  • Best for: Decking, fences, sheds and outdoor furniture needing durable protection
  • Not ideal for: Projects requiring biocidal treatment or coloured stains and finishes

Waterproofs wood while reducing mould and algae and improving dimensional stability. Non-biocidal, ready-to-use formulation with a long lifetime and straightforward application.


Long-lasting water protection, thanks to deep-penetrating waterproofing

Deep-penetrating formulation moves into timber fibres to create water and UV repellency rather than sitting only on the surface. Reviews highlight strong penetration and sustained repellency over time.

Surfaces shed water more effectively and stay drier between maintenance cycles, reducing the risk of rot and extending usable life.

Reduced organic growth, with a non-biocidal formulation

Active ingredients are formulated to discourage mould and algae growth while remaining non-biocidal and ready to use. Product descriptions and reviews note lower visible mould and algae after treatment.

Less frequent cleaning and scrubbing of decking and fences, making upkeep quicker and less physically demanding.

Improved dimensional stability, thanks to moisture control

Treatment protects timber from warping by limiting moisture uptake and movement within the wood structure, a feature called improved dimensional stability in product literature.

Joints, boards and panels stay truer to size through seasonal changes, reducing the need for repairs or replacement.
