How much is waterproof per square meter? I would like to ask your friends who have just finished decorating, how much is a square meter quoted by the decoration company or guerrillas? Is it 40 yuan or 50 yuan? Or a square of 60 yuan? Why do you say that? Two months ago, a friend of mine wanted to decorate the house. I was supposed to help her do it, because I got away with some concerns. We generally take an evasive attitude towards our relatives and friends. Avoiding is not because I don't want to help my friend, but because I hope my friend can still do it. There is a saying: if you have done house decoration for relatives and friends, there is a 50% chance that you won't even have friends in the end. This friend soon received many quotations, including well-known large-scale decoration companies that often advertise in major media, and many guerrillas. You can't help a friend design and construct, but it is necessary to help a friend review the quotation.
Not much to say, now just say waterproof. The first one is a well-known big company from Guangzhou. The company is located in Jiaxin Hua Ting, next to Normal University, and the waterproof price is over 70 square meters. The second company is also a leading company, with an offer of more than 60 square meters; Next, there are quotations from several unknown small companies and guerrillas: the prices range from 57 yuan, 50 yuan, 60 yuan, and so on. Next, I accompanied my friends to a contract company that often advertises in Guiyang Evening News to see the budget. The waterproof price is 65 square meters, and then I looked at the description of the process materials: using Korean international waterproof. Up to now, in the waterproof technology of many guerrillas or decoration companies, what I have seen is the use of internationally accepted waterproof materials. How can I tell you? 10 years ago, when I was a designer in a decoration company, the waterproof material used by the decoration company was this kind of international waterproof. There is also a name called Marimi, but these two names are packaged in the same package by different companies, so it is difficult to tell who is true and who is false. A pot of this stuff for about 30 yuan can be made into tens of square meters, and the cost is less than 1 yuan. Of course, you need a little cement, but you can't use half a bag of cement for waterproofing. To be clear, the cost of international waterproof materials is less than 1 yuan! Another cost is labor cost. Now the cost of waterproofing ranges from one square meter in 5 yuan to one square meter in 10 yuan. Let's calculate it as per square meter 10 yuan for the time being, then the waterproof cost of your home only needs 1 1 yuan! This is the real cost of international waterproofing! Where do these quotations of 50 yuan, 60 yuan and 70 yuan come from? As a waterproof material used for many years, people who are basically knowledgeable rarely use it again. Because better materials have been widely used, why are some companies still using them? Because of the lowest cost, you can get the biggest profit!
Now I will come back and tell my friends who want to decorate. At present, the most commonly used waterproof materials in the decoration industry are JS and K 1 1, in which JS is cement-based or simply painted with cement. K 1 1 is a prepared aqueous solution and powder for use together. In the past, we used Korea International Waterproofing the most, and the effect was passable, but recently we seldom used it, because the quality of JS and K 1 1 is more assured. JS and K 1 1 are models made of the same material, not from a certain manufacturer. Please make it clear. JS and K 1 1 are the same, and there are n manufacturers in production, and there are also n packaging brands on the market. The price is slightly different, so is the quality. I bought an unused brand, but failed the test, and finally had to turn the work over and do it again. What is the specific cost of these two materials? Let me tell you now. At present, the price of a barrel of JS is about 120 to 150 yuan, but we often buy it. It's about 18kg, almost 40kg. If you do it twice in a bucket, you can brush it to about 30 square meters. If you only do it once, you can complete a house of about 120 square meters in one barrel (this trick is loved by guerrillas). Labor cost, per square meter 10 yuan, calculated as a house of 120 square meters, uses two barrels, that is, 240 yuan, with a building area of about 70 square meters (the walls are both 2 meters high), so the cost should be: 120 * 2+70 * 10 = 940 yuan. Let's talk about another waterproof material K 1 1.
From the price point of view, K 1 1 is one grade higher than JS. Generally, the vats with good quality are all about 260 barrels, such as Gaode and Niuyuan, and the ones with poor quality will not be mentioned. This vat can only be made of 13 square meters, which is the cost of 20 yuan per square meter. With the labor cost 10 yuan, the cost is probably around 30 yuan. K 1 1 The best brand in Guiyang market should be Gaud, an Australian brand that entered China, and put up the brand of "Buy waterproof, send construction" in the market. As long as you buy his materials, he will give you the construction, and the warranty period is 10 years. It should be said that it is possible. But he wants about 320 yuan a barrel and can only make 10 to 12 square meters, which means the cost of 30 yuan is one square meter. If you are willing to use this brand, you don't need a decoration company to build it at all. Just buy it yourself and the manufacturer will build it for you.
Look what I wrote. Dear friends who want to decorate, you know how much you have to pay for waterproofing. You can calculate it yourself!
