Choose the right diamond grinding pad for effective floor grinding

When it comes to floor treatment, using the right tools is crucial to achieving the desired results. One such tool is the diamond grinding pad, which is an indispensable component in the floor grinding and renovation process. However, choosing the appropriate diamond grinding disc requires consideration of factors such as usage experience, construction technology, and construction methods. In this article, we’ll take an in-depth look at the construction process and guide you on how to choose the right grinding disc for each stage to optimize efficiency and achieve outstanding results.  

Choose according to the construction process

The floor treatment construction process usually follows the steps of leveling, rough grinding, fine grinding, and final polishing. Each stage requires specific tools and techniques to ensure a smooth, flawless completion.

Leveling: During the leveling phase, it is crucial to choose a durable and efficient diamond disc. Thick grinding discs are preferred in this initial step as they help smooth out any unevenness or blemishes on the surface, creating a level base for subsequent stages. These discs have excellent leveling capabilities, allowing for a more precise floor treatment process. By using thick grinding discs, construction efficiency can be significantly improved.

Coarse grinding: During the rough grinding stage, it is crucial to choose a diamond disc that can effectively remove deep scratches or highlighted unevenness left after leveling. It is again recommended to use thick grinding discs at this stage. Their greater density and larger abrasive surface ensure more efficient removal of defects, saving valuable time and effort while maintaining the structural integrity of the floor surface.

Fine grinding: Entering the fine grinding stage, the goal is to obtain a smooth and uniform surface in preparation for the final stage of polishing. For this task, it is recommended to use a thin grinding disc instead, which allows for finer control and precision. Thin grinding discs offer greater flexibility, allowing them to reach and treat hard-to-reach areas and floor edges. This ensures a consistent finish and prepares the surface for the final polishing stage.

Polishing: To achieve the ultimate shine and shine, the polishing stage requires the use of thin abrasive discs. These discs are highly precise and provide maximum contact with the floor surface, ensuring optimal results. By choosing the right thin grinding disc for this stage, you can achieve the desired results, transforming your floor into a spectacular display of elegance and beauty.

Choose according to the construction method

For dry grinding treatment methods, it is recommended to use concrete dry grinding discs. These discs are designed specifically for dry grinding, providing better performance in such applications. On the other hand, for wet grinding treatments, concrete dry grinding discs can also be used. However, it is worth noting that the lifespan of these discs may be slightly shortened when used for wet grinding. Wet grinding involves the use of water to cool and lubricate the grinding process, which accelerates the wear of the dry grinding discs. When polishing floors, thin discs are preferred for better results. These discs provide a finer finish and are capable of achieving a smoother, more polished surface. High-speed dry polishing is also recommended for efficient and effective polishing.

Benefits of wet sanding concrete floors

1. Wet grinding helps the environment

Wet grinding does have several environmental benefits compared to dry grinding methods. Here are a few reasons why wet grinding is considered more environmentally friendly: Reduced Dust: Wet grinding produces less dust than dry grinding. This is good for the health and safety of workers and also helps reduce air pollution in the surrounding environment. Save water: Wet grinding requires water as lubricant and coolant. However, water can be recovered and reused during the grinding process, reducing overall water usage. Waste Management: The slurry produced by wet grinding is easier to manage and dispose of than the residue from dry grinding (usually fine dust particles). Energy efficiency: Compared to dry grinding, wet grinding can be more energy efficient because the water used in the process helps cool the grinding tool and reduces friction, thereby reducing energy consumption.

2. Wet grinding helps extend disc life

Wet grinding helps extend the life of the grinding disc when working with medium to high-hardness materials. Here are a few reasons why wet grinding is beneficial in this regard: Cooling effect: Wet grinding uses water as a coolant to help dissipate the heat generated during the grinding process. This cooling effect prevents the grinding disc from overheating, reducing wear and extending its service life. Lubrication: Water acts as a lubricant in wet grinding, reducing friction between the grinding disc and the material being ground. This helps prevent excessive heat generation and minimizes wear on the disc, extending service life. Material Removal: Wet grinding can promote material removal more effectively than dry grinding. Water helps soften and loosen the material being ground, allowing the grinding discs to cut deeper into the surface, exposing aggregate and achieving the desired grinding effect more quickly.

3. Wet sanding helps create a matte finish

Using the wet grinding method, you can use higher mesh grinding discs to create a relatively matte effect, and it also facilitates daily maintenance of the floor. The first 2 or 3 polishing steps, if used with water grinding, can help remove the scratches left by the metal grinding discs on the ground.

Benefits of dry grinding concrete floors

1. Highlight effect: One of the main benefits of dry sanding concrete floors is the ability to achieve a high-gloss finish. Dry sanding creates a smoother surface and enhances the reflective properties of the floor compared to wet sanding. The absence of water during the grinding process allows for better control of the polishing compound and produces a more consistent mirror finish. This high-gloss effect not only adds to the aesthetics of the floor, it also increases light reflectivity, making the space appear brighter and more spacious.

2. Soft concrete floor: Soft concrete floors, while generally sound-absorbent and comfortable, can present challenges during the sanding process. These floors tend to consume abrasive discs with hard substrates, resulting in increased costs and decreased profitability. Wet sanding (requiring the use of water during the grinding process) can also cause scuff marks on soft concrete floors because the grinding disc is too sharp. This is where dry grinding comes into play. The dry sanding method is more suitable for soft concrete floors as it allows better control of the abrasive, preventing excessive wear and minimizing the risk of leaving unsightly marks on the floor surface.
