CUTEK® WOOD PRESERVATIVE

APVMA Approval No: 83026/107340

CUTEK® Wood Preservative is an oil based wood stabiliser used for the pre-treatment and remedial treatment of exterior wood in industrial and domestic situations.

CUTEK® Wood Preservative coated wood resists damage caused by fungal decay, mould, termites and moisture, improving dimensional stability and minimising warping, cupping and splitting.

Like CUTEK® Extreme CD50, CUTEK® Wood Preservative has been specially designed to withstand Australian conditions. Penetrating deeply into the timber, the protective properties within CUTEK® Wood Preservative repel moisture to improve the service life of timber.

CUTEK® Wood Preservative is easy to use and will not peel or flake, making maintenance fast and simple. Applied as a clear oil, CUTEK Wood Preservative will allow timber to naturally silver over time. Mixing in one of 16 CUTEK® Colourtones will help to enhance and maintain the freshly oiled natural look of your timber or alter your timber colour to meet your design requirements.

CUTEK® Wood Preservative is the best choice for large scale commercial and government projects.

CUTEK® WOOD PRESERVATIVE OFFERS SUPERIOR PENETRATION AND DIFFUSION WITH A SELF-HEALING EFFECT

CUTEK® wood oils work differently to traditional wood stain/wood oil/acrylic/urethane/natural oils/wood coating products in that CUTEK® oils protect your timber from the inside out. CUTEK® oils penetrate and diffuse deeply into the wood core upon application, protecting it from the damaging effects of liquid and gas phase moisture, significantly increasing the service life of your timber. It does this by remaining PERMANENTLY MOBILE inside the wood, migrating to any cut or perforation with a self-healing action.

Many opposition products claim to be a penetrating oil finish; however, they often contain a mixture of solvents, polymers and cross-linking natural oils (such as linseed and tung oils) that penetrate only a few millimetres before drying to form an encapsulating type varnish. Because these coatings do not have a self-healing effect, once this varnish is exposed to the weather, water can quickly enter the core of the timber especially if it has been cut or perforated with fasteners leading to a rapid loss of dimensional stability. Additionally, the use of some natural oils in wood coatings can contribute to the development of unsightly mould and fungal growth underneath subsequently applied coatings. This situation can be difficult and costly to fix.

PREPARATION

STEP 1 PREPARE

In order for CUTEK® Wood Preservative to function properly, it is essential that it diffuses deeply into the timber. Anything that might prevent this enetration/diffusion, such as an existing coating (not CUTEK® oil), retained oisture, or insufficient time between coats, must be avoided or corrected before applying CUTEK® Wood Preservative.

CUTEK® Wood Preservative must be applied to wood that is clean, non-greasy and dry (moisture content must be less than 17%). You must appropriately prepare your timber BEFORE applying CUTEK® Wood Preservative.

If you have… NEW TIMBER:

Your timber must be bare, clean and dry before applying CUTEK® Wood Preservative. If your timber presents with surface contaminants such as stains caused by water, iron or tannins, we recommend using CUTEK® Restore prior to application of CUTEK® Wood Preservative.

If you have… OLD, GREYED OR WEATHERED UNCOATED WOOD:

Old, dirty, stained or grey weathered timber should be prepared and restored by first applying CUTEK® Restore which will remove the grey and reinstate the original natural colour, grain and beauty of your wood prior to application of CUTEK® Wood Preservative.

If you have… WOOD PREVIOUSLY COATED WITH A NON-CUTEK® COATING:

CUTEK® Wood Preservative must be applied to bare, clean and dry wood. This allows the CUTEK® oil to freely penetrate/diffuse into your timber. Wood previously coated with a film forming product such as stains, linseed oil, paint, polyurethane, water-based oils, etc. can inhibit this penetration/diffusion and must be removed first with CUTEK® Wood Stripper and CUTEK® Restore prior to the application of CUTEK® Wood Preservative. In some circumstances complete removal of previous oatings by machine sanding/abrasion can also be a suitable preparation method.

If you have… WOOD PREVIOUSLY COATED IN CUTEK® EXTREME CD50 OR CUTEK® WOOD PRESERVATIVE:

Prepare for a maintenance recoat of CUTEK® Wood Preservative by using CUTEK® Quickclean to remove grease, grime and other dirt from your timber. If maintenance has been neglected for a long period of time and the timber has either greyed, become heavily stained by tannins or iron, or if there is an excessive build-up of CUTEK® Colourtone, use CUTEK® Restore to refresh your timber prior to recoating.

