How does granite’s mineral composition affect its resistance to pet waste chemicals?

Granite's resistance to pet waste chemicals is directly determined by its mineral composition. This natural stone is primarily composed of three minerals: quartz, feldspar, and mica. Quartz, being the hardest component (7 on Mohs scale), provides excellent resistance to both chemical attacks and physical abrasion from pet waste. Feldspar minerals, which constitute 40-60% of granite, are more vulnerable to chemical etching from acidic components in pet urine, potentially leading to surface dullness. Mica minerals, though present in smaller quantities, can create weak planes in the stone structure. The interlocking crystal structure of these minerals creates a dense surface, but the varying chemical stability of each mineral component results in different levels of porosity and reactivity. Higher quartz content generally correlates with better chemical resistance, while granite with higher feldspar content may show more susceptibility to etching and staining from repeated exposure to pet waste chemicals. Proper sealing can enhance the natural resistance provided by the mineral composition.
