General

While Cutek products have proven to be highly successful for many years and in many countries, and are manufactured to the highest standards, Chemisys is unable to offer any specific performance warranties for the Cutek products because of the wide variation in applications possible. 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 reservations about using Cutek we recommend testing prior to use in sensitive applications. Please contact your closest retailer or contact Chemisys for a free test sample to enable you to determine the suitability of our products for your application.

Weather and Temperature

Timbers to be coated with Cutek Oils should be clean and dry, with an equilibrium moisture content of no higher than 17%, and moisture gradient of less than 1%. Do not apply Cutek Oils to exterior timbers if it is likely to rain within 24 hours of application.

Cold temperatures may increase the viscosity of Cutek Oils, tending to slow down the rate of diffusion. Storing containers in a warm place immediately prior to application will help alleviate this problem. Because Cutek Oil dries by diffusing into the timber substrate, application of a second coat of Cutek Oil too quickly after the first coat in cold weather will significantly delay the penetration and drying of the finished coating. If this inadvertently occurs, removal of excess Cutek Oil from the surface with a rag, will promote faster drying. Alternatively, the application of the second coat of Cutek Oil may be delayed for up to three months in cold weather, with no detrimental effect to the efficacy of the coating.

Adjacent Surfaces

While Cutek Oils, Cutek Proclean and Cutek CD33 Naked are safe and easy to use, always remember that these professional strength products, so care must be take to protect adjacent surfaces from inadvertant contact. Cutek Oils for example may stain concrete, while Cutek Proclean and Cutek CD33 Naked may dull, damage, or remove adjacent paintwork or coatings.

Surface Mould & Fungus

Clean looking timbers may be contaminated with mould spores, which are not readily identifiable with the naked eye. If timber in this condition is coated with Cutek Oil it is possible that dark staining may occur. If such staining inadvertently appears, refer to Proclean information.

Garage Doors

If the timber being coated is on a garage door and the glue holding the timber to the frame is either a rubber based adhesive, or you are uncertain; run a bead of glazing sealer along the back of the door where the timber meets the frame. This will ensure that the timbers will remain intact if the Cutek Oil weakens the adhesive.

Rubber & Butynol

Cutek will dissolve rubber based glues and adhesives, and will affect Butynol and rubber surfaces if not wiped off soon after contact is made. It also may affect some silicones. When Cutek Oils are applied to wooden shingles, it does not normally affect the Butynol underlay. Timber protected with Cutek Oils can become stained if it is in constant contact with bituminous type materials. Please contact Chemisys for a free test sample if you have any questions regarding the suitability of our products for your application.

Chemicals

Timber surfaces coated with Cutek Oils may show splash or spilling marks if contacted by chemically staining products such as wine, cleaner contaminated water, or strong chemicals. At risk areas include kitchens, bathrooms and spa-pool surrounds. Please contact Chemisys if you have any questions regarding the suitability of our products in these areas.

Cross Diffusion

Where plasterboard, plaster, or any other absorbent material abuts timber coated with Cutek Oils it is possible that cross diffusion into the porous substrate will occur. Please contact Chemisys if you have any questions regarding the suitability of our products for your application.

Leaching

Exterior painted or plastered surfaces situated below Cutek Oil protected timbers may become stained by leachate from above. If this inadvertently occurs contact your closest retailer for Cutek Proclean

Colour and Weathering

Please note that the natural colour of timbers can vary significantly. Clear and colourtoned Cutek coated timbers can fade and weather at different rates when exposed to the weather. Chemisys is unable to offer any specific performance warranties in relation to colour retention for Cutek products because of the wide number of variables related to this weathering process. 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, method of application, and adequacy of preparation. If you have any reservations about using Cutek we recommend testing prior to use in sensitive applications. Please contact your closest retailer or contact Chemisys for a free test sample to enable you to determine the suitability of our products for your application. Specially formulated colourtones are available to mix with ALL versions of clear Cutek oils to maintain the natural timber colour character, delay silvering, and retain the "freshly oiled look" for longer. When selecting from the range of colourtones allow for the timber colour to naturally lighten during the first three to eight months after application, as natural weathering and leaching occurs. Colour will last longer on rusticated, or band sawn timbers, and may be maximised by including the colourtone in all subsequent applications of Cutek oil. If colourtoned Cutek has faded over time, wash timbers with Cutek QuickClean or Cutek Proclean and apply a single coat of colourtoned Cutek CD50, Cutek Extreme or Cutek LowVOC to restore the original look of the protected timber.

Fastenings

Cutek Oils will not adversely affect hot dipped galvanised iron, silicon bronze, stainless steel or copper nails. Colour-toned Cutek Oils may lightly stain lead flashing and other substrates contacted by leachate.

Very Light Coloured Substrates

Cutek Oils contain small amounts of copper salts that may impart a faint green hue to very light or white substrates. Please contact Chemisys for a free sample of Cutek Oil to test on your light coloured substrate to determine suitability if you suspect this may be a problem.

Knots

When Cutek Oils are applied it diffuses deeply into the timber and displaces moisture. This reduction in moisture content may loosen some knots, particularly in very knotty timbers.

Colourtone and Colour Testpot Variations

While we make every effort to ensure consistancy of coloured products, it is occasionally possible that there may be a colour variation between made up product and testpots supplied. This may be due to differences in testpot and colourtone storage times and variations in raw material supplies. It is the sole responsibility of the applicator to ensure that the actual colour being applied is suitable for the intended purpose. Chemisys cannot and will not be liable for the application of any incorrect colour to any substrate for any reason. If you discover a variation or have any doubts about the accuracy of a coloured product, please contact Chemisys for advice and assistance.

Preservation

Cutek Oils are designed purely as a surface coating type product, and is in no way intended to replace licensed timber treatment processes.

Plywood

Application of Cutek Oils to some decorative plywoods with extremely thin top veneers may cause underlying dark veneer glue lines to become visible due to the penetration of Cutek Oil rendering the top veneer semi transparent. Please contact Chemisys for a free sample of Cutek Oil to test on your plywood substrate to determine suitability if you suspect this may be a problem.

Acetylated Wood

Cutek products are not suitable for use on acetylated wood
