Strong, long-lasting and pleasing to the eye, macrocarpa has been a a favourite building material in our neck of the woods ever since the early 20th century. A growing trend in landscaping, it adds an elegance and rich organic feel to everything from retaining walls, decking, steps and raised planter beds, to outdoor furniture like bench seats and tables, and even pergolas. Macrocarpa is a medium-sized coniferous evergreen native to the Central Coast of California, where it is commonly known as Monterey Cypress.

When freshly cut, the wood excudes an alluring spicy aroma, while its bright-green leaves release a zesty lemon-like fragrance.

It first arrived in New Zealand in the s, where its hardiness made it popular for use as a windbreak tree on farms, typically grown in shelter belts or rows. For the same reason, it has been used here for railway sleepers, and been in high demand as a construction material ever since the early s.

A number of macrocarpa varieties are grown in our country, including ones that can withstand poor soil qualities, but the main plantation cypress cultivated here and especially in the North Island is Lusitanica because of its natural resistance to the canker fungus. Another pure plus is the Kiwi climate — which appears to be more favourable to its growth than in its native California.

Spoilt with warm summers and mild winters, as well as the absence of many disease-causing microorganisms, the trees here naturally tend to grow to a much larger size, some of them shooting up to 40 metres and sporting 3 metre-wide trunks.

This, and the fact that the timber is naturally resistant to rot and insect attack without having to chemically treat it, makes macrocarpa one of the most eco-friendly and safest timbers produced in Aotearoa. This is especially important when adding outdoor features that involve edibles — think compost bins, garden beds and veggie planter boxes. Another eco-friendly spin-off is that macrocarpa will fade to a silvery grey when left untreated or stained — a look that tends to blend in well with any home design or natural garden surroundings.

When used outdoors, it is recommended that you choose macrocarpa heartwood the inner bit — the sapwood the living, outer partneeds to be treated to keep insects at bay treatment and cannot be treated for decay.

This info is based on years of experience working with cypress timbers. Naturally, under the building code, our Heart Mac is durable to H3.

The logs them selves have very little sapwood in them. In mac the sapwood ring is very small and this means that most of the log can be used for heartwood applications.

Mac Sapwood is also resistant to borer in a natural state and is widely used in areas where this is a serious problem. While this occurs in the natural drying process, we want to prevent it opening up too much. Oiling the timber is like conditioning or moisturising your face in the morning. It also protects and repels water. Painting our timber is perfectly ok, but beware of dark colours.

Also part of this protection of the timber you can choose from a wide variety of colours and tints. We stock the following products and are able to pre-oil these products to save you time. Checking and shake are terms used to describe the natural cracking that occurs in the timber. Checks occur due to the top layers of the timber drying to rapidly.

A MacDirect we take care to ensure we dry our timber over a minimum of 4 weeks, both air drying out of direct sunlight and kiln drying. See the oil section to see how to best protect from checking.

So it's important to allow your timber to acclimatise in the space that it will be installed. Otherwise you could see additional shrinkage of up to 2mm. Timber will absorb moisture as well so always acclimatise it.

Natural timber is a lot of nuances.Ventilation around the decking timber is important to allow for adequate air flow and will help extend the life and performance of the deck. The deck should have at least mm clearance from the ground. This, in conjunction with suitable spacing, will allow for suitable ventilation.

In wet areas or over water, additional clearance is recommended. An additional face coat following installation is also recommended. Note: When coating decking timber, ensure that the boards are free from surface marks and stains before coating. End sealing will help minimize splitting and surface checking on the ends of the boards. We strongly recommend use of stainless steel screws for fixing your decking to the deck frame.

We recommend 75mm long stainless- steel screws through the pre-drilled face of a 35mm thick decking board, two screws per joist. Macrocarpa decks should be cleaned with a stiff brush at least once a year to clear gaps and remove surface mould which can be a slip hazard in wet weather. Keeping the deck clear of leaf litter, moving pot plants or other large objects that may hold moisture to the top of the deck, is also important for the life of the deck. Softwood Decking can be water blasted BUT it is important to do so at a low pressure so as not to damage the fibres of the board by going too hard or too close.

