Wood: There is hardly any material
which is more versatile. In both
design and construction, wood
plays an important role as a univer-
sally usable and renewable raw
material. Its natural appearance is
particularly appreciated. However,
this natural appearance is also a big
challenge. As a natural construction
material, wood is highly demanding
with a limited service life. Proper
precautions – from careful design
planning to regular maintenance –
prevent early deterioration and con-
tribute to conserving long-lasting
value.
Different types of wood
Wood is divided in two categories:
coniferous, also referred to as soft-
wood; and deciduous, also referred
to as hardwood. Typical features of
coniferous wood such as pine and
spruce include fast growth and
homogenous structure. It is also
lighter and softer than deciduous
wood.
Deciduous wood such as oak or
robinia has a higher gross density
and is more difficult to process due
to its hardness and more complex
structure. A fine grain and the fact
that the growth rings are very close
to one another are characteristic
features of deciduous wood.
Tropical deciduous wood such as
teak or meranti is particularly hard
and long-lived. Typical features also
include a distinct mostly reddish
color. However, the wood will turn
gray if it is not sufficiently protected.
For a detailed assessment each
type of wood must be considered
separately. This is done using the
classification according to EN
350-2. This standard categorizes
different types of wood into dura -
bility classes according to their
resistance to fungi.

Common spruce
Larch
Pine
Douglas fir

Swelling and shrinking
Depending on relative humidity, the
moisture content of wood adjusts to
environmental climate. Variations in
moisture content result in volumet-
ric changes of the wood, referred to
as swelling and shrinking. Coatings
reduce or prevent these processes.
An exact determination of the type
of wood is often not possible, even
for experts. However, features such
as grain indicate the type and qua -
lity of the wood to be coated.
When a radial or rift cut is made
longitudinally through the middle of
the trunk of a tree the growth rings
run almost parallel. This suggests a
low swelling or shrinking tendency.
When a cross-section or end-
grain cut is done perpendicularly
to the trunk, the ring structure is
visible. This indicates a medium
tendency to swelling or shrinking.
A tangential flat cut runs longitudi-
nally outside of the middle of the
trunk. Due to the tapering of the
trunk the growth rings appear in a
parabolic shape. Wooden structures
with this visually attractive grain
have a high swelling or shrinking
tendency.
In the case of extreme growth ring
widths or unsuitable finger jointing,
we recommend issuing a warning
regarding inferior wood quality.

A matter of definition: the dimensional accuracy of wooden components/structures
Choosing the right wood coating
also depends on dimensional accu-
racy. This defines how much the
dimensions of a wooden compo-
nent/structure may change by
shrinking or swelling. The following
categories are used: components/
structures without dimensional
accuracy, components/structures
with limited dimensional accuracy,
and dimensionally accurate compo-
nents/structures. Each of these cat-
egories requires a specific coating
build-up.
Dimensionally accurate wooden
components/structures may
change their dimensions only within
a very small tolerance range. Exam-
ples of such components/structures
are windows, exterior doors and
accurately mortised or glued win-
dow and door shutters.
In the case of wood components/
structures with limited dimen-
sional accuracy, dimensional
changes are allowable to a limited
extent. This applies to tongue and
groove paneling, garden furniture,
half-timbering, roof undersides and
cornices as well as exterior doors,
and window and door shutters
unless these components are not
already categorized in the dimen-
sionally accurate group.
Components/structures without
dimensional accuracy are not
limited regarding volumetric
changes such as swelling and
shrinking. Typical examples are
exterior paneling with open joints,
weather boarding on lath grids,
overlapping paneling, shingles,
palisades, wooden grids and fences.

