TanalithHigh Pressure Preservative Treatments

Next generation TANALITH wood preservative is designed for use in high pressure industrial treatments.

This renowned preservative gives a proven, outstanding performance, particularly for timbers intended for use in ground contact applications.

TANALITH wood preservative now incorporates patented BARamine technology. This provides an even more robust protection allowing greater penetration and  distribution of the wood preservative into the timber and provides a solution management system that ensures the preservative actives are balanced every time you treat timber.

TanatoneWe can offer a choice of TANALITH preservative which imparts an initial pale green colouration to the timber, or TANATONE brown colourant can be added to the TANALITH preservative to provide brown coloured treated timbers.

Shades logo

Tried and tested in American markets, Shades brings 2 contemporary colour options for TANALITH preservative treated cladding, fencing and landscaping timbers.

A choice of Slate Grey or Mahogany pigmented coating is first applied to cladding or garden timbers prior to the usual TANALITH high pressure treatment.

The resulting Shades treated timbers have all the protection properties of TANALITH treated timbers but with a superior colour performance that will last between 2-5 years.*

Timbers coated with different Shades colour product can all be treated within a single TANALITH treatment charge.


*Colour performance is a subjective matter and depends on individual circumstances. Like all colour systems the colour will lighten with age and exposure to the elements. However the effect will be gradual and consistent on similar exposed surfaces. Please note that south facing elevations may lighten quicker that north facing due to greater UV exposure.
