Maintenance of
surface treatment
–
Timber
When cleaning the
wooden parts with lukewarm water and a
neutral cleaning fluid, check for any damage
or wear to the surface treatment. If a degra-
ded surface treatment needs restoration, we
recommend the following procedure:
Cleaning
Thorough preparatory work is decisive for the
durability and adhesion of the treatment.
First, wash thoroughly with water and am-
monia or a strong cleaning agent (not dish
soap). Scrape off loose paint and remove any
resin with rubbing alcohol.
Priming
Exposed wood facing the outside environ-
ment must be primed with a clear wood pre-
servative or priming oil. When dry, sand all
surfaces and edges lightly with sandpaper
and remove the dust with a brush or cloth.
Finish
Finish with two coats of paint of the desi-
red colour. We recommend that you use the
same water-dilutable product as the ele-
ments were originally treated with. See the
nearest dealer above.
Anodised alu profiles are almost maintenan-
cefree provided that the surface is cleaned
a couple of times a year with a soft brush
or cloth and lukewarm water with a neutral
cleaning fluid such as car shampoo.
General facts about
surface treatments on
wood profiles
Resin lumps and discolouration from knots
All wood profiles from Idealcombi are quality
optimised, finger jointed/laminated ensu-
ring elimination of at least 95% of all knots,
star shakes and other defects. This gives the
wood profiles greater stability and signifi-
cantly reduces problems such as knot disco-
loration, yellow blotches and resin lumps in
the surface treatment.
Please bear in mind that wood is a natural
material, and as such resin lumps may form
underneath the paint and discoloration from
the wood treatment may occur – even with
the best surface treatment.
Small droplets of resin penetrating the paint
can easily be removed with rubbing alcohol.
If small lumps of resin form underneath the
paint, leave them for 2-3 years or until the
resin has penetrated the surface treatment,
then remove them with rubbing alcohol or,
in more serious cases, scrape and sandpa-
per them away before applying new paint.
Yellow discoloration, which can normally be
removed with rubbing alcohol, often occurs
on light colour finishes.
The above mentioned problems are often
more pronounced during hot summers (tro-
