Can it be painted

For Tec7 WP7-301 Roof Waterproof Repair Paste, the manufacturer info we have does not explicitly say that it is over‑paintable, and it also notes that the product “always remains a bit tacky” and is intended to be finished with chippings for extra protection and walkability rather than a paint layer. That usually means it is not designed to be painted like a rigid, dry roof coating.
