Introduction to the use of Fiberglass Mesh
1. The preparation of polymer mortar must be responsible for ensuring the quality of mixing.
2. Rotate the barrel lid counterclockwise and open it, use a blender or other tools to re-stir the binder to avoid the separation of the binder, and stir moderately to avoid quality problems.
3. The mixing ratio of polymer mortar is: KL binder: 425# thioaluminate cement: sand (with 18 mesh sieve bottom): =1:1.88:3.25 (weight ratio).
4. After weighing the cement and sand barrel, pour it into the iron ash tank for mixing, stir evenly and add the binder according to the matching ratio to stir, the mixing must be uniform to avoid segregation, porridge-like. Water can be added appropriately according to the ease of use.
5. Water is water for concrete.
6. The polymer mortar should be used with use, and the prepared polymer mortar should be used up within 1 hour. Polymer mortar should be placed in a cool place away from sunlight.
7. Cut the mesh from the whole roll of glass fiber mesh according to the length and width required in advance, leaving the necessary lap length or the length of the overlapping part.
8. Cut in a clean and flat place, the cutting material must be accurate, the cut mesh must be rolled up, not allowed to fold, not allowed to step on.
9. Make a reinforcement layer at the sunny corner of the building, and the reinforcement layer should be attached to the innermost side, 150mm on each side.
10. When applying the first polymer mortar, the EPS board surface should be kept dry to remove harmful substances or impurities on the board surface.
11. Scrape a layer of polymer mortar on the surface of the polystyrene board, the scraped area should be slightly larger than the length or width of the mesh, the thickness should be consistent about 2mm, except for those with hemming requirements, the polymer mortar is not allowed to be coated on the side of the polyphenylene board.
12. After scraping the polymer mortar, the mesh should be arranged on it, the curved side of the mesh is facing the wall, and the mesh is smoothed from the center to the surroundings, so that the mesh is embedded in the polymer mortar, the mesh should not be wrinkled, and after the surface is dry, a layer of polymer mortar should be applied on it, the thickness is 1.0mm, and the mesh should not be exposed.
13. The lap length around the High Wearing Feature Fiberglass Mesh shall not be less than 70mm, and in the cut part, the mesh lap should be used, and the lap length shall not be less than 70mm.
14. The surrounding of the doors and windows should be made of a reinforcement layer, and the reinforcement layer mesh cloth should be attached to the innermost side. If the distance between the outer skin of the door and window frame and the surface of the base wall is greater than 50mm, the High Wearing Feature Fiberglass Mesh is pasted with the base wall. If it is less than 50mm, it needs to be turned over. The mesh cloth laid on the large wall should be embedded in the outside of the door and window frame.
15. At the four corners of the door and window, after the standard net is applied, a 200mm×300mm standard net is added to the four corners of the door and window, and it is placed at a 90-degree angle to the bisecting line of the window corner, and pasted on the outermost side to strengthen; Cover the shady corner with a 200mm long mesh with a standard width suitable for the width of the window and stick it on the outermost side.
16. Below the window sill on the first floor, in order to prevent damage caused by impact, the reinforced mesh should be placed first, and then the standard High Wearing Feature Fiberglass Mesh should be placed. Strengthen mesh cloth docking.
17. The construction method for placing the reinforcement layer is the same as that of the standard mesh fabric.
18. The High Quality Fiberglass Mesh pasted on the wall should be covered with the mesh cloth of the flip bag.
19. The High Wearing Feature Fiberglass Mesh is wiped from top to bottom, and the reinforced mesh is applied first for synchronous construction, and then the standard mesh is made
20. After the Construction Wall Reinforceme Fiberglass Meshnt is glued, it should be prevented from rain washing or impact, easy to collide with the sun angle, doors and windows should take protective measures, the feeding mouth part should take pollution prevention measures, surface damage or pollution must be dealt with immediately.
21. After construction, the protective layer cannot be rained within 4 hours.
22. After the final coagulation of the protective layer, timely water spray maintenance, the average temperature of day and night shall not be less than 48 hours when it is higher than 15 °C, and not less than 72 hours when it is lower than 15 °C.
