Bulked Yarn Fiberglass Mesh
Bulked Yarn Fiberglass Mesh is a high-performance reinforcement fabric woven from specially processed fiberglass bulked yarn. It delivers superior bonding strength, conformability, and positioning characteristics, making it an ideal choice for demanding reinforcement applications.
Product Information
GALAXYFIBER alkali-resistant fiberglass mesh is made from alkali-resistant fiberglass yarn treated with a special coating. It offers excellent adhesion and compatibility with acrylic, polyurethane, cement-based, and asphalt-based waterproofing materials, making it suitable for waterproofing projects such as roofs, basements, bathrooms, swimming pools, and exterior walls.
Key Features for Mosaic Tile Applications
- Crack Prevention – Effectively resists cracking caused by substrate movement and thermal stress.
- High Tensile Strength – Provides reliable reinforcement for waterproof layers under stress.
- Excellent Adhesion – Bonds strongly with acrylic, polyurethane, cementitious, and bituminous coatings.
- Alkali-Resistant Coating – Ensures durability in cementitious environments.
- Flexible & Conformable – Adapts to complex shapes, corners, and curved surfaces.
- Lightweight – Minimal added weight to waterproofing systems.
- Weather Resistant – Withstands UV, temperature cycling, and moisture.
- Cost-Effective – Reduces maintenance and re-waterproofing frequency.

Products Application Scenarios




Usage Precautions
- Storage: Store in a dry, ventilated area away from direct sunlight and moisture.
- Temperature: Do not apply below 5°C; adhesive properties may be affected.
- Surface Prep: Ensure substrate is clean, dry, and free of dust, oil, or loose particles.
- Cutting: Use sharp scissors or a cutter; do not tear by hand to avoid fraying.
- Embedding: Must be fully embedded in mortar or resin; do not leave exposed.
- Overlap: Maintain minimum 10cm overlap between adjacent strips.
- Skin Contact: Wear gloves and long sleeves to prevent fiber irritation.
Product Components
Fiberglass Bulked Yarn – The core reinforcement element, woven into a mesh structure.
Alkali-Resistant Coating – Polymer emulsion applied to protect fibers from alkaline degradation.
Mesh Structure – Leno weave pattern providing dimensional stability and strength.
Roll Core – Paper or plastic core for winding and dispensing.
Packaging Film – PE shrink film for moisture protection.
Quality Control

Raw Material Inspection – Verify glass fiber yarn linear density, tensile strength, and alkali content.
In-Process Monitoring – Check mesh size, weave uniformity, and coating weight during production.
Tensile Strength Testing – Warp and weft tensile strength tested per GB/T 7689.5 / ISO 4606.
Alkali Resistance Testing – Strength retention verified after 28 days in Ca(OH)₂ solution.
Elongation Testing – Elongation at break verified within 3–5% range.
Visual Inspection – Surface defects, color consistency, and edge quality checked.
Final Batch Testing – Each batch tested before shipment with reports available upon request.

Product Usage
- Surface Preparation – Clean the substrate; ensure it is dry, dust-free, and level.
- Apply Base Coat – Spread a uniform layer of mortar or adhesive (approx. 2–3mm).
- Lay Mesh – Press the bulked yarn mesh into the wet mortar, ensuring full contact.
- Overlap – Overlap adjacent strips by at least 10cm; 15–20cm at corners.
- Apply Top Coat – Cover with a second layer of mortar, fully embedding the mesh.
- Smooth – Use a trowel to remove air bubbles and ensure even coverage.
- Cure – Allow to dry according to the mortar manufacturer's instructions.
- Finish – Apply decorative coating or tile as required.
