The applicator decides how evenly the stain goes on and how much ends up on the siding or the grass. Pads on a pole are fast on deck boards, brushes push stain into the grain and the ends, sprayers reach spindles and lattice quickly, and rollers cover smooth new boards. Most decks are best done with two of them: one for the boards, one for the rails.
Below, each tool is compared by where it works best, and the stain quantity comes from our deck stain calculator. Always follow the stain maker's instructions — some penetrating stains say not to back-brush, while others require it.

How much stain a 300 sq ft deck takes
Buy the stain before the tools so the job is not stopped halfway. The example uses the deck stain calculator with 200 sq ft per gallon per coat; read the can for your product's coverage, which varies with the wood's age and roughness.
Worked example: 300 sq ft of deck, two coats at 200 sq ft per gallon
- Total area coated: 600 sqft
- Exact amount: 3.0 gal
- Buy as: 3 × 1 gal
3 gal of stain — add rails and stairs separately, since spindles take far more stain per foot than boards.

Which tool for which part of the deck
| Surface | Best tool | Tip |
|---|---|---|
| Deck boards | Stain pad on a pole, or roller | Work two or three boards at a time along their full length to avoid lap marks |
| Board gaps and ends | Brush | Do the ends and the gaps first, then the faces |
| Rails and spindles | Pump sprayer, then a brush | Mask the siding and spray from above |
| Stair treads and risers | Brush or small pad | Start at the top and work down |
| Rough or weathered wood | Brush (back-brush after pad or sprayer) | Rough wood drinks more stain — check coverage |
Prep that matters more than the tool
- Clean the deck with a deck cleaner or brightener and let it dry for as long as the stain maker requires — usually at least a day or two.
- Sand or wash off raised grain and old flaking finish; new stain does not bond to failing stain.
- Check the weather: no rain for the cure time stated on the can, and not in direct midday sun on hot days.
- Stir the stain often so pigment does not settle; mix all cans together if you bought several.
Safety notes
- Rags soaked in oil-based stain can catch fire by themselves as they dry: lay them flat outdoors to dry or store them in a sealed metal can of water, as the label directs.
- Wear gloves, eye protection and, when spraying, a respirator suited to the stain's solvent.
- Keep sprayers away from open flames and pilot lights, and cover plants and the house siding before spraying.
Frequently asked questions
What is the best way to apply deck stain?
For most decks, a stain pad or roller on a pole for the boards and a brush or pump sprayer for the rails, then back-brush if the stain maker recommends it. Do the gaps and board ends first.
Is it better to spray or brush deck stain?
Spraying is faster, especially on spindles, but it wastes stain and needs masking. Brushing works the stain into the wood more evenly. Many people spray, then back-brush.
Can I use a paint roller for deck stain?
Yes, on smooth boards and for solid-colour stains. On rough wood a roller can leave stain sitting on the surface, so back-brush to work it in.
How much deck stain do I need?
Divide the area by the coverage per gallon on the can and multiply by the number of coats. A 300 sq ft deck at 200 sq ft per gallon with two coats takes three gallons; the deck stain calculator does it for your numbers.
Should I sand my deck before staining?
If the wood is weathered, has raised grain after washing or the old finish is flaking, yes. New, dry wood that absorbs water well usually just needs cleaning.
