Abstract: Limestone is commonly used as a cladding material in construction.
It is generally believed that limiting the absorption of the stone will eliminate durability problems, and this is reflected in the standards.
Consistent with that approach is the practice of applying surface treatments to seal the stone, with the object of improving durability.
Site observations indicated that such treatments are not always effective in enhancing durability, and therefore the current study was undertaken to assess the performance of sealing treatments by accelerated laboratory tests.
It was shown that different types of treatments which resulted in marked reduction of absorption, which was maintained after aging, were systematically associated with improved durability performance only in the case of accelerated salt exposure.
In a combined UV and wetting/drying exposure there was no consistent trend of improved durability with reduced absorption.
The polished surface of the stone yielded better durability performance than the unpolished one.
