Frequently Asked Questions

Feel free to find our answers below.

  • What is Wood-X?

    Wood-X is an umbrella brand for a range of wood care products. The core products are wood oils i.e. Wood-X Cedar Oil and Wood-X Deck Oil. These are non film forming, viscous MINERAL oils designed to penetrate into absorbent, chemical preservative free exterior timber products such as Western Red Cedar weatherboards, fascia’s, boards, beams and mouldings.

    Wood-X wood oil coatings will improve the dimensional stability of naturally durable exterior hardwood timbers, including decking. Wood oil migration into dense, less absorbent hardwoods will be shallower and progression slower by comparison to lower density, more absorbent timbers.

    Typical uses

    • Timber weatherboard
    • Wall Shingles
    • Roof Shingles*
    • Structural Posts and Beams
    • Hardwood and Cedar Decking
    • Outdoor timber furniture**
    • Fascia
    • Mouldings
    • Timber Garage Doors
    • Boards
    • Fences
    • Pergolas

    * Drinking water should not be collected from Wood-X coated surfaces

    ** Allow the oil to thoroughly penetrate the timber surface before use

  • What are its properties and specification?

    Wood-X penetrating wood oils are Mineral Oil based, with added Biocides and Pigments (The ‘Clear Base’ product does not have Pigments). They provide anti-fungal and water repellent qualities to reduce the speed of moisture uptake and loss in exposed exterior timbers, thereby limiting the potential for warp, twist, cupping, splitting and surface checking.

    Vehicle type Mineral oil
    Pigmentation Natural coloured oxides and selected durable pigments
    Other Biocide package
    Finish Progressive migrating type
    Colour Natural or ‘Clear Base’(no UV protection) and a selection of standard colours from the Wood-X colour range. Custom colours available on request.
  • Is it toxic / safe to use?

    Although the toxicity of Wood-X wood oils is very low compared to alternative coatings in the market, we can not anticipate the health status of a potential user. Here therefore are the key health advisory’s for Wood-X wood oils. Please be aware that the wording on the labels of any pail of paint, stain or wood oil are very similar in message i.e. there are chemicals in this product, some of which may be injurious to your health so be careful with its’ use.

    With respect to Wood-X wood oils ….

    1. Contains powerful fungicides. Avoid skin contact. If any skin contact occurs, wash skin immediately and thoroughly with soap and water. Do not scrub the skin.
    2. Wear protective full body over wear and elbow length, PVC gloves during handling and application.
    3. Protect eyes from contact with the oil. Use safety glasses with side shields as a minimum precaution. If eye contact occurs, thoroughly wash with fresh, cold water for at least fifteen minutes and seek immediate medical attention if required.
    4. Keep away from heat and open flame. Keep containers closed when not in use.
    5. Avoid breathing vapour. Use with adequate ventilation.

  • How much stain do I need per m2?

    Coverage of Wood-X penetrating wood oils are dependent on surface condition, timber type, air temperature and other factors. The following is an approximate, typical guide.

    Dressed timber(Fresh) Band Sawn and Diamond Cut timber (Fresh) Rough Sawn and Badly weathered timber
    First Coat 9 – 14 sq mtrs per litre 5 – 8 sq mtrs per litre 3 – 5 sq mtrs per litre
    First Re-Coat 12 – 15 sq mtrs per litre 8 – 10 sq mtrs per litre 5 – 8 sq mtrs per litre
  • How is it applied? By brush, rag, roller, spray or other?

    Apply by brush, roller or spray. Saturate the surface of absorbent timbers with Wood-X migrating wood oil at the typical coverage rates for the various substrates listed above. Apply more sparingly to dense timbers e.g. hardwood.

    During application, stir or shake the contents of the container frequently to ensure even distribution of colour through the clear base.

    Wood-X will penetrate or diffuse into the timber surface most readily when the coating is warm, the timber surface and atmospheric conditions are warm and dry. Conversely, application and penetration will be slowest during damp, cold climate conditions. For best practice, store Wood-X containers in warm surroundings prior to use and apply in a warm, dry space.

    Spray: Use airless, low pressure spray with a coarse spray tip.

