∎Direction 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.
Construction joint cutting
Use a cutting machine to cut the construction joints according to the design plan
Cleaning the Joints
The surface must be hard, dry and clean. The inside of the seam must be cleaned up by shoveling, cutting, polishing, sweeping and blowing.
Pad backer rod
Lay a polyethylene foam strip that is slightly larger than the construction joint in the construction joint, and the depth depends on the construction situation
Applying the sealant
Put the sealing glue into the glue filling equipment (seam filling machine, glue gun, duckbill pot), squeeze the sealing glue evenly and continuously, and move it evenly and slowly to ensure that the base surface to be glued fully contacts the sealing glue to prevent Move too fast and generate bubbles or holes
∎Attention of operation
●We advise reserved 2mm, otherwise, the sealants will overtop the concrete road.
Reserved gap: Since the construction joint will expand and contract with the change of temperature, the surface should be lower than the road surface after grouting, 3-4mm in summer and 1-2mm in winter.
Wear suitable protective clothing, gloves, and eye/face protection. After contact with skin, wash immediately with plenty of water and soap. In case of an accident or if you feel unwell, seek medical advice immediately.
This is professional auto glass glue, it is high viscosity ( thick ) , so a caulking gun will be required to apply the glue. If you using a regular ( not a professional ) caulking gun to apply the glue, please make sure to warm the glue up by using the hair dryer for 15 mins . Please do not stock it in cold place so the glue will freeze and very hard to apply.
∎Packing & Delivery
Wear suitable protective clothing, gloves, and eye/face protection. After contact with skin, wash immediately with plenty of water and soap. In case of an accident or if you feel unwell, seek medical advice immediately.
