|Make sure the column top is dry and free of dust or other debris. Take this opportunity to confirm that the column is square and level.
||Turn the Keystone KapStone upside down and apply the specially formulated Keystone KapSeal™ (or a comparable specialty formula of construction adhesive) to the square recessed area on the underside of the cap. Apply the adhesive in a 1/4 inch bead, making sure that the bead will make good contact with each unit in the top course of the column.
||Holding the Keystone KapStone upright, place the cap on the column. Twist the cap back and forth slightly to insure a good adhesive bond. Measure for square and center on the column. Check for visible adhesive. Follow the directions on the adhesive packaging for clean up and drying time.
