How to Maintain Your Composite Decking in Singapore?

Composite decking is a popular choice among homeowners in Singapore due to its durability, low maintenance requirements, and aesthetic appeal. However, like any outdoor surface, composite decking requires regular cleaning and maintenance to keep it looking its best. In this article, we will discuss the essential steps to maintain your composite decking in Singapore, from regular cleaning to preventing fading and even scratch repair. By following these guidelines, you can ensure the longevity and beauty of your wood plastic composite decking for years to come.


Regular Cleaning

Similar to other types of balcony decking or outdoor decking material, composite decking requires regular cleaning to maintain its appearance and integrity. It helps to remove dirt, debris, and stains that can accumulate over time. To effectively clean your composite decking, you will need a few basic tools and cleaning agents.

Necessary Equipment


Before you begin the cleaning process, gather the following equipment:

  1. Soft bristle brush: A soft bristle brush is gentle enough not to damage the surface of your composite decking but strong enough to remove dirt and stains.
  2. Warm water: Warm water will help to loosen dirt and grime for easier removal.
  3. Mild dish soap (ammonia-free): A mild dish soap is an effective and safe cleaning agent for composite decking.
  4. Distilled white vinegar: Vinegar is a natural cleaning agent that can help to remove tough stains and kill bacteria.
  5. Bicarbonate of soda: Bicarbonate of soda, also known as baking soda, is a powerful cleaner and deodorizer.
  6. One teaspoon of lemon juice: Lemon juice can help to remove stubborn stains and add a fresh scent to your composite decking.

Preparing Your Deck

Before applying any composite decking cleaning and maintenance tips, ensure you’ve removed any furniture, plants, or other objects from your composite decking. This will make it easier to access all areas of the deck and prevent any damage to your belongings during the cleaning process. Additionally, ensure that the deck is dry before you begin cleaning to prevent any accidents.

Sweeping Your Deck

Begin by sweeping your WPC decking with a broom or a leaf blower to remove loose dirt, leaves, and other debris. Pay special attention to the spaces between the boards, as these areas can accumulate dirt and debris over time. By removing loose dirt and debris, you will make the cleaning process more effective and prevent scratches or damage to the surface of your composite decking.

Rinsing the Deck and Preparing a Soapy Water Solution

Next, thoroughly rinse your composite decking with water to remove any remaining loose dirt and debris. Use a garden hose or a pressure washer on a low setting to ensure an even and thorough rinse. Once the deck is rinsed, prepare a soapy water solution by mixing warm water and a few drops of mild dish soap in a bucket. This solution will be used to scrub and clean the surface of your composite decking.

Scrubbing and Removing Dirt and Debris


Dip the soft bristle brush into the soapy water solution and scrub the surface of your composite decking in a circular motion. Pay extra attention to areas with stains or stubborn dirt. For tougher stains, you can add a small amount of distilled white vinegar or bicarbonate of soda to the soapy water solution. These natural cleaning agents will help to break down the stains and make them easier to remove. Avoid the use of abrasive cleaning tools or harsh chemicals, as they have the potential to inflict damage on any of the different composite decking designs.

Thoroughly Rinsing Your Deck


After scrubbing, rinse your composite decking thoroughly with water to remove any soap residue. Again, use a garden hose or a pressure washer on a low setting for an even and thorough rinse. Make sure to rinse all areas of the deck, including the spaces between the boards. Soap residue left on the surface can attract dirt and make your composite decking appear dull or discolored.


Regular Inspection


In addition to regular cleaning, it is essential to inspect your composite decking regularly for any signs of composite decking damage or wear. Check for any loose boards, nails, or screws and tighten or replace them as needed. Inspect the surface for scratches, cracks, or fading, and address any issues promptly to prevent further damage. By catching and repairing any damages early on, you can prevent the need for decking repair or decking replacement.


Scratch Repair

If you notice any scratches on your composite decking, there are several methods you can use to repair them. For minor scratches, you can easily apply the same steps as DIY wood decking repair tips, such as using a heat gun or a hot iron to heat and expand the scratched area, causing it to blend in with the surrounding surface. For deeper scratches, you can use a composite decking repair kit that includes a filler and a color-matched epoxy. Follow the instructions provided with the repair kit carefully to ensure a seamless repair. 


Preventing Fading


One of the benefits of choosing composite decking is its ability to withstand sunlight. However, it can be susceptible to fading over time due to long exposure to sunlight and other environmental factors. To prevent fading and keep your composite decking looking vibrant, consider the following tips:

  1. Apply a UV-resistant sealer or stain: A UV-resistant sealer or decking varnishing can help to protect your composite decking from the damaging effects of sunlight and prevent fading.
  2. Place rugs or mats in high-traffic areas: Placing rugs or mats in high-traffic areas can help minimize wear and tear on your composite decking and prevent fading in those areas.
  3. Trim nearby trees and shrubs: Overhanging branches and foliage can cast shadows on your composite decking and promote uneven fading. Regularly trim nearby trees and shrubs to allow for sufficient sunlight exposure.
