Lignum Wood Preserver is a professional-grade, ready-to-use timber treatment formulated to protect interior and exterior wood from rot, decay, and wood-boring insects such as woodworm. Combining a powerful blend of fungicides and insecticides, this microemulsion water-based formulation penetrates deep into timber, ensuring long-lasting protection and preventative action.

Unlike traditional timber treatments, Lignum uses nanometre-sized particles to reach deep into porous wood, delivering active ingredients directly where needed. Its low-odour, non-flammable, and quick-drying formulation allows for safe, convenient application with minimal preparation, either by brush or low-pressure spray.

Lignum Wood Preserver is certified to European and industry standards (BS EN 46 for house longhorn beetle, BS EN 113 for wood-destroying fungi) and is authorised under the European Biocidal Products Regulation (528/2012), guaranteeing adequate protection against a wide range of wood-damaging organisms.
