Wood Impregnations and Treatments: Protect and Preserve Timber
Wood impregnations and treatments are used across a variety of settings to maintain the appearance and structural integrity of timber. Common applications include garden furniture, outdoor decking, fence panels, structural beams, and interior woodwork. In heritage projects, treatments help restore and protect historical timber features, or our range of wood finishes.
The primary benefits of using wood treatments include enhanced resistance to moisture, fungal decay and insect damage. Anti-fungal products help maintain hygiene in damp environments. Water-repellent treatments reduce the risk of swelling and warping, particularly in outdoor applications.
