DOMUS and PATUS maintenance of external wood - full
Timber windows need maintenance. Not much though, if the work
gets done in time. Inspect regularly whether there are cracks
emerging in the exterior coating. This applies particularly on the
southern and western elevations, bays etc. where the sun's UV rays
are hard on all woodwork.
Just one crack in the paint exposes the timber to moisture, and
the decomposition of the timber has begun. The windows
must be reviewed once a year with a brush to make repairs to the
surface wherever they are needed. The timber moisture content
should be in the range between 15 and 18 percent and the air
temperature around 15 degrees. Avoid painting too early - wait for
the night dew to ease - and quit in time for the paint be "hand
dry" before the dew falls again. For post-treatment we recommend
the use of a paint with great covering power either water or oil
based in the appropriate colour. The paint applied in
the factory is water based in gloss 20. Furthermore it is a
good idea to wash the sash and frame a few times a year when you
clean the windows. This removes dirt and other contamination,
which ultimately degrades the surface. Use water with a mild

Twice per year, preferably during spring and autumn, the
cover coating must be washed with clear water with added suitable
ph-neutral cleaning agents in order to remove dust, insects and
other pollutants that could serve as a basis for infestation by
bacteria and fungi and other contaminations.
Then check the surface thoroughly for any damage. Any
damage identified must be treated as follows:
- As far as possible, sand only the damaged areas (grain
180-220) and remove the dust. Finally, treat with 2 x Aquatop
2600-TS 7129 (split acrylic paint brush).
- In the event of significant damage in the surface coat,
the whole frame section must be sanded. Take care not to sand off
the primer. Finally, treat the whole frame section with 2 x Aquatop
2600-24 tinted (split acrylic paint brush).
- Deeper instances of damage, which reveal untreated wood,
must be sanded and treated with Teknol Aqua 1410-01.When the
impregnation is dry, treat the area with 1 x Aquaprimer 2900-02
tinted. Finally, treat with 2x Aquatop 2600-24 tinted (split
acrylic paint brush).
- When painting, you must be aware of the following:
impregnation, priming and the surface product must not be applied
at temperatures of less than +8°C and humidity of more than 85%.
Water-dilutable products have a limited shelf life. In closed
packaging and when stored in a frost-free environment, they will
last for approx. 12-14 months.
ALDUS and PATUS+ maintenance of external
The outer aluminium reduces the need for maintenance. You can
make do with washing the outside of the window a few times a year.
It is best if you make it a habit to wash the sash and frame
whenever you clean the windows. If the window has been damaged
or physically stressed by other means, remove minor scratches with
a polishing compound.
DOMUS, ALDUS, PATUS, and PATUS+ care of interior
The inside of the window requires virtually no care to ensure
durability. But in most rooms it will from time to time be
necessary to remove grease and smoke from the sash and frame. The
cleaning frequency depends on the load the room is exposed to.
Clean with a cloth and mild detergent.
DOMUS, ALDUS, PATUS, and PATUS+ care of weather
Weather strips require no maintenance beyond routine cleaning
when needed. Use a cloth with a silicone care product to make
the strips remain soft. That's all.
If you would want to give your windows a new colour, be careful
not to get paint on the strips. If that happens, they
will lose their flexibility that is necessary for the window
or door to close tightly.
DOMUS, ALDUS, PATUS, and PATUS+ lubrication of hardware
Ironmongery parts do not require much care. However, it would
make sense a few times a year to give the moving parts few drops
of acid-free oil, so they continue to move smoothly. Use
oil for sewing machines, K-40 or similar. For parts
in exposed locations, e.g. coastal areas, the oiling
intervals are likely to be shorter than once a year. Under
extreme circumstances, a replacement of exposed fittings will be
needed after a few years. In addition, make sure to keep dirt
away from the various runners that some types of windows are
provided with, in order to always have fully functional

Use a soft brush and a squeegee, with a mild soapy water - if
necessary add a rinse agent that prevents calcium stains.
We recommend cleaning the exterior frame and sash twice a
year when cleaning the windows anyway. It is a good idea to open
the windows and wash all available surfaces, corners, etc. where
insects like to hide a couple of times a year. It is especially
important to remove cobwebs and the like, which in time will
inevitably sit in the corners and can block the automatic water
drainage and the natural ventilation around the frame.
Window Stickers on new windows can be removed by soaking them in
water. Remains of window stickers or other marks may be removed
with gentle use of ceramic hob cleaner.
