Cutek oils deeply diffuse into timber and provide long lasting protection from within. This means that the wood will continue to resist water and remain stable even after the surface has faded or silvered, which means your exterior timber will last much longer, even if it has faded or gone grey.If you want to keep colour on the surface of your wood, then reapplication of Cutek oil with a colortone will be required, and the timeframe to reapply will vary depending on a number of factors. More frequent maintenance is required in fully exposed areas, or areas with heavy traffic. As an example, a fully exposed deck with heavy traffic will probably need cleaning and recoating every six months, whereas rough-sawn shingles on a protected wall will retain their colour and stability for many years after the initial application.
Unlike most coatings, it is not necessary to wait before applying Cutek to new timber. In fact we recommend that the first coat goes on as soon as possible to protect the wood during the construction phase.
Despite being a premium wood protection system, Cutek is very cost effective. The coverage rates are up to double those of other premium wood care products, and maintenance is simple – no sanding or stripping required. Many cheaper coatings on the market end up costing far more when the price of sanding or stripping before recoating is factored in. And the use of Cutek will add years to the useful life of exterior wood, meaning greatly reduced replacement costs. This makes Cutek an ideal choice for the budget conscious DIY, as well as for councils with kilometres of boardwalks and railings to maintain.
Natural oils have been used for years to protect timber. Nearly all work by cross-linking close to the surface of the wood to provide a barrier, which is similar in its effect to conventional film-forming products. Some natural oils provide nutrients that actually support the growth of unsightly wood discolouring fungi, mould and bacteria. Cutek oils are NOT natural oils.
Unlike other timber coatings, Cutek wood protection oils work by penetrating and stabilising timber rather than by encapsulation. Cutek products are the number one choice for outstanding protection and restoration of exterior timbers, with proven performance on hardwoods, softwoods and engineered timber. Cutek oils will penetrate deeply into any species of timber, including hardwoods and many engineered timbers, to provide water repellency and assist with long term dimensional stability. Cutek oils will not peel off or crack, but helps to control warping, cupping, and splitting; effectively enhancing the service life of timber. This characteristic ensures that future recoat preparation consists of a simple wash-down of the timber, rather than conventional sanding or stripping, resulting in significant savings in ongoing maintenance costs and time.
Cutek wood protection oils will not crack, peel or flake. However Cutek oils will fade gracefully over time at a rate determined by species, situation and aspect.
Cutek oils rely on deep diffusion and penetration into wood. Cutek oils will not dry on the surface until complete diffusion has occured. Factors that slow the rate of diffusion are:
1. Wet wood, or wood with a high moisture content. We state a maximum moisture content of 17%, as anything higher can significantly delay penetration, and the Cutek oil can sit on the surface and eventually go tacky without penetrating properly.
2. Cold weather. Cutek oils will become thicker when cold, and the tendency is to apply too much oil. Warming oil before application will make it thinner and enhance penetration.
3. Too many coats too soon. The first application of Cutek oils needs to completely diffuse and dry fully prior to the second or subsequent coats.
4. Existing oil, stain or paint on the surface. Existing film coats act as a barrier to Cutek oils penetration. Old coatings must be fully removed by sanding and or chemical stripping prior to application of Cutek oils.
Unlike most wood coatings and stains, Cutek Extreme migrates and diffuses very deeply into the wood before going dry at the surface, and this process takes varying amounts of time according to many different factors such as density, porosity, species, residual moisture content and temperature. Correspondingly, Cutek Extreme does not dry fast like most paints and has a cumulative effect in the wood. Recoating before the migration process of previous coats is finished is a waste of money and time.
NO. Cutek oils will not penetrate through other oils or stains as they represent a barrier to penetration. All oils, stains, paints and other films must be fully removed before Cutek oil is applied. Cleaning is not enough and heavy sanding, chemical stripping, or a combination of both are required to ensure all existing coating is removed.
Simply flick some cold water onto the surface of the timbers to be coated. If it soaks in, then it is OK to use Cutek oils.
Yes – Cutek oils are suitable for interior use. Generally only ONE COAT of clear is required. Cutek oil imparts a “matt-lowsheen” finish to smooth timbers, so in areas that are subject to high traffic or abrasion such as flooring, conventional polyurethane technology may provide a more satisfactory result. It is also important to ensure adequate ventilation when applying Cutek inside, and be aware that the solvent smell may remain for some time as Cutek penetrates the wood. We recommend testing prior to use in interior applications.
Use Cutek oils on new shingles to protect from feathering, splitting, and surface discoloration. Clear Cutek oils will protect your shingles while allowing them to naturally silver with age. Alternatively, you can use Cutek® Stabilising Oil with “Silvertone” or “Smokey Grey” colourtone to silver the shingles from the beginning.
While Cutek products have proven to be highly successful for many years and in many countries, and are manufactured to the highest standards, Chemisys does not, and is unable to, offer any warranty or performance guarantee for the use of Cutek products on any substrate. This is due to the large number of variables possible with the use of our products. These variables include but are not limited to; the age and porosity of the timber, species, situation, design and structure, aspect, differing exposure to the weather and adequacy of preparation. If you have any doubt about using Cutek products for your project, we can provide you with a free sample so that you may determine suitability of our products for your own purpose. Many different manufacturers choose to specify Cutek materials for use with their own products, but this does not mean that we are included or involved in any independent warranties issued by a specific manufacturer or distributor in relation to their own product.
