you even more.


A sealed concrete floor has a natural beauty that few other floors can match.  Working with Advanced Flooring Systems will give you a stunning surface that lasts.


Our sealed concrete floors are much easier to keep clean than unsealed concrete. And even polished floors with an acrylic sealer, decreasing expenses by requiring fewer labour hours and a fraction of the chemicals you’re currently using to clean.


Unlike acrylic sealers, which do not hold up well to acid, the proper sealer resists stains from nearly any industrial chemical.  This not only protects the finish, but the concrete itself. 


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.

Concrete Grinding and Sealing VS.  Polished Concrete

Torn between these two? Well, the answer to your dilemma would be solely coming from you. Your needs will determine whether you choose concrete grinding and sealing or polished concrete. So, before deciding between the two, consider your needs and where you opt to put this flooring installation.

Concrete grinding and sealing are preferable to use in low-traffic areas such as residential areas, office flooring, kitchen set-ups, and restrooms. Although the concrete grinding process in a grind and seal involves fewer steps than the concrete polishing procedure, the end result is still smooth and attractive. Grease, oil spills, stains, and animal urine can all be prevented by grinding and sealing the concrete floor. Chemical-resistant polyurethane sealers can be used on these sealed concrete floors if needed for your area, allowing the floor to be readily washed away from stains that would otherwise cause lasting harm to other flooring systems.

Polished concrete, on the other hand, provides long-term durability as well as densifying, hardening, and dust-proofing properties. Because of its scratch-resistant coating and low maintenance requirements, this system is ideal for high-traffic areas. When properly maintained, it can also last for decades. However, with varied high traffic levels in concrete grinding and sealing, your surface may need to be resealed on a yearly basis. This can be more expensive in the long run than polished concrete in larger settings. When it comes to costs, polished concrete is undeniably more labor demanding, necessitating a larger budget. If you want a polished concrete floor but don’t want to spend a lot of money, a grinding and sealing concrete floor is a good solution.

The Process of Concrete Grinding and Sealing

Depending on the level of quality sought for the concrete finish, the procedures to achieve this flooring can range from a few to numerous intricate steps. The process undergoes five stages, it begins with preparing the floor surface, then proceeds to surface grinding, filling the cracks and holes, cleaning the surface, and lastly surface sealing. To better understand each stage, check the following:

Preparing the floor surface

A new concrete slab may require one sort of surface preparation, while an existing concrete slab may require another. The slab must be cleaned and cleared of any old topping or sealer before a fresh topping aggregate can be installed. The decorative motifs you want to see on the final polished surface can be included in this topping.

Surface grinding

To remove contaminants from the existing slab, the concrete is ground with engineered concrete floor surface grinders. Grinding promotes the adhesion of your concrete to the concrete stain and/or sealer. It is up to a proper judgement to decide how many grinding cycles should be repeated. Increasing the grit number refines the concrete surface to the desired smoothness.

Filling the cracks and holes

Larger holes, divots, and expansion joints that may have formed on the surface as a result of the first grinding process are fixed and filled as needed.

Cleaning the Surface

After that, the surface is thoroughly cleaned in preparation for the last step.

Surface Sealing

A sealer is used to protect and enhance the appearance and durability of your new concrete floor. A sealing solution has been applied to your sealed concrete floor. Your concrete flooring provider will propose the appropriate type of sealer for you based on your floor goals, requirements, and area. Multiple coatings of sealant may be required for softer, more porous concrete, and this type is a regular occurrence in residential areas.
