Alternatives to Lime Plaster: Evaluation of Paints with Inorganic Pigments for the Conservation of Heritage Buildings in Peru

[EN] Lime plaster has historically been a key material in the preservation of architectural heritage in Peru; however, its availability has been restricted by state regulations that limit its production and commercialization. This study evaluates the performance of paints formulated with inorganic p...
