INSTALLATION STEPS 1. Prepare and check the concrete slab : A. The slab must respect a flatness of +- ¼'' over the entire surface. B. The slab must exceed the size of the walk-in by 6'' on the perimeter. C. The compressive strength of the concrete shall be of 28 MPA. 2.
3. Sealing ceiling panels seams : A. Completely remove the protective film on all ceiling panels. B. Over a clean and dry surface, apply aerosol primer at every panel seam (approx. 9’’ wide) taking care of protecting the surrounding exposed metal.
