2022-11-18
Is the cement seal curing agent floor dry or wet? For this question, the following is to introduce the respective benefits and characteristics of dry grinding and wet grinding, and then find the answer to the question.

Benefits of Wet Grinding
1, Wet grinding helps to prolong the service life of the grinding disc
When grinding medium to high hardness ground, wet grinding and wet polishing can greatly extend the service life of the grinding disc, and help to achieve the grinding effect, cutting deeper, exposing aggregates, and cutting faster.
2, Wet sanding helps to make a matte effect
The wet grinding method can use a higher mesh grinding disc to produce a relatively matte effect, and it is also convenient for daily maintenance of the ground. The first 2 or 3 polishing processes, if water grinding, can help to remove the scratch marks left by the metal grinding disc on the ground.

Benefits of Dry Grinding
1. Dry sanding helps to create a high-gloss effect
Compared with wet grinding, dry grinding is more helpful to achieve the effect of ground highlights and achieve higher reflectivity of the ground.
2. Helps to deal with soft concrete ground
The softer concrete floor consumes the grinding discs of the hard carcass, which leads to higher costs and lower returns. If it is wet-ground, the grinding discs will leave grinding marks on the ground because they are too sharp. The dry grinding method is more suitable for Soft concrete floor.

So, should the cement-cured floor be dry-ground or wet-ground?
In many cases, the ideal grinding method for cement-cured floors is often a combination of dry and wet. Usually after the wet grinding is finished, the wet polishing is done again, and then the dry polishing method is used to improve the gloss of the ground, which can control the cost and reduce the dust, because the amount of dust generated during the high-mesh polishing process in the final stage is actually very small of.