Wood: Natural beauty needs effective long-term protection
The natural beauty of wood used
in exterior applications is endan-
gered by UV radiation, moisture
and temperature changes. Effective
long-term protection requires an
object-specific combination of
� careful design and
� chemical and
� physical
protection precautions.
Wood protection by design
Appropriate measures should have
already been considered in the
design and planning phase in order
to protect wooden structures
against moisture. Unobstructed
draining of rain and condensation
water must be guaranteed. Design
or planning errors cannot be com-
pensated for later even by using the
best coating system. The following
considerations are particularly
important:
� Sufficient eaves projection
Roof eaves projections should be
dimensioned such that wooden
components/structures are protected
against direct weather impact as
much as possible. In areas exposed
to splash water, wooden components/
structures should not be used at all.
� Protecting grain-cut wood
surfaces
Grain-cut wood surfaces absorb
moisture very easily and have a
high swelling capacity. This is why
grain-cut wood should not be
exposed to direct weather impact.
� Drip edges
Drip edges are used for draining
water as quickly as possible.
� Round edges
In the case of dimensionally accu-
rate wooden structures/components
such as windows all edges must be
rounded in order to obtain proper
edge protection with a sufficient
film thickness.
� Avoid soil contact!
Negative example:No protection against sun, rain and wind impact.(© mauritius images/ Klaus Hackenberg)
Positive example:The wooden components/structures
are well protected.

Chemical wood protection
Chemical wood protection should
always be used selectively and only
if necessary because of the type of
wood used and the object situation,
and only in those areas where it is
actually needed – which is deep
inside the wood. For this reason the
impregnation must have a high
penetration capacity. This require-
ment is met by Impredur Wood
Impregnating Primer 550 because it
penetrates deeply into wood pores.
Its effectiveness has been docu-
mented by the recognized RAL test
institute and is certified by the RAL
Quality Seal. Impredur Wood
Impregnating Primer 550 is perfect
for protecting non-soil contact
exterior wood not exposed to static
load as well as for windows and
outside doors for protection against
decay and blue stain.
Physical wood protection
Physical wood protection comple-
ments design measures and chemi-
cal protection. Suitable coatings are
used to protect the wood against
weather impact and to give the
surface the desired look. You will
find a selection of products for all
physical wood protection require-
ments on pages 24 and 25 of this
brochure.

Coatings for wooden components/
structures must meet the highest
requirements. They should be easy
to use, flow readily and contribute
to effective long-term protection.
Brillux wood coatings meet these
requirements perfectly. Plus the
complete Brillux range of aromat-
ics-free and water-dilutable paints
and varnishes clearly proves that
meeting maximum quality require-
ments while ensuring health protec-
tion and environmental compatibility
all at the same time is certainly
possible.
Perfect products for any
application
Regardless of the requirements to
be met and regardless of whether
dimensionally accurate components/
structures or components/structures
with limited or non-dimensional
accuracy are concerned, Brillux
wood coatings are high quality
products which professional users
can rely on when it comes to effec-
tive long-term protection and the
value conservation of buildings.
With dimensionally accurate com-
ponents/structures, a long-life pro-
tection film which must not become
brittle with age is a primary consid-
eration. Good penetration and
expansion capacity are the main
requirements the coatings used for
components/structures without
dimensional accuracy have to meet
in order to compensate for swelling
and shrinking.
Quality you can rely on
Hardness test under extreme
conditions
In an outdoor weather impact test
Brillux wood coatings are applied on
different types of wood and exposed
to wind, rain, frost and sun for one
year. The test arrangement (inclina-
tion 45°, southern orientation) sim-
ulates a normal weather exposure
of about five years.

The first choice:
Brillux aromatics-free products
Use isoparaffin instead of white
spirit. This is the recipe for the suc-
cess of our aromatics-free alkyd
resin-based paints, varnishes and
primers. These products distinguish
themselves by their excellent appli-
cation and product properties while
reducing annoying smell by a factor
of 60. In addition the solvent
isoparaffin is much more healthy
and environmentally compatible
than white spirit. For this reason our
aromatics-free paints, varnishes
and primers are the first choice in
critical environments such as hospi-
tals, nursery schools and hotels and
restaurants.
The VOC issue: high quality
without compromise
Our motto is Quality Comes First.
Whether solvent or water-based,
we can offer you the right VOC-
compliant product for your appli -
cation. Thanks to intensive R&D
work we have succeeded in devel-
oping and marketing VOC 2010
compliant products in our typical
uncompromising professional qua -
lity, ensuring maximum environ-
mental compatibility and meeting
all legal regulations. You can be
sure you will always be on the safe
side with Brillux.
The ED50 value describing relativesmell intensity is about 1/60 thevalue of white spirit if isoparaffin is used.

