probably the only thing that will hold up to that type of traffic LONG TERM is to coat with EUCLID CHEMICAL SUPER DIAMOND CLEAR (part of the DIAMOND HARD product family (youare familiar with it, LOWES, WALMART & HOME DEPOT all use it for floors that need to hold up to that sort of traffic.)
EUCLID was a client, & we have had them quote on another client's floor. IT AIN'T CHEAP!
an 80,000 sq. ft. section of warehouse floor was over $500,000 12 years ago. it can only be installed by certified installers (they will NOT sell for self install)
i have lost contact (all our local people aged out & retired) with euclid, (the own rustoleum and a bunch of other major, recognizable brands)
IF I REMEMBER NOTAREALSIGNGUY had some experience with this type of product as well.
there may be other products made for this type of traffic but, as far as i know, diamond hard is the gold standard.
i was never affiliated with euclid in that capacity, but was a NJ IT tech support vendor & got very friendly with their local product support staff, ever since the 1990's
