Cedar is famous for its beautiful aesthetic appeal, long life span, excellent thermal insulator properties and resistance to rot, insects, and decay. Because of these amazing qualities, cedar is widely used in New Zealand for cladding and sometimes for fencing and louvres.
While cedar is a great quality timber, it still needs regular maintenance to keep it looking its best. This is especially true when it comes to cedar cladding because it’s constantly exposed to New Zealand’s harsh sun, humidity, rain and snow. So, without proper care, your cedar cladding will eventually start to degrade and become discoloured or warped.
But, the good news is, you can stop this or slow it down, and we’re here to show you how with this ultimate guide to cedar cladding maintenance.
We’ll unpack the ins and outs of cedar maintenance in New Zealand, which will include;

A regular maintenance schedule will help cedar last for years.
New cedar cladding: For newly-installed cedar cladding, apply a high-quality wood oil like Dryden WoodOil, which is a clear, water-repellant, migrating oil that helps protect the timber from the inside out.
If you want to add colour to your cedar cladding, add Dryden Colourtone+, which would also give it enhanced UV protection.
After one year: We highly recommend giving your cedar cladding an annual soft wash which means just washing it down gently with a garden hose. If there is a bit of dirt, gently wash it off with a bit of detergent.
After two or three years: Re-apply Dryden WoodOil with or without Dryden Colourtone+ as needed, focusing on areas where the colour has faded.
Ongoing maintenance: Continue inspecting, cleaning, and reapplying Dryden WoodOil with or without Dryden Colourtone+ every two-to-three years or as needed, based on your cedar cladding’s appearance and condition.
Give a soft wash: The standard way to clean your cedar cladding is with a soft wash which we recommend doing annually. Just use a garden hose and gently rinse off any dirt or grime. Use detergent if you need to get rid of dirt.

How does it maintain your cedar cladding? As a migrating oil with water-repelling properties, Dryden WoodOil helps prevent the absorption of water into your cedar, reducing excessive warping, cupping, and splitting of timber and extending the lifespan of your cedar cladding.
How does it maintain your cedar cladding? Dryden Colourtone+ provides UV protection and helps prevent the timber from silvering when maintained correctly.
How to use it: Choose from over 37 colours and add the selected stain to Dryden WoodOil. Then carry out the same application method.
Silvering – This happens when coloured timber extractives are washed out (leaching), and the cedar structures get damaged by sunlight (photodegradation).
Dryden WoodOil helps cedar maintain a grey look, so it may not mean that your cladding needs re-oiling or coating in this specific case. Silvering only indicates the need for coating and colour when you want to maintain a natural or stained look.
As a simple answer, what we can say is that if you want a clear/transparent oil to maintain your cedar’s natural colour, go for Dryden WoodOil. If you want more colour and enhanced UV protection, add Dryden Colourtone+ to Dryden WoodOil.
At Dryden, we often get asked whether it’s better to oil or stain cedar cladding, and it’s a tough question to answer. Instead, let’s reframe it to be more specific: should I use oil or a traditional stain on cedar? In our terms, staining means adding colour. So, when you use a combo of Dryden WoodOil + Colourtone+, you’re essentially staining the timber. This is why it comes down to your preference for the look and finish you want on your cedar cladding.
In summary, cedar cladding requires maintenance and regular upkeep to keep it looking great and last for a long time. By using Dryden WoodOil or Dryden Colourtone+ added to Dryden WoodOil, you can help extend the life of your cedar cladding by preserving its natural finish and providing protection from UV rays, rain, snow, hail and wind damage.