Care must be taken not to stop at the end of the stroke but to lift the nozzle away when changing direction. Removing dirt and mould prior to coating is easy with OneStopDeckShop Deck Cleana simple 4 step system that ensures your deck is ready for coating. One Stop Deck Shop Deck Clean active restoration agent is the recommended product for general cleaning.

Installation Ventilation around the decking timber is important to allow for adequate air flow and will help extend the life and performance of the deck.

Spacing: 35mm decking boards should be installed at a maximum mm joist centres. Joists should be clean and sound and the screws should penetrate at least 40mm into the joists to achieve good holding. Pre-drilling and counter-sinking is essential to avoid end splits.

This is to allow for some minor shrinkage as the boards acclimatise, which will allow for drainage of surface water and air circulation. NB: These are recommendations only. An allowance for regional climatic conditions should also be factored in. Fixings: We strongly recommend use of stainless steel screws for fixing your decking to the deck frame.With more than 25 years experience, we have built a reputation of knowledge and quality. Here's where you will find a few of those answers. If this page doesn't satisfy, we are always on the end of the phone ready for the next challenge.

Although some plantations were planted in early Lusitanica Mexican Cypress came in at a later date. Macrocarpa has been used in house building around NZ since the early s. St Peters' gates in Vatican City were built with 'old world' cypress and are still there today, years later. Foresters have always recognised the heritage of cypress as a premium timber and many discerning home builders have used Macrocarpa for the last years in NZ. While Lusitanica is lighter in colour than Macrocarpa when first processed, in a short while it is hard to distinguish between the two.

Lusitanica because of its higher resistance to bush canker and better sawmilling qualities is the main plantation grown cypress, particularly in the North Island. New Zealand grown Lawson does have quite a large sap ring compared to Macrocarpa.

Tight Knot 1 - This is used for all building applications. May include sapwood. Due to the low amount of sapwood in Mac, this is also suitable for external applications. Not code compliant for external applications. This timber meets code compliance for internal applications. Includes some bark encased knots and some feature knots. Clears - This is our furniture and finishing grade timber.

We also can grade clears for Heart for external use. Clears means no Knots. Please enquire. Not always available. Where Macrocarpa has been recorded as lasting many years even in in-ground situations. It must be recognized that like all naturally durable timbers there is large variability in durability. Larger sections such as fence posts will last longer. MacDirect sells considerable amounts of decking from heart grade.It can be used outside for weatherboard, surfeit, facia, pergolas, decking and outdoor furniture.

It is not recommended in-ground for construction purposes including in-ground posts for fencing, decking and pergolas. Macrocarpa supplied in New Zealand is grown within New Zealand as an exotic tree. Supplies of good-quality timber are increasing, either milled to specific requirements, or available from specialist suppliers as finished products for example, mouldings and flooring profiles. In the early s, it was estimated that there were about ha of pure macrocarpa plantations in State forests, in mixtures and another ha in private plantations.

Well-managed plantations of cypress have since been established. Cypress timbers currently make up the third most commonly used exotic timber species in New Zealand, with approximately 20, m3 cut per year. Therefore, for small landowners, the species represents a viable economic alternative to radiata pine for woodlots.

The increase in market demand for cypresses offers farmers both a low-cost way to reduce negative impacts of farming on the environment, and a lower-impact land-use option than radiata pine. Supply of timber milled to larger sizes is limited in certain parts of the country, and sizes larger than x 50 mm can be difficult to source. Strength: Macrocarpa is a low-to medium-density softwood that looks and works like kauri.

Durability: Both the heartwood and sapwood of macrocarpa are naturally borer resistant Anobium for interior housing purposes. The heartwood is moderately durable for above-ground purposes, but the sapwood is non-durable. The timber cannot be pressure treated with copper, chromium and arsenic CCAbut sapwood can be boron diffusion treated to resist insects but not decay. Finishes: Macrocarpa, when dry, will accept a variety of paints, oils, two pot resins and varnishes.

