To assess the effectiveness of different nanomaterials for fresco consolidation in hypogeal environments.
Laboratory tests comparing nanolime, nanosilica, and nano Ba(OH)2
In situ tests on frescoes from Santa Maria della Grotta and Crispia Salvia.
Evaluation focused on breathability, color change, and stability.
Ba(OH)2 demonstrated strong consolidation with high breathability and minimal color change.
Nanosilica was effective but reduced vapor flow, impacting fresco condition.
Nanolime caused whitening and less stability compared to Ba(OH)2.

Implication

Randomized trial evaluates fresco consolidation effectiveness in hypogeal environments, suggesting barium hydroxide as the best option.

Abstract

• Compared nanolime, nanosilica, and nano Ba(OH) 2 for fresco consolidation. • Tests on frescoes from Santa Maria della Grotta and Crispia Salvia. • Ba(OH) 2 gave strong consolidation, high breathability, low color change. • Nanosilica reduced vapor flow; nanolime caused whitening, less stability. • Ba(OH) 2 proved most effective for humid, sulphated hypogeal frescoes.
