Cutek CD 50 – for Exterior Timber
A finish that preserves & enhances the natural character and beauty of wood.
Cutek® Wood Preservative is a specially formulated oil timber preservative for interior & exterior use, that is designed to penetrate deeply into any species of timber, including hardwoods, to provide water repellency, and assist with dimensional stability.
Cutek® Wood Preservative does 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 Preservative, is resistant to surface fungus and mould.
Cutek® Wood Preservative is suitable for use as a clear, water repellent preservative coating on exterior timber surfaces, however the clear coated timber surface will lightly silver with age to produce a natural weathered appearance, while retaining its dimensional stability characteristics. If this natural silvering of the timber is undesirable, then colourtoned Cutek Wood Preservative must be used to delay the silvering process in addition to maintaining and enhancing the natural colour of freshly oiled timber.
Cutek® Wood Preservative is suitable for use on weatherboards, shingles, board & batten, plywood, cane, log buildings, beams, outdoor furniture, deckings, fascia boards, shutters, garage doors, joinery, spa pools, fences, posts, … in fact virtually anything made of wood.
If your order with TIMBECK is for prefinished product and Cutek CD50 is selected as your choice of finish, it is applied in our coating plant with spray equipment.
Should you choose to apply this product yourself, the following is the Cutek recommendations for Cutek CD 50.
How To Use Cutek® Wood Preservative
In order for Cutek® Wood Preservative to function properly, it is essential that it is able to diffuse deeply into the timber. Correspondingly, any situations that would inhibit this free diffusion such as retained moisture, insufficient time between coats, or the presence of any surface sealant or barrier, must be avoided or satisfactorily remedied by correct procedure and product selection.
Additionally, timbers to be coated with Cutek® Wood Preservative should be clean and dry, with an equilibrium moisture content of no higher than 17%, and moisture gradient of less than 1%.
On New Timbers, it is recommended that one coat of Cutek® Wood Preservative be applied to all faces of the timber prior to fixing, and a second coat of Cutek® Wood Preservative be applied a minimum of two weeks after application of the first coat.
Always ensure that sufficient time is allowed for penetration of Cutek® Wood Preservative into the substrate before re-application, as actual recoat time may vary according to factors such as substrate temperature, density, porosity or retained moisture content. Thicker timbers such as posts, beams and logs will require additional coats of Cutek® Wood Preservative in order to obtain adequate protection, as Cutek® Wood Preservative has a cumulative effective in the wood with each application.
Apply liberally with spray, brush, speed-brush or roller while removing drips and sags as necessary. When using colour-toned Cutek® Wood Preservative it is essential that the pail be stirred frequently before and during use. The more Cutek® Wood Preservative that is absorbed, the longer the coating will last. Equipment may be cleaned with detergent and water, or mineral turpentine.
These figures represent typical averages for cladding timbers such as Western Red Cedar.
- New timber dressed 10 – 15 sq mtr/litre
- New timber rusticated or band sawn 7 – 9 sq mtr/litre
- Shingles and shakes 2 – 5 sq mtr/litre
Cutek® Wood Preservative must be reapplied as frequently as necessary to retain the natural beauty and colour of the timber. Recoat time varies widely according to the age and porosity of the timber, species, situation, and exposure to the weather. Typically horizontal exterior smooth surfaces exposed to full weather such as pool decks and handrails, may require annual maintenance, while vertical rough-sawn weathersiding may require maintenance less frequently.
CUTEK Oils provide an excellent finish on external Western Red Cedar.
Five of their standard colours (and CLEAR) have been applied to a random range of
colour mix Cedar to illustrate the final result obtained with two coats.
For external applications, the second coat is recommended.
