Developed to address common pain points in traditional tile laying, such as leakage, hollowing, and detachment, these backboards combine innovative materials and processes to excel in waterproof performance, bonding strength, durability, and environmental friendliness. They are widely used in various architectural scenarios, providing users with reliable solutions for tile decoration.Waterproof tile backer usually adopt a multi-layer composite structure design. The inner layer is a waterproof layer, which is made of waterproof materials such as high-density polyethylene (HDPE) film and butyl rubber. The middle layer is a reinforced support layer, which is a glass fiber reinforced cement board (GRC), fiber cement pressurized board (FC) or lightweight polystyrene foam board composite structure. It can not only bear the weight but also reduce its own weight. The outermost layer is a protective coating, which is made of acrylic resin or polyurea coating, which is scratch-resistant, wear-resistant, UV-resistant and easy to clean.

If you're considering waterproof tile backer for interior decoration, you need to carefully consider its performance characteristics. Whether it's for suspended ceilings, partition walls, floors, or basements, it's essential to possess the following properties:

Waterproof

Effectively resists moisture penetration even with long-term use, making it particularly suitable for humid environments like kitchens and bathrooms, preventing mold and structural damage.

Stability

High compressive and flexural strength ensures stable shape even under long-term loads and stresses, ensuring the smoothness and firmness of subsequent decorative layers and minimizing the risk of cracking and peeling.

Fireproof

Excellent fire resistance slows the spread of fire in the event of a fire, buying valuable time for evacuation. This feature is extremely advantageous whether the waterproof tile backer is used indoors or outdoors.

Soundproofing and thermal insulation

Excellent sound insulation and thermal insulation reduce external noise interference while maintaining a stable indoor temperature, enhancing living comfort and significantly contributing to daily living.

Waterproof tile backer are suitable for public restrooms, kitchens, and corridor walls in commercial spaces such as hotels, restaurants, shopping malls, and supermarkets. They meet the stringent requirements for waterproofing, durability, and aesthetics in high-use scenarios, reducing maintenance costs and improving the quality of the space. Furthermore, waterproof tile backer are also used in public facilities such as shower rooms and pool surrounds in schools, hospitals, gymnasiums, and swimming pools. Their excellent waterproof, antibacterial, and wear-resistant properties ensure long-term, stable operation and safeguard public health.

So, what thickness should we choose for waterproof tile backer used in construction applications? A specification of 1220mm × 2440mm × 1300mm is more suitable for large-scale construction projects. Generally, a thickness of 30mm or more is preferred. 30mm-40mm is suitable for roof insulation, indoor and outdoor insulation, and basement moisture barriers where insulation is required. Thicknesses of 50mm or more are suitable for freestanding partition walls, shower walls, lockers, and benches.
