1. The preparation of polymer mortar must be handled by a dedicated person to ensure the mixing quality.
2. Turn the lid of the bucket counterclockwise to open it, and use a blender or other tools to re-mix the adhesive to avoid separation of the adhesive. Mix properly to avoid quality problems.
3. The mixing ratio of polymer mortar is: KL binder: 425 # sulfoaluminate cement: sand (with 18 mesh sieve bottom): = 1: 1.88: 3.25 (weight ratio).
4. Weigh the bucket of cement and sand, pour it into the iron ash tank for mixing, mix it evenly, add the binder according to the mixing ratio, and stir. The mixing must be uniform to avoid segregation and appear porridge-like. Water can be added according to the workability.
5. Water is used for concrete.
6. The polymer mortar should be prepared with the use. The prepared polymer mortar should be used up within 1 hour. The polymer mortar should be placed in a cool place to avoid direct sunlight.
7. Cut the mesh from the whole roll of fiberglass mesh according to the required length and width in advance, leaving the necessary overlap length or the length of the overlapping part.
8. Cut it in a clean and flat place. The blanking must be accurate. The cut mesh must be rolled up, not allowed to be folded, or trampled.
9. Strengthen the layer at the corner of the building, 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 from the board cotton.
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 cloth, and the thickness should be about 2mm uniformly. Except for those with edging requirements, polymer mortar is not allowed to be coated on Polystyrene board side.
12. After scraping the polymer mortar, the net should be placed on it, the curved surface of the net cloth facing the wall, and spread from the center to the surroundings, so that the net cloth is embedded in the polymer mortar, the net cloth should not be wrinkled, After the surface is dry, apply a layer of polymer mortar on it with a thickness of 1.0mm, and the mesh should not be exposed.
13. The lap length around the mesh should not be less than 70mm. At the cut-off part, the lap length should be supplemented with a lap length not less than 70mm.
14. Reinforcement layer should be made around the door and window bladder. The reinforcement layer should be pasted to the innermost side. If the distance between the door and window frame skin and the surface of the base wall is greater than 50mm, the grid cloth should be pasted to the base wall. If it is less than 50mm, it needs to be turned over. The grid cloth laid on the large wall surface should be embedded in the outside of the door and window frame and adhered firmly.
15. At the four corners of the door and window, after the standard mesh is applied, then add a 200mm × 300mm standard mesh to the four corners of the door and window, and place it at a 90-degree angle to the bisector of the window corner, and paste it on the outermost side for reinforcement; A piece of mesh with a length of 200 mm and a width suitable for the width of the window bladder is attached to the female corner, and it is attached to the outermost side.
16. Below the first floor window sill, in order to prevent the damage caused by the impact, the reinforced mesh cloth should be placed first, and then the standard mesh cloth. Strengthen the grid to deal with the connection.
17. The construction method of the reinforcement layer is the same as the standard mesh.
18. The grid cloth pasted on the wall should be overlaid on the overturned grid cloth.
19. Apply the mesh fabric from top to bottom, and apply the reinforced mesh fabric first in the simultaneous construction, then make the standard mesh fabric
20. After the net cloth is glued, it should be protected from rain scouring or impacting, and it is easy to collide with the sun. The doors and windows should take protective measures, and the feeding port should take anti-pollution measures. Surface damage or pollution must be dealt with immediately.
21. The protective layer shall not be exposed to rain within 4 hours after construction.
22. After the protective layer is finally set, spray water for curing in time. The average day and night temperature should be no less than 48 hours when it is higher than 15 ℃, and no less than 72 hours when it is lower than 15 ℃.
