Joint preparation  

Joint surfaces must be clean, dry, and free from any contamination. Where applicable, use a closed cell polyethylene backing rods. Use masking tape on each side of the joint in order to maintain a clean uniform finish.

Application

Puncture the top of the cartridge. Cut the nozzle at a 45o angle to the required bead size and apply the sealant using caulking gun. Extrude the sealant firmly into the joint and maintain a continuous bead. 
Tool the sealant into the joint and then remove the masking tape immediately after the application.

Application temperature is between +5oC and +40oC. Tooling time is within 15 minutes from the application at 23oC. Curing rate is 2-3 mm for each day at 23oC.
