Surface Preparation

Joints should be thoroughly cleaned, and surface should free from oil, grease, fuel, paraffin, silicone and other residues. Generally priming is not required. Primer is necessary for dusty, porous and unsound substructures. In this case PU PRIMER 200 is used, or PU PRIMER 300-2K is used for damp concretes.

APPLICATION
Place the backer rod into the joints carefully at an appropriate depth. Place the sealant into the gun and cut the nozzle from the farthest end to deliver the right bead size. Sealant must be applied into the joint. Wide joints may require more than one application with the gun in order to ensure that the sealant is in full contact with the sides and bottom of the joint. Smoothen the sealant immediately after the application.
