How to maintain composite decking in the UK climate
If your wondering how to maintain composite decking in the UK climate, here's a complete guide to keeping your outdoor space looking stunning all year round
Regular cleaning is essential
Unlike traditional wood, composite decking won’t rot, splinter, or need annual staining, but it still benefits from routine cleaning.
- Sweep weekly to remove leaves, mud and dirt that traps moisture
- Wash with warm soapy water and a soft brush every couple of months
- For stubborn marks, use a specialist composite decking cleaner
Stop algae, moss and mould growth
The UK’s damp climate encourages moss, mould and algae especially in shaded gardens. Not only can this make decking look tired, it can also become slippery.
- Apply a moss and algae treatment in spring and autumn
- Rinse thoroughly with a garden hose after applications
- Keep the decking free of standing water by ensuring drainage gaps aren’t blocked
Protect Against Everyday Stains
From summer BBQ’s to flowerpots, there are plenty of ways decking can get stained. Composite boards are more resistant than timber, but prevention is still best.
- Clean food and drink spills quickly to avoid marks
- Use plant pot risers to prevent water rings
- Place mats or trays under barbecues and outdoor heaters
Winter Decking Care: Frost and Ice
Composite decking is stronger in cold weather than timber, but the surface can still become slippery in the frost and snow
- Remove snow with a plastic shovel or soft brush – Never use metal
- If de-icing, use calcium chloride or rock salt sparingly
- Rinse off any residue once conditions improve
