Composite decking is loved for its low maintenance and long-lasting durability, but what if you want to change its color? Can you paint or stain composite decking like you would with wood?
The short answer: It depends on the type of composite decking you have. In this guide, we’ll break down whether painting or staining is possible, the best methods, and expert tips to keep your deck looking great.
Can You Paint or Stain Composite Decking?
Yes, you can paint or stain older, uncapped composite decking.
No, painting or staining is not recommended for newer, capped composite decking.
Uncapped composite decking, found in early-generation products, is more porous and can absorb paint or stain. Capped composite decking, which has a protective outer shell, is designed to resist moisture, stains, and fading—making paint or stain unlikely to adhere properly.
Before starting, check with your decking manufacturer, as painting or staining could void your warranty. Don’t forget to check out decking add-ons.
When Should You Consider Painting or Staining Composite Decking?
There are a few reasons why you might want to paint or stain your composite deck:
Fading Over Time – Older, uncapped composite decking can fade after years of UV exposure, leading homeowners to consider painting or staining for a refreshed look.
Scratches and Stains – If your deck has deep scratches, stains, or wear that cleaning won’t fix, a fresh coat of paint or stain might help.
Aesthetic Change – If you want to update your outdoor space with a new colour, painting or staining may be an option (but only if your deck allows it).
How to Paint or Stain Composite Decking
If you have an older uncapped composite deck and decide to paint or stain, follow these steps for the best results:
Step 1: Clean the Deck Thoroughly
Use a composite deck cleaner or mild soap and water to remove dirt, mildew, and debris. Let it dry completely before painting or staining.
Step 2: Sand the Surface (If Needed)
Lightly sanding with 220-grit sandpaper helps roughen the surface, allowing better adhesion for the paint or stain.
Step 3: Choose the Right Paint or Stain
Opt for:
✔ Acrylic latex exterior paint (for painting)
✔ Solid or semi-transparent stain designed for composite decking (for staining)
Avoid oil-based paints, as they don’t adhere well to composite materials.
Step 4: Apply a Primer (If Painting)
A high-quality exterior bonding primer ensures better adhesion before applying paint.
Step 5: Apply the Paint or Stain
Use a high-quality paintbrush, roller, or sprayer for an even coat. Apply thin layers, letting each dry before adding another.
Step 6: Let It Cure
Allow at least 24-48 hours before walking on the deck to ensure proper drying.
4. What Are the Downsides of Painting or Staining Composite Decking?
Before you grab a paintbrush, here are a few things to consider:
Ongoing Maintenance – Unlike the low-maintenance nature of composite decking, painted or stained surfaces will need touch-ups over time.
Peeling & Chipping – Paint can peel or chip, especially on capped composite decking, leading to a patchy look over time.
Warranty Issues – Some manufacturers void warranties if paint or stain is applied, so check before proceeding.
When Should You Start Upgrading Your Outdoor Space?
Do you have big plans for your garden this year? Homeowners are not more daring and taking on DIY to upgrade their outdoor space. This can be for a variety of reasons, including spending more time at home, wanting to save money and looking for a project to keep them busy. No matter what the reason is, transforming your garden has the ability to improve your property in terms of price and aesthetics.
So, when is the ideal time to start upgrading your garden? We all know that British weather can dictate when you start an outdoor project. Generally, most people agree that spring is the best time to work in the garden. Of course, this is due to the weather improving after the winter. The sun starts to shine, and the nights start to get longer. But, it can also be due to motivation and feeling like you’re getting over the winter gloom. Indeed, you have a renewed sense of energy and feel excited to start working on a project. Starting now means that you can have everything done by summer.
Let’s not forget that if you’re trying to introduce green into your garden, spring is the time when things start to grow again. The trees and plants come out of dormancy and are going to sprout new leaves and flowers. So, you can make sure that you add colour to your garden, and they can thrive during the summer. When it comes to the ground, it’s going to be a lot more stable in the better weather. The soil can dry up, which means that it’s easier to work on projects like decking and paving.
Final Thoughts: Should You Paint or Stain Composite Decking?
If you have an older, uncapped composite deck, staining or painting might be a good option to refresh its look.
If you have a newer, capped composite deck, painting or staining is not recommended and may void your warranty.
For a low-maintenance, long-lasting deck, consider cleaning, adding shade, or using decorative elements instead of painting.
