1. Construction Process

• Base treatment: The construction surface should be clean, hard and dry. Remove grease and dirt on the surface of the base, such as release agent, curing film and hydrophobic agent. 
• Filling backing material: Paste masking tape on both sides of the glue application area and fill the backing material at the same time. 
• Apply primer: Apply primer on the base to cover the base. Wait for 5 to 20 minutes for the primer to dry before applying glue.

The storage period of unopened products is 6 months from the date of production. If the storage period is exceeded, it can still be used after passing the inspection.

1. Notice

• Avoid construction when the ambient temperature is lower than 5ºC or higher than 40ºC, and the air humidity is higher than 85%. The temperature of the coated base must be higher than the dew point temperature by more than 3ºC.
• Construction cannot be carried out on wet concrete surfaces, especially on surfaces with clear water.
• The unused primer after opening the barrel should be tightly covered with the barrel lid and sealed for storage.
• The construction site should have good ventilation facilities. When construction is carried out in narrow places or places where air is not circulated, forced ventilation measures should be taken.
• Construction workers should wear work clothes, gloves and other labor protection supplies.
• Fireworks are strictly prohibited at the construction site, and fire-fighting facilities should be equipped.
