∎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.
● Avoid contact with eyes and skin. If contact with your skin, scrub first with soap water or alcohol, then rinse with water. If contact with your eyes, rinse with plenty of water, and seek medical treatment immediately.
● It is forbidden to build on the surface of the wet substrate.
●Transportation: Avoid damp, high temperature,isolation and rain, far away from heat, handle with care and prohibit extrusion collision.
● Tools Cleaning : It can be soaked in toluene or xylene. It is strictly forbidden to immerse in alcohol and other alcohol solvents.If it is not used for a long time, it should be cleaned immediately with alcohol or other organic solvents. The cured glue can only be scraped or torn off.
∎Transport &Storage
