Answer:
(1) Next comes the function—since it’s difficult to achieve complete dryness on bathroom walls, it’s best to use water-based waterproofing materials.
(2) Weatherproof performance – Since the bathroom surface is immersed in water for many years, waterproof materials must have drainage capabilities to prevent phenomena such as cracking, peeling, and aging.
(3) Enhanced water-proofing and crack-resistant properties – Because bathroom corners and water pipes are particularly prone to leaks, waterproof materials must possess these characteristics.
(4) Surface must be fitted with functionality—Since bathroom waterproofing construction usually involves priming, tiling, or installing tiles, it must be compatible with both to avoid any potential issues with the installation.
