Timber products - care and maintenance

Initial Surface treatment

Our elements are manufactured from heartwood (pine) and are delivered in surface aqueous impregnated (2-ECO) version. Being manufactured of heartwood, our elements are dry rot proof. Yet, the elements must be painted and maintained properly in order to uphold the warranty and maintain their appearance and trouble free operation for many years.

Elements delivered untreated
As soon as possible after delivery, the elements must be primed to protect the surface against attack. Prime with SUPER SECU no. 2 wood preservation – or similar turpentine based preparation. If you wish to use water-based preparation, prime with DK-1 wood preservation, suitable for water-based treatment.
The priming must be followed by three layers of DK-5 wood preservation, water based or similar and must be rubbed down between the first and the second layer.
As a minimum the outside frame side must be primed before installation. The entire element must be treated immediately upon installation.
The elements must dry at a temperature higher than 5Cº.

Opaque treatments (paint) will normally last longer than translucent treatments (wood preservation). Colourless treatments are not adequate for protection against sunlight and fading – inside or outside. Our warranty lapses if colourless treatment is used.

Choose a system for surface treatment that is tested and approved in accordance with CEN/TC 139/WG2/N46 and follow the instructions given by the manufacturer regarding application, layer thickness etc. We recommend alkyl or plast- based preparation treatments.

Elements delivered treated
The treatment is done industrially, under normal circumstances with Teknos Schou’s products, which are ALKYL AND PLAST-ALKYL based. (Teknos Coatings Ltd – Unit E1, Heath Farm, Banbury Rd, Swerford OX7 4BN Tel 01608 683 494 Fax 01608 683487)
In some cases other treatment systems may have been used. If you have any queries, call Eurojoinery , stating the code standing on the DVC-label.

Resin spots
Wood is a living material. Formation of resin on the surface must be considered acceptable. If the resin is formed as little drops on the paint, it is possible to carefully wipe it off with spirits or turpentine – but be careful that the paint does not come off at the same time. If the resin is formed as spots under the paint, 2 or 3 years should go by before re-establishing the treatment. The resin may then be scraped or grinned away before finally painting the element.
Follow the instructions given under ”Maintenance”.
Discolouration may also occur as yellow patches in the surface.
