Abstract:
Protective coatings are often used to waterproof their substrate, to increase the durability of concrete, or simply to improve the aesthetics of a structure. However, there are side effects. For example, coatings that shed water would inhibit the curing effect that could be derived from subsequent wetting due to outdoor exposure. A protective coating could also increase the carbonation of its substrate since it provides a favourable dry environment for carbonation to proceed. This paper presents long-term results to illustrate these two ‘side effects’ on the use of protective coatings.
