The deck stain coverage formula

Gallons of stain = (Deck sq ft × Number of coats) ÷ 200

One gallon of deck stain covers about 200 sq ft on smooth wood and 150 sq ft on rough or weathered wood. Most decks need 2 coats — the first soaks in, the second seals. Don't forget to factor in railings, balusters, and stair stringers — they typically add 25 to 40% more surface area than the deck floor alone.

Worked example — 300 sq ft deck with railings

1. Floor area: 300 sq ft
2. Railings + balusters + stairs: 300 × 0.35 = 105 sq ft
3. Total stainable surface: 405 sq ft
4. Two coats: 405 × 2 = 810 sq ft of coverage needed
5. Gallons: 810 ÷ 200 = 4.05 → buy 5 gallons (always round up)
6. Cost at $45/gallon = $225 in stain alone

Cost by stain type (2026 prices)

• Clear sealer — $25 to $40 per gallon · lasts 1 to 2 years
• Transparent stain — $30 to $45 per gallon · lasts 1 to 2 years
• Semi-transparent stain — $35 to $55 per gallon · lasts 2 to 4 years
• Semi-solid stain — $40 to $60 per gallon · lasts 3 to 5 years
• Solid color stain — $40 to $65 per gallon · lasts 4 to 7 years
• Oil-based premium (Penofin, Cabot, Sikkens) — $55 to $90 per gallon

Semi-transparent is the sweet spot for most homeowners — it shows the wood grain, hides minor weathering, and lasts twice as long as a clear sealer for only a few dollars more per gallon.

Prep work — where 80% of the quality lives

1. Sweep and clear the deck — remove furniture, planters, grills
2. Inspect and replace any rotten or split boards
3. Hammer down or replace popped nails and loose screws
4. Apply deck cleaner (or stripper for old solid stain) — let dwell 10 to 15 minutes
5. Pressure wash at 1,200 to 1,500 PSI with a 25° tip, working with the grain
6. Apply wood brightener to neutralize and even the color — rinse
7. Let the deck dry 48 to 72 hours — moisture meter should read under 15%
8. Lightly sand any raised grain with 60 to 80 grit
9. Stain on a dry, overcast day between 50°F and 90°F

Factors that increase the cost

• Stripping old solid stain or paint — adds $1 to $2.50 per sq ft
• Deck height above 8 ft (scaffolding or ladder work) — adds 15 to 25%
• Intricate railings, lattice, or pergola — adds 20 to 40%
• Replacing boards before staining — $5 to $15 per linear ft
• Premium oil-based or marine-grade stain — adds $20 to $40 per gallon
• Rush job (under 1 week scheduling) — adds 10 to 20%

How often should you re-stain a deck?

The water test tells you. Sprinkle water on the deck — if it beads up, the seal is still good. If it soaks in within 10 seconds, it is time to re-stain. As a rule of thumb: clear sealer every 1 to 2 years, semi-transparent every 2 to 3 years, semi-solid every 3 to 5 years, solid every 5 to 7 years.

DIY vs hiring a pro — when each makes sense

• DIY makes sense — decks under 400 sq ft, simple layouts, you own a pressure washer
• Hire a pro — multi-level decks, stripping old paint, second-story decks, decks over 600 sq ft
• Average savings DIY — $400 to $1,200 on a 300 sq ft deck
• Average time DIY — 1.5 to 2 weekends (1 prep, 1 stain)

Regional price differences (2026)

• Northeast & Pacific (NYC, Boston, SF, Seattle) — $3.50 to $5.50 per sq ft
• Midwest (Chicago, Minneapolis, Detroit) — $2.25 to $4.00 per sq ft
• South (Atlanta, Dallas, Charlotte) — $2.00 to $3.75 per sq ft
• Mountain & Southwest (Denver, Phoenix) — $2.25 to $4.25 per sq ft

FAQ — deck staining cost

Is it cheaper to stain or paint a deck?

Stain is cheaper short-term and easier to refresh — paint costs about 20% more upfront and is far harder to redo because it must be fully stripped, not just recoated. Stain is the better long-term value on horizontal deck surfaces.

Can I stain a wet deck?

No. The deck must be fully dry (under 15% moisture content) or the stain will not penetrate, leaving a blotchy finish that peels in months.

How long does deck staining take?

A pro crew finishes a 300 sq ft deck in 1 to 2 days including prep. DIY takes a full weekend: half a day to clean, 48 hours to dry, then 4 to 6 hours to stain two coats.

Do I need a permit to stain my deck?

No — staining is maintenance, not construction. No permit required in any U.S. jurisdiction.
