By applying water

By applying water solvent varnishes once annually their durability can be extended. Micro fine cracks and pores in the coat of varnish are closed off, the surface can be re-finished any time. Large scale varnished and coated surfaces (e.g. frame profiles of front doors or full structure doors) require the use of the FRONT DOOR Care Set, or else streaking may occur. Maintenance intervals of varnished and coated surfaces: these are very dependent on several factors: Surface color, situation of installation, external environmental impact, intensity of sunshine and weathering ... In order to come up with any care and maintenance intervals, we recommend regular visual inspections of the coating and of the construction joints (max. every 6 months). If any chipping, damages by hail or any other damages have occurred, these should be fixed professionally immediately in order to prevent any subsequent damages. As wood material subjected to the elements can only withstand weathering to a limited degree, repairs of minor damages should take place immediately otherwise what began as insignificant “early damage” may quickly develop into a “total loss” which can not be salvaged. 8 KATZBECK-MANUAL

7. Care and Maintenance of Oil Stained Wood Surfaces: The high quality wood aluminium window (wood window) has been proofed, coated and finished with Aquawood larch oil stain by the manufacturer. Inside, occasional cleaning with warm water and a wet rag is all that is necessary in the care department. Adding mild neutralizing agents to the water is possible. Should subsequent painting become necessary due to surface damage, the previous coating has to be sanded with 80/100/120 grain sandpaper and then refinished twice with Aquawood larch oil stain – diluted by 10% water. It makes sense to perform a light 280 grain sanding down after the primary finish has dried. Outside (conventional wood windows), oil stains prove to have very limited suitability. It does not correspond to the Austrian standard (ÖNORM) B 3803 in regard to the thickness of the layer and UV protection. The dimensional accuracy of thickly coated surfaces cannot be achieved. Oil is degraded on the surface through the effects of sunlight and rain, therefore the windows have to be cared for subsequently and regularly. It is not possible to experience even weathering due to the varying weathering intensity at the window – the lower third is affected much more by weathering, the top part is typically protected from the effects of water much better based on the installation depth! Depending on the weathering intensity affecting the installation, Pullex wood stain has to be applied 1 – 2x per year for subsequent protection. The product needs to be applied thinly with a cotton cloth. Repeat after overnight drying in case of strong absorption. Only if regular and specific care is applied to prevent permanent greying of the wood base may oil stain coating be used for conventional windows. The restoration of wood that has greyed or is covered in wood colored mildew to the point of achieving a consistent surface is very difficult and simply impossible for a oil stained surface. 80/100/120 grain sandpaper has to be used to grind down to healthy wood in the damaged areas. Unimpaired areas have to be sanded longitudinally along the frame with 180 grain. The entire window has to be painted in the desired color twice using Pullex Silverwood. Switching to other coating products may result in adhesion issues (formation of bubbles) (not in case of the recommended restoration method). Caution: rags that have been soaked in oil stains, which oxydate when drying, may spontaneously combust! Allow soaked cloth to dry in a spread out manner; store in closed metal containers or under water. KATZBECK-MANUAL 9
