1. Hard mortar, also called rigid mortar
The ratio of emulsion to mortar is 1:4. After the brushing, the coating is not required and can be directly tiled, which is more convenient. After curing, it forms a cement block and does not cause water seepage. Its back surface has good waterproof effect and is its biggest advantage. The disadvantage is that this kind of mortar has high hardness and is easy to crack with the deformation of the base layer, so it is generally used for waterproofing the back surface. Price: 200-300 yuan / barrel, a bucket of 18 kg, brush 10-13 square meters.
2. Flexible mortar
Emulsion and mortar ratio is 5:4, with elasticity, even if the base layer deformation cracking will not affect the waterproof effect. It is mostly used on the surface of water, such as wall surface and ground surface, but it cannot be used on the back surface of the top surface. If waterproof is not done well, there is water penetration and it is easy to make water seepage. Price: 300-500 yuan / barrel, a bucket of 18 kg. There is also a type of silicone-based waterproof coating in flexible mortar, which belongs to high-grade flexible mortar. The elastic tension and flexibility are good, but the price is 600 yuan/barrel, which is relatively expensive and very rare on the market.
Acrylate
Pure liquid, open cover and use. Water-based, can be melted in water, it is easy to combine with the gap in the ground to form a strong waterproof layer, waterproof effect is better than flexible mortar. After brushing, it is necessary to perform surface treatment such as pulling or sanding to increase the friction and make it easier to tiling. Due to its excellent waterproofing effect, flexible mortars and acrylates are more suitable for long-term immersion in water. Price: 300-500 yuan / barrel, a bucket of 18 kg.
4. One-component polyurethane
Indoor and outdoor use, brushing is very thick, about 3 mm or so, and the elastic tension of more than 300%, very elastic, cracking of any substrate will not make it crack, the best waterproof effect. Although the safety performance control is among the environmental protection requirements, the odor of such a waterproof coating is relatively large and it is difficult for most people to accept, and the environmental performance of very few brands is not up to the standard. Polyurethanes are colloidal and are very thick. The use of scrapers during construction is laborious and complicated. After brushing the paint, it is necessary to perform surface treatment, pull the hair or lift sand to increase the friction, and easy to tiling. Price: 500 yuan / barrel, a bucket of 18 kg.
Before brushing the waterproof coating, it is necessary to dispose of the basic layer. The application of the waterproof coating has a lot to do with the ground conditions. The more uneven the foundation, the more coating is used. Therefore, before applying the waterproof coating, it is better to simply treat the base layer and flatten the base layer as much as possible. Second, we should ensure that the ground is dust-free, soilless, and oil-free. We can carefully mop the floor with mop cloth and remove all the dust. Otherwise, it will cause cracking and peeling of the waterproof coating, which will affect the waterproof effect.
The waterproof coatings described above, the drying speed is affected by the climate, the drying speed is slower in the cold climate, but the climate has no effect on the waterproof effect. In general, mortars have a drying cycle of 24 hours and acrylics and polyurethanes have a drying cycle of 24-48 hours.

According to the type of abrasive particles: ceramic alumina VS zirconium corundum VS alumina
According to the type of abrasive selected, the flap disc can be divided into three types: ceramic alumina, zirconium corundum and alumina.
Because ceramic alumina itself has many crystals, it has good self-sharpening, relatively neat edges, good heat dissipation, and long service life. Therefore, ceramic alumina louvers are mainly used for the grinding of stainless steel, aluminum and other hard metals.
Zirconium corundum itself is a polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong resistance to high pressure and high temperature. Therefore, zirconium corundum louver blades have strong cutting ability and long service life.
Alumina: single crystal, the cutting ability begins to decline at the beginning of grinding, and the abrasive grains are not easy to break, so the alumina flap disc is suitable for the processing of common metals.
