Product description:

Nourish & Protect

Specifically formulated for use on pressure treated and preservative impregnated timber offering superb protection to deck boards, deck tiles and balustrades. 

Also achieves a superior finish to summerhouses, sheds and fences. Non-flaking and its water repellency help prevent timber from splitting and cracking.

  • UV fade resistant pigments.
  • Contains a surface biocide preserver to protect against mould. 


The colour swatches are an indication only and representative of the product applied to clean new/pale timber. The final colour finish can vary considerably due to the age, type & condition of the timber being treated and will darken with multiple coats. Viewing colours on multiple digital screens can vary considerably and may not be totally accurate. We always recommend carrying out a small inconspicuous test area first. It is the Customer/end users responsibility to satisfy themselves that the colour finish is correct before full application.
