Although unnecessary and not usually recommended, yes, you can paint composite decking. As composite is manufactured with synthetic plastic fibres in its production, it is not required to paint or seal your composite decking in order to retain its appearance or longevity.

Composite decking comes in various colours and textures; thus, you can choose the colour best suited to your outdoor space without the time-consuming chore of painting your decking. Unlike timber material which requires painting and sealing to ensure it will achieve its service life and resist moisture.

Composite decking naturally has resistant qualities due to its synthetic composition; therefore, it does not require painting. A huge benefit for busy homeowners who do not want to spend extensive time and money on maintenance.

Despite this, some customers still choose to paint their composite decking for various reasons; you may wonder when you might need to paint your composite decking.

Why Do Customers Choose to Paint Their Composite Decking?

  • Fading- You may choose to paint your composite decking if it has experienced fading from UV rays. As composite decking, especially first-generation decking, is susceptible to fading up to 30% in the first six months, you may wish to paint your decking boards to return them to their original colour. First-generation decking will experience more fading than second-generation boards, as they are less protected and don’t have a co-extrusion layer. Therefore, it is recommended to invest in second-generation composite decking rather than painting over first-generation composite decking as this will last much longer and experience significantly less fading in comparison.
  • Scratches- Some consumers choose to paint their decking if they have any scratches on their deck surface to try and hide the mark. We recommend removing any scratches in alternate ways, such as heat guns on wood grain boards or a steel scourer on smooth finish boards. To learn how to maintain your composite decking properly and deal with scratches or marks, check out our article on maintenance. 
  • Aesthetic- Homeowners may opt to change the exterior of their property and have a change of style which they decide doesn’t match their current composite decking. This can be an issue due to the extensive lifespan of composite decking, created to last for decades.

Types of Paint You Can Use for Composite Decking

The type of paint you use on your composite decking should be high quality and specifically designed for composite decking. You can utilise deck pigment to ensure the colour you desire; we recommend using a good latex deck pigment with a gloss finish.

Paint with a high solid content will last a long time on your decking; latex acrylic paint will ensure your deck retains the paint throughout its lifespan better than lower quality paints. Latex paints are best for increased durability and reduced fading. In most cases, the more expensive the decking paint, the more acrylic the paint will contain.

How to Paint Your Composite Decking

Before painting your composite decking, you must first thoroughly clean the decking and leave it to dry. Once again, refer to our ultimate maintenance guide to learn how to properly clean your deck surface without damaging the boards. 

If there are any repairs needed on the decking boards, this must be completed before the pigment is applied. The paint can be mixed in a bucket and applied with a brush or a roller evenly across the deck surface.

Ensure you remove anything that is close to the decking surface that could accidentally get paint on it, or be sure to cover any surrounding furniture to avoid this issue.


Although it is not necessary to paint your composite decking, due to its many beneficial attributes making it resilient to moisture, you can paint your decking if you wish as long as you use the correct paint or pigment suited to your composite deck and follow the steps in the above article. Alternatively, if you have experienced fading on your decking and are looking to restore its colour, you can utilise products such as OWATROL wood reviver to return the decking to its original colour.
