I hope that in designing the QE they put more thought into the flight deck than we did with the America class ships. The F 35B and Osprey V-22 engines run very hot (unlike the cool Pegasus in the Harrier) and are damaging the deck surface. A little like some of the early jets and downward exhaust (also running on Petrol). Right now the number of flight ops are reduced but the USN says that the newer ships will be fine. I'm not sure but I think the Soviet Kirovs had a tile surface for the Forger VTOL and did not have the damage we are seeing here.
Good luck to you all.

That's why the RN/RAF have the ski-ramp for take-off, and are training for using the SRVL (Shipborne Rolling Vertical Landing) method rather than the vertical landing method used in the Harrier days.