Go on the color offensive
A high-quality coating build-up not
only has protective but also aes-
thetic functions. Architects and their
customers place particular empha-
sis on individual color design so
preferences and specifications are
carefully considered. With Brillux
wood coatings you have unlimited
design options reconciling appear-
ance and functionality issues per-
fectly. Thanks to our unlimited vari-
ety of color shades realization of
even the most exclusive wishes of
your customers is possible.
Wood – totally natural
Insufficiently protected wood sur-
faces will soon turn gray. This is a
fact many customers don’t want to
accept. With our wide range of var-
nish products you always have a
solution at hand. A solution which
maintains the visual and natural
appearance of wooden compo-
nents/structures for a long time.
Whether it comes to renovating his-
toric buildings or implementing
modern design approaches, you will
always have the right answer for
any issue. Even those who love the
gray color shades which form as a
result of unprotected permanent
weather and UV exposure will find
the right solution: Brillux varnishes
are available in various gray shades
for use in modern, architectural
close-to-nature-building concepts.
Go on the color offensive
Unlimited color shade variety for
covering coatings
When using covering coatings on
wooden components/structures the
demand for satisfying both sus-
tained wood protection and cus-
tomers’ aesthetic requirements can
be reconciled as well. With Scala,
the multiple prize-winning color
system developed by Brillux, any
color design task can be solved
quickly, effectively and true-to-style.
Color design without risks
Pigmented coating of wooden sur-
faces is great for effective design
accents. However, strong sun
impact can result in extreme heat-
ing of the wood when using dark
paints and varnishes. Possible con-
sequences of this thermal stress
include cracking and resin outflow.
In this situation the best long-term
protection is obtained by using
coatings in the light to medium
color shade range.

The Brillux practice tip: lightening technique for experts
In facade renovation everything has
to be light and friendly. But perhaps
there are dark-varnished window
frames and weathered balcony
balustrades and the customer
wants to maintain their characteris-
tic wood appearance. For this rea-
son a typical covering paint coat
cannot be used. There is only one
solution: lightening!
The lightening technique is used
when existing dark wood structures
must be adjusted to other surfaces
of components/structures such as
new windows or doors. Experts
achieve the desired effect by apply-
ing a well-chosen combination of a
covering primer coat and varnishing
topcoat.
1. The covering prime coat
In order to obtain a uniform, bright
substrate, the dark wood is first
coated with a primer. We recom-
mend Impredur Primer 835 with its
excellent moisture regulating pro-
perties. It can easily be tinted using
the Brillux Color System.
2. The varnishing topcoat
The subsequent topcoat (and inter-
mediate coat if required) is done
using a varnish which is always
applied slightly streakily in the
direction of the wood grain. This
way the desired varnishing effect is
obtained by outlining the grain. Our
Permanent Protection Woodstain
580 is particularly suitable for inter-
mediate coats and topcoats.
3. A perfect result
A perfect result is obtained by the
interaction of covering primer coat
and varnishing topcoat.

Moisture, temperature variations
and UV radiation: Exterior wooden
components/structures have to take
a lot. The effects of the sun are
often underrated. Short-wave UV
radiation impact damages the two
most important constituents of
wood: cellulose and lignin. UV radia-
tion has a particularly detrimental
effect on lignin which is embedded
in the wood’s cellular walls like a
paste and provides stability and
hardness. Energy-rich UV radiation
decomposes lignin over time. The
consequences:
� Color changes (whitish to dirty-
grayish)
� Gloss reduction
� Chalking effects
� UV permeable coats loose adhe-
sion and flake off
� Cracks form in the coat, providing
points of attack for fungi which
can damage the interior wood
which was initially only surface-
damaged
Our recipe for healthy wood:high-tech against UV radiation
Three-fold long-term protection
Thanks to their special pigmentation
all Brillux varnishes provide very
good protection against sun impact
despite their uniform transparency.
Permanent Protection Woodstain
580 features additional protection
against UV radiation, which makes
it the perfect solution when it
comes to effective long-term pro-
tection:
� Equipped with anti-UV pigments
� Additional UV absorbers filter the
radiation which damages wood.
Highly effective additives allow
visible light to enter and ensure
that varnish and color are not
affected.
� So-called radical traps minimize
decay processes in both the var-
nish film and wood cells. Untreat-
ed wood can quickly turn gray as
a result of UV radiation and poor
architectural design.

