When it comes to creating a beautiful, long-lasting outdoor space, Merbau decking remains one of the most popular choices among homeowners and builders alike. Known for its rich reddish-brown tones, durability, and resistance to harsh weather, Merbau can transform any backyard into an elegant retreat. However, to preserve its natural beauty and strength, proper oiling and sealing are essential.
In this guide, we’ll walk you through how to oil and seal your Merbau decking for maximum durability while also covering key considerations if you’re comparing Merbau decking Melbourne prices or choosing the right board sizes like Merbau Decking 140 x 19, Merbau Decking 90 x 19, or Merbau Decking 70 x 19.
Why Oiling and Sealing Merbau Decking Matters
Merbau is a dense hardwood, but like any natural timber, it’s still exposed to sunlight, rain, and foot traffic. Without proper care, your deck can fade, dry out, or even crack over time. Oiling and sealing:
Enhances colour – Brings out the deep, rich tones of Merbau.
Prevents moisture damage – Reduces swelling, shrinking, and warping.
Protects against UV rays – Minimises fading from the Australian sun.
Extends lifespan – Keeps your deck looking new for many years.
Step-by-Step Guide to Oiling and Sealing Merbau Decking
1. Choose the Right Oil or Sealer
Opt for a high-quality decking oil specifically designed for hardwood timbers. Penetrating oils work best as they nourish the wood from within. If you’re in Melbourne, local suppliers often stock products matched to the climate.
2. Clean the Deck Thoroughly
Before oiling, sweep away dirt, leaves, and dust. Use a deck cleaner to remove any built-up grime or tannins that naturally bleed from Merbau. Allow the surface to dry completely.
3. Sand for a Smooth Finish
Lightly sand the surface to remove rough spots and open the timber’s pores. This step ensures the oil penetrates more effectively.
4. Apply the First Coat of Oil
Use a brush, applicator pad, or roller. Work along the grain of the timber for an even finish. Avoid over-applying, as excess oil can leave a sticky residue.
5. Allow Drying Time
Let the first coat dry fully—usually 6–12 hours depending on the product and weather conditions.
6. Apply a Second Coat
Two to three coats are recommended for new Merbau decking. Each coat adds more protection and enhances the depth of colour.
7. Regular Maintenance
Reapply oil every 6–12 months, depending on exposure to the elements. High-traffic areas or decks around pools may need more frequent care.
Choosing the Right Merbau Decking Size
When planning your deck, board size plays an important role:
Merbau Decking 140 x 19 – Wide boards ideal for large, open decks with a premium look.
Merbau Decking 90 x 19 – A popular option for standard residential projects, offering a balance of cost and aesthetics.
Merbau Decking 70 x 19 – Narrow boards perfect for feature areas, pathways, or smaller spaces.
If you’re comparing Merbau decking Melbourne prices, the size you choose will directly impact cost. Wider boards usually come at a higher price point but reduce installation time.
