Few things are as inviting as a wooden deck. It’s where we gather with family on summer evenings, enjoy braais with friends, or relax with a cup of coffee in the morning sun. But over time, the harsh South African climate leaves its mark. Sunlight fades the timber, rain and moisture cause it to grey, and foot traffic wears away its once-pristine finish. When the time comes to revive your deck, one of the most significant decisions you’ll face is whether to protect it with varnish or oil.At Prominent Paints, we’ve walked this journey with countless DIY enthusiasts and contractors. Both options have their place, but when it comes to outdoor decking, oils often take the lead. Let’s explore why.
Varnish: A Classic but Demanding Choice
For decades, varnish has been the go-to for wood protection. Products like Prominent Woodpro Wood Varnish form a clear, protective film that enhances the grain while giving a polished, glossy finish. On covered furniture, doors, or indoor timber, varnish offers durability and a touch of elegance.
Outdoors, however, varnish tells a different story. The very film that protects the wood also creates a brittle layer that struggles against our climate. The blazing UV rays of summer eventually cause the varnish to crack, peel, and flake away. Once that happens, maintenance becomes a chore: you’ll need to sand the deck back to bare wood before you can reapply. For many DIYers, this is a labour of love that quickly loses its charm.
Oils: Nourishment from Within
Decking oils take a gentler, more natural approach. Instead of sitting on the surface, oils penetrate deep into the timber, replenishing its natural oils and protecting it from within. They bring out the richness of the wood while leaving a natural, matte finish that feels authentic and welcoming.
The real beauty of oils lies in their flexibility. Because they move with the wood, they don’t crack or peel. Recoating is refreshingly simple: clean the deck, apply another coat, and you’re done. There’s no need for back-breaking sanding or stripping. Regular touch-ups keep the deck nourished and resilient against rain and sun. While oils may not last quite as long as varnish before reapplication, the ease of maintenance makes them a favourite among DIYers who want results without a marathon of prep work.
Why Oils Usually Win Outdoors
South Africa’s climate is tough on timber. Between intense UV rays, dramatic seasonal shifts, and summer downpours, decks need more than just a surface shield — they need a breathable, flexible solution. Oils provide just that. They age gracefully, deepen the timber’s natural beauty, and allow homeowners to maintain their decks with minimal fuss. For these reasons, oils usually come out on top in the great “oil vs. varnish” debate when it comes to exterior use.
DIY Tips for a Successful Deck Revival
If you’re ready to bring your deck back to life, here are a few practical steps:
- Preparation matters: Start with a clean slate by using a deck cleaner to remove old coatings, dirt, and mildew.
- Light sanding: Smooth any rough patches for a uniform finish.
- Apply with care: Brush or roll the oil along the grain, ensuring even coverage. Wipe away excess to prevent sticky spots.
- Maintain annually: A fresh coat once a year will keep your deck looking beautiful and protected against the elements.
