Transitioning Cedar from Stain to Oil

Transitioning Cedar from Stain to Oil

13 Jul 2023
Cedar Stain To Oil Before 1

As Cedar ages, we highly recommend transitioning Cedar from stain to a penetrating oil where possible.

If you want to know more about the pros and cons of each, please read our article The Cedar Oil vs. Cedar Stain Debate.

The simple truth is, no matter how much stain you put on the surface of the timber, 5-10 years of sun exposure on a northern face will deplete the natural oils of the Cedar and cause the boards to dry out, cup, then ultimately split.

This doesn’t just look bad, it threatens the integrity of your home to withstand the elements and if the damage continues, you may need to replace the cladding altogether.

How Stained Cedar Ends Up Looking Unsightly

Treating aged Cedar with stain isn’t usually an informed choice by the homeowner. Often, the previous owner has done a quick fix and used stain to make the Cedar look pretty before selling, or the current homeowner has stained over a poorly prepared stain without stripping back the boards.

Stains are translucent, so even though they have some opacity, you can still see through them and unless the preparation is done well, stains don’t hide imperfections.

Eventually the stain will delaminate in the harsh UV, giving a camouflaged look with light and dark shades that are often patchy and uneven.

The Transition Process from Stain to Oil

First, we will do a site visit to look at the current state of the Cedar boards.

In the best-case scenario, the weatherboards will have had an even exposure to the sun. We then use a strong solution of the oxy cleaner to get in behind any of the oxidised stain which has been broken down by the sun, then use a heavy wash to remove anything which is loose.

The heavy wash will give us a good look at the condition of the boards below. If there is any stain remaining on the surface, we will need to sand or strip the boards back to their virgin state before applying the oil.

If the boards have had partial shade cover, such as nearby trees or soffits that have only protected the upper areas, they need to be stripped. You can’t just oil over the top and hope that it’s going to match the weatherboards below.

This adds a lot of cost to the process and if the homeowner isn’t willing to spend that much money, we may recommend applying another coat of stain to provide at least some protection and keep the house looking tidy.

Be Prepared for the Shiny-flat Look

One of the biggest downsides of moving from stain to oil is a 3-9 month transition period where your Cedar will have a shiny-flat-shiny-flat look.

This happens when oil is applied to any surface that still has stain remnants. The oil cannot soak through the stain as it is non-porous, so it sits on top, around the surface area where the oil has soaked in, giving the shiny-flat-shiny-flat look.

In the sunlight, the shiny-flat-shiny-flat look is not pretty. However, this effect is only temporary and after 3-9 months the oil eventually soaks in behind the stain and the stain will delaminate further.

After 3-9 months, we will come back and give the boards another heavy wash, sand back any remaining stain and apply another coat of oil. 9-12 months later we repeat the same process. After 12-24 months the process will be complete and the Cedar will move into a regular maintenance schedule, with sun exposed areas being treated every 2-3 summers.

What Costs Are Involved?

Cost is the final hurdle for many Cedar homeowners. Stripping off stain is an expensive process and if your current home is not your forever home, the costs might be prohibitive.

However, if you are planning to stay in your current home for the foreseeable future, the costs become an investment that will pay for itself. Over time, oil is much easier to apply than stain, provides superior protection against the elements and increases the lifespan of your Cedar.

In broad terms, it comes down to this: do you want to spend the extra 10k to remove the stain and give yourself an easy to maintain finish, or deduct the 10k from the cost of replacing the cladding in the not-to-distant future?

By investing in the health of your Cedar now, you will save money on long-term maintenance, and your cladding will look amazing.

In this article, we are looking at how to protect the value of your Cedar home - often your biggest asset - especially when the market is so volatile and uncertain.

The benefits of Cedar maintenance fall into two main categories: beautification and protection.

Beautification means making your Cedar look beautiful all year round. If sun exposed areas are left without replenishing the oils, the Cedar can start to look worn and tired. By adding oil back into Cedar, you are protecting it from the harsh New Zealand sun and restoring the natural vibrance of the timber. 

Protection means maintaining the integrity of the timber, so you don’t have to replace the Cedar in the future. Protection can also mean protecting your investment, both to maintain the value of what you just bought, or to improve the asking price if you are about to sell. 

In this article, we are looking at how to protect the value of your Cedar home – often your biggest asset – especially when the market is so volatile and uncertain. 

For some additional insight into the housing market, we are joined by Rachel Readhead from Barfoot & Thompson. 

Why Protect Your Cedar

People often think that if their Cedar looks tired, it needs to be maintained or restored, but that is not necessarily true. Cedar is a very resilient timber.

If not maintained in the short term, sun exposed areas will get damaged by the harsh UV rays and end up looking rather shabby. Not ideal, but not the end of the world either. 

If not maintained in the long term – we are talking 20+ years here – the Cedar may cup or warp, no longer protecting the outside of the house. The ultimate cost will be to replace the Cedar cladding on sun exposed faces, which is considerably more expensive than regular maintenance. 

“If the Cedar has started to warp or crack, it will raise red flags when the property report gets done. When doing a CMA [comparative market analysis] on the property, everything is taken into account,” said Rachel.

Return on Investment

When considering the cost of Cedar maintenance or restoration, there are two questions you need to consider.

  1. What do I have to spend so that I never have to replace my Cedar?
  2. Do I also want the Cedar to look beautiful all year round?

The average restoration price for a 3-bedroom home is $6.5k. After the initial restoration, sun exposed areas need recoating every 2-3 summers. The cost of regular maintenance comes down to around $2.5-5k, depending on the house size and build. 

If your Cedar is already in good condition and you want to maintain the value over the long term, you will need to recoat sun exposed areas every 2-3 summers. 

