The importance of waterproofing in home life is no doubt that if you want a good waterproof, picking a good waterproof coating is the key first step. However, there are various types of waterproof coatings on the market, and the terms “polymerâ€, “one-componentâ€, “water-basedâ€, and “acrylic†have caused many consumers to feel dizzy. What waterproof coatings should I use for interior decoration? How to choose waterproof coating? The reporter walked into the building materials supermarket, and asked industry insiders to explain the nature and pros and cons of the waterproof coatings currently on the market, and hoped to help consumers who purchase waterproof coatings. 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 coating†and “one-component polyurethane waterproof coatingâ€...the name is professional and there are many types, but the paint sub-category of Baianju Lishuiqiao Wall Flooring Department Guo Yanglei said that if it is divided according to the nature, there are only 4 types of indoor waterproof coatings currently on the market for sale. Their performance is different and they have their own advantages and disadvantages. After the hard mortar is brushed, it is not necessary to process the coating, and it can be directly tiled for easy construction. Mostly used for the back surface of the top surface Hard mortar, also known as rigid mortar: The ratio of emulsion to mortar is 1:4. After the brushing, the coating is not required. 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. Flexible mortar will not affect the waterproof effect even if the base layer is deformed and cracked. Mostly used for water surfaces such as walls and floors Flexible mortar: The ratio of emulsion to mortar is 5:4, and it is flexible. Even if the base layer deforms and cracks, it 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. Acrylates: pure liquids, ready to 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. One-component polyurethane: Both indoor and outdoor use, brushing is very thick, about 3 mm or so, and the elastic tension is more than 300%, very elastic, cracking of any substrate will not make it crack, 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.
