Selecting the right abrasive tools is a critical step in concrete floor grinding and polishing. Choosing the correct bond not only extends the life of your diamond pads and enhances floor gloss but also helps you effectively control costs and increase project profitability. 1. What is a Bond? The "bond" is the metal matrix that holds the diamond particles in place within the tooling. During the grinding process, the bond gradually wears away, continuously exposing fresh, sharp diamonds to maintain efficient cutting performance. Golden Rule for Bond Selection: Hard Floors → Use Soft Bond (Faster wear, continuous diamond exposure, prevents under-polishing) Soft Floors → Use Hard Bond (Slower wear, prevents over-cutting, extends tool life) If you are unsure of the floor hardness, we recommend using a Mohs hardness tester or conducting an on-site test grind. If testing is not possible, opting for a medium bond is the safest and most versatile solution. 2. Three Main Bond Types & Their Applications Bond Type Suitable Floor Types Key Characteristics Hard Bond New concrete, asphalt, dusty or abrasive substrates Wears slowly, protects against excessive abrasive consumption, ideal for softer or more porous surfaces Medium Bond Most common concrete types, refurbished floors, mixed substrates Highly versatile, consistent performance, the most commonly used and reliable choice for contractors Soft Bond Super-hard surfaces (e.g., terrazzo, heavily hardened concrete) Wears quickly, aggressive diamond exposure, prevents glazing and under-polishing on hard floors ⚠️ Warning: Using the wrong bond can lead to "glazing" (where the metal bond covers the diamonds, stopping them from cutting) or abnormal wear – both of which waste significant time and money. 3.

How to distinguish the quality of the floor grinder? The floor grinder is mainly used for related construction work on the ground. It can effectively grind terrazzo, epoxy mortar layer and concrete surface, etc., to make the floor more flat, smooth and clear. Compared with the previous manual grinding of the floor, the time cost is greatly reduced, the work efficiency is improved, and the grinding effect of the floor is also obvious. So how to distinguish the quality of the floor grinder? What brand do you recommend buying? We analyze from the following aspects: Efficiency and durability are the key to buying a floor grinder. There are four main factors that determine efficiency: 1. Grinding area 2. Machine weight 3. Motor power 4. Whether the gearbox is integrated or split. The integrated gearbox generally adopts one-stage gear transmission, which means that the output of the motor can be transmitted to the grinding disc to the maximum extent. In addition, it depends on the after-sales service. No matter how good the manufacturer is, they can’t guarantee that all equipment will not have problems during use. Once there is a problem, if the after-sales service fails, they will often return to the factory for repairs, not to mention whether there are maintenance costs and round-trip fees. How much, just a few days of delay in work will not be enough for workers to eat, live and pay, and the construction period will be delayed, so after-sales must be in place. On the premise of efficient and durable after-sales service, we need to look at other configurations, such as: 1. Can the frequency be converted 2. Whether the motor is iron shell or aluminum shell 3. Whether the motor has overload protection and over temperature protection 4. What are the dust prevention measures? 5. How many oil seals are there in the gearbox? 6. Whether there will be oil leakage 7. Is the counterweight iron integrated and adjustable?

The performance of the concrete grinder includes: grinding width, grinding head running mode, speed, grinding head unit pressure, water volume control, etc. The construction criteria are divided into: flatness, clarity and gloss.   1. Grinding area of concrete grinder: Relatively speaking, the larger the grinding area of the machine, the higher the flatness of the construction ground, but it is also the increase in the grinding range that reduces the leveling efficiency of the ground level difference.   2. The operation mode of the grinding head of the concrete grinder: the more complex the operation mode of the concrete grinder, the greater the grinding force, the higher the work efficiency, and the higher the ground clarity. The grinding force of the two-way 12-head concrete grinder is stronger.   3. The rotation speed of the floor grinder: Generally, the higher the rotation speed of the concrete grinder grinding head, the higher the grinding force. However, an excessively high speed will reduce the grinding force of the abrasive and the ground. When the pressure of the grinding head is relatively low, the stability of the machine operation will be reduced, and the construction standard will be reduced at the same time.   4. The unit pressure of the grinding head of the floor grinding machine: the grinding head pressure of the floor grinding machine is even the weight of the machine. The greater the grinding head pressure, the higher the relative efficiency and the leveling rate. For the construction on the ground that is too soft, if the grinding head pressure is large and the cutting force increases, the floor grinder cannot run at a uniform speed at this time, which will reduce the construction flatness.   5. Water volume control: Generally, grinding on the ground is divided into wet grinding and dry grinding, which mainly determines the ground. Water can play the role of lubrication, chip removal and cooling. With the change of the grinding process on the granite hard floor, the amount of water should be controlled in time. The ground grinding temperature will also directly affect the grinding brightness.   Through the introduction of the performance of the floor grinder, I believe that after understanding the performance of each part of the concrete grinder, it is easy to choose a concrete grinder that better suits your needs.

