Waterproofing Fiberglass Mesh

Waterproofing fiberglass mesh is a thin, high-tensile fiberglass fabric coated with waterproof-compatible materials. It is widely used for reinforcing waterproofing layers in wet areas such as bathrooms, balconies, kitchens, and rooftops. This fiberglass mesh for waterproofing improves crack resistance, enhances coating adhesion, and ensures long-term moisture protection.

Product MOQ

Please note our minimum order quantity of Fiberglass mesh. For the conventional Fiberglass mesh in stock, there is no MOQ. For customized Fiberglass mesh, the MOQ needs to be confirmed according to the actual situation because the customized requirements are different.

Main applications

1. Exterior Wall Coating Systems
Waterproofing fiberglass mesh is commonly applied beneath exterior wall coatings to reinforce the base layer and prevent cracking caused by shrinkage or environmental stress. It enhances the adhesion between render, mortar, and concrete, making it essential in both new construction and façade renovation.

2. Roofing and Balcony Waterproofing
In flat roof and balcony systems, fiberglass mesh improves the tensile strength of waterproof membranes and resists thermal movement and weather-induced cracking. It extends the lifespan of bitumen, acrylic, or cementitious waterproofing coatings in exposed outdoor settings.

3. Wet Area Reinforcement in Bathrooms and Kitchens
This mesh is ideal for use behind tiles, cement boards, and other substrates in moisture-prone areas such as bathrooms, kitchens, and showers. It stabilizes waterproofing layers and prevents water vapor penetration, protecting interior walls and subfloors.

4. Plaster and Skim Coat Reinforcement
Fiberglass mesh is frequently embedded in skim coats and plaster systems to enhance crack resistance. In waterproofing applications, it ensures a stable and durable finish, especially for surfaces exposed to humidity or moisture fluctuation.

5. Below-Grade and Floor Waterproofing
In underground structures such as basements, tunnels, and foundations, waterproofing fiberglass mesh strengthens the integrity of waterproof coatings. It increases resistance to hydrostatic pressure and minimizes membrane failure under structural movement.

6. Tile and Mosaic Backing Reinforcement
Thin fiberglass mesh is laminated to the back of tiles, mosaics, or natural stone to prevent chipping and cracking during transport and installation. It ensures even bonding on walls and floors while improving handling efficiency for installers.

Features

1. Excellent Alkali Resistance – Extends Waterproof System Lifespan
Made from alkali-resistant E-glass fibers with high-performance coating, this mesh withstands prolonged exposure to cement and mortar without degradation or cracking. It significantly enhances the durability of waterproofing layers, reducing maintenance and repair costs for buyers.

2. Enhanced Crack Resistance – Minimizes Leakage Risks
The fiberglass mesh effectively distributes substrate stress, preventing cracks caused by thermal expansion, contraction, or structural movement. Ideal for wet and vulnerable areas such as bathrooms, balconies, roofs, and basements, it ensures reliable waterproof protection.

3. Lightweight and Flexible – Accelerates Installation and Saves Labor Costs
Its thin and flexible structure allows easy cutting and installation using various methods (spraying, troweling, embedding), greatly improving work efficiency on large-scale projects and reducing labor and time expenses.

4. High Tensile Strength – Reliable on Complex Structures
Coated for enhanced strength and shape retention, the mesh adheres tightly even on corners, edges, and pipe penetrations, reinforcing overall structural stability and helping buyers achieve higher quality workmanship.

5. Wide Compatibility with Waterproofing Materials – Enhances System Versatility
Compatible with polymer-based waterproof coatings (such as JS and acrylics), cementitious coatings, and liquid membranes, the mesh reduces the risk of material incompatibility and rework, simplifying procurement and application.

6. Customizable Specifications – Meets Diverse Project Requirements
Available in various weights (45gsm to 160gsm), mesh sizes (4×4mm to 10×10mm), colors, and packaging options to accommodate different applications including exterior walls, tile backings, and waterproof leveling layers, providing buyers with flexible supply solutions.
