Of course not. Fully waterproof means the board itself is waterproof, but joints, which are major leak channels, must be properly sealed. 100% waterproof tile backer board, driven by the vision of bringing green, energy-saving, and safe experiences to every corner of the world, has set a global benchmark for green building through continuous technological innovation, strict quality management, and professional customer service, becoming a shining star in the waterproofing industry.
Waterproof XPS board coated with a polymer nano-quartz coating creates a 100% waterproof tile backer board, effectively resisting moisture penetration. Even in high humidity or direct water contact, it maintains a dry and stable surface, preventing structural damage and extending the lifespan of the building.
The closed-cell core's self-waterproofing combined with the dense, waterproof nano-coating creates a dual waterproof structure that effectively achieves zero moisture penetration. The closed-cell structure of XPS panels has no interconnected pores, preventing moisture from penetrating the core through capillary action. Even after prolonged immersion in water, the core remains dry and does not soften or deform due to water absorption. Even "gaseous moisture" such as soil moisture and condensed water in the air cannot penetrate the XPS closed-cell structure. The XPS core also has a low linear expansion coefficient, minimizing deformation during drastic temperature and humidity fluctuations. This structural expansion and contraction prevents cracking of the coating and waterproofing failure.
The waterproof performance of 100% waterproof tile backer board is more than just theoretical promise. It effectively addresses the pain points of various high-humidity environments, particularly shower areas, swimming pools, and basements, playing a crucial role.
100% waterproof tile backer board features high strength and crack resistance, easy cutting without dust, and strong adhesion. Below is a detailed introduction:
High-quality tile backing has a flexural strength of >=15MPa. If you're unsure of this value, drop a 1kg steel ball from a height of 1m and you'll find no cracks on the backing. It's primarily suitable for areas with large temperature differences, especially for renovations of older homes.
Traditional waterproof base layers require a specialized saw to cut, generating significant dust that pollutes the environment and can damage the environment. While it can affect the health of construction workers and require time to clean, 100% waterproof tile backer board are cut using laser cutting technology, resulting in smooth, burr-free edges and over 80% reduction in dust during cutting, perfectly meeting environmentally friendly construction requirements.
Compared to ordinary backings, 100% waterproof tile backer board offer 30%-50% greater bonding strength. When used with specialized adhesive, even better results are achieved. Our testing has shown no hollowing in bathroom floor tiles for five years, earning widespread user recognition.
