Licensed Biocides - Granite

For granite surfaces our range of licensed biocides provides effective protection against algae, lichen, and other organic growth, keeping granite clean and well-preserved. It’s important to note that on highly polished surfaces, residual protection may be limited, as the biocide cannot penetrate deeply. For rough or unpolished granite, biocides offer more enduring protection, as they can penetrate and provide ongoing resistance against organic buildup.

In colder conditions, we recommend BioClear 50 Pro, which includes a solvent component for enhanced performance in low temperatures, making it suitable for year-round granite maintenance. When applying these biocides, ensure they do not enter the water system. Carefully follow product instructions, use appropriate PPE, and control runoff for safe and compliant application. With PureSeal’s licensed biocides, professionals can achieve reliable results on granite surfaces, responsibly addressing organic buildup with attention to the stone’s finish.
