Glass Fiber Mesh
Glass Fiber Mesh is based on a woven glass fiber fabric, impregnated with a polymer anti-emulsion coating. This provides excellent alkali resistance, flexibility, and high tensile strength in both the warp and weft directions. It is widely used for insulation, waterproofing, and crack resistance in building interior and exterior walls. Glass Fiber Mesh is primarily alkali-resistant. It utilizes medium-alkali-free glass fiber yarn (primarily composed of silicates, offering excellent chemical stability) twisted together in a special leno weave structure. It is then treated with a high-temperature heat setting treatment to resist alkali solutions and enhance the strength of the material.
Glass Fiber Mesh is primarily used in wall reinforcement materials such as glass fiber wall mesh, GRC wall panels, EPS interior and exterior wall insulation boards, gypsum board, waterproofing membranes, asphalt roofing, fireproof panels, and construction caulking tape.
Glass Fiber Mesh Construction Method:
1. A dedicated person must be responsible for preparing the polymer mortar to ensure mixing quality. 2. Open the bucket lid counterclockwise and re-stir the binder with a stirrer or other tool to prevent separation. Stir moderately to avoid quality problems.
3. The polymer mortar mix ratio is: KL binder: 425# sulfoaluminate cement: sand (using an 18-mesh sieve) = 1:1.88:3.25 (weight ratio).
4. Weigh the cement and sand into measuring buckets and pour them into the iron ash tank for mixing. Stir thoroughly, then add the binder according to the mix ratio and continue stirring. Stir thoroughly to avoid segregation and a porridge-like consistency. Add water as needed based on workability.
5. Water is used for concrete.
6. Polymer mortar should be prepared as needed and should be used within 1 hour. Store the prepared polymer mortar in a cool, dark place away from direct sunlight.
7. Cut pieces of fiberglass mesh from the roll to the desired length and width, allowing for any necessary overlap or overlap. 8. Cut the material in a clean, flat area, ensuring accurate cutting. The cut mesh must be rolled up and not folded or stepped on.
9. Apply reinforcement layers to the exterior corners of the building. The reinforcement layer should be attached to the inside, 150mm on each side.
10. When applying the polymer mortar, keep the EPS board surface dry and remove any harmful substances or impurities, such as cotton wool.
11. Apply a layer of polymer mortar to the surface of the polystyrene board. The area to be applied should be slightly larger than the length or width of the mesh, and the thickness should be approximately 2mm. Unless required for edge wrapping, polymer mortar should not be applied to the sides of the polystyrene board.
12. After applying the polymer mortar, place the mesh on top, with the curved side of the mesh facing the wall. Apply the mortar from the center outwards, ensuring that the mesh is embedded in the polymer mortar. The mesh should be wrinkle-free. Once the surface is dry, apply another layer of polymer mortar to a thickness of 1.0mm. The mesh should not be exposed.
13. The overlap length of the mesh fabric around the perimeter must not be less than 70mm. In cut areas, a patching mesh should be used to overlap the cut area, with the overlap length not less than 70mm.
14. A reinforcement layer should be applied around the perimeter of door and window sills, with the reinforcement mesh fabric attached to the inside. If the distance between the door and window frame and the base wall surface is greater than 50mm, the mesh fabric should be glued to the base wall. If the distance is less than 50mm, a reverse wrapping should be applied. Mesh fabric installed on large wall surfaces should be embedded in the outside of the door and window frames and glued securely.
15. At the four corners of the door and window windows, after applying the standard mesh, a 200mm x 300mm standard mesh should be added to the corners at a 90-degree angle to the bisector of the window corner and attached to the outside for reinforcement. At the inside corners, a 200mm long mesh piece with a width appropriate to the standard width of the window sill should be attached to the outside.
16. Below the first-floor window sill, to prevent damage from impact, the reinforced mesh should be installed first, followed by the standard mesh. The reinforced mesh should be butted together.
17. The construction method for installing the reinforcement layer is the same as for standard mesh.
18. The mesh to be applied to the wall should be placed over the wrapped mesh.
19. The mesh should be applied from top to bottom. During simultaneous construction, the reinforced mesh should be applied first, followed by the standard mesh.
20. After the mesh is applied, it should be protected from rain and impact. Protective measures should be taken for exterior corners, doors, and windows that are prone to impact. Anti-contamination measures should be taken at the feed opening. Any surface damage or contamination must be addressed immediately.
21. The protective layer should not be exposed to rain for 4 hours after application.
22. After the protective layer has finally set, it should be sprayed with water for curing for at least 48 hours when the average day and night temperature is above 15°C, and for at least 72 hours when it is below 15°C.