    Brush: For speed and efficiency use a wide, quality bristle brush for rough surfaces

    Roller: Use a long nap or suitable sponge roller for Band sawn or Rough surfaces

  • How do I clean up brushes etc?

    Clean up: Clean up with mineral turpentine and/or hot water and detergent. Use a clean, dry absorbent cloth to wipe initial excess or to complete the cleaning process.

  • Do I need to coat the unseen back of boards?

    Yes. The need to control natural moisture flow in and out of the timber is equally important for the back or unseen face as it is for the board ends, edges and visible, outer face.

  • How soon is it touch dry?

    As Wood-X Wood Oils are mineral oil based, they do not dry. However, as the coating soaks into the timber it will appear or feel at the touch to be ‘dry’ on the surface.

    Dry to touch (minimum) 24-48 hours on Band sawn face WR Cedar. Extended periods on Dressed surfaces and hardwoods, particularly during unfavourable drying conditions
  • How soon is it okay to walk on when applied to hardwood decking?

    When the initial, excess surface oil has ceased to sit proud on top of the timbers surface i.e. when the coating has penetrated beneath the timber surface. This could take some days or even weeks in cold weather and/or if the hardwood is particularly dense. The Oil will penetrate with time as the product works to open up the timber surface. If tardy migration is being experienced, we recommend any excess Wood Oil be wiped off with an absorbent, lint free, clean and dry cloth. Subsequent applications will tend to penetrate more readily on the back of a well penetrated initial coat.

    Dry to touch(minimum) 24-48 hours on Band sawn face WR Cedar. Extended periods on Dressed surfaces and hardwoods, particularly during unfavourable drying conditions
  • Will it help retain the original timber colour?

    In exterior applications subject to the impact of moisture and UV light, the answer is No. The natural base colour and porosity of any timber will affect the appearance of the Wood-X Colour Toned coating. It will typically appear darker on both darker and/or more absorbent timbers and lighter on lighter toned and/or less absorbent timbers. With timber species that generally include a distinct range of colours within and between individual pieces (e.g. Western Red Cedar) it is advisable test coat a selection of these base timber colours for the best appreciation of the likely overall appearance of your finished project.

    ‘Clear Base’ imparts no obvious colouring to the timber surface other than to initially darken darker timbers and initially brighten or lighten, lighter coloured timbers.

  • Will it stop the timber from warping and moving?

    No, not in all boards and not entirely. The product will contribute greatly to overall board stability by slowing moisture absorption and loss but it will not stop the natural, extreme instability character of some boards and in particular, some naturally unstable timber species.

  • How do I clean and maintain coated timber?

    It will depend on a number of factors. Your best reference is the current Wood-X Technical Data Sheet.

  • Can I add a tint to clear base after initial coat, or change original tint, going darker etc. if don’t like selected tint?

    Yes to both questions. Additional Wood-X tint pots can be purchased.

  • Why do you recommend Wood-X wood oils over other products on market?

    Every exterior coating product has its’ own unique features. We prefer Wood-X for a number of reasons. Amongst these are its’ excellent Biocide package, high quality and proven Tints (colour tones), High grade oil content that speeds its penetration and therefore ‘dry to touch’ time (Wood oils actually never truly dry!). We also prefer the wide (and expanding) range of colours available.

  • Ongoing maintenance: How soon before I should have to recoat Clear Base Wood-X wood oil?

    Wood-X ‘Clear Base’, unlike the Colour Toned option, imparts no obvious colour to the timber surface other than to initially darken darker timbers and lighten or brighten lighter coloured timbers. The need for re-coat or maintenance will then come down to the individual clients preference for continuance or otherwise of the products water shedding and anti-fungal properties.

  • Ongoing maintenance: How soon before I should have to recoat Colour Tinted (Toned) Wood-X wood oil?

    It will depend on your application.

    Wood-X penetrating wood oils should be maintained or re-coated when their properties have deteriorated. Colour fade and loss of ability to ‘bead’ water are good indicators. Both factors will be heavily dependent upon degree of surface exposure to direct weathering, timber finish, timber type, Wood-X colour and amount of Wood-X wood oil originally applied to the timber. In simple terms, when colour or water repellent properties have been reduced, then maintenance should be carried out.