Before it gets too moldy: Brillux Protect
In addition to soiling, microorga-
nisms are more and more a pro-
blem for exterior surfaces. Due to
the reduced SO2 concentration of
the air and the escalation of airbor-
ne nitrogen combinations, facades,
roof undersides and other structu-
res are increasingly being attacked
by algae and fungi. These can affect
visual appearance significantly,
which could result in them possibly
being regarded as a flaw and lead
to legal action. Protection against
algae and fungal attack is not only
good for the appearance of your
facade but also conserves the value
of the whole house. Potentially
endangered facades should be
identified as early as possible in
order to take appropriate preventive
action. Protect, the flexible protecti-
on concept by Brillux, provides film
protection of the facade coating for
many different types of surfaces
including wood.
Algae and fungal attack risk
factors:
Endangered facades:
� All moist surfaces
� Buildings without eaves
� Defective downpipes
� Shaded areas
� Vegetation or water sources in
close vicinity
Endangered wooden structures:
� Surfaces with high moisture
impact and low sun exposure
� Roof undersides
� Carports
Protect: the ideal solution against
microorganisms
The Protect concept developed by
Brillux offers high resistance against
microbial impact on coats for all
substrates and in all colors. Nume-
rous plasters, facade paints and
wood coats are available in Protect
quality.
Nothing is forever
It is not always possible to guaran-
tee long-lasting freedom from algae
and fungi because many important
factors cannot be influenced at all
or only to a limited extent. All meas-
ures aim at delaying the spread of
microorganisms as much as possi-
ble, with Brillux Protect being the
ideal solution.
A typical risk is in areas of permanentshade which create an ideal
microclimate for fungi and algae.
Surface fungi spreading on facade surfaces and roof under-sides create flaws strongly affecting the general appearance of a building.

There is a range of standards and
rules regulating new and refurbish-
ment coatings for exterior wood
components/structures. They pro-
vide information on the special
properties of wood substrates and
the effect of different coating mate-
rials, indicate testing methods, pro-
vide processing/application tips and
specify the measures to be taken in
certain situations at certain times.
In addition to these standards the
applicable local legal requirements
of the country where the products
are used must be met.
DIN EN 350-2
DIN EN 350-2 (Durability of wood
and wood-based products - Natural
durability of solid wood) divides
wood types into classes according
to their resistance to wood-destroy-
ing fungi, microorganisms and
insects (also refer to the table on
page 5).
16
Important standards and rules for wood coating
BFS leaflet no. 18 (Germany)
Leaflet no. 18 (Coatings on wood
and wood-based materials in exteri-
or areas) provides detailed informa-
tion on wood as a building material,
substrate tests and coating build-
ups – both for dimensionally accu-
rate components/structures and for
components/structures with limited
or no dimensional accuracy. It also
describes the technical rules for
coating wood or wood-based com-
ponents/structures used in building
construction.
In addition, this leaflet contains
information on the strain conditions
of coatings. In this context leaflet
no. 18 refers to DIN EN 927-1
(Coating materials and coating sys-
tems for exterior wood).
The strain conditions not only
depend on the prevailing climatic
conditions but also on the protec-
tion provided by design/structural
measures, such as roofing or soffits
(see table below).
Data sheets
In general the specifications and
application/processing instructions
provided by the product manufac-
turer must be complied with for any
painting work to have the desired
result.
In addition, the object situation must
be analyzed, potential causes of
damage must be identified and cor-
responding measures must be
specified and taken if applicable.

