The concrete floor grinder is a  specifically design to grind the concrete floor. It can grind, level, and polish the floor, so that the coatings and loose layers on the floor surface can be removed. However, the actual concrete floor conditions are different, it can be soft,or hard, or ash, or damage, or uneven etc. If you encounter an extremely hard floor, even the floor grinding machine can't cut it off, what should we do at this time? 1. Change the small one to a large concrete grinder or put an extra weight on it to increase the grinding pressure 2. Use soft bond grinding pads,or sharper abrasives diamond grinding discs, or low grit of concrete grinding plates. 3. Reduce the rotation speed and forward speed of the floor grinder. 4. Wet the concrete surface, or use wet grinding. Whether it is a floor grinder, or diamond abrasive grinding pads or other concrete grinding materials, it is necessary to choose the appropriate one according to the floor conditions, so as to facilitate the floor construction.

For those who are new in concrete polished flooring, they often carry out the construction work with previous experience. Some of them may ask if the concrete hardener densifier can be directly mixed in the concrete and used in the next process.If it's ok may save lots of manpower. But what we would like to tell you is that it is not feasible to use concrete densifier by mixing with concrete. From its working principle, the concrete sealer curing agent reacts with the calcium and magnesium ions in the concrete through infiltration to make the concrete denser and harder. In terms of construction conditions, generally speaking, after rebuilding the floor ground, the process of concrete hardening won't be carried out until after 7-14 days of water conservation. From an economic point of view, this is not a good deal. If this conjecture can come true, how much concrete sealer densifier we need to invest to make an equivalent solidified floor? According to normal construction, we just apply concrete hardening curing agent to its surface and get a dense hardened concrete surface. If it is directly stirred, what proportion of concrete sealer hardener need to be added in order to ensure quality of floor finished?There is no answers. In conclusion,it's impossible to mix concrete hardener and concrete up together to use.

Recent years, with the popularity of polished concrete floorings, the application of decorative concrete has become more and more widespread and been applied to various fields. For colored flooring,we have two diffierent type: epoxy floors and concrete dyeing floors.The performace and applications of these two types are different. So, what is the difference between a concrete dyeing floor and an epoxy floor? Analysis from abrasion resistance part,epoxy flooring is directly painted on the surface with epoxy paint on the basis of the original floor. Although it can protect the floor, but it is a coating on floor surface, especially after heavy pressure and poor maintenance, peeling and other phenomena will occur over time. Overall, the wearing resistance is not as good as the concrete dyeing flooring. The concrete dyeing floor is a permeation dyeing process to the cured concrete floor with concrete dyeing agent, instead of forming a coating. It can be said that it has almost the same life as the cured floor,with excellent abrasion resistance. As for appearance,since the epoxy floor is a coating directly formed on the floor surface, the color is more uniform and more diverse, which can cover some defects of the floor surface. In addition, the concrete dyeing flooring is dyeing with dyeing agent to concrete floor. The concrere dying agent penetrates into the floor, Whether the color is even or not has been influenced by the base of the flooring. The base of the floor is different from place to place. Loose floor surface will absorb more dyeing agents, and denser floors will absorb less agents，resulting in that the color is less uniform than epoxy flooring.

Do you know the epoxy flooring system structure? The structure of floor coating can be divided into three parts from bottom to top: primer, floating coating and surface coating. And do you know what's the function of them? Primer of Epoxy Flooring System Structure: The primer requires good permeability, no pigment filler, and good alkali resistance. Its functions are as follows: 1. Close the concrete pores to eliminate the tidal bulge problem caused by,and enhance moisture-proof fixing effect. 2. Strengthen the bonding strength of the base surface. 3. Increase the adhesion between the base layer and each layer. Floating Coating: The middle coating is mainly composed of film-forming materials and aggregates that improve mechanical properties, such as quartz sand. Its functions are as follows: 1. Effectively fill the surface voids of the concrete base and improve the strength of the floor system. 2. Make the surface of the floor smooth and easy to paint. The thickness of the intermediate coating is controlled at 0.5-3mm. Surface Coating: The topcoat is direct contact with environment and air. The aesthetic effect of the epoxy floor also depends on the surface coating. For topcoats, it is generally required to have good abrasion resistance and mechanical strength,so that it can resist the external shocks and the effects of ground thermal expansion and contraction.In addition, the surface decoration effect of topcoat is very good, if necessary, it also has anti-slip and corrosion resistance.

