Concrete waterproofing agent
Details
| Usage |
| 1. The concrete must be dry, and its surface must be cleaned before construction. |
| 2. Protect the finished product in non-protected areas. |
| 3. Dilute the waterproofing agent with water to about 5 times. |
| 4. Apply the waterproofing agent evenly on the concrete surface to be protected with a dust pusher or roller, and apply it horizontally and staggered. Do not miss any part. For loose concrete with a large water absorption rate, the protective construction should be continuous 2 times (the second time should be applied before the previous one is completely dry). |
| 5. Naturally cure for more than 24 hours at room temperature (the curing time in low-temperature environments can be appropriately extended). |
| Precautions |
| 1. When cement is changed or new cement is added, a concrete compatibility test should be performed. |
| 2. Properly mix the ingredients according to the mix ratio, and strictly follow the construction specifications when pouring concrete. |
| 3. Like conventional concrete, it must be strengthened according to the construction specifications. |
| 4. Concrete waterproofing agent should be stored in a dry place, pay attention to moisture-proof, and the shelf life is 2 years. During the shelf life, if it is damp and agglomerated, it can still be used after grinding and sieving. |
| 5. For waterproofing agent concrete in corrosive media, when the corrosion resistance coefficient is less than 0.8, anti-corrosion measures should be taken. The surface temperature of the waterproofing agent concrete structure should not exceed 100℃, otherwise, protective measures must be taken to isolate the heat source. |
