Can You Paint Composite Decking?
Yes, you can paint composite decking, but it depends on the type of decking and your long-term goals.
When It’s OK to Paint Composite Decking:
Older composite decks (first-generation, uncapped): These often fade over time and can be refreshed with paint.
If you’re committed to maintenance: Painted surfaces require regular upkeep, unlike bare composite.
When you're looking for a color change: Painting allows you to customize the appearance to match a new design or landscape.
When You Shouldn’t Paint Composite Decking:
Newer capped composites: Modern boards have a plastic shell that resists paint. Manufacturers often advise against painting and may void the warranty.
If you want low maintenance: Painting defeats the purpose of investing in composite over traditional wood.
