SB-525 Jointweld™ LD is a two component, rapid curing 1:1 ratio polyurea joint filler designed for traffic and freezer applications. It is self-leveling, 100% solids and flexible, allowing 10-15% movement of installed joint width. SB-525 is used to fill interior control joints or new construction saw joints on horizontal concrete surfaces. SB-525 is designed for industrial floor applications receiving vehicle and forklift traffic. SB-525 can be used in exterior applications, when minimal joint movement from thermal cycling will occur.
