Licensed Biocides - Decking/Timber

For decking and timber, our licensed biocides provide robust protection against algae, lichen, and other organic growth, ensuring a clean, well-maintained surface. However, when applying biocide to painted or oiled decking, we recommend rinsing the biocide off after one hour. Since biocides cannot penetrate painted or oiled finishes, leaving them on the surface poses a risk by remaining active.

In colder conditions, BioClear 50 Pro is recommended for timber care due to its solvent component, which enhances performance in low temperatures, making it suitable for year-round maintenance. To ensure a safe and compliant application, carefully follow product guidelines, use appropriate PPE, and manage runoff to prevent contamination of surrounding areas. With PureSeal’s licensed biocides, professionals can achieve thorough, safe results on decking and timber surfaces while addressing specific requirements for coated finishes.
