Product positioning and application scenarios of bathroom base linings
This product uses fully waterproof phenolic glue + end-face sealing process, which is highly waterproof, moisture-proof and non-absorbent. It is specially designed for the base layer of toilets, shower rooms and bathroom dry areas and wet areas. It solves the problems of water expansion, delamination, mildew and rot of ordinary boards. It is used for shower room floor linings, wall waterproof bases, bathroom partition base materials, bathtub bottom bedding, and sink bottom linings. It is suitable for home decoration, hotel apartment tooling, and bathroom renovation projects.
Shower room wet area floor waterproofing base
The shower area is exposed to spray water for a long time. The waterproof and airtight structure does not absorb water and expand, and the tiles are laid flat and do not bulge.
Bathroom partition waterproof lining base material
Apply primer inside the dry and wet partition walls to isolate the wall from water and moisture, and prevent wall putty and ceramic tiles from falling off.
Bathroom pipe wrap lining
The sewer pipe is coated with the base layer to resist erosion by condensate water in the pipe and will not crack or delaminate after long-term use.
Main materials for hotel fine decoration bathroom batch project
The waterproof performance is unified in batches, suitable for large-scale bathroom renovations in apartments and hotels, and reduces after-sales water seepage and repairs.

Waterproof Material and Core Performance Advantages
Uses marine-grade waterproof phenolic adhesive, with overall sealed lamination and fully sealed ends, maximizing waterproof and moisture-proof performance.
Strongly waterproof and non-absorbent, no swelling even after prolonged immersion: The phenolic waterproof adhesive layer prevents moisture penetration, showing no significant expansion or contraction when soaked in water in the shower room, and will not blister or deform.
Moisture-proof, mildew-proof, and antibacterial, keeping the bathroom environment clean in humid conditions: The dense board material has no capillary pores, making it difficult for mold to grow and preventing blackening and odors in the bathroom.
High load-bearing capacity without deformation, preventing sanitary ware sagging: The high-density laminated structure ensures that bathtubs and bathroom cabinets will not dent under long-term heavy pressure, and the board surface remains flat.
Strong adhesion for tiles and cement: The flat and dense board surface ensures a tight bond between cement mortar and waterproof membrane, eliminating the risk of hollowing and detachment.
Low formaldehyde and environmentally friendly, ensuring a safe and sealed bathroom environment: Free of irritating volatile substances, preventing harmful odors even after long-term use in a small bathroom.
The entire process is optimized around waterproofing, moisture-proofing, and anti-expansion, with multiple layers of waterproofing protection from the base material to the finished product.
High-density low-pore veneer screening
Remove loose and porous plates to reduce moisture adsorption channels and improve basic waterproofing capabilities.
Deep constant temperature drying locks moisture content
Fully discharge internal moisture, reduce the water absorption expansion coefficient of the board, and adapt to the high humidity environment of the bathroom.
Marine grade phenolic waterproof glue fully coated
Each layer of veneer is completely and evenly coated with glue to form a continuous water barrier, which will not decompose when exposed to water.
Ultra-high pressure sealed hot pressing integrated molding
The multi-layer veneer is completely compacted with no gaps inside, blocking the capillary penetration channels of moisture.
Waterproof simulated environment for health and styling
Simulates the aging of bathroom fixtures in a long-term humid environment and releases water absorption deformation stress in advance.
Double-layer waterproof sealing coating on ends
Apply double waterproof sealant to the cut section to seal the end pores of the wood that are most likely to absorb water.
Standard Specifications and Custom Bathroom Fixture Services
We maintain a standard stock of bathroom baseboards in standard sizes and thicknesses, and support custom-made irregular shapes and thickened designs.




Standard Bathroom Backing Boards in Stock: We maintain a year-round stock of commonly used specifications for residential bathrooms and small apartment bathrooms, with rapid replenishment.
Custom Thickened Heavy-Duty Versions: We customize thickened waterproof backing boards for large bathtubs, heavy-duty bathroom cabinets, and public bathhouse floors.

Bulk Supply of Whole-Building Bathrooms for Hotels and Apartments: We undertake large-scale bathroom renovation projects for high-end residential buildings and chain hotels, ensuring consistent and stable waterproofing performance.
Environmental Standards and Export Testing Qualifications:
Each batch passes water immersion swelling test, anti-mold and antibacterial test, and low-formaldehyde environmental protection test. Complete qualifications make it suitable for home decoration and export bathroom fixtures.
Water Immersion Swelling Aging Test: Continuous water immersion simulates a shower environment, and the board swelling rate is controlled within the industry's high-quality standards.
Anti-mold and Antibacterial Performance Meets Standards: Black mold is not easily grown in high-humidity, enclosed environments, and there is no odor pollution in the bathroom space.
Indoor Low-Formaldehyde Environmental Certification: Meets the environmental protection standards for home decoration interior building materials, ensuring safe use in the small space of the bathroom.
Complete Set of Export Documents: Waterproof performance report, IPPC fumigation certificate, quality inspection certificate, and certificate of origin are all provided in one stop.

Bathroom Substrate Construction and Storage Maintenance
Woodworking equipment can be used for cutting and processing in a room-temperature workshop, reducing the exposure of cut surfaces in wet areas.
Prioritize pre-processing and cutting in the workshop
Avoid cutting on-site in damp bathrooms to prevent exposed surfaces from absorbing water.
Leave expansion joints + additional waterproofing
Leave small gaps between boards and cover the entire surface with waterproof membrane for double waterproofing protection.
Store in a dry, elevated, and ventilated warehouse
Keep away from standing water and damp walls to prevent premature moisture absorption during storage.
Apply a full waterproof coating immediately after completion
Apply a waterproof coating to the entire surface after the lining boards are laid to further extend the service life of the substrate.
