Best Deck Stains & Sealers for 2026

Start with the finish type, not the brand

Picking a deck stain is really two decisions: how much wood grain do you want to see, and how much maintenance are you willing to do. Get those right and any reputable brand will perform. Get them wrong and even the best product will peel in a year.

Clear sealers — natural look, most maintenance

A clear sealer (like Thompson's WaterSeal or Ready Seal Natural) preserves the raw wood color and adds waterproofing but no UV protection. Expect to reseal every 12–18 months. Best for cedar or redwood decks where you love the fresh-cut color and don't mind the annual routine.

Semi-transparent stains — the sweet spot

Semi-transparent penetrating stains add color and UV protection while still letting the wood grain show through. This is what most decking pros use on pressure-treated and cedar decks. Standouts:

• Ready Seal — the professional favorite. No lap marks, no back-brushing, and no film to peel. Just clean, apply, and walk away. Lasts 2–3 years in most climates.
• Cabot Australian Timber Oil — the go-to for cedar and hardwoods. Rich amber tones and deep penetration on dense woods like ipe.
• TWP 100/1500 Series — favored on the West Coast. Reapplies without stripping.

Solid stains — most protection, least grain

Solid stains look like thin paint and completely hide the wood grain. They deliver the longest UV protection (4–7 years) but form a film — meaning when they fail, you'll need to strip or sand before recoating. Best for older decks with mismatched or damaged boards where you're prioritizing coverage over natural look.

• Behr Premium Solid Color Waterproofing Stain & Sealer — Consumer Reports' longtime top pick.
• Sherwin-Williams SuperDeck Solid — pro-grade, wide color range, holds up in harsh sun.

How to actually apply it (and not screw it up)

1. Wait for new pressure-treated wood to dry. Fresh PT is saturated with preservative — stain won't penetrate. Wait 4–8 weeks, or until a water droplet soaks in within 60 seconds.
2. Clean and brighten. Use a deck cleaner (percarbonate-based) followed by a wood brightener (oxalic acid). This restores pH and opens the pores.
3. Pick a mild day. 50–85°F, no direct sun on the boards, no rain in the 24 hours after.
4. Apply thin coats. More stain does not equal more protection — puddled stain peels. Wipe off anything that hasn't absorbed in 15 minutes.
5. Back-brush. Even if the label says "no back-brushing required," a light brushing evens out lap marks on horizontal boards.

How much stain will you need?

A rough rule of thumb: 1 gallon per 250 sqft of new smooth wood, or 1 gallon per 175 sqft on weathered wood. That includes deck boards, railings, and stair treads. Get an exact estimate — including cost — with our deck stain calculator.

Don't skip the cleaner and brightener

Every deck stain manufacturer publishes performance data assuming you started with a properly prepped surface. Skipping cleaner/brightener is the single biggest reason stains fail early. A $30 jug of Restore-A-Deck or Defy cleaner adds one afternoon and doubles the life of your stain job.

Bottom line

For most homeowners with a pressure-treated or cedar deck: Ready Seal semi-transparent is the lowest-effort winner. For hardwood or premium cedar: Cabot Australian Timber Oil. For an old, patched-together deck you want to hide: Behr Premium Solid. Whatever you pick, budget for cleaner and brightener too.
