Installation Guidance

To install natural slate coping stones, prepare a level surface on the wall and bed the copings onto mortar or an external adhesive. Maintain a consistent overhang on both sides to direct rainwater away from the wall face. For best results, keep joints uniform and compact. Slate copings can be cut on site with a diamond blade, and a breathable sealer may be applied for additional protection in exposed locations.
