Because of the different types of waterproof materials, the requirements for the base surface and the construction process are also different. How to make a good waterproof quality according to the geographical environment? We analyze the bathroom based on the key parts of the waterproofing.
Asphalt: Long-term volatilization of toxic substances after construction, pollution of the environment, is a product that the country has ordered to be phased out and banned.
Waterproof coating: It is a flexible material, with good extensibility, large changes in strain structure (prefabricated roof, etc.), mostly petrochemical products. Customers must spend several times more than the original to enjoy the same quality, otherwise they may buy 'Y' goods.
Mortar waterproofing agent: It is a rigid material. In terms of composition, it is divided into iron oxides, inorganic aluminum salts, silicones, and higher fatty acids. Iron oxides: The waterproof effect is unstable after construction and has been eliminated. Inorganic aluminum salts: good permeability, but acidic, corrosive to the metal, and reduce the strength of cement mortar, easily lead to cracking, is gradually being eliminated. High-grade fatty acids: With a long service life, the use of its stirring cement mortar can greatly increase the density of cement mortar, eliminate and fill, plug the tiny cracks and pores generated when the cement mortar is solidified, and make the whole mortar layer of cement. Form a permanent waterproof layer that water molecules cannot pass through, that is, as long as the cement mortar layer is not damaged, the waterproof effect will be forever. It is generally 30 years. The scope of application is wide, and it can be applied on the wet base surface. The facets of cement, brick and stone constructions need to be waterproof, impervious, and damp-proof, and they can be used on both the water front surface and the back surface. For example, bathroom, kitchen and so on.
Waterproof materials are difficult to distinguish between the authenticity and the merits of the outer packaging. They should choose brand products with high reputation, good reputation, high anti-counterfeiting, quality system, environmental protection certification, and tens of thousands of households to practice tests. Avoid and eliminate leakage problems.