The floor grinder is mainly used for related construction work on the floor ground. It can effectively grind the floor surface more smooth and clear,such as terrazzo, epoxy mortar layer and concrete surface layer etc. Connected with a vacuum cleaner,it can be worked dust free. It's the ideal equipment for floor engineering treatment.It can grind and polish floor surface to a flat and bright floor by installed with diffirent types of grinding diamond discs,polishing pads and bush hammer. Please be kindly to note the following points to know whether the floor grinder is good or bad: 1. Smooth operation, Smooth operation is the prerequisite to ensure the stable operation of the machine, which can reduce the failure rate of the machine; 2. Speed of grinding. The speed of grinding determines the working efficiency. The working speed of a floor grinding machine will directly affect the construction cost and profit of the constractor. 3. Reliability of operation To understand how high the failure rate of machinery, safety is always important. 4. The finial effect of floor grinding Observe the smoothness and gloss of the floor surface after grinding and polishing. Be sure to read the instruction manual before using the floor grinder, and if you have any problem in operating the machine,please ask someone to guide you.

High Tech Grinding Concrete Floor Polishing System is a polished concrete floor that go through equipment grinding,abrasive polishing and chemical reaction. It works with a floor grinder to dry-grind floor surface,and creates a high brightness,high hardness and high density concrete floor. Why we choose a dry grinding method to achive a polished concrete floor? Dry grinding is more environmentally friendly. Sewage and mud produced by wet grinding are more troublesome to clean up. If it is discharged directly into the sewer, it will polute the environment,and when they dry up may cause blockages. The dust produced by dry grinding is not good for human health, but it can be cleaned up by a industrial vacuum cleaner to achieve dust-free floor grinding. What are the benefits of dry grinding for concrete floor construction? ▶Dry grinding is more secure and has strong visual recognition ability. Even if there is dust, it only needs to be cleaned. It is more convenient to observe the floor grinding effect.However the sewage and mud produced by the wet grinding will hinder the workers' observation of grinding effect. ▶Dry grinding is more efficient and reduces labor costs.  By connecting a vacuum to a floor grinding machine when dry grinding can create dust-free construction working environment.It will save the trouble of cleaning slurry,which produced by wet grinding,and dry grinding artificial dust removal,which is more effiecient and less manpower. High Tech Grinding Concrete Floor Polishing System adopts dry grinding to cure concrete floor, so as to achieve dust-free grinding of the floor, improve the floor construction efficiency, reduce labor intensity, and make polished concrete effect better.

The six major concrete repairing ways of High Tech Grinding system include grinding, cutting, drilling, batching, polymer mortar, and affusion.And among which there is a special repair process for the hollow floor---affusion method. How to use affusion way to repair the empty drum concrete? The grouting nozzle is buried in the empty drum position for filling, and the hollow drum position is filled to ensure the integrity of the concrete. Repair process: ★ Preparation before construction 1. Confirm the empty drum position that needs to be treated. 2. Drilling at the empty drum position, surface cleaning, and embedding the slurry nozzle. ★ Chemical grouting 3. Grouting is carried out after the grouting nozzle is installed. The grouting pressure and amount are determined according to the specific conditions of the empty drum part. 4.After preparing the grouting resin,pour it into the container of the grouting machine. 5. Fill the grout resin into the empty drum position with a high-pressure grouting machine, while confirm the filling is full, close the valve immediately. When grouting, it is necessary to prevent the grouting liquid from overflowing from other holes and causing waste. Confirm that the grouting is completed and remove the implement. 6. After 48 hours, the resin was initially coagulated; after 7 days of dry curing, it can be used normally. The infusion method uses grouting to repair empty drums, and the time is fast, and the base layer will not be damaged, especially for the underground garage, factory building, etc.,  the construction process does not affect the owner's use, which is a convenient way.
