Composite decking (also known as wood plastic composite, or WPC) is an alternative form of decking built out of composite materials – wood fibres, plastics, and inorganic filler materials. Composite decking can be manufactured to very convincingly imitate the smell, feel and look of wood, but the care, maintenance and cleaning it requires is very different. In most cases, composite decks require a lot less effort to maintain than pure timber decks, and for many people not having to oil and stain the deck is one of the main selling points.

Composite decking is usually composed of fine wood particles (sawdust) and 50% or more recycled plastics. The plastic is either a Polyprepylene (hard plastic) or Polyethylene (softer plastics) and fine wood particles (wood flower). It is manufactured under heat and pressure to encapsulate the wood in the plastic and a UV inhibitor prevents any lightening in colour. Due to their amazing weather and UV resistant properties, they are far more durable than normal wood. They have the look and feel of real wood, but with lesser maintenance efforts.

We say lesser maintenance efforts so you will still have to clean it time to time. Here’s how you do it.

Regardless of the choice of decking you choose to install, the common surface dirt is a norm. We will advise you to occasionally clean it with soap and brush, preferably one with soft bristles to ensure that the surface dirt are properly clean off. If you leave the dirt to build up for too long on your deck, it might encourage growth of mould and bacteria – which makes it harder to clean and is bad for the environment. If you are unsure on which cleansing solution to use, it is best to seek the advice of your manufacturer.

Unlike PVC decking, wood composite decking is permeable and staining can become quite an issue on hand. The severity of the staining depends on the factor that causes it and also the treatment that it had gone thru. If you happen to spill wine or drop food substance on your decking, please clean it up immediately with soapy water and brush. Don’t leave it there to sit, because the longer it sits on your deck, the harder it is to remove.

For tough stains that have been sitting on the deck, try to remove it with soap water and brush first. If it doesn’t go off, get advice from your manufacturers before you apply any cleaning agent as it may result in damage if a wrong cleansing agent is used.

Mould and mildew are probably the most frequent issue people experience with WPC decking. Over the years mould has been a persistent issue despite the improvement in the technology applied to the decking.

For this, we will recommend regular cleaning and reducing exposure to constant damp conditions for your decking. If you do get mould, it is better to check with you manufacturer on the elimination solutions. Do not just apply any treatments you search on google.

Mould is perhaps the biggest problem people tend to experience with composite decking – and in the past, there have even been class action suits filed against decking manufacturers by customers who are unhappy with how readily mould has grown on their decking. Technologies do improve though, and there are ways to clean mould from decking as and when it appears.
