Elastomer modified bitumen waterproofing membrane is divided into carcass

Elastomer-modified bitumen waterproofing membrane is divided into localized wall blisters according to the carcass. It can be scraped off only partly, and the edges of the scraped part are smoothed, then primer is applied, and then painted again, if it is Large areas of bubbling must be scraped off, and construction will be carried out when the wall is dry. 　Sometimes not long after the decoration is completed, blocks of putty float and fall on the wall. The main reasons are poor construction technology, poor putty, paint adhesion and shrinkage performance. The quality of the construction process requires a professional construction team and experienced construction personnel, which reminds us to be careful when looking for a decoration company and not to be cheap.

Elastomer modified bitumen waterproofing membrane is divided into carcass according to the quality of the waterproof layer during the construction process. Acceptance: After the base layer is cleaned, the acceptance should be carried out, mainly to check whether there is dust, ash and leveling layer for hollow cracking, ground and wall Whether the corners are rounded according to the design requirements, whether the slope of the floor drain meets the design requirements, etc. The drainage slope of the floor drain is 5% within 50mm from the edge of the floor drain. The floor of the bathroom should have a slope of 1%~2% of the slope to the floor drain, and there should be no water or leakage on the floor. The lap joints of the polyethylene polypropylene fiber coil should be firmly bonded, tightly sealed, and there should be no wrinkles, warped edges and drums. The end of the defective waterproof layer such as foam should be bonded to the base layer and fixed firmly without opening.





Reference dosage: each layer/m, generally 2-3 layers are wiped. Construction on seepage surface. base surface treatment, the material preparation is the same as above. Wipe and scrape construction. If the base surface seepage is serious, firstly drill a water diversion hole at the bottom to reduce the pressure, and then construct from top to bottom. Use a dry cloth to wipe the base surface and quickly use a trowel to make the top layer of material, wait for the coating to harden (no fingerprints left by hand ) Spray it wet, but there should be no accumulation of water, and then use a trowel or scraper for the second layer of material. If the water is still leaking locally, add another layer until it does not leak, and then stop the water diversion according to the leak-stopping construction method. When loading the material, it is necessary to use a little force and back and forth several times to make it compact, and pay attention to the overlap. Reference dosage: each layer/m.


Construction of roof waterproof protection layer. 　The role of the roof protection layer is to reduce the mechanical damage of the coil caused by rain, hail erosion or other external forces, reduce sunlight radiation, can refract sunlight, reduce the temperature, and slow down the aging of the coil, thereby increasing the life of the waterproof layer. After the roof waterproof layer is completed, carefully check whether the roof leaks and accumulates water, and whether the drainage system is unblocked. During the construction of the roof protection layer, it is strictly forbidden to shovel the waterproof layer with a shovel or other tools. Construction personnel are not allowed to wear spiked shoes, etc. Product assurance with quality as the priority has enabled us to continuously strengthen the cooperative relationship with our customers, and we are striving to build a high-quality and reliable product supply chain in China's building materials industry. 　Self-adhesive waterproof membrane is a material that does not require adhesives and does not need to be heated to melt. It can be firmly bonded to the base layer by tearing off its isolation layer, which is very convenient to use. It has rubber elasticity, extensibility, adhesiveness and other functions, and can well adapt to the deformation and cracking of the base layer. Some friends have cracked roofs. Use it to achieve a good waterproof effect.





Foreign companies. 　The designer has the right to choose the products of the manufacturer and is responsible for the quality of the waterproofing project. 　Reliable product quality is the principle of material selection, the selection of waterproof materials is strong, and the selection of different projects is suitable for different projects. The base wood follows the traditional design and modern material concept, which requires traditional design and material modernization. It is generally believed that traditional design methods have experienced the test of long-term engineering practice and can guarantee the quality of waterproofing projects: the choice of modern materials is the reason The quality of the material can extend the service life longer than in the past.


SBS waterproofing membrane manufacturer, supplying Guangdong area waterproofing membrane, Shandong Yuexu Building Material Group Co., Ltd. To provide you with new price change information and industry information, if you want to know more, please pay attention to our website (), or direct national unified telephone. 　Product introduction. The main raw material of SBS elastomer modified asphalt waterproofing membrane is high-quality heavy-duty asphalt styrene-butadiene block copolymer (SBS) as modifier, high-quality polyester tire, glass fiber tire as the tire base, and both sides are covered. It is made of protective isolation and decorative materials. Except for the parapet wall and the inner corner, the coil must be fully coated. The long and short sides of the lap of the rest of the coil should not be coated with adhesive. After coating, let it stand for 20-40 minutes, and wait until the film is basically dry. After that, when the finger is not sticky, you can pave it. 　Locate, pop the reference line, and pop up the positioning line and reference line according to the coil arrangement position. 　Waterproof membrane paste. When pasting, lift up the roll material brushed with the base layer adhesive, turn it over so that the brushed side is facing down, stick one end to the location of the positioning line, and then lay it along the reference line.
