How to use the floor grinder in the floor construction?
Jul 04 , 2022

For the construction of solidified floor, it is not only materials, but also construction tools and technology that are important. We should choose appropriate tools and master the key of construction. Grinding tools must be prepared before grinding the concrete sealing curing agent. Select appropriate construction equipment to meet use requirements. Then, as a kind of engineering machinery, the ground grinder is a kind of mechanical equipment that can carry out precision grinding and polishing, so it can process and polish some workpieces, but its process is relatively complex, which can not be completed in one step, and it requires multiple steps and links to achieve the desired effect.


TransGrind is a professional manufacturer of diamond tools for concrete or stone floor grinding and polishing, we have supplied many different kinds of diamond tools for many customers, such as Scanmaskin tools, Lavina tools, Klindex tools, Husqvarna tools, HTC tools etc.Welcome to consult for our products by clicking pictures to get into our official web if you are interested.


Use Steps of Curing Ground Grinder

① When rough grinding the floor with metal concrete grinding pads: select appropriate concrete metal parts (30#60#80#) according to the flatness and grinding condition of the floor.

② When ground fine grinding and resin concrete grinding pads rough grinding: select the appropriate concrete resin grinding pads and polishing pads.(50#100#200#400#800#3000#6000#10000#)


Detailed Description of Specific Operation Steps

1. Select and install the appropriate grinding plate according to the construction process.

2. Step on the extended lever with your left or right foot, and one person can easily pry the heavy grinder and gently level the floor grinder.

3. Adjust the operating handle to a proper position.

4. Add an appropriate amount of clean water to the water tank. If choose dry grinding, there is no need to drain water and a dust collector is equipped.

5. Install the protective cover.

6. Check that the switch of the machine must be in the "off" position, connect the power line correctly, insert the plug into the socket of the machine body, and the red indicator light will be on after the power is connected.

7. Turn on the water switch, put in an appropriate amount of water, and start the grinder after about 5 seconds (the forward / reverse switch, note that the speed knob switch cannot be lower than the third gear when starting, and can be adjusted at will after starting), and then grind the whole (up, down, left, right) into a "#" shape to ensure the overall flatness, avoid refraction, and check while grinding until it is flat.

8. When wet grinding, use a water suction machine to absorb sewage, and when dry grinding, use an industrial vacuum cleaner to absorb ground dust. Check the floor level.

9. Replace the floor grinding plate and grind it into a "#" shape (up, low, left and right). Each polishing and the previous polishing press each other for about 20cm, and do not jump away from the polishing.


Precautions for Polishing Solidified Floor

1. 300 mesh before grinding and should not be too fast.

2. It is very important to choose the appropriate grinding equipment, which will affect the later material wear. It is generally not recommended to use large machines, except terrazzo and super flat ground.

3. Terrazzo floors with metal strips as separators cannot be polished into highlights, because the metal strips will turn black when heated.

4. 500 mesh is very important. When the brightness requirement is not high, you can use 500 mesh to start grinding.

5. When using mechanical polishing, it is necessary to maintain a uniform speed. Too fast or too slow will lead to serious uneven surface of floor materials.


Concrete curing agent is a colorless and odorless liquid used for curing floors. It penetrates into the concrete and reacts with the substances in the concrete to produce hard substances, so as to effectively improve the compactness, strength, hardness, wear resistance and impermeability of the concrete surface.
