Overview of the Challenges and Current Solutions in Coatings for Historical Monuments and Architecture

Abstract

Mankind has erected monoliths and stone structures for millennia to ensure stories and culture are passed on to future generations. In the modern era, monuments and architecture are designed with the intention of lasting several decades to hundreds of years and may utilize an arrangement of natural and synthetic materials. Choice of substrate helps ensure the longevity of these structures, but coatings are utilized to provide additional characteristics and subsequent protection to the finished product. Protective coatings come in a variety of base materials and are utilized to address specific degradation concerns of the project managers. Advances in this field focus on protection of the surface while preventing any unintended damage to the substrate. This mini‐review summarizes the advances in protective coatings useful for historical monuments and architecture up to January 2024.
