Applying Mortar Base Coats (Scratch and Score)

What happens here
Mix S-type mortar (a high-strength blend suitable for veneer) with water in a bucket using a paddle mixer until it achieves a peanut butter-like consistency. Apply a 'scratch coat' of this mortar to the metal lath, ensuring all honeycomb openings are completely filled and the metal mesh is no longer visible. Allow this layer to firm up for approximately one hour. Then, apply a 'score coat' using a 1/2-inch (1.27 cm) notched trowel to create horizontal grooves in the mortar. These grooves provide additional grip for the stone veneer, preventing it from sliding down. If the mesh moves during application, re-secure it with a nail or screw and continue.
Goal: Create a strong and textured mortar base for stone veneer.
