Lignum Pro D156 Timber Treatment

Lignum Pro D156 is a dual purpose (Fungicide / Insecticide) treatment based on microemulsion technology which produces a formulation with a particle size in the nanometre range. This tiny particle size allows the formulation to penetrate deep into the timber in order to deliver the active ingredient (a combination of fungicide and insecticide) to prevent or eradicate insect attack and to prevent fungal decay and staining.

Lignum Pro D156 is effective against a wide range of wood rotting fungi (both Wet Rot & Dry Rot) whilst the pyrethroid insecticide is effective against all life stages of wood boring insects. It has virtually no odour and can be applied either by brush or low pressure spray to provide long lasting protection.

The formulation is water-based producing a non-flammable, quick drying product containing no volatile organic compounds (VOCs). The concentrated product is diluted with water.
