Cedar is a miracle timber if ever there was one. It’s a better insulator than brick or concrete, it keeps noise out, is highly durable and - as every Cedar homeowner can attest - it looks stunning and unique.

Cedar is a miracle timber if ever there was one. It’s a better insulator than brick or concrete, it keeps noise out, is highly durable and – as every Cedar homeowner can attest – it looks stunning and unique. 

At TimberTech, we genuinely believe that Cedar is a remarkable cladding material. 

In this article, we want to share what makes Cedar such an effective cladding, and highlight some little-known facts about this amazing timber. 

If you own a Cedar home, or are looking to buy a Cedar home, rest assured that Cedar is one of the best claddings around. 

1. Cellular Structure 

Cedar is designed to move, with deep pores that allow moisture in and out without damaging the stability of the timber. 

This means that in the summer, when the hot sun is sucking moisture from the timber and causing it to contract, Cedar can move with minimal cracking. 

And in the winter, when Cedar gets wet and starts to expand again, it does so without cupping and warping, which are problems that come with other timbers. 

2. Deep Pores

Those deep pores we mentioned, they are also genius at holding stains and oils. 

This is important for extending the life of the timber and keeping it looking fresh and vibrant. 

New Zealand has strong UV rays that will break down any type of coating applied to a house and suck out the natural oils, eventually drying out the timber and leading to roughening of the surface and fine cracks (which is called “surface checking” in the industry). 

Regular oiling will prolong the beautiful look and weather resistance of your Cedar by penetrating deeply through the Cedar’s open cellular structure and replacing the natural oils lost over time. 

3. Ease of Maintenance 

Like any building material exposed to the elements, Cedar needs maintenance both to protect the internal structure of the house, and to keep it looking cosmetically beautiful. 

This isn’t a downside, just an unavoidable part of owning a house. 

With Cedar you don’t have to constantly maintain the whole house, just the areas that are exposed to the sun. 

For most Cedar homes, this means recoating sun-exposed areas every 2-3 summers. The sheltered faces of a Cedar home are very low-maintenance and will only need recoating 2-3 times over a 15-year period. 

4. Durability & Insulation 

Cedar is a superior insulator compared to other weatherboards, letting the house breath over summer, and keeping the warmth in over winter. It also dries very quickly because the timber is so porous and rich with pores. 

On a side note, regularly maintaining your Cedar will help improve the energy efficiency of your home. Adding oil to the boards keeps them flat and stops the cold getting in, and the heat getting out. Boards that have been oiled will also cause rain to bead from the surface and keep the internal structure of the house dry. 

Cedar also has its own mould and fungal inhibitors within the timber to stop rot and nasties from getting established. 

5. Cedar Just Looks Stunning 

Let’s put the amazing properties of Cedar to one side and talk about how good it looks.  

A well-maintained Cedar home has a timeless look. As the timber ages, it will naturally weather, getting etched by the sun, rain and elements to have a beautiful rustic look. 

Colour wise, Cedar can be anything from blonde-yellow to deep Mahagony red, which lends itself to a unique aesthetic quality. There are no two Cedar weather boards that are the same. Some have lots of grain, some are very plain, but when oiled, each will have a different appearance. 

Because the oil is translucent, it works with the underlying tones of the Cedar. And because stains and oil come in different colours, the final colour is always a unique blend, and always interesting to look at.

Many Cedar homeowners fall in love with the Scandinavian silvered look – minimalist, clean, with a silver sheen that accentuates the beauty of the timber and the natural surroundings.

Many Cedar homeowners fall in love with the Scandinavian silvered look – minimalist, clean, with a silver sheen that accentuates the beauty of the timber and the natural surroundings.

But when it comes to achieving this look, there is a common misconception that all you need to do is leave the Cedar and silvering will happen naturally. Unfortunately, this is not true, at least in the New Zealand climate, and timber that is left to silver will eventually turn unsightly.

In this article we will cover what silvering is, how you can silver your Cedar safely while still protecting the timber, and some DIY tips for maintaining the silver look of your Cedar until you are ready to oil.

Is Silvering Bad for Cedar? 

Without taking the location and climate into consideration, silvering itself is not bad for the timber. Silvering is caused by exposure to UV rays, which fray and loosen the top cells of the Cedar and cause the surface to become bleached.

In colder climates this isn’t a problem as the lower temperatures kill off the bacteria, retaining the beautiful, silvered look. But in a warm and wet climate such as ours, bacteria and mould will get caught in the roughened surface, and quickly turn the Cedar black.

Even if the mould and bacteria are removed, the natural silvering effect will often look patchy and uneven, detracting from the natural beauty of the timber.

Silvering Cedar the Right Way

So, is there any way to have the silver look you love, while still protecting your cladding? The answer is a resounding “Yes!”

Wood-X is a deep penetrating wood oil developed with Resene. It comes in a range of exciting colours – from rich reds and bush greens to a daring indigo blue – and a whole range of wood-protecting silvers. Applying a silver-tinted oil will protect your timber from the harsh UV rays, allow it to silver more quickly and give a more consistent silver look.

After applying the silver-tinted oil, you will need to follow a regular maintenance schedule to keep your Cedar looking its best. We recommend a soft wash every year, followed by recoating exposed areas every 2-3 summers.

DIY Silvering Maintenance

If you are not ready to oil your cladding quite just yet, a more affordable solution is to spray your house with a slow-acting mould and fungal killer such as Wet and Forget. This will remove the organic bacteria from the surface, but it will not replenish the natural oils of the Cedar or protect it against splitting and cupping in the future.

If you do not plan on oiling or staining your house, another option is to leave the silvering on as it provides natural protection to the layer below it. You can then use a slow-acting mould and fungal killer to keep it looking clean. The downside to this approach is that the timber will eventually look aged and tired.

Get Professional Advice You Can Trust

Ultimately, the best approach for protecting your cladding AND getting the silvered look is to oil your Cedar with a silver tinted oil. If you are unsure about the best approach and would like to talk with an expert, call us on 0800 298 298.
