Can You Stain Composite Decking? Expert Guide for Washington Homes
If you’re a homeowner in Washington wondering, can you stain composite decking? The short answer is yes, but with important considerations. Composite decking was designed as a low-maintenance alternative to traditional wood, yet over time, many outdoor decks in Washington show fading, staining, or weathering because of constant rain, moss, and algae growth.
For residents in Tacoma, Gig Harbor, Bremerton, and the Kitsap Peninsula, learning about staining composite materials is important for maintaining a polished look. With the right products and preparation, you can refresh your deck, protect it, and extend its life without costly replacement.
Understanding Composite Decking Materials
Composite decking combines wood fibers with plastic, creating durable boards that resist rot and pests.
-
Uncapped composite material: Early-generation boards are more porous, absorb stains easily, and can often be refinished with wood stain or specialized coatings.
-
Capped composite decking: Modern boards include a protective coat or shell. This outer layer protects against fading but makes it harder for stains or paint composite products to adhere.
In Washington, capped composite materials are popular because they protect decks from damp weather and help maintain outdoor living spaces with minimal upkeep. Most composite decking can last 25–30 years with proper care.
Can You Stain Composite Decking Successfully?
One of the most common questions homeowners ask is, can you stain composite decking successfully? The answer depends on the type of boards installed.
-
Older uncapped composite deck boards can be lightly sanded and stained composite finishes may bond successfully.
-
Capped composite boards are designed to resist coatings, making staining composite surfaces nearly impossible.
-
Always check manufacturer guidelines, since refinishing may void warranties.
What Are the Signs Your Composite Deck Needs Refinishing?
-
Faded color that looks uneven across boards
-
Surface scratches or stubborn stains
-
Weather damage from sun and Washington’s heavy rainfall

Step-by-Step Guide to Staining Composite Decking
Cleaning and Preparation
-
Sweep debris and wash with a composite deck cleaner to remove algae and mildew.
-
Rinse thoroughly and allow decks to dry completely.
Choosing the Right Stain for Composite Surfaces
-
Select a high-quality water-based stain composite product labeled safe for composite materials.
-
Avoid oil-based wood stains that may peel or fail on capped composite.
Applying Stain Evenly in the PNW Climate
-
Apply thin coats with a roller or sprayer for even coverage.
-
Do not over-apply stain, as too much coat can leave residue.
Drying Time and Weather Considerations in Tacoma & Kitsap
-
Ensure at least 48 hours of dry conditions before and after applying stains.
-
Avoid staining during rain or when exterior temperatures are extreme.
How Much Does It Cost to Stain Composite Decking in Washington?
Washington homeowners often wonder not only can you stain composite decking but also how much it costs.
-
DIY Costs: $100–$250 for cleaning materials, stain, brushes, and deck cleaner.
-
Professional Costs: $2–$5 per square foot, depending on project size and prep work.
-
Factors: Deck accessibility, condition of composite boards, and required coats of finish.
In Tacoma, Bremerton, and Gig Harbor, professional staining composite services typically cost $600–$1,200 for medium decks.
Alternative Options to Staining Composite Decking
Can You Paint Composite Decking Instead?
Yes, but painting composite surfaces rarely lasts more than a year in Washington’s rainy climate. Paint composite coatings peel easily, especially on capped composite boards.
Refreshing with a Deck Cleaner or Restorer
A composite deck cleaner or brightener can remove stains, refresh colors, and protect materials without applying wood stain or paint.
Replacing Damaged or Severely Faded Boards
When boards are beyond repair, replacing composite materials may be more cost-effective than repeated staining projects.
