Introduction to architectural Drywall Tape and how to paste it

The building insulation material Drywall Tape is based on fiberglass woven fabric and soaked in polymer anti-emulsion coating. As a result, it has good alkali resistance, flexibility and high tensile strength in the longitudinal and latitudinal directions, and can be widely used for thermal insulation, waterproofing, crack resistance, etc. of interior and exterior walls of buildings. The Drywall Tape is mainly made of alkali-resistant Fiberglass Cloth. It is made of medium-alkali-free Glass Fiber yarns twisted with a special organizational structure - leno tissue, and then treated with high-temperature heat setting such as alkali resistance and reinforcing agents. The main purpose of Drywall Tape is widely used in wall reinforcement materials. The method of pasting Drywall Tape:

1. A dedicated person must be responsible for preparing polymer mortar to ensure the mixing quality.
2. Open the lid of the bucket by rotating it counterclockwise, and use a stirrer or other tools to re-stir the adhesive to avoid separation of the adhesive. Stir appropriately to avoid quality problems.
3. The mixing ratio of polymer mortar is: KL binder: 425# sulfoaluminate cement: sand (use 18 Fiber Glass sieve bottom): 1:1.88:3.25 (weight ratio).
4. Weigh the cement and sand in a measuring bucket and pour them into the iron ash tank for mixing. After stirring evenly, add the binder according to the mix ratio and stir. The stirring must be even to avoid segregation and porridge-like appearance. Water can be added appropriately according to the workability.
5. Water is used for concrete.
6. Polymer mortar should be prepared as needed. It is best to use up the prepared polymer mortar within 1 hour. Polymer mortar should be placed in a cool place to avoid sunlight exposure.
7. Cut the Fiber Glass from the entire roll of Fiberglass Cloth according to the required length and width, leaving the necessary overlap length or overlap length.
8. Cut in a clean and flat place. The cutting must be accurate. The cut Fiber Glass must be rolled up. Folding and stepping are not allowed.
9. Make a reinforcement layer at the sun corner of the building. The reinforcement layer should be attached to the innermost side, 150mm on each side.
10. When applying the first coat of polymer mortar, the EPS board surface should be kept dry and harmful substances or impurities in the board cotton should be removed.
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 Fiber Glass, and the thickness should be about 2mm. Except for those with hemming requirements, polymer mortar is not allowed to be applied on the surface. Polystyrene board sides.
