The Activator can be applied in two different ways:
Before glueing: apply the Activator on one of the two objects/pieces you want to be glued, and wait until the spray evaporates. Apply Colle21 on the other object/piece, quickly join the surfaces and wait for the glue to dry.
After glueing: apply Colle21 super glue one of the objects/pieces join the surfaces, then spray the Activator21 on the joint and wait for the glue to dry .
Activator21 is transparent and does not leave signs on the treated surface. Use the spray 30 cm from the surface to keep it smooth. Can only be applied by using a suitable air spray valve
