Floor Construction: Effects of Foundation Grinding

When it comes to floor construction and coating applications, the importance of foundation grinding cannot be overstated. This preliminary step is critical in laying the foundation for a durable and visually appealing floor finish. The process of foundation grinding helps improve the overall quality and longevity of your floor coating. The act of grinding the floor serves as a foundational process that provides a variety of benefits that ultimately contribute to the success of floor coating applications.

Grinding helps enhance primer penetration by effectively opening the pores of the substrate. This improved permeability ensures a strong bond between the base surface and subsequent coatings, thereby enhancing the structural integrity and longevity of the flooring. And the polishing effect directly affects the quality and beauty of the entire floor. When performed with precision and attention to detail, proper sanding produces a smooth, even surface that minimizes the risk of pitting and unevenness in the floor coating. Conversely, inadequate or incorrect grinding techniques can result in imperfections and inconsistencies in the floor finish, compromising its visual appeal and structural integrity.

Additionally, the effects of sub-par grinding extend beyond aesthetics and can ultimately lead to functional defects and premature degradation of the floor coating. If the grinding process is defective, the primer may not penetrate the substrate effectively, resulting in poor adhesion and vulnerability to damage. This can cause extensive peeling of the floor coating and shorten its lifespan, ultimately leading to the need for premature repair or replacement.

Essentially, the meticulous execution of foundation sanding during floor construction is critical to priming the base surface to effectively accept subsequent coats. Sanding provides the foundation for a durable, beautiful, and long-lasting floor finish by ensuring that the primer penetrates properly and creates a smooth, even surface. By recognizing the critical role of base grinding in floor construction, stakeholders can prioritize this critical step to optimize the quality and performance of floor coatings.

The role of floor grinding

1. Remove loose attachments from the floor

The main goal of this procedure is to eliminate loose attachments on the floor, including laitance and unstable surface cement, thereby laying a solid foundation for the subsequent application of floor coatings. The floor grinding process plays a key role in establishing a stable foundation for your flooring system by carefully polishing the floor surface to remove loose attachments and unstable elements. This careful preparation promotes a strong connection between the floor coating and the ground, minimizing the potential for problems such as swelling and delamination that can occur if loose attachments are not addressed. The importance of effectively removing loose attachments during floor grinding cannot be underestimated. Failure to do so can result in loss of adhesion and structural instability, which can lead to a host of problems with the finished flooring system. When loose attachments are not completely polished and removed, the risk of bumps, unevenness, and delamination increases significantly, compromising the integrity and aesthetics of the final floor surface.

2. Brushed surface to increase adhesion to the ground

Flooring such as terrazzo, ceramic tile, and emery, which are known for their strength and hardness, undergo a meticulous polishing process that roughens the surface. This intentional surface roughening significantly enhances adhesion, enhancing the overall durability and longevity of the flooring system. The floor grinding process plays an important role in creating a brushed surface to optimize adhesion to the floor. By increasing the roughness of the floor surface, the effectiveness of primer penetration is significantly improved. The resulting increased gravitational force between the substrate surface and coating allows for a strong and secure adhesion, enhancing the basecoat’s ability to withstand daily wear and tear. The enhanced adhesion of floor grinding not only ensures the stability of the floor coating but also reduces the risk of premature wear, peeling, or delamination.

Steps to polish floor

1. Basic preparation for effective floor polishing

Thoroughly Cleaning the Floor Surface of Dust and Debris. By eliminating stains and debris, the floor can be optimally polished, free of blemishes and blemishes. Additionally, where machinery and equipment are located on the premises, it is vital that owners or relevant personnel are alerted to relocate or secure these items. This proactive measure prevents potential damage to machinery and equipment caused by residual dust from the floor polishing process. By reducing the risk of dust-related damage, both the floor and surrounding assets are protected, ensuring a harmonious and efficient polishing job.

2. Choose the appropriate floor grinding tool according to the ground conditions

Different floor conditions require the use of specialized grinders and discs to address the unique characteristics of the floor surface. Whether you’re working with concrete, stone, or other materials, proper selection of abrasive tools is crucial to getting the best results. Careful consideration of factors such as hardness, texture, and potential imperfections in ground conditions is essential to guide the selection of the equipment and grinding discs best suited for the job. Additionally, the importance of avoiding using grinding discs and machines from different manufacturers cannot be overstated. One notable issue caused by grinding tool mismatch is the difference in grinding disc thickness, which can lead to inconsistent grinding efficiency. Thickness differences between polishing pads from different manufacturers can affect the accuracy and uniformity of the polishing process, potentially resulting in poor results and a poor finish. By following recommendations for using sanding discs and machines from the same manufacturer, individuals and professionals can reduce the risk of encountering compatibility issues and ensure a seamless and efficient polishing experience. This alignment not only guarantees a harmonious match between the device and disc but also maintains the precision and reliability required to achieve excellent results on different floor surfaces.

3. Use the criss-cross method to polish more than two times

Achieving an evenly polished floor requires attention to detail. When using the criss-cross method, it is recommended to sand the floor at least twice to ensure that no areas are missed. Additionally, maintaining a consistent walking speed when sanding is critical to preventing deep and shallow unevenness. For corners, edges of equipment, or areas that a dustless grinder cannot reach, it is recommended to use a hand grinder and vacuum cleaner, taking care to avoid damaging walls or equipment.

4. Clean the dust from the floor

After polishing, the dust and debris on the floor must be cleaned in time. This step ensures that the polished surface remains pristine and free of any unwanted particles, ultimately adding to the aesthetics of the space.

Standards for floor polishing

1. Sanding and loosening the ground

According to the degree of looseness of the foundation concrete, choose grindstone grinding discs or coarse sand discs of different meshes for polishing. There are many areas where the strength is not very good, and the loose areas must be polished to strong areas.

2. Polishing hard ground

To polish hard surfaces such as terrazzo, emery, ceramic tiles, and concrete floors to excellent hardness, it is crucial to choose grinders and diamond grinding heads corresponding to different mesh sizes, each of which is suitable for the specific needs of the respective floor. Achieving strong adhesion can be challenging given the inherent stiffness and density of these materials. Therefore, the entire surface must be roughened to enhance the bonding effect between the floor paint and the ground. Careful selection of the right tools and techniques for grinding these tough materials will ensure a successful and long-lasting bond, ultimately extending the life of the floor and maintaining its quality.
