∎Directions for Use
● Cleaning:The substrate surface must be solid, dry and be clean.Such as no dust, grease, asphalt, tar, paint, wax, rust, water repellent, curing agent, isolating agent and film. Surface cleaning can be dealt with by removing, cutting, grinding, cleaning, blowing, and so on.
● Operation:Put the sealant into the operating tool,then injecting it into the gap.
● Reservation gap:The construction joint will expand as the temperature change,so the surface of the sealant should be lower than 2mm of the pavement after construction.
● About maintenance time: At the standard state, the maintenance time is about 5 hours. It depends on the actual construction conditions. The standard state is that the temperature is 23±2℃,and the humidity is 55 ± 5%RH.
● Operation Methods: Because the packing is different, the construction methods and tools are slightly different. The specific construction method.
∎Attention of operation
● Don’t mix alcohol into the product, it will cause the product invalid. The tools with the alcohol can’t be used before cleaning well.
