Professional dual treatment to protect against fungal decay and eradicate wood boring insects in timber.

Dual Treatment: Protect Against Woodworm & Fungi

This professional concentrated dual purpose product contains an insecticide and fungicide to protect and preserve timber. It is designed to eradicate and prevent attack by wood boring beetles and prevent wood destroying and discolouring fungi.

Lignum Pro D156 is effective against a wide range of wood rotting fungi including both wet rot and dry rot whilst the pyrethroid insecticide is effective against all life stages of wood boring insects. It is also effective against fungal staining.

The concentrated product is diluted with water and can be used during the drying out period after the elimination of the source of damp. It is virtually odourless and can be applied either by brush or low pressure spray to provide long lasting protection.

How does the Dual Treatment Work?

The dual purpose treatment uses microemulsion technology to ensure the active ingredients (a combination of insecticide & fungicide) can fully penetrate the timber. This product also contains IPBC (3-Iodo-2-Propynyl Butyl Carbamate) 31.25g/L: a carbamate fungicide that is added to provide excellent efficacy against a range of wood staining fungi.

How to Use Dual Treatment

Wood should be clean and free from wood dust and other contaminants.

Once diluted according to instructions, the woodworm and fungi treatment can be applied using a pressure spray or brush.

The dual treatment does not have a finish but it is always advisable to try on a small inconspicuous area before application to ensure product finish is as expected.

Wood treated with Lignum dual purpose treatment can be overpainted, varnished or stained once dry (usually an hour after application). It is suitable for over coating 24 hours after application.
