How to Prevent Scratches on Composite Decking Boards? A Guide for Terrace Users

Composite decking boards are one of the most popular solutions for terraces – and for good reason. They are durable, weather-resistant, require no oiling or painting, and look modern and elegant. Although they are a high-strength product, this does not mean they are completely scratch-proof. In this article, we will explain how to effectively protect your composite decking from mechanical damage so you can enjoy its excellent appearance for many years.

Do composite decking boards scratch?

Yes – although more resistant than wood, composite decking boards can still get scratched. The most common causes are:

• moving outdoor furniture,

• sand and gravel brought in on shoe soles,

• plant pots, grills, toys, children’s bikes,

• careless cleaning work (e.g., sweeping with a hard-bristle brush).

1. Keep it clean – this is the key

The grooved surface of the boards is practical and functional – perfect for everyday use and providing better slip resistance. It is an excellent choice for those who want to combine a modern look with easy terrace maintenance. Boards with a woodgrain finish impress with their natural character and elegant design. However, scratches are slightly more visible on these than on grooved boards. This is why regular cleaning and avoiding sand accumulation – which can wear the surface – is especially important.

Regardless of the board type, regular care is the simplest way to keep them fresh and well-maintained.

Care tips:

• Sweep your terrace regularly, especially during summer and after rain, when dirt settles between grooves.

• Use a soft brush – hard tools can deepen micro-scratches.

• Wash the boards with water and a mild cleaning agent, avoiding harsh chemicals and products intended for natural wood.

2. Don’t slide – lift

Sliding furniture, plant pots, grills, or other heavy items across the terrace is one of the most common causes of scratches. Even small movements of a chair or table – especially in high-traffic areas such as dining zones, lounge areas, or entrances – can damage the surface of the boards. What’s more, any deeper scratch can start to collect dust and dirt over time, which not only worsens the appearance but also makes cleaning and maintenance more difficult.

The best practice is to lift furniture instead of sliding it – even if it’s lightweight.
It is also worth using rubber or felt pads under furniture legs – especially for pieces that are frequently used and moved.
Heavy plant pots, storage boxes, or grills are best placed on protective mats or special pads that absorb pressure and prevent direct contact with the decking boards.

3. Ensure proper protection during winter

Although composite decking boards are resistant to changing weather conditions, winter can be especially challenging. Snow, frost, and low temperatures can increase the risk of micro-scratches, particularly if snow is removed using tools that are too hard.

• Use snow shovels with a rubber edge to avoid damaging the surface.
• Do not use salt or harsh chemical agents – they may react with the composite material and cause discoloration or micro-damage.

4. Prevention saves money in the long run

Remember – proper maintenance and preventing damage is not only a way to keep your terrace looking beautiful, but also a real cost saver. Repairing deeper scratches or replacing damaged boards can be both expensive and time-consuming.

• Regular care of the terrace surface extends its lifespan.

• You avoid costs related to renovation or replacement.

• You enjoy an aesthetic, comfortable outdoor space for many years.

5. Can composite decking boards be additionally protected?

Composite decking boards are designed for maximum durability – they do not require oiling, varnishing, or impregnation like traditional wood. This is a huge time and cost saving in maintenance. But if you want even greater resistance to daily wear, it’s worth making the right choice already at the purchasing stage.

6. How to remove minor scratches and stains?

Even with careful use, small scratches or stains can occur – especially in high-traffic areas. Fortunately, the right approach can quickly restore your terrace’s great look without the need for professional intervention.

Food, grease, or drink stains? Act quickly. Fresh stains are best removed immediately – with warm water, a mild detergent, and a soft brush. For oil-based stains, a mixture of water and dishwashing liquid can help – the sooner you react, the lower the risk of discoloration.

Minor scratches? If you notice slight abrasions on grooved boards, you can gently smooth them with sandpaper of 60–100 grit – always following the direction of the grooves. This type of finish masks micro-damage well, so small touch-ups will not be visible. For boards with a woodgrain finish – brushed or imitating natural wood texture – sandpaper is not recommended, as it may damage the aesthetic effect of the surface. In such cases, it’s better to stick to cleaning and maintenance without mechanical interference.
