Application

Expansion joints between many different construction materials
Movement and connection joints in floors
Indoor and outdoor applications for pedestrian and traffic areas
Joints between prefabricated construction materials
Sealing and bonding of ventilation ducts, gutters and spouts etc.
For expansion joints between pre-cast concrete panels
Meets the requirements of ISO 11600 F 25 LM

INSTRUCTIONS

Before application, be sure that joint surfaces are clean, dry and free of all contamination
Apply sealant evenly, If necessary, use masking tape and remove the tape while the sealant is still soft.
Joint width/depth ratio should be 2:1 (Table 1)
If necessary, use back up material to adjust joint depth
Sealants should adhere to only two surfaces of the joint: Use backer rods and bond breakers to facilitate.

Restrictions

Avoid application below 5 °C and above 40 °C.
Do not apply on frozen or wet surfaces or through standing water.
