In the renovation of the bathroom, waterproof construction can be said to be the most important work. What bathroom waterproof material? How much do you know about these waterproof materials? Below, please follow us to learn about bathroom renovation.
Also known as rigid mortar, the ratio of emulsion to mortar is 1:4. After brushing, it is not necessary to treat the coating, and it can be directly tiled, which is 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. Market price: 200-300 yuan / barrel, a bucket of 18 kg, can brush 10-13 square meters.
2, flexible mortarEmulsion 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. Market 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 about 600 yuan/barrel, which is more expensive.
3, acrylatePure 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 flooding. Market price: 300-500 yuan / barrel, a bucket of 18 kg.
4, one-component polyurethaneIndoor and outdoor use, brushing is very thick, about 3 mm or so, and the 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 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. Market price: 500 yuan / barrel, 18 kg barrel.