    In instances where previously Wood-X coated timber has deteriorated to a point where restoration of the coating and timber surface is required, please refer to the ‘Wood-X coated timber overdue for a re-coat’ section of the current Wood-X Technical Data Sheet.

    Guide Re-Coat Periods For Wood-X Colour Toned on Western Red Cedar Weatherboards
    Weatherboard First Re-Coat Second Re-Coat(after 1st re-coat)
    Horizontal Dressed Face Boards 8 – 24 weeks 12 – 24 months
    Horizontal Dressed Face Boards (Sanded) 8 – 16 weeks 12 – 24 months
    Horizontal Band Sawn Face Boards 6 – 12 weeks 12 – 24 months
    Vertical Dressed Face Boards 16 – 24 weeks 12 – 24 months
    Vertical Dressed Face Boards (Sanded) 12 – 24 weeks 12 – 24 months
    Vertical Band Sawn Face Boards 12 – 24 weeks 12 – 24 months
  • What are the differences between Wood-X Wood Oils and other brands of wood oil?

    Wood-X differs due to its’ wider colour range, more highly refined grade of oil and proven anti-fungal package. The more highly refined oil content speeds penetration and therefore the ‘dry to touch’ time (Wood oils actually never truly dry!). Wood-X also has its’ own wide (and expanding) range of contemporary colours available. ( Wood-X colour chart )

  • Can I coat over another brand of wood oil or vice versa?

    Quite possibly but we can not offer any surety of performance if an alternative Wood Oil styled coating or any other style of coating for that matter is applied before or after a coating of Wood-X. This is because every exterior coating products has its’ own features or points of difference, some of which may be trade secrets. If this is the path you wish to proceed along, your decision must be at users risk. Our best advice in this case would be after cleaning, to trial test a small inconspicuous area of the intended application area and assess performance over a period, until you are satisfied to proceed or otherwise. Please remember that we prefer Wood-X for a number of reasons. Amongst these are its’ excellent Biocide package, high quality and proven Tints (colour tones), High grade oil content that speeds its penetration and therefore ‘dry to touch’ time (Wood oils actually never truly dry!). We also prefer the wide (and expanding) range of colours available.

  • Can I apply a traditional Exterior Oil Stain such as Resene Waterborne or Solvent based Woodsman over timber previously coated with Wood-X.

    The short answer is ‘Possibly but likely not without difficulty and only with a long passage of time since the last application of Wood-X’. The preceding Wood-X coating would need to have deeply penetrated (this takes some time), any residual professionally removed and the surface cleaned before application of any Oil Stain could be considered. In such cases we recommend trial coating small test areas first before any decisions are made with respect to widening the job scope. Guidance should be sought from the Stain manufacturer.

  • Can I apply Wood-X over a pre-existing oil stain e.g. Resene WB Woodsman?

    Yes, but only with effort. The preceding coating would need to be professionally removed from the timber surface before Wood-X application could be considered. In such cases we recommend trial coating small test areas first before any decisions are made with respect to widening the job scope.

  • What preparation is needed for re-oiling?

    Refer the current Wood-X Technical Data Sheet. There are a number of factors to consider, all of which are covered in the TDS.

  • When should I re-oil?

    Wood-X penetrating wood oils should be maintained or re-coated when their properties have deteriorated. Colour fade and loss of ability to ‘bead’ water are good indicators. Both factors will be heavily dependent upon degree of surface exposure to direct weathering, timber finish, timber type, Wood-X colour and amount of Wood-X wood oil originally applied to the timber. In simple terms, when colour or water repellent properties have been reduced, then maintenance should be carried out.

  • Is Wood-X environmentally friendly?

    Wood-X is not classified as a …

    Poison

    Toxic substance

    Corrosive agent

    Flammable substance or

    Eco-Toxin

    Wood-X has very low levels of Volatile Organic Compounds (VOC’s). These compounds have potential to damage the environment when they evaporate off a liquid Oil, Stain or Paint when it is being applied.

