Surface Preparation: Importance of Mechanical Grinding & Concrete Surface Profiles

Updated: Jun 6

Surface preparation is an absolutely essential step in the process of applying a new coating to a concrete surface.

High-performance grinding equipment used for mechanical surface preparation of concrete floors, essential for creating a robust and durable epoxy flooring system.

Its significance cannot be overstated, as it wields the power to determine the success or failure of the final product. The durability, appearance, and overall lifespan of the coating all hinge upon this pivotal stage. Among the array of methods available for surface preparation, mechanical grinding emerges as an unequivocally superior choice. But why, you may wonder? And what are the distinct concrete surface profiles that exist? Let us delve into the details.

The Importance of Surface Preparation:

Surface preparation assumes paramount importance as it lays the foundation for the seamless adherence of the coating to the concrete surface. This process eradicates any remnants of prior coatings, oils, dirt, or other contaminants that may impede the new coating's ability to form a steadfast bond. It also serves to unseal the surface pores of the concrete, permitting deeper penetration of the coating and facilitating the establishment of a robust, long-lasting connection.

Without the proper preparation of the surface, coatings are doomed to a fate of peeling, chipping, or cracking in the wake of their application. Premature failure inevitably ensues, leaving behind a trail of exorbitant expenses and arduous repairs. Thus, it becomes unequivocally clear that the longevity and durability of a concrete coating are primarily determined before it is even applied, underscoring the vital importance of conducting thorough and professional surface preparation.

Mechanical Grinding: The Unparalleled Method

Mechanical grinding ascends to a position of unrivaled prominence among the myriad of techniques available for surface preparation. It stands head and shoulders above the rest for a multitude of reasons:


Mechanical grinding bequeaths a uniform surface finish, ensuring an even distribution of the coating across the entirety of the concrete surface.


This method possesses an inherent adaptability, capable of accommodating surfaces with varying degrees of hardness or abrasiveness. Moreover, it adeptly handles both vast expanses and arduous-to-reach crevices with equal proficiency.


Unlike certain other methods, mechanical grinding abstains from employing harsh chemicals that may pose a threat to the environment or human health.


Mechanical grinding, particularly when confronted with substantial surfaces, invariably outpaces alternative approaches, thus reducing project timelines and expediting progress.


Ultimately, mechanical grinding bestows unparalleled adhesion upon the new coating. This remarkable attribute enhances the coating's performance and augments its lifespan to a remarkable extent.

Understanding Concrete Surface Profiles (CSP):

Concrete Surface Profiles (CSP) serve as a standardized metric, providing a comprehensive assessment of the roughness exhibited by a concrete surface. The International Concrete Repair Institute (ICRI) has meticulously crafted guidelines, meticulously outlining nine distinct levels of CSP, ranging from the nearly flat (CSP 1) to the markedly rough (CSP 9).

The selection of the appropriate CSP for a given project hinges upon the nature of the coating or overlay intended for application. Thin coatings may necessitate a CSP of 1-3, while thicker overlays demand a more substantial CSP of 5-7. This decision is of paramount importance, as it exerts a profound influence on the bond strength, permeability, and thickness of the coating.

Mechanical grinding may be adroitly adjusted to achieve a diverse array of CSP levels. By astutely selecting the optimal combination of grinding machine, abrasive, and technique, seasoned professionals skillfully prepare the surface, imbuing it with the ideal roughness requisite for the intended coating.

Why Does All This Matter?

Surface preparation for concrete coatings looms large as an indomitable prerequisite, wielding an incontrovertible influence over the durability and lifespan of the ultimate product. In this regard, mechanical grinding reigns supreme, brimming with attributes that render it unparalleled in efficacy. Its consistency, versatility, eco-friendliness, and efficiency converge to bestow the coating with unparalleled adhesion, thereby augmenting its performance and longevity. A comprehensive comprehension of the distinct Concrete Surface Profiles and their intricate relationship with various coatings elevates the outcome, endowing it with an optimal foundation upon which the new coating may gracefully thrive.

Tru-Grit Epoxy Flooring resolves concrete surface profile issues through:

Accurate CSP Measurement:

At Tru-Grit Epoxy Flooring, we utilize the ICRI standard classification system to precisely measure the surface profile of concrete. This standardized approach allows us to quantitatively assess the roughness or texture of the surface, crucial for selecting the appropriate preparation method. By adhering to this system, we ensure that each project receives the correct CSP.

Expert Surface Preparation:

With years of experience in concrete surface preparation, we employ cutting-edge equipment and techniques to achieve the desired CSP. Our services include shot blasting, diamond grinding, and other methods tailored to coatings and treatments. Shot blasting guarantees a uniform CSP, while diamond grinding achieves specific smoothness or roughness levels.

Customized Solutions:

Recognizing the uniqueness of each project, we provide customized solutions. Factors such as concrete age, condition, coating type, and desired outcome are carefully considered. For aged or deteriorated concrete, we employ more aggressive preparation to eliminate loose or damaged material before applying coatings.

Improved Adhesion:

Our meticulous attention to achieving the proper CSP ensures optimum adhesion between coatings, treatments, and the concrete surface. Improper bonding can result in peeling or flaking. Tru-Grit Epoxy Flooring's surface preparation guarantees a strong mechanical bond, leading to a longer-lasting, more durable finish.
