To achieve this, each roll has a 93 mm wide overlap of bitumen waterproofing layer at one end. Additionally, the edges of the material should be folded onto walls or columns above the level of the screed to avoid rigid contact between the screed and other building structures. If necessary, the material is secured with bitumen self-adhesive tape or the bitumen overlap is secured to the wall using a heat gun to prevent shifting during screed installation. Joints between sheets of material are also sealed by softening the bitumen with a heat gun. After the screed is installed, the edge of the Shumanet-100Combi material is left on the wall (column) to a height of 100 mm. * In areas around doorways, corners, pipe outlets, internal utilities, and other interior fittings, it is necessary to provide a wrap (bypass) of Shumanet-100Combi material around these elements. Shumanet-100Combi is wrapped around the protruding element and secured along the top edge to the element being wrapped with self- adhesive bitumen tape or using a heat gun. * After laying the Shumanet-100Kombi lining material, a 60 mm thick cement-sand screed is made from M-300 grade sand concrete or ready-mixed concrete. * When installing screeds, reinforce them with metal mesh with a 50 x 50 mm mesh size and a 4 mm rod diameter. The mesh should be positioned within the screed layer no lower than 20 mm from its bottom and no higher than the screed’s centerline. The mesh should be laid with a 100 mm overlap at the joints, tied with binding wire every 200 mm. * The mortar surface is leveled using a batten. For large floor surfaces, the leveling screed is applied in sections of up to 30 m², with expansion joints required. #### 󠀁[Documents](https://uzbuild.com/en/shumanet-100combi-2/#1703053158754-6b20a25b-e7d6)󠁿 [[[Technical data sheet for Shumanet-100 Combi](https://www.acoustic.ru/data/pdf_files/Shumanet_100_kombi_tehlist.pdf) [[[Download all certificates in one archive](https://www.acoustic.ru/data/goodscatalog/goods/17/certs/ru_17.zip) #### Hygiene certificate #### 󠀁[󠀁[󠀁[󠀁[ [[[Shumanet-100 Combi.
