1. Preparation
The effectiveness of any treatment applied to concrete is intrinsically linked to the thoroughness of the initial preparation. Inadequate surface preparation is a primary cause of coating failure, delamination, and inconsistent color absorption. Contaminants such as dust, oil, existing coatings, and laitance (a weak, powdery layer on new concrete) prevent proper bonding between the concrete and the applied treatment. For example, applying a stain to a surface contaminated with oil will result in uneven coloration and potential rejection of the stain. The preparatory phase sets the foundation for subsequent steps; therefore, its importance cannot be overstated.
Surface profiling, a critical component of preparation, involves creating a suitable texture for mechanical adhesion. This can be achieved through various methods, including grinding, shot blasting, or acid etching, depending on the existing surface condition and the type of treatment to be applied. A smooth, polished concrete surface, for instance, requires a different preparation approach than a rough, troweled surface intended for an epoxy coating. Correct profiling ensures a strong mechanical bond, preventing premature wear and maximizing the lifespan of the finished surface. For instance, an epoxy coating applied to a properly profiled surface will withstand significantly higher impact forces and abrasion compared to one applied to a smooth, unprepared surface.
In conclusion, thorough preparation is not merely a preliminary step but an integral element of concrete treatment success. It addresses contamination, ensures proper adhesion, and establishes a foundation for the longevity and aesthetic quality of the final surface. Ignoring or underestimating this stage will inevitably lead to compromised results, increased maintenance costs, and a reduced lifespan of the treated surface.
2. Sealing
Sealing constitutes a critical phase in the completion of concrete surfaces, serving as a protective barrier against environmental factors and prolonging the lifespan of the floor. Without adequate sealing, concrete is susceptible to damage from moisture, chemicals, and abrasion, diminishing its aesthetic appeal and structural integrity. The process involves applying a penetrating or film-forming sealant to the concrete surface, effectively mitigating these risks.
- Moisture Protection
Concrete is porous, allowing water and other liquids to penetrate its surface. This can lead to cracking, spalling (surface flaking), and the growth of mold and mildew. Sealants create a barrier that prevents moisture intrusion, safeguarding the concrete from these forms of degradation. In regions with freeze-thaw cycles, moisture absorbed into the concrete can expand upon freezing, causing significant damage. Sealing is, therefore, essential for preserving concrete floors in such climates.
