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.
