Want a good waterproof, pick a good waterproof coating is the key first step. However, there are many kinds of waterproof coatings on the market. What are the terms such as 'polymer', 'single component', 'water', and 'acrylate' have caused many consumers to feel dizzy. What waterproof coatings should Xiamen use for interior decoration? How to choose waterproof coating? Industry insiders explained the nature and pros and cons of the waterproof coatings currently on the market, and hoped to help consumers purchase waterproof coatings.
Hard mortar, also known as rigid mortar emulsion and mortar ratio of 1:4, after the brush does not need to deal with the coating, can be directly tile, more convenient. After solidification, it forms a cement block, which 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, can 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 wall surface and ground surface, such as the flexible mortar emulsion and mortar ratio is 5:4, with flexibility, 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.
Acrylic pure liquid, 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 flooding. Price: 300-500 yuan / barrel, a bucket of 18 kg.
One-component polyurethane is used both indoors and outdoors. The brush is very thick, about 3mm, 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 the 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 a 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.
'One-component', 'two-component' differences: mortars are two-component polymers, that is, by the emulsion and mortar ratio; acrylic and polyurethane without mortar ratio, is a single component.