    Precautions

    • Contains powerful fungicides. Avoid skin contact. If any skin contact occurs, wash skin immediately and thoroughly with soap and water. Do not scrub the skin.
    • Wear protective full body over wear and elbow length, PVC gloves during handling and application.
    • Protect eyes from contact with the oil. Use safety glasses with side shields as a minimum precaution. If eye contact occurs, thoroughly wash with fresh, cold water for at least fifteen minutes and seek immediate medical attention if required.
    • Avoid breathing vapour. Use with adequate ventilation.
    • Drinking water should not be collected from Wood-X coated surfaces e.g. Shingles
    • In areas where rain water may pass over freshly coated Wood-X surfaces before entering guttering, disconnect adjoining rainwater down pipes from waterway access and direct out on to bare ground for at least two heavy rain periods.
    • In areas where rain water may pass over freshly coated Wood-X surfaces, excess oil residue may initially run off onto adjacent surfaces. This will cease as the coating migrates into the timber and pigment binds to the surface. Take care to check compatibility with Wood-X oils of adjacent surfaces prior to coating and ensure run off if any, does not mark or contaminate surrounding areas and/or materials.
    • Do not contaminate waterways by cleaning of equipment or disposal of wastes.
    • Avoid contact with plants and animals.
  • Does Wood-X contain VOC's

    Yes, at 67g/L total. Wood-X therefore has very low levels of Volatile Organic Compounds (VOC’s). These compounds have potential to damage the environment when they evaporate off a liquid Oil, Stain or Paint when it is being applied.

    The VOC’s present in Wood-X are …

    Toluene – 2 g/L

    Methyl Carbitol – 3.7g/L

    White Spirits – 61.4 g/L

  • Can I apply Wood-X to walls above rain catching roofs?

    Yes, you can but down pipes should be disconnected and left to flow safely out on to the ground for at least two periods of heavy rainfall being allowed to directly impact and/or wash down on to and over the coated boards. The general guidelines are …

    • Drinking water should not be collected from Wood-X coated surfaces
    • In areas where rain water may pass over freshly coated Wood-X surfaces before entering guttering, disconnect adjoining rainwater down pipes from waterway access and direct out on to bare ground for at least two periods of direct impact (direct and full wash down) heavy rain periods.
    • In areas where rain water may pass over freshly coated Wood-X surfaces, excess oil residue may initially run off onto adjacent surfaces. This will cease as the coating migrates into the timber and pigment binds to the surface. Take care to check compatibility with Wood-X oils of adjacent surfaces prior to coating and ensure run off if any, does not mark or contaminate surrounding areas and/or materials.
    • Do not contaminate waterways by cleaning of equipment or disposal of wastes.
  • Does Wood-X have an expiry date after purchase?

    No. On every occasion after allowing to settle and before use, the product must be shaken and stirred vigorously and thoroughly to bring all constituents back into uniform suspension.

  • Is there an issue with dark tinted Wood-X formula’s?

    Dark toned colours will have reduced longevity as they naturally attract accelerated UV degradation and heat. Periods of excess and prolonged exposure to heat may unduly stress the timber substrate and lead to the expression of seasoning characteristics, particularly when the coating is overdue for a maintenance coat e.g. surface checking, cupping, twist etc.

  • What is the difference between Wood-X and an Oil Stain?
    • Wood-X is a Wood Oil, not an Oil Stain.
    • A traditional oil stain only penetrates a small distance below the timber surface. Wood-X however penetrates much further.
    • A stain will lose its water resistance when it erodes away from the surface. Wood-X, by virtue of its’ superior volume of oil content and natural migrating properties, will penetrate below the surface and provide water resistance for a comparably longer period.
    • A stain has active driers in its composition i.e. technically an Oil Stain will dry. However Wood-X wood oils will never truly dry.
    • Wood-X offers higher dimensional stability properties to timber to that of a stain, by virtue of greater moisture control over a longer period and by taking the place of ‘lost moisture’ in the surface cell structure.
    • Most oil stains are made of modified natural oils (vegetable etc.) where as Wood-X is a Mineral oil
  • Will it stain my clothes if I brush up against a wall?

    Potentially so. Abrading or rubbing up against the surface should be avoided, particularly in the early weeks after application and when the oil coating has aged and maintenance is overdue. Band sawn timber surfaces are recommended over Dressed or Smooth timber surfaces for several reasons, including their ability to hold the surface pigments with more resilience.

