The construction methods of waterproof permeation crystallization mainly include the following three types:
Base surface treatment: Before construction, it is necessary to ensure that the base surface is clean, flat and firm. For honeycomb, uneven places, polishing should be carried out first to ensure the flatness of the base surface.
Wet base surface: Before construction, it should be ensured that the base surface is wet, but there should be no standing water. This helps the coating bond better to the substrate.
1.Brushing method: firstly, the cement-based permeable crystalline waterproof material and water are mixed with machinery according to the mass ratio of 4:1, and the viscous form is formed by stirring evenly; The prepared paint is then applied in two passes to the treated and pre-wet concrete surface. A second coat of paint can be applied while the previous coat is still wet.
2.Scraping method: the same as above, the prepared paint is evenly scraped and coated in two times.
3.Spraying method: When the poured concrete is initially set, the cement-based permeable crystalline waterproof material can be evenly sprayed on the concrete surface.
The above is the construction method of waterproof penetration crystallization, and choosing the appropriate construction method can ensure the waterproof effect to the greatest extent and ensure the quality of the project.
