It is difficult to penetrate into the tiles.
Cement-based permeable crystalline waterproof material is difficult to penetrate into the interior of tiles in liquid state and can only penetrate through the gaps between tiles. However, in modern home decoration, the gaps between tiles are usually small or even absent, which leads to the limited penetration of cement-based materials.
It is difficult to firmly bond with ceramic tiles.
Even if a thin film layer is formed on the surface of ceramic tile, it is difficult for the thin film to be firmly combined with ceramic tile due to the smooth glaze layer on the surface of ceramic tile. In addition, this waterproof film is also easy to wear and external damage.
Merchants hype and deceive consumers.
It is not reliable to repair the unbreakable floor tiles of toilets with cement-based permeable crystalline waterproof materials. This may just be the hype of some businesses, deceiving consumers. Therefore, when choosing waterproof materials, consumers are advised to know more and choose carefully to ensure the quality and effect of waterproof projects.