  • If so, how long until it won't?

    Wood-X wood oils are made up of mineral oil, biocides, a small amount of solvent and a very small amount of resin. The resin is there to help the Wood-X colour tint pigments bind to the outer surface of the timber, while the oil penetrates into the timber. If the oil does not fully penetrate into the timber, it will not allow the resin holding the colour pigments to set. That is, these colour pigments are left vulnerable to pick up from clothing or any absorbent or scouring material that brushes up against the oil and pigment combination

    Once the oil penetrates into the timbers’ subsurface, the resin and pigments are then exposed to naturally present oxygen. Exposure to oxygen dries the resin through an oxidation process, helping to bind the colour pigments to the surface timber fibres.

    Over time, as the UV from the sun breaks down both the resin and the outer wood fibres (surface wood fibres) the slow process of coating erosion occurs. These loose, eroding fibres and or pigments can also come off on clothing, more so in a dry state (late in the weathering cycle) as opposed to wet oil (early and mid cycle).

    The main issue we come across is when some one puts too much oil onto a surface, either by over vigorous application or by prematurely over coating a previously coated Wood-X surface. In both cases the wood oil can not penetrate the timber surface, leaving coating (oil and colour pigments) vulnerable to premature failure through ‘Wash down’ and surface abrasion (anything that brushes up against the surface).

  • I live close to the Sea, is Wood-X ok for that environment?

    Yes, but you may find that periods between re-coats are lessened due to the physical impact of blown sand, sea salt and water (abrasion). Exposure to UV, reflected heat and light will be greater and therefore have a more detrimental influence on any coating in this environment i.e. reduced life span of any coating.

  • Why do you need to coat all 6 sides?

    For moisture control i.e. for timber stability and coating performance. The need to control natural moisture flow in and out of the timber is equally important for the back or unseen face as it is for the board ends and visible, outer face.

  • Can I get some samples of the colour on a piece of Cedar?

    Of course. Have you selected or do you have in mind a Cedar product for your end use? etc.

  • Can I buy the Wood-X from a merchant or Paint supplier?

    Yes. Call 0800 WOODOIL ( 9663645 )

  • Can I use a Wood-X colour based stain?

    Yes, subject to your application. We do not recommend colours for timber decking or areas exposed to the potential for impact or abrasive wear.

  • Can I use a Wood-X colour based stain on my hardwood deck?

    No. Only ‘Clear Base’ and sparingly applied in this situation.

  • Why should I be favouring Wood X ‘Clear base’ Deck Oil to coat my hardwood decking over alternative decking oils and stains?

    It depends on what you wish to achieve. We promote Wood-X ‘Clear Base’ as a timber stabiliser and mould inhibitor over the period it takes the deck to weather naturally to a silvery grey. If your preference is to ‘Colour’ their deck we do not recommend Wood-X. However, you should be aware that in our experience, applying a colour toned coating to hardwood decking will require regular maintenance and will be susceptible to wear in areas of highest foot traffic. Our observation is that many people will shy away from coloured coatings once they are aware of the maintenance and wear issues of alternate deck coating options.

  • What are the advantages of Oiling our deck with Wood X Clear oil than not oiling our deck at all? Is it a necessity?

    No, it is not a necessity. It’s a strong recommendation for enhancing timber stability and inhibiting the expression of seasoning characteristic’s in the timber. In applying the oil sparingly to all six sides of the decking you will be slowing the timbers natural tendency towards moisture uptake and release i.e. by default you will be reducing the potential incidence of surface crazing (checking and splits), bow, cup, warp etc.

  • How long after the initial first coat of Wood X Clear hard wood decking oil to all four sides and ends, do you recommend a second coat be applied?

    Wood-X penetrating Deck Oil should be maintained or re-coated when the coatings’ properties have deteriorated. Loss of ability to ‘bead’ water is a good indicator. Re-coat times will be heavily dependent upon timber type and natural characteristics, degree of surface exposure to direct weathering, timber finish and amount of Wood-X Deck oil originally applied to the timber. In simple terms, when water repellent properties have been reduced, then a maintenance clean and coat should be carried out.

