Preparing Your Deck for Staining
Clean the Deck Surface
A clean deck surface is essential for stains to adhere properly. Start by using a deck cleaner and follow these steps to clean a deck before staining:
- Remove any furniture and debris.
- Use a stiff brush or pressure washer to apply the deck cleaner, reaching between boards.
- Allow it to dry for 24–48 hours.
Sanding the Deck
If your deck has old stain, splinters, or rough patches, sanding a deck before staining smooths the wood and helps the stain absorb evenly. Consider deck sanding sponge or a power sander for larger areas.
- Sand the surface until it’s smooth, focusing on rough spots.
- Vacuum or brush away dust after sanding.
Choosing the Right Deck Stain
The choice between oil-based and water-based deck stain can impact durability and maintenance. Here’s what you need to know to find the best stain for deck floor protection:

Applying Deck Stain - Methods & Tips
Calculating How Much Stain You’ll Need
Use our stain coverage calculator to determine how much stain you need for your deck. Typically, one gallon covers about 250-350 square feet, depending on wood type.
Applying the Stain
When it’s time to apply the stain, choose the best way to stain a deck by considering your tools. Each application method provides unique advantages for different deck designs and stain types.
- Brush or Pad Applicator: Use a deck stain brush or pad for precise, even coverage on flat boards.
- Roller: A deck stain roller covers large areas quickly.
- Paint Tray: A heavy duty paint tray can be used with extension poles to help with large projects.
Deck Staining Tips for a Professional Finish
Applying Between Deck Boards
Make sure to reach between boards for complete coverage. Use a small brush to stain between deck boards if your applicator can’t reach.
Applying Multiple Coats
Most decks need one to two coats. Be mindful of drying time between coats—wait 24 hours between applications for the best results. Check the label for specifics on drying time and how long stain should dry before walking on it.
Post-Staining Maintenance and Care
How Often to Stain Your Deck
Plan to stain your deck every 2-3 years, depending on the climate and wear. Regular maintenance helps keep your deck looking new and protects it from weathering.
How to Remove Stain from Decking