1. Nitro test
One way of identifying the type of
existing coat is the so-called nitro
test. In this test the surface is wet-
ted with Nitro Thinner 456. If the
existing coat dissolves significantly,
it is a physically drying system, e.g.
a polymer resin or dispersion coat-
ing. If it does not dissolve or if it
only dissolves a little bit, this is a
sign of a chemically hardening sys-
tem, e.g. based on alkyd resin paint.
2. Bearing capacity
To check the bearing capacity of the
existing coat, a scratch test is wide-
ly used. The surface is scratched
using a scraper or knife and then an
adhesive tape is pressed on firmly
and pulled off quickly. If the coating
does not withstand this test, it must
be removed. In the case of var-
nished wood, a wet cloth is placed
on the surface to check if the exist-
ing paint coat and/or the wood have
effloresced. If a moist, dark stain
forms in the wood after a short
time, the weathered wood/coat
must be removed down to the bare
wood.
Regardless of whether a wooden
component/structure is varnished or
provided with a covering coat, suc-
cessful renovation depends on per-
fect preparation. Perfect preparation
starts with careful inspection of the
substrate. What type of existing
coat is it? What about the bearing
capacity? Is the moisture content of
the wood okay? The topcoat color
can also have a significant influ-
ence on the weather resistance of
the coating. Is the chosen color the
right one for this application? Let's
look at this step by step.
3. Moisture content
The moisture content of wood is a
particularly critical issue. The fol-
lowing limits are permissible before
coating deciduous and coniferous
wood:
Dimensionally accurate compo-
nents/structures: 13 % ± 2 %.
Components/structures with limited
or without dimensional accuracy:
< 18 %.
The current value can be deter-
mined using our Brillux moisture
meter.
4. Decay or insect infestation
Are there signs of decay or insect
infestation? If so any damaged
wooden components/structures
must be replaced.
Perfect coating down to bare wood

How to prepare the job properly
Perfect renovation coating is always
the result of careful preparation.
With dimensionally accurate wood-
en components/structures it is cru-
cial that the surfaces to be coated
are carefully prepared to ensure
that the coating build-up will result
in a closed surface.
Perfect renovating: Proper preparation is everything
1. Putty or sealing materials
Remove defective sealing materials
using a cup cut knife; in the case of
single glazing remove defective
putty using a hacking knife.
2. Sanding
First grayed wood and bearing old
coats are uniformly sanded using
delta grinder Festool Deltex DX 93
E-Plus 3241.
3. Extending open corner
connections
Cracked corner connections must
be extended to obtain a joint about
five mm. wide. The joint can be
filled using Window Repair Sealer
399 after applying the intermediate
coat.
For varnish coating:
1. Remove old varnish coats
Old, non-bearing varnish coats
must be removed carefully. A paint
scraper is the perfect tool for doing
this. Scraping should always be
done in the direction of the grain.
2. Sanding
Then the surface must be sanded
thoroughly. As an alternative to
a sander a bench grinder may be
used.
As good as new: renovating
using covering coatings
In the case of covering coating a
closed glossy or silk-glossy surface
is favored over the typical character
of the wood structure. These coat-
ings – in particular in light colors –
provide wooden windows and
exterior doors with the most reliable
long-term protection against many
types of exposure.
1. Impregnation
After pretreatment raw wood is
prepared for the subsequent coating
build-up using Impredur Wood
Impregnating Primer 550. This
deep-penetrating, moisture-regulat-
ing impregnation protects wood
against blue stain and decay.
2. Primer and intermediate coat
Priming and intermediate coating
using Impredur Primer 835 or
Impredur Ventipaint 822 supports
the moisture-regulating effect
perfectly. Both products are charac-
terized by excellent adhesiveness
and particularly good filling and
covering capacity.
3. Glass sealing – single glazing
With single-glaze windows, putty
must be replaced by suitable
sealers after applying primer and
an intermediate coat. Modern
special sealers such as Window
Repair Sealer 399 can be painted
over easily after allowing them to
cure for about three days.

4. Filling corner connections
Open corner connections must be
well filled. This is not done on
untreated wood but after the inter-
mediate coat before applying the
topcoat. We recommend using
Window Repair Sealer 399.
5. Topcoat
Brillux offers a wide range of
covering products in different gloss
grades for topcoats which meet
both decorative and protective
requirements (also refer to the
table on pages 24 and 25).
6. Glass sealing modern
windows
Sealing glass terminations and
seals is done after finishing all paint
work and allowing the coating to
cure thoroughly, using a perma-
nently elastic silicone sealer such
as Neutral Silicone 386.
Natural wood: renovating with
varnish coatings
A varnish coating build-up is ideal
for maintaining the natural appear-
ance of wood surfaces. Available
coloration ranges from subtle
pigmentation in natural wood
shades to strong, modern colors.
1. Impregnation
After pretreatment the wood is
prepared for the subsequent coating
build-up using Impredur Wood
Impregnating Primer 550. This
deep-penetrating, moisture-regulat-
ing impregnation protects the wood
against blue stain and decay.
2. Primer, intermediate and
topcoat
The primer, intermediate and top-
coat are applied, depending on
requirements and selection, using
Permanent Protection Woodstain
580 or Lacryl Woodstain 235. Spe-
cial bonding agents and pigments
guarantee many years of durable
weather protection. (For a detailed
description of Brillux woodstains,
refer to pages 24 and 25).
3. Glass sealing
Sealing glass terminations and
seals is done after finishing all
varnishing work and allowing the
coating to cure thoroughly using a
permanently elastic silicone sealer
such as Neutral Silicone 386.

