A variety of coating materials are available as finishing materials that suppress carbonation, which is the main cause of degradation of reinforced concrete buildings in general. Therefore, accelerated carbonation tests, outdoor exposure tests, and carbon dioxide gas transmission rate tests were carried out in various water-based finishing materials, and the carbonation suppression effect was confirmed for the purpose of improving the durability of reinforced concrete buildings. The possibility of predicting the suppression effect of the coatings through a mathematical formula was also examined.
