How to properly care for composite decking so that it lasts for years?

Cleaning dark WPC decking with a pressure washer

Composite decking is among the most durable outdoor flooring solutions, but it is not completely maintenance-free.

 If you care for it properly, it can serve you for many years and still look like new. Here are a few maintenance tips:

1. Regular cleaning

  • Routine cleaning: Sweep the decking once every few weeks or as needed to remove dust, leaves and dirt.
  • Deep cleaning: Wash it at least once a season with a mild cleaner and water. Use a soft brush or cloth to remove stains and grease.

2. Stain removal

  • If stains from food, oil or wine occur on your decking, clean them as soon as possible. The longer they remain on the surface, the harder they are to remove.
  • For tougher stains, you can use a mild WPC cleaner or soapy solution, which you can find in our range 

3. Avoid abrasive cleaners

  • Do not use wire brushes, harsh chemicals or a pressure washer with a narrow nozzle jet, as these could damage the surface. If you use a pressure washer, set it to low pressure and keep the nozzle at a distance of at least 30 cm from the surface.

4. Preventing damage

  • Protection from heavy objects: When moving furniture or a barbecue, take care not to scratch the surface. Use protective pads under furniture legs.
  • Preventing water pooling: Ensure proper gradient and water drainage so moisture does not accumulate on the decking, which could cause algae or mould.

5. Seasonal inspection

  • In spring and autumn, check the decking for visible signs of wear or minor damage. Minor scratches can be lightly sanded or treated with special WPC repair kits.

6. Maintaining colour

  • WPC decking is UV-resistant, but it may fade slightly over time. This is a natural colour stabilisation process. To preserve colour intensity, you can use special WPC care products.

7. Winter protection

  • It is not necessary to cover the decking, but clear snow regularly with a soft shovel to avoid an accumulation of ice or snow, which could become slippery.

With these simple steps, your composite decking will retain its beauty and functionality for years to come. 😊
