Western Washington’s climate is one of the hardest on wood decks in the country — long wet winters, UV-intense summers, and rapid mold growth in shaded areas. Choosing the right coating and applying it correctly can add 5–10 years to a wood deck’s life. Here’s what works in the Puget Sound.
The Three Coating Categories
Penetrating Sealers (Clear or Semi-Transparent) Penetrating sealers soak into the wood fibers rather than forming a surface film. They preserve the natural look of the wood and are easier to maintain — you apply a new coat without stripping the old one.
Best for: New cedar, pressure-treated, or redwood decks where you want a natural look.
Top products for PNW: Armstrong Clark Semi-Transparent, Defy Extreme Wood Stain, TWP (Total Wood Preservative).
Solid Stains and Paints Solid stains form a pigmented film over the wood. They hide grain and color variation — useful for older, weathered decks. They provide more UV protection than penetrating stains.
Downside: They peel. In a wet climate, a solid stain applied over a deck with any trapped moisture will peel within 1–2 seasons. They also require stripping before recoating.
Deck Resurfacers Products like Rust-Oleum Deck Restore or Behr Advanced Deck Resurfacer fill cracks and gouges with a thick, textured coating. They can make an old deck look significantly better.
Best for: Older decks with surface damage that aren’t ready for full replacement. Not a substitute for structural repair — if boards are soft or posts are rotted, resurface won’t save the deck.
Cost to Refinish a Deck in Seattle
| Service | Cost (400 SF deck) |
|---|---|
| Pressure wash + clean | $300–$600 |
| Strip old coating (if needed) | $400–$800 |
| Apply penetrating stain (1 coat) | $600–$1,200 |
| Apply solid stain / paint (2 coats) | $900–$1,800 |
| Full refinish (clean + strip + 2 coats) | $1,200–$2,500 |
When to Recoat vs. When to Replace
Signs it’s time to refinish (not replace): – Surface graying and slight checking – Peeling or flaking coating – Water no longer beads on the surface
Signs it’s time to replace: – Soft, spongy boards (probe with a screwdriver — if it penetrates easily, the board is rotted) – Structural framing showing rot or insect damage – Boards over 20 years old with widespread cracking

They soak into the wood rather than forming a film, so they don't peel in the wet winters. They're also easier to maintain — just clean and recoat every 2–4 years without stripping."
