Deck Staining & Oiling Melbourne

Melbourne's variable climate can be tough on timber decks. Proper staining or oiling protects your deck from UV damage, moisture, and wear while enhancing its natural beauty. This guide covers everything you need to know about deck finishing.

Deck Oil vs Deck Stain: What's the Difference?

Deck Oil

Penetrating oils soak into the timber:

• Enhances natural timber grain
• Provides a natural, matte finish
• Easier to maintain and recoat
• Needs more frequent reapplication (annually)
• Best for: Hardwoods like Spotted Gum, Merbau

Deck Stain

Stains sit on the surface with some penetration:

• Available in various opacity levels
• Better UV protection
• Can change timber colour significantly
• Longer lasting (2-3 years)
• Best for: Softwoods, older timber, colour change

Types of Deck Finishes

Clear/Natural Oil

• Shows natural timber colour
• Minimal colour change
• Requires more frequent maintenance

Tinted Oil

• Enhances timber colour
• Better UV protection than clear
• Popular for restoring greyed timber

Semi-Transparent Stain

• Allows grain to show through
• Good UV and moisture protection
• Available in many colours

Solid Stain/Deck Paint

• Completely covers timber grain
• Maximum protection
• Best for hiding imperfections
• Paint-like appearance

Preparing Your Deck

Step 1: Clean Thoroughly

• Remove furniture and planters
• Sweep away debris
• Use deck cleaner to remove dirt and mildew
• Pressure wash (careful not to damage timber)

Step 2: Let Dry Completely

• Allow at least 48 hours drying time
• Timber must be completely dry
• Check moisture with a meter if unsure

Step 3: Sand if Necessary

• Remove old flaking finish
• Smooth rough or splintered boards
• Open timber pores for better penetration

Application Tips

• Weather: Apply on a mild, dry day (15-25 degrees)
• Timing: Avoid direct sunlight - morning or late afternoon
• Tools: Use a deck brush, roller, or pad applicator
• Direction: Work along the grain
• Coverage: Don't over-apply - oils should penetrate, not pool
• Coats: Most products need 2 coats

• Autumn (March-May): Ideal - mild temps, low humidity
• Spring (September-November): Good, but watch for spring rain
• Summer: Possible early morning, avoid hot days
