Instructions for Installing Permat:

1. Ensure substrate is clean, dry, flat, and load-bearing.
2. Apply a slightly liquid thinset mortar mix to the substrate.
3. Lay Blanke Permat panels, overlapping the mesh overhang to cover seams.
4. Offset subsequent rows by a minimum of 3" to avoid seam alignment.
5. Press panels into the thinset with a trowel or vinyl roller.
6. Fill voids with thinset using the flat side of the trowel.
7. Set tiles using an appropriate notch trowel and follow movement joint requirements per industry standards.
