Insecticide & Wood Preserver

This Universal Wood Preserver protects timber from wet and dry rot, general wood rot, blue stain as well as wood-boring insects. Combining two fungicides and an insecticide, it is a highly effective easy to use product that delivers long lasting protection to new and old timber including furniture.

This wood preservative can be used during the drying out period after the elimination of the source of damp. As a universal preservative it is highly effective, offering protection against a range of wood rotting fungi and various staining fungi.

The powerful insecticide ensures that it will prevent as well as eradicate any wood boring insects including woodworm. The product is suitable for interior use on furniture, flooring, structural and other timbers.

With virtually no odour, this wood preserver can be applied either by brush or low pressure spray to provide lasting protection. As a water-based product, it is free from solvents and is non-flammable.

How Universal Wood Preserver works

Lignum Universal Wood Preserver is based on microemulsion technology which produces a formulation with tiny particles. The size of the particles means that the active ingredients - a powerful insecticide and two fungicides - can penetrate deep into the wood.

All active ingredients have a proven efficacy against a range of wood staining fungi, wood rot and wood boring insects.
