under the hat is a pure white face; when applied to the wall, they all show delicate skin I have always lacked the brain cells to understand the essence of this kind of paint Please help me check it I don't have the habit of "not seeking the best, but seeking the most expensive" Just introduce a good quality and cheap one Putty is an important base material of paint, which directly affects the quality of wall painting, so it should be paid enough attention to In principle, it's hard to say which coating is cost-effective when you buy what you need The key is your own needs At present, most of the properties of coatings are focused on scrub resistance, mildew resistance, antibacterial, covering small cracks and so on The price of coatings also increases with the increase of functions Before you buy, think about what you need The most expensive one is not necessarily useful to you For example, some scrubbing times can reach 20000 times, and some 3000 times The price of the former is naturally much more expensive However, according to the national regulations, as long as the number of scrubbing times reaches 1000 times, it is qualified, so the choice depends on your own needs For example, some houses are sunny and well ventilated, so the money of mildew proof function is unnecessary to be wasted Principle 2: do not trust the advertisement to get rid of the fog of the coating advertisement, and directly ask for the relevant testing methods, testing standards and authoritative testing institutions to verify the authenticity For example, the so-called nano coating is not worthy of the name, and there is no internationally recognized test standard Principle 3: open your hand and buy domestic products At present, imported coatings account for about 45% of our coatings market, and mainly occupy our high and medium-grade market Their prices are 20% - 50% more expensive than domestic coatings However, the test results of the comparative test of 10 Chinese and foreign paint brands published by the national chemical building materials testing center in 2003 show that the quality of Fuya, Jiabaoli, qiancaihua and other brands is comparable to that of foreign brands such as Libang and Dulux Five tips for on-site purchase: the heaviest one is to lift up the paint bucket and shake it If there is a loud noise, it means that the package is seriously insufficient, short of weight, and the viscosity is too low The real materials of regular large factories can hardly be heard in a flash Buy the least consumption to consult the merchants about the painting times and painting area, calculate the consumption and material cost per square meter, not be deceived by the unit price of each group (barrel), the low unit price often consumes a large amount, which is more expensive and wasteful after careful calculation, and the quality effect is poor To buy products with high quality and strong professional matching are often more professional, and provide technical guidance and after-sales services, including pre-sales consultation, construction guidance and suggestions during sales, after-sales maintenance, etc., and regular manufacturers provide colorful sample colors There are clear trademarks, place of origin, contact number, net weight, enterprise commitment standard, etc on the package of genuine paint with complete information, and its website can be opened, while the miscellaneous paint is often marked with false address, telephone and website The trustworthy enterprises that buy "trustworthy enterprises" shall be directly purchased and reviewed by government agencies from the market, and will be listed only if there is no complaint in the whole year The first problem is that there are too many undercurrents in the coating industry There are more than 8000 registered enterprises in China, and those without registration cannot be counted The whole industry is in chaos, with different brands In the industry, because of a project on the establishment of a paint factory, home decoration companies run their own factories, such things are common First, these factories are not registered in the industrial and commercial departments, not registered in the Ministry of construction, and cannot be monitored at all; second, the products are not subject to inspection and supervision The coating produced in this way, let alone environmental protection, may not even meet the minimum technical indicators Consumers must be careful not to buy products of unknown companies because they want to be cheap The other is putty Putty, as an important base material attached to the wall, filling and leveling the wall, connecting the wall and coating, its quality problem seems to have not attracted everyone's attention In fact, a lot of wall problems are caused by putty If you think about it, a big bag of putty on the stall is only seven or eight yuan, can there be any quality problems? A lot of poor putty is actually white ash, which is easy to crack and peel Because of poor adhesion, some putty will be mixed with 107 glue which has been expressly forbidden to be used This kind of glue is not waterproof, will soften when encountering water, and will volatilize polluting gas formaldehyde 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,
