Licensed Biocides - Block Paving

For block paving, our licensed biocides offer dependable protection against algae, lichen, and other organic growth, supporting a clean, well-maintained appearance. When applying biocide to sealed block paving, we advise rinsing off the biocide after one hour. This approach provides an initial biofilm kill but doesn’t deliver long-lasting protection, as biocides cannot penetrate sealed blocks and may remain active on the surface if not rinsed.

In colder temperatures, BioClear 50 Pro is recommended due to its solvent component, enhancing efficacy in low temperatures and making it ideal for year-round block paving maintenance. For a safe and compliant application, closely follow product instructions, use appropriate PPE, and control runoff to prevent contamination of surrounding areas. With PureSeal’s licensed biocides, professionals can achieve thorough and responsible results on block paving, with consideration for the specific needs of sealed surfaces.
