To ensure positive adhesion, make sure the surfaces to be joined are clean and free of dirt and foreign material.  Cut the smallest opening possible in spout (just large enough so adhesive so adhesive can flow easily when gunned).  Because of it’s unusual strength, much lees adhesive is needed compared to traditional construction adhesives.  Place cartridge in caulking gun and puncture seal inside spout with nail.  Apply by forcing adhesive onto surfaces.  When working on ruff surfaces, use enough adhesive to fill gaps.  PL® Marble and Granite will bridge up to 3/8”.  Use mechanical fasteners to hold the surfaces in place until the adhesive fully cures.  Drying time may very, depending on the humidity and porosity of the materials bonded together.  PL® Marble and Granite reactive nature allows the formulation of high strength in less then 24 hours.  Material may be repositioned up to 20 minutes without losing adhesive strength.
