⚠️ SAFETY NOTICE: Wear gloves, eye protection, and a dust mask when cutting or handling Vello Stone.

A. Cutting

• Use a circular saw or angle grinder with a masonry blade to shape tiles as needed

B. Adhesive or Mortar Application

Choose one of the following methods:

1. Silicone Adhesive Method:

• Use (high-performance, construction-grade silicone or hybrid adhesive – MS Polymer or Hybrid Polymer Adhesives)
• Apply adhesive in a continuous 1" perimeter bead on the back of each panel
• Add horizontal beads every 6" across the panel

2. Thin-set Mortar Method:

• Use (high-performance, large and heavy tile (LHT) mortars that meet the ANSI A118.15 standard)
• Skim coat the substrate with the flat side of the trowel
• Comb mortar in one direction with notched side held at 45° angle
• Ensure minimum 3/32" mortar thickness after pressing the panel
• Back-butter each panel for better adhesion, focusing on corners and edges

C. Installation

• Apply one panel at a time, pressing firmly into place
• Temporarily secure using pneumatic nails
• Check alignment with laser or spirit level

D. Finishing

• Clean surface with a dry cloth
• Fill joints with color-matching caulking
• Smooth and correct corners with scraper and sandpaper as needed

5. CORNERS - JOINTS

• For external corners, use miter cuts for a seamless finish
