Common knowledge of coating: waterproof coating is favored. There is a good way to distinguish quality experts

Core tip: waterproof coating is favored by many fields for its excellent protective performance There are many kinds of waterproof coating in the market, such as two-component polymer waterproof coating, one component polyurethane waterproof coating and so on But how to choose high quality waterproof coating, I believe it will become a problem for many consumers In fact, according to the nature, the waterproof coatings on sale in the market can be divided into four types, with different performance and advantages and disadvantages Hard mortar: good waterproof effect of coating back surface Hard mortar, also known as rigid mortar: the ratio of emulsion to mortar is 1:4 After coating, no coating is needed Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: waterproof coating with its excellent protective performance and get the favor of many fields There are many kinds of waterproof coating in the market, such as two-component polymer waterproof coating, one component polyurethane waterproof coating and so on But how to choose high quality waterproof coating, I believe it will become a problem for many consumers In fact, according to the nature, the waterproof coatings on sale in the market can be divided into four types, with different performance and advantages and disadvantages Hard mortar: a hard mortar with good waterproofing effect on the back surface of the coating, also known as rigid mortar: the ratio of emulsion to mortar is 1:4, and no need to coat the coating after finishing After solidifying, the cement block will not leak, and its back water surface has good waterproof effect, which 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 course, so it is generally used for the waterproof of the back water surface Price: 200-300 yuan / barrel, 18kg / barrel, brush 10-13m2 Flexible mortar: cracking also does not affect waterproof effect Flexible mortar: the ratio of emulsion to mortar is 5:4, which is elastic, even if the base is deformed and cracked, it will not affect the waterproof effect It is mainly used for facing water surface such as wall and ground, but not for back water surface such as top surface If the waterproof is not well done, there is water penetration, and it is easy to pack water Price: 300-500 yuan / barrel, 18kg / barrel There is also a kind of silica gel waterproof coating in the flexible mortar, which belongs to the high-grade flexible mortar It has good elasticity and flexibility, but the price is 600 yuan / barrel, which is relatively expensive and rare in the market Acrylates: long time immersion does not affect the function of acrylates: pure liquid, ready to use It is water-based and can be melted in water It is easy to combine with the ground gap to form a solid waterproof layer The waterproof effect is better than the flexible mortar After brushing, the surface treatment such as roughening or sand lifting is required to increase the friction and easy tiling Due to the good waterproof effect, flexible mortar and acrylate are more suitable for long-term immersion environment Price: 300-500 yuan / barrel, 18kg / barrel One component polyurethane: good elasticity, one component polyurethane for both indoor and outdoor use: it can be used both indoor and outdoor, very thick after brushing, about 3 mm, and the elastic tension is more than 300%, very elastic, no cracking of any base material will make it crack, with the best waterproof effect Although the safety performance is controlled in the list of environmental protection requirements, the smell of this waterproof coating is large, which is difficult for ordinary people to accept, and the environmental protection performance of very few brands is not up to standard Polyurethane is colloidal and thick Scraper is needed in construction It is very hard and complex After painting, surface treatment, roughening or sanding are required to increase the friction and easy tiling Price: about 500 yuan / barrel, 18kg / barrel Common sense of waterproof coating: different in nature, different in waterproof coating, the difference between "single component" and "two components" is that mortar is made of two component polymers, that is, emulsion and mortar, and acrylate and polyurethane are not used as mortar In addition, the drying speed of these coatings is affected by the climate The drying speed is relatively slow in the cold climate, but the climate has no effect on the waterproof effect Generally, the drying cycle of mortar is 24 hours, and that of acrylate and polyurethane is 24-48 hours Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
