All about sanding concrete floors

Grinding technology

Grinding is performed with special grinders equipped with diamond or abrasive disks.
You can find out more about our equipment at separate article.

The process involves several steps:

1. Preparation of the substrate - removal of dirt, dust and irregularities, as well as checking the surface for defects and height differences.

2. Coarse Grinding - used to remove significant irregularities, remove defects and level the concrete surface.

3. Finish sanding - used to create a smooth and even surface that is ready for protective coatings or polishing.

4. Polishing (optional) - gives the floor a shine, increases its wear resistance and improves its appearance by making the surface resistant to damage.

5. Sealing and treatment with hardening compounds - protects concrete from moisture, dust and mechanical damage, extending the service life of the coating.

Once the sanding steps are completed, the surface is firm, smooth and ready for further use.

Grinding methods for concrete floors

There are different methods of grinding, the choice of which depends on the required finish and the characteristics of the concrete surface.

• Mechanical grinding - performed using diamond or abrasive disks, suitable for removing defects and surface preparation.
• Wet sanding - used to reduce dust generation, used mainly for polishing.
• Dry sanding - requires an effective dust extraction system as large amounts of concrete dust are generated.
• Coarse sanding - used in the initial stages, when it is necessary to remove irregularities and defects.
• Finish sanding - used to make the surface smooth and even.
• Polishing is an additional step to create a decorative and durable finish.

Once a sanding method has been selected, it is important to consider additional factors that may affect the final finish.

Factors affecting the cost of grinding

Before starting work, it is important to consider the key aspects that affect the final cost of the surface treatment.

• Total area - the price per square meter is reduced for large volumes of work.
• Surface condition - the presence of cracks, irregularities and old coatings increases costs.
• Desired level of sanding - coarse finish is less expensive than fine polish.
• Additional services such as protective coatings, coloring, hardening increase the price.
• Location - the cost of the work may vary depending on the region, remoteness of the site and logistical costs.

Once all of these factors are taken into account, the budget for the work can be more accurately predicted and the best treatment option can be selected.

Project estimate

Forming an estimate requires the evaluation of many parameters. First of all, the area of the object is taken into account: the larger it is, the lower the price per square meter. The condition of the surface plays an important role, as the elimination of defects and preparation requires additional costs.

Also included in the calculation are the costs of materials, specialist labor, equipment rental, transportation and overhead costs. In addition, the complexity of the work is assessed: basic sanding is cheaper than multi-stage treatment with protective coatings and polishing.

For an accurate calculation of the cost is carried out inspection of the object, after which the necessary work is determined and the terms are agreed with the customer.

Where are concrete floor resurfacing applications?

Grinding concrete floors is used in many applications because it provides strength, durability and aesthetic appeal to the surface.

• Industrial enterprises - used in warehouses, plants and factories where wear-resistant coating is required to withstand significant mechanical loads.
• Shopping and office centers - creates a presentable and durable floor covering, resistant to heavy use and regular cleaning.
• Parking lots and parking lots - extends the life of the pavement, protects it from deterioration and facilitates cleaning of contaminants from automotive fluids.
• Residential - used to create a flat, smooth and aesthetically pleasing floor that can be easily finished or decorative polished.

Floor sanding makes the surface more resistant to wear and tear, increasing its performance and reducing the cost of subsequent repairs.
