Waterproof coatings are divided into four categories:
Although there are many waterproof coatings on the market and on the Internet, such as “two-component polymer waterproof coatings†and “one-component polyurethane waterproof coatingsâ€, there are many types of names, but if they are divided according to the nature, they are currently on the market. There are only 4 kinds of indoor waterproof paints for sale, and they have different performances and advantages and disadvantages.
1. Hard mortar, also called rigid mortar: The ratio of emulsion to mortar is 1:4. After brushing, it is not necessary to process the coating and it 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 flexibility, even if the base 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.
3, acrylate: pure liquid, open and use it. 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: Both indoor and outdoor use, the brush is very thick, about 3 mm or so, and the elastic tension is more than 300%. It is very elastic. The cracking of any substrate will not make it crack. The waterproof effect is best. 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.
The drying speed of these paints is affected by the weather, and the drying speed is slower in a cool 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.
"One-component" and "two-component" differences: mortars are two-component polymers, ie, they are made from emulsion and mortar; acrylates and polyurethanes are single-component without mortar.
Brush the base before painting
The application of waterproof paint has a lot to do with the condition of the ground floor. The more uneven the grass, the more paint 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.

A polycrystalline novel silicate material obtained by crystallizing glass under the action of a catalyst or a nucleating agent, is a dense, nonporous, homogeneous mixture of a crystalline phase and a residual glass phase. Generally, the size of the crystal can range from nanometer to micrometer, and the number of crystals can reach 50% to 90%. Has high mechanical strength, low electrical conductivity, high dielectric constant, good machinability, chemical resistance, thermal stability and so on. These properties depend on the type and amount of crystals, as well as the composition and properties of the remaining glass phase, and are closely related to the crystallization conditions and the like. According to different nucleation or crystallization treatment, it is divided into photosensitive and heat-sensitive glass-ceramics. Can be used to make circuit boards, charge storage tubes, screens for photomultiplier tubes, missile warheads, radomes, bearings, pumps, reactor neutron absorbing materials, insulating pillars, etc.
