Secret 3 major types of common bathroom waterproof materials

Common bathroom waterproofing materials are mainly coiled materials (SBS elastomer modified asphalt coil, polyethylene polypropylene waterproof membrane), coatings (acrylic acid, polyurethane), etc. These different types of bathroom waterproof materials How to choose? Xiao Bian reminds you to consider the price of all materials to meet the national standards and construction according to the specifications.

First, the material cost of common waterproof membranes.

1. SBS and APP modified bitumen waterproofing membrane: This kind of waterproofing material needs to be coated with cold base oil on the base surface before construction to achieve the effect of curing the base surface and improving the bonding force. The coil material is generally applied in application. Layers, additional reinforcement layers are required in weak parts such as pipes and corners. Each coil needs to be overlapped in the horizontal and vertical directions. The shaped parts need to be cut. Generally, the amount of spreading is about 20% of the total amount. In addition, such materials are divided into I type and II type according to the thickness and various indexes. Generally, type II is better than type I. Therefore, the general I type modified asphalt waterproof coil material cost: 26 ~ 30 yuan / m2. Type II modified asphalt waterproof coiled material cost: 32 ~ 36 yuan / m2.

2, polyethylene-propylene SBS elastomer APP plastomer modified asphalt waterproof roll material waterproof tape: This type of coil is mainly classified according to the weight per square meter. Most of these waterproof materials are carried out by the enterprise, and according to the national demarcation: all products with relevant national standards, all indicators must be implemented according to the national scale, the thickness of the polyethylene film layer of polypropylene fiber produced by one molding process must be To reach the level of 0.5mm or more, it is necessary to achieve the national industry policy to reduce maintenance indicators. At present, most of the market is 250g, 300g, 400g, etc., which can not reach this index, and the cost is as low as 3~5 yuan/m2. The material cost of a single-form polyethylene polypropylene waterproofing membrane that can reach the national standard is above 28 yuan/m2.

Second, the common coating film waterproof material cost of bathroom waterproof material

1. Polymer modified cement-based waterproofing material: According to the specification, the base surface is painted twice, each layer is 1 kg/m2, for a total of 2 kg. The construction cost of waterproof materials is 20~24 yuan/m2.

2. Acrylic and polyurethane waterproof coatings: According to the specification, it is necessary to apply 3 times on the base surface to form an elastic waterproof coating film. The general dosage is as follows: the bottom layer is applied once, and the bottom layer is thin, and the dosage is about 0.5 kg/m2. The intermediate reinforcement layer needs to be laid with a glass fiber mesh cloth, and the amount is larger than the bottom coating film, which is about 0.8 kg/m2. Then apply the top layer in an amount of about 0.5 to 0.8 kg/m2. Finally, roll with a surface coating diluted with water. Therefore, it can be seen that the acrylic and polyurethane waterproof coatings are about 2 kg per square meter regardless of the single and double components. According to the current raw material situation, the cost of acrylic waterproof coatings is about 28~32 yuan/m2, and the polyurethane waterproof coating is better than acrylic acid because of its solid content and impermeability. Its cost is also 35 yuan/m2. the above.
