Interior and Exterior Wood Preserver

Lignum Clear Wood Preserver provides lasting protection against a wide range of wood rotting fungi including wet and dry rot as well as woodboring insects like woodworm. It can be used to preserve furniture, flooring, structural and other timbers.

The powerful fungicide tackles the rot whilst the insecticide is highly effective against all life stages of woodworm, protecting your wood from damage. It can be used on both old and new timbers.

The Lignum wood preserver comes ready to use, has virtually no odour and can be used on interior and exterior wood. It is easy to apply with either a brush or low pressure spray, delivering the convenience and flexibility required by both the DIY and professional user.

How Clear Wood Preserver Works

Lignum Wood Preserver combines an insecticide and a fungicide to prevent or eradicate woodboring insect attacks and prevent wood rot. The active ingredients include a commonly used insecticide that is highly effective against a wide range of woodboring insects and a fungicide that is effective against wood destroying fungi. 

This timber treatment uses microemulsion technology, a special formulation allowing for tiny particle size. This ensures that these active ingredients penetrate deep into the wood, giving you long-lasting protection.

How to Apply Wood Preserver

Preparation: Make sure the wood is clean and free from wood dust and other contaminants. You should then test the product on an inconspicuous area to make sure there is no effect on colour or finish.

Application: You can apply the wood preserver with a low pressure spray or brush. It is touch dry in one hour depending on the type of wood and the ambient conditions. You can add a second coat 24 hours after the first application – again this depends on the wood and conditions.

Coverage: 200ml per m2 (1 Litre per 5 m²)
