How to polishing concrete floor

The ground is the most frequently used one among the six-sided buildings, and it is also the most easily damaged, especially in the workshops and underground garages of heavy industry enterprises. The continuous exchange of industrial forklifts and vehicles will cause the ground to be damaged and peeled after a period of use.


For these already damaged floors, the owner has nothing to do. If they continue to use epoxy floors, they can only make up for them, which will not only affect the appearance but also continue to increase additional maintenance costs.However, if it is made of polished concrete, this situation will not occur. After the old ground is refurbished, the ground will look brand new, which can reach the same life as the building, and save future maintenance and maintenance costs, as long as it is cleaned daily.


Regarding the polished concrete floor, it can be said that it is a floor where the concrete floor is constantly polished and thrown into a luster. A real polished concrete floor is the grinding and polishing of the existing concrete floor with a high-power grinder with diamond grinding discs to form a very perfect concrete surface. Need to push the grinder back and forth, criss-cross grinding. After grinding with coarse dianmond metal bond discs, we replace with finer resin discs for grinding. According to the customer’s requirements for gloss, we need to replace the grinding discs with different fineness many times, up to 9 times. In any area, we can provide finishes from matte to high gloss. About halfway through the polishing process, we add Silica Hardener, a specialized liquid with chemical properties that increases the hardness and strength of the floor, tightens concrete pores, and provides more polishing area. The higher the ground strength, the higher the gloss.


Polished concrete floors are widely used in industrial plants, hypermarkets, warehousing and logistics centers, underground garages, schools, libraries, and hangars due to their advantages of being safe and environmentally friendly, easy to clean, long service life, and not peeling or damaged. and other concrete base floors.

The process of renovating old epoxy floors into polished concrete floors is also very simple.

1, the first is to remove the old epoxy.

Use a 30# metal abrasive disc to remove the epoxy layer.

2. Coarse grinding

Dry grinding with 60# diamond metal grinding disc, repeatedly grinding vertically and horizontally until the concrete surface is uniform and flat, and clean the ground dust.

3. Improve the hardness of the ground

Mix the silicon hardener 1:2 with water, and push it evenly on the ground until it is absorbed by the ground.

4. Fine grinding

Use 50#/150#/300#/500# diamond resin grinding discs in turn for dry grinding, and evenly grind vertically and horizontally. After each grinding, the scratches left by the previous grinding process disappear. Clean up dust.


5. Coloring

Thoroughly clean the ground dust and fully dry it. After the ground is completely dry, push the concrete penetrating colorant evenly away.

6,  solid color

After 24 hours of coloring, sprinkle the concrete color fixing hardener (XJ-012C) evenly on the concrete surface, and use a dust pusher to push it evenly.

7, high-speed polishing

Before the color-fixing hardener (XJ-012C) is completely dry, use a high-speed polishing machine with a 2#/3# diamond polishing pad to repeatedly grind and polish until the ground is hot and completely dry.

The polished concrete floor does not need to be maintained and maintained in the later stage, and it will always be as bright as new, as long as it is cleaned daily.
