Roxil Wood Waterproofing Preserver & Sealer – 5L Clear

Roxil Wood Waterproofing Liquid is a clear, ready-to-use treatment designed to protect outdoor timber from the British weather without changing how it looks. It works by penetrating deep into the wood fibres, repelling moisture and helping to prevent the warping, swelling and cracking that comes with repeated wet and dry cycles through the seasons. Because it's completely clear, it lets the natural colour and grain of your timber show through, making it a great choice when you want protection without altering the appearance of your decking, fencing, shed or garden furniture.

One of its standout qualities is that it actively discourages the growth of mould, algae and other organic matter that tends to take hold on damp outdoor wood — particularly useful on shaded fences or decking that doesn't get much direct sun. It's non-biocidal, which means it achieves this through waterproofing rather than chemical treatments, making it a more environmentally considerate option for gardens where children, pets or wildlife are regular visitors.

The 5 litre size gives you plenty of liquid to cover a good stretch of fencing or a full deck, and because it's sold ready to use there's no mixing or diluting involved — just apply and let it do its job. It's well suited to anyone who prefers a low-maintenance approach, as the long-lasting formula means you won't need to reapply every season. A practical, fuss-free way to extend the life of your outdoor timber.
