Maintenance products – even in the best products defects can occur from time to time

Professional installation and regular cleaning and maintenance are essential in order for your customers to enjoy long-term pleasure from their windows and house doors. This also allows the renovation intervals to be extended.

Right protection for wooden windows

In order to avoid damage to the frame, sash or glass during installation, cleaning or painting, all surfaces around the window should be carefully protected. The foil and tape used must be free of plasticizers and solvents as well as be UV- and weather-proof (e.g. TESA 4438). Please never leave the wooden elements masked or covered for more than two weeks otherwise moisture could harmfully build-up in the wood. All plaster work and painting should be completed within three months of installation.

Maintenance of surface coating

The coating of your wooden windows should be annually checked and maintained at regular intervals. Depending on the installation type, we recommend applying opaque coatings after 4 to 5 years and translucent coatings after 2 to 3 years. You can use eco-friendly, waterborne Sikkens Wood Coatings products for maintenance purposes.
