At present, the market management of building materials is not standardized, and there are many fake and inferior products on the market When purchasing, we should choose relatively famous brands The real environmental protection waterproof material should have ten ring certification or CTC environmental protection certification and product qualification certificate In addition, pay attention to the manufacturer's service measures when purchasing waterproof coating Generally, regular manufacturers have relatively standard pre-sale, sale and after-sale services when selling products 4 Why is it recommended to buy materials in the building materials supermarket? Generally, the products in the building materials supermarket are priced clearly, and the supply of goods is relatively regular, so the products are not easy to produce fake and inferior products In addition, disputes such as return and exchange of goods are relatively easy to solve 5 What's the cost performance of all kinds of waterproof materials? All kinds of waterproof coatings sold in the market, as long as they meet the national standards, should be used as home decoration waterproof These coatings have their own advantages, you can choose to buy according to your own needs Polyurethane waterproof coating has good elasticity and extensibility In terms of coating quality, it is the most outstanding comprehensive performance of all kinds of coatings, but the construction period is long and the price is expensive It is worth noting that most of the miscellaneous brand products sold on the market are not pure polyurethane, and their environmental protection performance is not very good; acrylic waterproof coating, which is convenient for construction, environmental protection, film performance is also relatively good, and the price is moderate, so this kind of coating will be used in general home decoration waterproof; JS is a rigid flexible waterproof coating, which is convenient for construction, environmentally friendly and non-toxic, and also a good choice; Waterproof mortar coating, with high film strength, good combination with the base, can directly paste ceramic tiles, economical and practical However, due to its rigid waterproof material, it is not suitable for the decoration of new houses with possible settlement In general, among all kinds of coatings, polyurethane is the best, acrylic and JS are the best, while mortar coating is economical and practical 6 What are the main considerations of choosing materials? First, waterproof performance, and then environmental protection performance Waterproofing is a concealed project After waterproofing, tiling is done If toxic materials are selected, it is like burying "poison gas bomb" in Canada It will release poison gas for a long time, and it is difficult to dismantle and replace Therefore, environmental protection of materials is also a very important aspect of selecting materials 7 How to buy environmental protection waterproof coating? Go to the regular building materials City (supermarket) and buy products certified by China environmental mark and CTC product environmental protection and quality certification 8 What is the simplest way to distinguish the true and false waterproof coating? First, look at the packaging, whether it meets the requirements of the outer packaging of brand products, with bright color and clear handwriting, mark the product name, net weight, explain the origin, certificate of conformity and other requirements according to the specifications Most famous brands have their own anti-counterfeiting marks Pay attention when buying 9 Purchase polymer polymer materials to avoid being fooled? At present, many of these materials are not called polyurethane, but what polymer polymer materials are called instead The real polymer polymer materials are just JS waterproof materials for short What's more, in order to confuse the audience, some manufacturers even call GS polymer materials as g-generation J, which is really hard-working The price of 20 kg / barrel of such materials is more than 20 yuan - 100 yuan, mostly selected by small decoration companies 10 How to judge the quality of waterproof materials? The following three aspects are mainly considered in the judgment of waterproof materials: (1) the coating shall be free of precipitation, stratification and caking; (2) there is no strong pungent smell; (3) whether the construction is convenient 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,
