After spraying or brushing the cement sealing curing agent, the next step is to polish the ground. Since it involves the polishing of concrete floors, it is inseparable to discuss which is better, dry grinding or wet grinding. Is the cement sealing curing agent floor dry or wet? For this question, let’s introduce the advantages and characteristics of dry grinding and wet grinding, and then find the answer to the question. Benefits of wet grinding on concrete floors
1. Wet grinding helps environmental protection.
Wet grinding is an ancient method with a long history. People have used wet grinding to grind natural stone for hundreds of years. In the early days of the polished concrete industry, people used to wet the ground. In the past decade or so, dry grinding has been a popular grinding method in the American industry. However, with the increasing environmental awareness and "green" construction requirements, wet grinding has caught up again and has become an important consideration in the bidding process.
2. Wet grinding helps reduce pneumoconiosis
Wet milling can effectively avoid silicosis (also known as silicosis, English name Silicosis, pneumoconiosis caused by long-term excessive inhalation of rock dust containing crystalline free silica) and reduce dust pollution generated during dry grinding.
3. Wet grinding helps to extend the service life of the grinding disc
When grinding the ground with medium to high hardness, wet grinding and wet polishing can greatly extend the service life of the grinding disc, and help achieve the grinding effect. The cutting is deeper, the aggregate is exposed, and the cutting speed is faster.
4. Wet grinding helps to make a matte effect
The wet grinding method can be used to make a relatively matte effect with a higher number of grinding discs, and it is also convenient for daily maintenance of the ground. The first 2 or the first 3 polishing processes can help remove the scratch marks left by the metal grinding disc on the ground if it is polished with water. The benefits of dry grinding on concrete floors
1. Dry grinding helps to make the highlight effect
Compared with wet grinding, dry grinding is more helpful to achieve the effect of high gloss on the ground and achieve higher reflectivity of the ground.
2. Helps to cope with soft concrete floors The softer concrete floor consumes the abrasive discs of the hard carcass very much, which leads to higher costs and lower profits.
Wet grinding will cause the abrasive discs to be too sharp and leave abrasion marks on the ground. Dry grinding is more suitable Soft concrete floor. So, is the cement solidified floor good for dry grinding or wet grinding?
In many cases, the ideal grinding method for cement-cured floors is often a combination of dry and wet. Usually wet polishing is done after the wet grinding, and then dry polishing is used to improve the gloss of the ground. This can control costs and reduce dust, because the amount of dust generated in the final stage of high mesh polishing is actually very small of.