  • Does coating the hardwood deck with Wood X Clear Base Deck oil stop the deck from Silvering off.

    No

  • Can we lay the deck first and just apply one coat of Wood X Clear oil to the top seen face of the decking to cut down on the amount of wood oil required in the job. If the oil is that good it is going to migrate deep into the hardwood anyway.

    It is a false economy and we do not recommend this. Best practice is to apply the wood oil to all four sides plus cut ends before fixing into position. If it’s a case of coating an old deck that has been thoroughly and professionally cleaned (previous coatings and/or weathered grey surfaces stripped off) back to bare, fresh wood, then application to one face and two edges will be superior to no coating at all.

    Please remember that the rate and volume migration of Wood Oils into timbers will vary greatly with timber surface and species. Deep migration into dressed face hardwood timbers will be very slow and may require several coats and some years to achieve.

  • Can I coat my previously uncoated (fresh and new) treated Pine weatherboards with Wood-X Cedar oil?

    Yes you can, assuming they are solid timber and not finger-jointed weatherboards.

    Both treated and untreated, dry Radiata Pine readily accept mineral oil coatings. However, because of its’ denser cell structure than Western Red Cedar, penetration into Radiata Pine will likely be slower, if not marginally so. Don’t forget that Dressed Face boards will accept the coating a lot slower than band sawn.

    Wood-X wood oil fungicides won’t react with LOSP or CCA. If using LOSP, it is imperative to make sure the product has fully flared off prior to applying the wood oil. With CCA treated product, the timber must be dried to 19% or below before coating.

    Please also be aware that Pine can harbour more mould and spores than timbers that have more natural anti fungicides present in them, such as Western Red Cedar.

  • Can I apply Wood-X to my Pine Plywood cladding?

    Under test. Please check with the manufacturer of your plywood for guidance meanwhile.

  • Can I apply Wood-X to my Okoume/Cedar faced Plywood cladding?

    Under test. Please check with the manufacturer of your plywood for guidance meanwhile.

  • What adhesives and flexible sealants are suitable for use with Wood-X coated timber products?

    Wood-X has been tested by Bostik New Zealand Ltd and found to be compatible with Bostik Seal ‘N’ Flex 1 – Polyurethane Construction Joint Sealant. Bostik makes the following recommendations for use.

    – When applying Bostik Seal ’N’ Flex 1 Polyurethane Sealant to Cedar pre-coated with Wood-X Wood Oil, the Wood-X Oil must be touch dry.

    – When applying Wood-X Oil over Bostik Seal ‘N’ Flex 1 Polyurethane sealant, the Bostik Seal ’N’ Flex 1 Polyurethane Sealant must be fully cured (7 days minimum).

    Bostik Seal ’N’ Flex 1 Polyurethane Sealant is available in a number of colours. Bostik recommends selection of a colour closest to that available in the Wood-X Cedar Oil colour palette.

    These recommendations are based on testing completed with clean, dry Cedar on both Dressed and fresh Band sawn surfaces. Adhesion to Green or Weathered Cedar was not evaluated.

    A Technical Data Sheet for Bostik Seal ’N’ Flex 1 Polyurethane Sealant is available at www.bostik.co.nz.

  • I have had good experience in the past with another Wood Oil styled coating. Why should I change to Wood-X?

    If you are happy with the performance of your existing choice we are confident you will be at least as happy with the Wood-X Cedar Oil. With the technical support and experience of Resene we have endeavoured to advance Wood Oil coatings on three fronts.

    – Base Oil quality: A more highly refined oil was selected in preference to cheaper options as a means to noticeably improve the penetration and therefore surface dry time, of Wood-X Wood Oil. The value of this feature can not be understated, for so long as the Oil remains in excess on the timber surface it remains vulnerable to wash down and as a result, unavailable to provide the full benefit that only sub-surface water repellent oil can.

    – Biocide package: Internal testing and critical evaluation lead to the specification of a Resene biocide package with a long history of proven service in New Zealand conditions.

    – Colour Tones or Tints: Just as with the Biocide package, the best choice based on comparative evaluations, historic field performance and internal exposure testing was a special of tint bases from Resene’s Colourant Research and Development Lab.

