The sudden and unforeseen 2021 collapse of the 12-story beachfront condominium in the Miami suburb of Surfside, Florida, United States is a wakeup call for building safety particularly to those older buildings facing the same seaside environment. In this paper, the authors provide test data and proven evidences in related fields for a surface, field applicable PVDF coating solution that arguably can arrest and stop further concrete degradation and rebar corrosion of reinforced concrete structures and buildings. A field applicable (by brushing, roller coating, or spraying) patent-pending PVDF coating when applied on the outside of the reinforced concrete structure, can provide protection for preventing concrete from carbonation and other chemical reactions and protect the steel rebar from corrosion. For a thickness of 30 µm 100% PVDF coating, established various scientific data and experiments reported here can provide more than 100 times that of the epoxy coated rebar in terms of corrosion protection by blocking off moisture and corrosive gases from penetrating through the thin field applicable PVDF concrete coating. In the experiments of exposing reinforced concrete subjected to saline water exposure, the rebars encased in concrete coated with the field applicable PVDF coating in comparison to those without PVDF coating showed the additive characteristics of concrete and that of the PVDF coating along with the synergistic aspect of PVDF coating on top of concrete also protected the concrete from the chemical reactions with the corrosive water laden with dissolved salt ions.
