Trex decking is typically made to last a lifetime, which means you will not have to paint it. You may come across some old composite decking that should be recovered due to an inadequate repair, but there are just a few issue spots.

Consequently, instead of wasting money, you may decide to save it. Notwithstanding producers’ claims that the colour of Trex decking is everlasting, it might fade over time.

Consequently, whether you need to completely change the colour of your Trex decking or give it a novel style, you may paint it. Put a layer of paint on it to make the Trex decking seem as good as possible. Let us take a deeper look at Trex Decking.

Is it possible to paint Trex or composite decking?

Trex composite decking is composed of polycarbonate and wood fibres. The artificial film used in hardwood decking might be made from polyethene terephthalate.

These polymers work well with wood fibres to create a robust, durable decking that is more robust than decking made entirely of silicone. Not all composite decking is the same.

Look at how composite decking is created because different materials have distinct cleansing and painting methods.

What are the many types of composite decking?

Composite decking is a broad phrase that encompasses a wide range of materials, including wood-plastic composite, topped composite, and polymer timber.

Wood-based decks are a low-maintenance, lengthy choice for individuals who do not need to spend lots of money on a deck.

Wood-plastic composites are manufactured from a combination of recycled plastic and wood fibres. Wood-plastic composite decking is sold by various companies, including Trex, Timbertech, and Pavilion.

Another element that adds to the appeal of wood-composite decking is its similarity to genuine wood.

This option gives homeowners the classic beauty of genuine wood while still delivering the benefits of composite material, like durability and dependability.

Topped composite decking: A topped composite is comparable to a wood-plastic composite, but it includes a rubber barrier that protects it from the elements even more than a standard wood-plastic composite.

This option is somewhat more expensive, but it will assist your deck in surviving longer.

Plastic-lumber decking: Unlike timber decking, plastic lumber decking comprises plastic. This product is environmentally friendly since it is typically made from recycled plastic.

Plastic timber may be made to seem like wood by imbuing it with wood grain, or it can be left flat.

Although plastic lumber is more costly than conventional hardwood and other fibreglass decking components, it is almost maintenance-free, highly weather-resistant, and robust.

Why would you need to colourize your composite deck?

Composite decking is one of the most popular choices because it is discoloured resistant and does not need painting. Contrary to common opinion, all types of decking, especially composites, fade with time.

It may not fade as fast as wood, but it may lose colour over time for various reasons. One of the most common reasons for fading is extended exposure to UV radiation and heat.

If your deck has discoloured due to age or extensive sunlight exposure, you should recolour it. One option is to use paint.

What are the coatings used on composite decking?

Although, before you make any changes to your deck, you can learn about the best type of paint to utilize. Not every colour is suitable for painting composite decking.

You will want to use the proper one for several reasons. The most significant disadvantage of choosing the wrong type of paint is that it might peel off rapidly, resulting in a financial loss.

High-quality latex paint is the simplest type of paint to apply on composite decking. Use semi-gloss or silk clinch paint to accomplish the glimmering and shimmer look.

However, it is good to check with the producer to see what colour options are available. They may provide a recommendation to you.

It is also worth mentioning that painting a deck may void the guarantee, based on the manufacturer.

What are the tools required to paint composite decking?

Though composite decks, such as Trex, are not constructed or required to be paintable such as their real wood counterparts, they do and will welcome paint if thoroughly sanitized, prepared, and primed.

Using a coating of paint or a deck stain on composite decking can assist in keeping the colour and charm of your deck while also extending its already lengthy lifespan.

The following is what you will need:

  • Soft-bristled surface cleaner brush
  • Cleaning supplies like vinegar and baking soda
  • Sandpaper
  • A scraper, paintbrush, cushion, or injector of paint
  • Appropriate Primer
  • Paint that you enjoy using


Outdated composite decking may be painted or dyed to look like a novel again. This will make your deck seem new again.

Keep in mind that the amount of effort you put into the job will influence whether you paint or stain. Because paint lasts longer, you cannot re-paint the deck once painted.

Whatever choice you select, remember to clean your deck. Eventually, the stain will not stick properly and will peel away. If this occurs, it appears that your endeavours have been in vain.

You can remedy spray paint errors by reading the relevant post. Thus, you can paint Trex decking.