  • I wish to lay an independently supported hardwood decking over a torched on butyl rubber membrane. Can I apply Wood-X Clear base hardwood decking oil in this situation? What are my options here?

     

    Our recommendation is that you check with your Butyl rubber supplier. Our earliest observations are that provided the Wood-X wood oil coating can be effectively wiped and cleaned from the butyl rubber surface immediately after coming together, the butyl membrane surface will be fine. However, informal testing through the immersion of butyl rubber in Wood-X Wood Oil and other similar Wood Oils has lead to a softening and disintegration of the rubber. Whilst the long term performance of Butyl rubber membranes exposed to medium-long term settling of Wood-X Wood Oil are yet to be proven, the immersion test results if indicative, are not encouraging.

  • Is Wood-X, either Clear Base or Colour Toned compatible with Herman Pacific’s Aluminium External/Internal/Cavity Closer flashings?

    Yes. There is no reaction between the aluminium and the Wood-X coating.

  • Does Wood-X degrade or impact any of the following standard Cedar fixing or flashing materials?

    Silicon Bronze nails – No

    Stainless Steel Nails (316 or 304) – No

    Stainless Steel screws (316 or 304) – No

    Aluminium flashings – No

    Copper Soakers – No

  • What is the expected shelf life of a container of Wood-X?

    Lid on correctly (firm and tight) we expect no degradation over a 3 – 5 year period. Storing oil / paint etc. should always be on a wooden shelf as opposed to concrete floor, as the latter by virtue of being a heat sink, suffers more extreme temperature changes.

  • How will I know when my pail of Wood-X has expired?

    The coating will have one or all of the following characteristics …

    (1) A sticky skin on the surface

    (2) A thicker consistency

    (3) An opaque, milky appearance.

  • How should Wood-X be stored?

    Wood-X should be stored with lid firmly in place, on a timber shelf or base in a well ventilated, dark area between 15 – 20 celsius. Wood-X must not be stored directly on to a concrete floor. Prolonged, intermittent exposure to direct sunlight and temperature extremes must be avoided as this could lead to a breakdown in the storage container and reduced life of the coating contents.

  • My Western Red Cedar weatherboards are to be supplied pre-coated by Machinecoat (NZ) Ltd. Will the pre-finished boards, fascia etc. look the same as the brush out Colour Toned sample on Cedar supplied to me?

    The answer is Yes and No. Western Red Cedar is famed for a number of attributes, including a wide range of grain patterns and natural colourings (light straw through reds to rich chocolate browns). Wood-X Cedar Oil with colour tone added is formulated to enhance Western Red Cedar’s natural, visual characters of colour and grain. The single, initial factory applied coat of Wood-X will enliven the timbers appearance with a fresh, oily or wet look and tend to dominate the selected colour tone in many, but not all boards. Oil take up between different boards may also vary somewhat with their density or grain orientation.

    While the initial coat will penetrate the timber surface and provide the additional benefit of moisture control, it also creates a base for subsequent coats to build colour tone volume and visibility. That is, it may only be with additional coats of Wood-X colour tone applied to our current guidelines that your Western Red Cedar cladding will take on a more uniform, true to colour appearance similar to your brush out sample.

    For your reference, Machinecoat (NZ) Ltd provides the following advisory with respect to final Colour versus Colour brush outs and Timber density.

    “The finish colour of your order will match with reasonable likeness any sample Colour Swatch or Brush Out available from Machinecoat (NZ) Ltd allowing for exposure to light and heat, timber grain, base colour and texture, sheen, area size, proximity and relationship to other colours and degree of transparency. It is likely that slight colour variation may occur in mixing and coating your order.

     

    Due to the varying density of timber, a Dressed Face (DF) timber surface may result in a patchy appearance once coated. It may take a site applied second or third coat to even up the broader colouring. The second or third coats must be applied to manufacturer’s specifications.”(LINK TO RELEVANT PAGE ON THE WOOD-X WEB SITE)

  • Is it okay to use a dark colour Wood-X to coat my Cedar weatherboards?

    Yes, but you need to be aware of the possible implications of doing so. A dark colour will attract undue heat and increase the incidence of instability in the cladding. Also, the expected performance of dark coatings is less than lighter colours.