Important information before proceeding:

A significant amount of new timber is now sold with a pre-treatment or pre-coating already applied. Particular attention needs to be paid to ensure that your timber has not been pre-treated or pre-coated prior to applying CUTEK® Wood Preservative. If you believe that your timber has had a prior treatment/coating applied, you will need to adequately prepare your timber as per the instructions above. If you have any questions about this process, please contact one of our friendly technical advisers on 1300 1 CUTEK (1300 1 28835). NOTE: This warning does not apply to any timber that has been pre-coated in CUTEK® branded products.

HOW TO APPLY

STEP 2 PROTECT
Before you protect:

Before you begin, note the hazards and precautions on this website and the can labelling, and ensure that you use the correct safety equipment as detailed in the Safety Data Sheet.

Weather:

Once applied, CUTEK® Wood Preservative generally requires 2-3 days of dry conditions after coating to facilitate full penetration/diffusion and an even colour finish; so check your weather forecast before coating.

Colourtone:

Clear, un-tinted CUTEK® Wood Preservative will allow your wood to naturally lighten/silver/grey when exposed to sunlight while retaining its protection characteristics. Unless you want a clear finish that will naturally lighten/silver/grey off in a few months, it is important to mix in 1 CUTEK® Colourtone to this can of oil before use. Adding a CUTEK® Colourtone provides UV colour protection and slows the lightening/silvering process.

To choose which Colourtone suits your timber and project, visit our Colourtone page.

Note: CUTEK® Wood Preservative diffuses deeply into your timber and will continue to provide moisture protection and improve dimensional stability even if a CUTEK® Colourtone is not added and your wood becomes weathered and greyed.

Application:

After preparing your timber, it will need to be completely dry prior to coating with CUTEK® Wood Preservative. It is very important that your timber is clean, non-greasy and dry with a moisture content of less than 17%. It is also very important that the surface of the wood is free from chemical residues and is not exposed to environmental contaminants such as dusts while Cutek is drying.

Stir the CUTEK® Wood Preservative oil thoroughly (with the added CUTEK® Colourtone if desired) before and during use. Make sure you stir from the bottom of the can to ensure active ingredients are properly mixed throughout the oil.

Apply thin, even coats with a brush, paint pad or lambswool applicator. CUTEK®’s DeckBoss brush is a good option. CUTEK® Wood Preservative works best when applied as a THIN COAT – two or three thin coats on finished wood and hardwoods are much better than one or two thick coats. For best results, ONE coat of CUTEK® Wood Preservative should be applied to all faces of the wood prior to installing, with a SECOND coat applied to the top surface once the first coat has completely penetrated/diffused.

Drying time:

Unlike traditional wood coatings, CUTEK® Wood Preservative needs to penetrate/diffuse deeply into your timber. After coating, CUTEK® Wood Preservative will slowly migrate into your wood to repel moisture, improve dimensional stability and lengthen the service life of your timber. This penetration/diffusion process varies in time for many reasons including differences in timber type (species, density, porosity, age of timber and residual moisture content) as well as environmental factors (temperature, humidity, weather).

Sometimes this drying process can take several days to complete. You will know when your timber is ready for a recoat of CUTEK® Wood Preservative when it is completely dry and non-greasy. Please note the second coat of CUTEK® Wood Preservative will take longer to migrate into your timber than the first coat.

Clean-up:

Equipment (including brushes) may be cleaned with turps or soap and water. If not correctly cleaned or disposed of, oily rags and other oily materials may cause combustion fires. After use you MUST immediately spread out all oily material outside to dry, by flattening them out to their full size in an airy spot at temperatures above 4 degrees Celsius, or wash them thoroughly with water and detergent and rinse. Remove all oil from all clothes, tools, rags and any other materials contacted during use or as a result of an accidental spill. Ensure wash water is disposed in accordance with local regulations.

MAINTENANCE

With CUTEK® oils, maintenance is simple, fast, and cost effective. CUTEK® Wood Preservative will not crack, peel or split, and your wood can be easily rejuvenated or restored using our Prepare and Protect system – no need to sand or strip.

CUTEK® Wood Preservative should be reapplied when the wood is no longer beading water, or as frequently as necessary to retain the natural beauty and colour of the wood.

Typically, horizontal exterior wood surfaces exposed to full weather such as pool decks and handrails will require re-coating more frequently (initially after 6 months, then annually), while other surfaces such as vertical rough-sawn cladding will need recoating less often.