If your Cedar hasn’t been maintained in some time and you want to restore the timber before you sell the house, you will be looking at anywhere between $6.5-15k.

On houses we have worked on in the past, the valuations were around 6 times higher after we did the work. So, for an investment of $4.5k (the average price of a restoration in the past) the valuation was $24k higher.

Thinking of Selling?

If you are planning on selling your home soon, you can potentially increase the selling price by sprucing up the cladding.

At a minimum, you can stay firm on your asking price and stop people knocking you down on price due to additional work. 

“First impressions count, and the condition of the cladding is usually the first thing people see when looking at a property. A lot of buyers will ask for a price reduction if there is work to be done on the exterior of a house,” said Rachel. 

If you have been maintaining the Cedar regularly, you may not need to do any maintenance at all, or just some light maintenance to tidy up the sun exposed faces.

Stand Out in a Crowded Market

When the housing market slows down, buyers have more houses to choose from and have more room for negotiation.

Rachel says, “Houses are not moving as fast as in previous years, especially in the townhouse and apartment market. A good house in a good location always sells, but by keeping your house maintained you can stand out from other properties and get a better sale price – especially if it sells in auction.” 

Having a record of maintenance also gives prospective buyers confidence that the timber has been looked after and won’t require work anytime soon.  

Rachel added, “Many people still do not understand how affordable it is to look after a Cedar home and mistake it for painting, which can often be more expensive. Having documentation of previous work shows prospective buyers the cost of maintenance over the long term and helps to ease any concerns.” 

Protect Your Biggest Asset

By investing in the maintenance of your Cedar, you are investing in the long-term value of your home.

And by regularly maintaining your home, you are spreading this cost out over many years, instead of getting lumped with a large bill when it comes time to sell. Regular maintenance also has the benefit of being able to enjoy the natural beauty of the Cedar while you are still living there! 

Protecting your investment starts with a conversation. Our team can help to identify what your goals are, then put together a plan to protect your Cedar over the long term.

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.

Let's get to the point. Is DIY Cedar maintenance possible? Absolutely. Furthermore, the process is relatively straightforward. But there are some factors to consider before attempting DIY.

Let’s get to the point. Is DIY Cedar maintenance possible?

Absolutely. Furthermore, the process is relatively straightforward.

Cedar maintenance is all about protecting the timber from the elements, most importantly, the harsh New Zealand sun. If you have a long, hot summer, the natural oils in the boards will be sucked out by the sun.

Your job is to replace the oil that the sun is extracting. Without oil replenishment, the boards will dry out over time and begin cupping.

A general DIY Cedar maintenance plan would involve soft washing your house once every few years and applying a coat of oil to sun-exposed faces every 2-3 summers.

Seems straightforward, right?

So is changing the oil on your car, but very few people have the time or are willing to get their hands dirty. The same goes for Cedar.

Here are some factors to consider before attempting DIY maintenance.

1. Convenience

We have a customer in Northland who is 83 years old and had previously maintained the Cedar on his family home for decades – and did a great job of it. Now that he can’t get up the ladder like he used to, he came to us for help.

Anybody can learn how to maintain their own Cedar, but not everybody has the inclination. Maintaining Cedar is physically demanding, often working at heights, using bulky equipment, in a wet and mucky environment.

Hiring a professional means you don’t have to worry about anything. They will bring all their own equipment, have experience working at heights and clean up after themselves, leaving nothing but a beautifully maintained house.

2. Property Access

Accessing the different areas of your house can be tricky, and potentially dangerous.

Even on a flat property, there are always parts of a house that are difficult to reach. The job gets even more complicated if the ground is uneven.

Double story house can be quite daunting. Some houses require scaffolding, but most houses can be accessed with a ladder.

If you are not comfortable working on a ladder, or the ground around your house is uneven, it is usually safer to hire a professional who is experienced working at heights.

If your house does require scaffolding, a professional Cedar maintenance company will often have their own scaffolding and manage the whole process, saving you time, headaches and money.

3. Risk of Damaging the Cedar

The surface of a Cedar weatherboard can be easily damaged. The water blaster should be set at a low pressure and moved across the boards in a steady motion without pausing.

Water blasting at a high pressure can strip away too much of the soft tissue in the timber, leaving it streaky and unsightly.

This is often when we get called, only now the customer is paying for remedial work to restore the damage rather than just maintenance.

Your home is usually your most valuable investment. By hiring a professional, you are removing the risk of damaging the timber and ultimately, adding value to your investment.

4. Preparing the Cedar for application

Cleaning and preparing the Cedar is the most important part of getting a satisfactory finish.

People can be so scared of damaging the timber, that they use a water pressure that is too low or don’t scrub sufficiently to properly clean the Cedar.

If you do not remove all the built-up organic matter, whatever you put on the surface will then be compromised.

To prepare your Cedar with a water blaster, make sure you wash it at the right pressure, or scrub the boards with an appropriate brush, making sure the boards are free of any timber fibres, oxidised tint, dirt, mould, lichen and moss.

Once all that is gone, you need to make sure any stain on the boards is evenly removed. You don’t want the boards under the soffit left a different colour.

5. Consistent application of the product

Applying a stain is simple, you move the brush from one side to the other keeping an even coverage and a wet edge.

But getting an even finish across the boards takes time and practice. If the stain dries before you finish, there will be lines in it.

We have also seen DIY oiling attempts that only go 3/4 of the way up the wall because they couldn’t reach any higher, or thought the Cedar was protected by the soffits of the house.

Trying to blend that in after the event is very difficult and always ends up costing more in the long run.

Thinking Twice About DIY?

Anyone can learn how to maintain their Cedar, but it probably looks easier than it is and is fraught with little problems that when added together, become bigger issues.