Working properties: Macrocarpa has a fine grain and machines and sands well to give a high-quality finish. Appearance: The heartwood is golden brown and has a speckled lustre, which is rare in timber.

Macrocarpa Decking

Freshly cut timber has a fragrant spicy odour, which is typical of cypresses. It is a very stable wood, is easily sawn and has relatively low surface hardness, with good working and finishing characteristics and relatively uniform wood properties. Macrocarpa heartwood is naturally durable for above-ground purposes, but sapwood requires treatment.

For this reason, if macrocarpa is to be used for outdoor purposes, heartwood should be specified and supplied. Above ground, the heartwood timber should be sound for 20 to 30 years, and if exposed to the weather, but protected from direct sun and rain, will last 40 to 60 years. Both the heartwood and sapwood of macrocarpa are naturally borer resistant Anobium when used for interior housing purposes.

These will not be the same strength properties as structural lengths of timber. For the properties of structural length timber please see the tables under the structural design section. For 12 percent moisture content defect-free timber, of average density, from trees felled at 30 years of age, the average properties measured on small specimens 20 x 20 mm cross section are:.

Modulus of elasticity 5. The timber is relatively soft, but has fairly uniform density from pith to outer rings. It is difficult to dry and prone to collapse and checking. Timber for interior use should be air dried to 30 percent moisture content before kiln drying to final moisture content, timber for exterior use should be air dried to the final moisture content.

Turning Turns well at higher speeds, similar tear out on end grain to radiata pine.Last Sunday I threw an outdoor table and bench seats together, but dont really know what sort of finish to put on it.

I scored all the timber from the guy down the road with a portable mill so have just finished sanding all the milling marks out.

Eco Wood Treatment & Stain

What can you put on to keep the golden glow that doesn't need reapplication too often? I have a bottle of linseed oil, will that work or do I need something better?

Please Log in or Create an account to join the conversation. Gidday I suggest you go into Mitre 10 or similar and ask as there are lotsa stuff onm the market these days that weren't around whenI was doing most. But I would be surprised if you can get anything that stops the discolouration totally. Macrocarpa is quite hard to keep looking nice, no matter what you put on it, because it tends to go silver in sunlight. My joiner Uncle only uses Sikkens oil on macrocarpa, which comes in clear or tinted, but it is the most expensive option.

He recommends his clients reapply every year. PG, can you ask him what oil I should be putting on rimu. I have sanded down my bedroom window before the op [ ] and it is now ready to be oiled. Decided it would be better oiled than varnished re future maintenance. It is in sunlight most of the day. I dont really have a problem oiling once a year as I'm not really a fan of the silver look. Will go into bunnings and mitre 10 over the weekend. My next problem is getting it round the back to the patio area.

It is 3mx1mxmm and really heavy, I might have to talk to the neighbour nicely and use his little 1. Here's the table before I sanded it. So far it hasn't cost me a cent, just some roofing iron when I next do a re-roof. Attached files.

Gidday Hey Spook, the very best thing for ewe to ewes is a stuff from Resene's I think it's call timber lock or something. Ewe ewes it before applying oil just to get it back to it's original brilliant colours, then apply the oil. Benjamin Moore used to do a oil treatment product for cedar sidings that contained a fungicide and was aimed at keeping the timber colourings as new. Maybe worth checking out?

Guy from the Slab place in Masterton told me to get the cheapest oil I could find and apply several coats over several weeks until when I put a cigarette paper on top it absorbed oil.

Basically oil until it can't take no more. Well, I have moved it to the patio area thanks to my kind neighbour and his little hi-ab. And have decided to oil it with outdoor decking and furniture oil but what brand to use. What is everybody elses experiences and reccomendations with these brands? I hate resene paint By the way the formula for oiling something is once a day for a week, once a week for a month, once a month for a year and then 3 or 4 times a year as needed.

I've only used the polyurethene What about boiled linseed oil?
