Roxil 100 Mould, Algae & Lichen Killer 5L - Wood & Patio Cleaner

Roxil 100 Wood & Patio Cleaner is a powerful biocidal treatment for external surfaces including timber, paving, fencing & decking. It targets and kills algae, mould and surface biofilm, helping to restore appearance and reduce the need for harsh cleaning methods. The formula is biodegradable, water-based and long-lasting. This cleaner is ideal as a preparatory step before applying treatments such as Roxil Wood Protection Cream or Roxil Patio Cream. It can be used on both horizontal and vertical substrates and is suitable for wood, concrete, stone and masonry. Apply in dry weather using a brush, roller or sprayer. Each litre treats up to 5 m2 depending on surface porosity. Allow the product to sit for at least 1 hour, or ideally 24 hours, before rinsing. As the active ingredients take effect, algae will darken in colour before loosening. Use a stiff brush and garden hose for best results. A pressure washer may be used with care, though repeated use may erode patio joints or affect timber finish. Avoid contact with plants and non-target surfaces. Store above 5 degrees C and keep out of reach of children or animals until dry. Not suitable for use on surfaces affected by heavy lichen without abrasion.
