Concrete surface coatings, either organic or inorganic, have long been used for the protection of reinforced concrete. The aim of the present work was to compare, in the presence of chloride ions, the performance of an acrylic emulsion and an inorganic coating, when the latter is or is not combined with an inorganic corrosion inhibitor. The behaviour of the inorganic coating was examined, as its use is increasing due to environmental reasons and it can be applied on concrete surfaces for the rehabilitation of old structures. Strain gauge (SG) technique, half‐cell potential measurements, mass loss and carbonation depth measurements, as well as chloride diffusion rate, revealed that the acrylic emulsion provides better protection for reinforcing steel in concrete than the inorganic coating. However, the combination of the inorganic coating with the corrosion inhibitor provides a higher level of protection against steel bar corrosion.
