Exterior ply is such because it meets a certain test criteria, the CE2+ test. It does not imply any grade of the facing ply. To get a grade of the facing ply, you would buy ply with a specified grade.
It might seem harsh, but if you do not understand the specification / grading of something it’s not the sellers fault it’s the buyers.
The Wicks advert does not state anywhere that I can see the grade of the facing ply. So, absolutely anything is acceptable as it would meet the CE2+ test criterion. The picture of the ply they use is fully compliant with the rest of the advert. It’s not misleading or inaccurate.
