In addition to the waterproofing of the house, attention should also be paid to the waterproofing of the wall surface. Water on the wall will not only lead to a beautiful appearance, but also corrosion of the wall. The penetrating waterproof coating can cause surface tiles, etc., to fall off and fall off, causing some dangerous problems. Next, the editor will explain the penetrating waterproof coating for everyone.
What is a penetrating waterproofing agent?
It is a powdery waterproof coating containing active compounds. In the presence of water, the active compounds penetrate into the concrete, forming a large number of water-insoluble long-chain crystals in the pores and cracks, filling the capillary pores, thereby Make concrete dense and waterproof. It is suitable for waterproofing and repairing the internal and external surfaces or bodies of various concrete structures that require permanent waterproofing.
Cement-based penetrating crystalline waterproofing agent has been officially put into use in China for more than ten years. Due to the complicated import channels of product masterbatch and the high price of the product market, manufacturers often consciously focus on large-scale municipal projects, such as subways, tunnels, culverts, reservoirs, etc., to ensure that funds can be returned in time. Compared with civil construction projects, there is room for product or construction prices to rise. Over time, it has formed a misunderstanding for product users. It seems that cement-based permeable crystalline waterproof materials can only be used in underground projects such as subways, and not Suitable for civil buildings. In fact, as the price of imported raw materials for such products has been declining year by year, along with manufacturers’ pursuit of product profit balance, with the implementation of national standards and the understanding and support of the design department, the application range of cement-based permeable crystalline waterproof materials has increased. The more extensive. Product characteristics of Qinglong cement-based permeable crystalline waterproofing agent
1. It has the characteristics of fast setting and early strength. After the waterproof construction is completed, other constructions can be carried out immediately;
2. It has multiple uses. In addition to waterproofing and plugging, it can also repair other concrete structural defects such as pitted surfaces and defects, and has low requirements on the base surface;
3. There is a hard waterproof conjunctiva on the base of the structure, which can produce permeable crystals that can be continuously activated inside the structure, so that it can coexist with the concrete structure and has long-lasting waterproof performance.
Scope of application of cement-based permeable crystalline waterproofing agent
1. It is suitable for the waterproof plugging of all new and old concrete and brick structure walls, roofs, kitchens, bathrooms, ground, tunnels, civil air defense projects, subways, swimming pools, sewage pools, large reservoirs and other projects;
2. It is used for the water-incoming surface or back-water surface waterproofing project, especially suitable for the waterproofing and leakage repairing projects such as roof crack dripping, bottom plate leakage, construction joint leakage, deformation joint leakage, etc.
Use method of cement-based permeable crystalline waterproofing agent
1. Base surface treatment: The dry base surface must be sprayed with water first, and the seepage point or seam must be sealed first. The new structure can be waterproofed after the curing period is over, and the old structure must Waterproof construction can only be carried out after the original waterproof layer is removed. The base surface should not have floating dust, oil stains, unevenness, damage and unevenness should be leveled and repaired.
2. Strict ingredients: ingredients according to the ratio of material: water = 4:1, stir evenly, no dry agglomerates or material balls, stir until it is viscous and start construction.
3. Construction method: use iron plate plastering method or scraper coating method, the construction thickness is generally 1.0-2.0mm, the coating above 1.5mm is constructed by plastering method, and the coating of 1.0-1.5mm is constructed by scraping. law.
4. Maintenance: The maintenance should be carried out before the initial setting, while the construction is being carried out. The maintenance adopts the method of dipping a paint brush on the surface of the scratched waterproof layer or spraying a fine mist onto the surface of the waterproof layer.
