Method.
1. The ground treatment will first remove the loose parts of the bulging, peeling, cracks and other parts, and the parts below 3mm and the oily parts should be brushed. After ground treatment, wash with a water gun to fully moisten the working surface until there is no more water seepage.
2. Add water to the stirring material: mix the material with water and stir, stir evenly when stirring, and the stirring time should be about 3 minutes, not too long, to prevent solidification in the mixing barrel.
3. Repair pavement for the repair of small potholes, hemp surface, peeling, exposed, fine cracks, etc., pour the stirred material on the working surface, and flatten it with a larger trowel, and do not wipe the surface twice. The initial setting time of the material is short, and there will be adhesion during the initial setting, which is not conducive to smoothing, so first use a scraper to pave a large area and then use an iron trowel to level and collect the light.

The solution to sanding on cement floors is the use of penetrants.
The penetration agent is also relatively cheap, you can buy the penetrant directly on the Internet, but the smell of the penetrant is very large, and it will emit an unpleasant smell if you use it more.
If the cement floor is sanded, you can use the BW201 floor penetrant of Bangwei Building Materials to repair, and the repair method is also very simple, you only need to spray the penetrant on the cement floor, and wait until it is dry. However, when using floor penetrant, you must remember to wear a mask, the smell of floor penetrant is very unpleasant, and it also has a certain harm to the human body, so you must remember to open the window for ventilation in the later stage, and it is best not to walk around within half a month.
Introduction of cement
Cement is a powdered hydraulic inorganic cementitious material, the main raw material is lime or calcium silicate. Cement, also known as ocean ash, red wool ash, etc., is usually not used alone, but is often used to join with sand and gravel to form mortar or concrete. After the cement is mixed with water to form a slurry, it can be hardened in air or water, and can firmly cement sand, stone and other materials together.
Cement is widely used in civil construction, water conservancy, national defense and other projects.
Cement is divided into general cement, special cement and characteristic cement according to its use and performance; According to the name of its main hydraulic imitation beam substance, it is divided into Portland cement, aluminate cement, iron-aluminate cement, phosphate cement, etc.; According to the main technical characteristics, it is divided into hydraulic hardness, heat of hydration, sulfate resistance, swelling and high heat resistance.

The sanding treatment method of cement floor is as follows:
Tools Raw materials: brushes, fine hair brooms, small and pure portable spray guns, pavement repair materials, mixing buckets, electric drill mixers, large spatulas, small putty shovels and other tools and materials.
1. Before repairing, check the sand on the road surface and prepare the required materials.
2. Use a brush and a fine broom to clean up the dust and debris on the surface of the base layer until the surface layer is exposed. After that, rinse it with a large amount of water, and then use a small portable spray gun to carefully rinse it to ensure that the base layer is free of any floating ash and debris, which can make the cement pavement more durable and stable.
3. This step is very important, first use a fine hair broom to sweep out the visible water on the base layer, and then let the surface of the base layer soak for about 20 minutes, which can make the road surface more active. Note that there should be no open water on the surface of the base cherry tree to avoid affecting the stability and adhesion of the material.
4. Pour the prepared repair materials into the mixing barrel, add 4kg of water to each bag, and then use the electric drill mixer for more than a minute until it is completely uniform and free of particles. Note that when stirring, you must stir sufficiently, otherwise it is easy to have problems such as particles.
5. Yuyun Cong poured the stirred materials into the pavement base, immediately paved it quickly with a large spatula, and then scraped it with a small putty shovel to make the surface of the base layer more flat. In addition, after the application is completed, it is necessary to carry out watering and maintenance within a day, and during this period, it is necessary to do a good job of marking, and no pedestrians or vehicles should pass through, which will affect the aesthetics and flatness of the road surface.
The cost of cement floor is low, and many roads and factories will lay cement floors, but the cement floor is prone to problems such as sand and peeling in the later stage, which affects the service life of the ground. So how to repair and maintain the situation of sand on the cement floor? Next, I will briefly introduce to you how to deal with the sand on the cement floor. >>>More
When the old cement floor is renovated, the ground is first polished with a grinder, the surface is polished and smoothed, and the concrete aggregate is removed. For the renovation of old cement and old epoxy flooring, you can use Runyu new material flooring.
Treatment method of moisture return on the cement floor: after the cracks and hollow drums are partially treated, the surface layer should be fully damp-proof and sealed. The principle of treatment is to block the capillary seepage channel in cement mortar or concrete. Generally, the method of applying waterproof paint or waterproofing agent can be used.
Tools: mortar mixer or manual mixing tools, high-pressure water washing equipment, bottom cleaning tools, sponges or mops (for absorbing excess water), more than two iron mixing buckets, and several trowels. >>>More
1. Coat concrete reinforcing agent.
This method is more suitable for the cement floor with a relatively light degree of sanding, and the problem of sand and ash on the cement floor can be solved by brushing on the cement floor with concrete reinforcing agent. >>>More
