First, Jinan wall waterproof construction technology 1, before bonding, first lay the roofing waterproofing membrane in advance, then roll up both ends of the roofing waterproofing membrane, pour the prepared cement glue into the primer, and scrape it with a scraper. Open it, then push the roof waterproof material forward, and use a scraper to remove the residual air in the roof waterproof film in time and scrape off the excess glue. Attach rate of ceiling waterproofing membrane and conventional layer is 85% or higher.
2. Joint approach
Waterproof roof joint construction: the joint between the additional layer and the ladder waterproof layer is more than 5 cm. The steam barrier, waterproof layer and additional layer are all together and connected with cement glue, with a width of 10cm.
The lap width of roofing waterproofing membrane is 8- 10 cm, the long side and short side are 10- 15 cm, the seams of adjacent sides must be staggered above 100 cm, and the included angle between the wall and the ground is greater than 30 cm.
3. After the protective layer is completed, the waterproof layer must be made of 2cm thick cement mortar 1: 2.5. The second layer must be staggered by more than 20 cm, and the second layer must be painted, and the protective layer must be flat. Water is maintained by sprinkling water. If it is not waterproof by sprinkling water, it is easy to break and cause bad phenomena.
2. Jinan 1 Matters needing attention in wall waterproof construction. The angles between walls and the joints between walls and floors are easily overlooked in the construction process. You should carefully sweep and clean corners or fingers with a towel. Because the house often leaks water, it is in such a small place.
2, the ground and sewer junction should also be properly handled, clean up the roots. The combination of various types of pipes and floors also requires the builder to perform these tasks during the decoration process.
3, first of all, before the waterproof project construction, all the parts that must be laid must be cleaned up. This includes removing loose parts and cleaning up debris.
The above has introduced the relevant contents of the construction process of wall waterproofing in Jinan. I hope everyone can understand that the steps of wall waterproofing are not simple.