How to prevent epoxy floor cracking? Defect status: (1) Epoxy floor fine cracks: After the coating film is applied, it is difficult to identify with the naked eye, but it can be clearly observed with a tenfold microscope. It is the rupture of the surface of the coating film caused by the shrinkage force inside the coating exceeding the cohesive force of the coating film itself. It does not damage the beauty of the coating film and is the inevitable result of the aging of the coating film. But if this happens soon after painting, it's a pathological condition. (2) Coarse cracking of epoxy floor: The coating film produces obvious coarse cracks shortly after coating, and sometimes the bottom is visible. (3)) Epoxy floor cracks: After the coating film is coated, the shape is similar to the cracks on the tortoise back. A similar phenomenon occurs in crocodile skin cracks and glass cracks. Epoxy floor cracking reasons: 1. After the coating film is dried, the hardness is too high, and the flexibility is poor, such as the coating prepared with fatty acid containing a common double bond or its ester; 2. Apply a second coat of paint before the first coat is dry, and the inner and outer stretches of the two coats are inconsistent; 3. The coating is not properly matched, for example, the primer layer is softer than the topcoat layer; 4. There are too many volatile components in the epoxy floor topcoat, which affects the bonding force of the film and causes the coating film to dry and crack; 5. The coating is too thick, the surface layer is dry but the inner layer is not dry; 6. Excessive amount of drier or improper combination of various driers; 7. The coating film is applied in the environment with polluted gas (such as sulfur dioxide, ammonia, etc.); 8. The color paint is not stirred evenly before use, the upper layer has more resin and less pigment, and the lower layer has more pigment and less resin, which is easy to crack after painting; 9. The coating has poor weather resistance or temperature resistance Epoxy floor cracking treatment countermeasures: 1. The hardness of the topcoat should not be too high, and attention should be paid to the flexibility of the coating film in the coating formulation; 2. The second coat should be applied after the first coat is fully dry; 3. Solve the compatibility of the coating through the test, generally make the hardness and elasticity of the primer coating 4. and the topcoat close to; 5. The volatile components of epoxy floor topcoat should not be too much; 6. Each coating film in epoxy floor construction should not be too thick; 7. Pay attention to the dosage and collocation of the drier; 8. Construction and long-term use in a polluted environment should be avoided; 9. The color paint should be fully stirred before construction; 10. Pay attention to the ambient temperature of the paint;

Why does the epoxy floor produce color difference? The reasons why epoxy resin floor produces color difference: 1. The main agent of epoxy resin coating is precipitated and not fully stirred evenly; 2. The material is poured on the ground, and the contact time with the front seam is too long; 3. The coating thickness is uneven; 4. The coating material is cut off during construction; 5. Use different batches of topcoats. The prevention method of why epoxy resin floor produces color difference: 1. The additives should be fully stirred before epoxy floor construction; 2. Avoid too long a contact interval with the front seam, and construct the entire operation line together as much as possible; 3. Try to use fixed tools and strengthen the construction proficiency of construction personnel; 4. Epoxy resin coating needs to be prepared at one time to prevent material breakage; 5. Use the same batch of epoxy paint as much as possible.

Floating problem caused by curing agent After the coating is cured and formed into a film, the separation phenomenon will occur due to the use of the floor material. The main reason is related to the particle size, crystallization, molecular polarity and surface charge of the pigment. Generally, the separation is divided into vertical separation and horizontal separation. Vertical separation is generally called blooming, and horizontal separation is generally called floating color. In the same material A, after changing the curing agent, floating color occurs. This situation shows that there is no problem with the particle size and crystallization of the pigment. The main problem is the molecular polarity of the color. Because inorganic pigments are divided into polar and non-polar, at the same time, the diluent in the curing agent is also divided into polar solvents and non-polar solvents, sometimes the molecular polarity of A material is the same as that of the diluent in a curing agent. The polarity is just the opposite, and the curing agent does not produce floating color. After changing the floor curing agent, floating color occurs, which is only related to the molecular polarity of the color. Generally, adjust the dispersant to reduce the polarity, or in Add an appropriate amount of silicon coupling agent to material A to reduce the polar repulsion phenomenon and increase the aggregation force of inorganic pigments and organic pigments.
