How Lignum Coloured Wood Preserver Works

Lignum Coloured Wood Preserver is based on microemulsion technology. This is all about creating a formulation with tiny particles that allows the active ingredients to penetrate deep into the wood. The size of the particles means that the two fungicides are highly effective and can provide long-lasting protection from wood staining fungi and wood rotting fungi.

How to apply coloured wood preservative


Make sure that your timber is clean and free from all contaminants including any previous coatings, dust and dirt.

TIP: We recommend testing the wood stain on a small inconspicuous patch and then allowing it to dry to ensure that it is compatible with the timber. Final colour shades are influenced by the dampness, density, and surface absorbency of the wood.


You can apply this coloured wood preservative direct from the container. Simply give the container a good shake with the lid on before using it. 

Lignum Colour & Preserve can be applied using a low pressure sprayer or brush. It is suitable for indoor and outdoor use.
