3 Best Products for Kwila Maintenance in New Zealand

The products you use on your Kwila deck for maintenance can have an impact on the longevity of your outdoor space. That’s why it’s important to ensure you use the right products at the right time of your Kwila deck maintenance journey. Using products that are tried and tested for New Zealand’s unique climate and environment is also of utmost importance.

Dryden Timbercare products proudly carry the ‘New Zealand Made’ label as they are built to withstand the strong sun, humidity and rain experienced here in Aotearoa. This comprehensive guide outlines three different types of products available for Kwila maintenance from Dryden that can be used to clean, oil and stain your Kwila deck.

Understanding Kwila: Why Choose Kwila For Decking?

Kwila is a fantastic choice for decks because it is a premium, high-density hardwood that has a beautiful yellow-brown/ dark-red-brown tone. Also known as Merbau, Kwila is a bit more expensive than other common timber types like Radiata Pine. But it’s well worth the investment and here’s why:

  • Merbau/Kwila is naturally resistant to termites, fungi and decay.
  • Requires minimal maintenance and can be cleaned with a soft wash using your garden hose.
  • Highly durable and can handle NZ’s harsh weather conditions
  • Great for high-traffic outdoor areas like decks because of its resistance to scratches, dents and wear.
  • Very dense timber that’s less prone to cracking.

Does Kwila need to be oiled?

Yes, although naturally rich in protective oils, your Kwila deck needs to be oiled and maintained regularly to stay strong and decay-free. If not maintained properly, your Kwila will suffer from;

  • Fading – NZ’s harsh UV rays can bleach your deck, resulting in a dull grey or silver colouring.
  • Mould and mildew – The humid climate of New Zealand encourages mould and mildew growth, which can discolour your Kwila decking
  • Warping, cupping, and splitting

That’s why you need to maintain your Kwila decking with the right products regularly.


What Maintenance Does Kwila Decking Need?

Start with a good coating of OilStain, Dryden’s premium Kwila decking oil and follow up with a wash and visual inspection every twelve months. Moisture is the biggest enemy of a Kwila deck, so you need a water-repellent coating like OilStain to prevent water damage, which comes in the form of warping, splitting and mould growth.

If you need enhanced UV protection, add Colourtone+ to Dryden OilStain – this is a tinted oil with added UV protection that is available in 37 colours.

  • It’s important to note that if you apply Dryden OilStain on its own as a clear base, your timber will silver naturally. Some people like the silvered, grey look, but others prefer to maintain Kwila’s yellow-brown/ dark-red-brown or change the colour, so they add a stain to it. This brings us to the next product…


3. Kwila Deck Stain: Dryden Colourtone+ with Dryden OilStain