Further considerations
Isolating wood components
When it comes to using water-
dilutable coatings and primers, vari-
ous aspects must be carefully con-
sidered. On the one hand, they offer
excellent anti-yellowing stability, on
the other hand color changes may
occur in the case of white and light
color shades on woods such as
pine. The problem is that wood con-
stituents are dissolved by contact
with aqueous products and may
result in stains. Our solution: An iso-
lating alkyd resin primer layer –
Impredur Primer 835 – solves the
problem.
Wood without and with blue stain infestation
Good isolation – uniformly white surface
Bad isolation – wood constituents shine through
Wood protection with
RAL quality seal
In many cases, impregnation is
required in exterior applications as
protection against blue stain and
decay – in the case of untreated
coniferous wood, for example.
Chemical protection should be
effective exactly at the place where
the infestation might occur: deep
inside the wood. For this reason, the
impregnation used must have a
high penetration capacity. This
requirement is perfectly met by
Impredur Wood Impregnating Primer
550: It penetrates deeply into the
wood pores. Its effectiveness has
been documented by the recognized
RAL test institute and certified by
the RAL Quality Seal. Impredur
Wood Impregnating Primer 550 is
perfect for protecting non-soil con-
tact exterior wood not exposed to
static load as well as windows and
exterior doors against decay and
blue stain.

Diffusibility/moisture regulation
Wherever moisture can penetrate
wood via structural joints which
cannot be eliminated, moisture
compensation should be ensured by
proper coating. This applies in par-
ticular to components/structures
without/with limited dimensional
accuracy, such as fences, paneling
and roof undersides. When coating
half-timbering, clear requirements
are defined regarding water vapor
diffusion resistance – an Sd value of
≤ 0.5 m, according to WTA Leaflet
8-7-98/D: Coating of half-timber
walls – wood. This value ensures
largely unobstructed diffusion of
water penetrating via the structure.
Penetration
Penetration depth is a crucial quali-
ty criterion for any impregnation to
successfully provide blue stain and
decay protection. The bonding agent
basis of the product has a major
influence on penetration capacity.
Due to the much smaller molecules
(up to about 10 nm), genuine alkyd
resin solutions penetrate wood
pores much deeper than acrylates,
for example, which are available in
colloidal-dissolved or emulsified
form and have a molecule size
between 100 and 1.000 nm (see
illustration).

Long-term protection without
becoming brittle
Dimensionally accurate structures/
components such as windows and
exterior doors make very specific
demands on topcoats in addition
to providing high diffusibility. A
durable, high-quality protective film
is required which protects against
both weather impact and UV radia-
tion without embrittling or flaking
off. Extremely quick drying and cur-
ing products exhibit a relatively high
tendency towards becoming brittle
and flaking off, thus preventing
effective long-term protection.
Expansion capacity of paint film
Good expansion capacity of the
paint film is a major requirement
of covering coatings for wooden
components without dimensional
accuracy. The reason is that the
components/structures and thus
the coating have to withstand sig-
nificant swelling and shrinking. In
these situations dispersion paints
such as Top Coat 871 provide the
best results due to their bonding
agents.

Take care when using wood-
based panels
Wood-based panels which have
long been used inside are now used
outside too if exposed to direct per-
manent weather impact or conden-
sation exposure as in roof under-
sides. These wood materials carry
various risks such as stain forma-
tion caused by escaping soluble
glue constituents, cracks forming in
the top layer, deformation of the
panels, nutrients for mold or insuffi-
cient edge protection.
Even if the panels are glued using a
weatherproof glue it is still not pos-
sible to provide a general coating
recommendation. Before placing an
order the customer should be
informed about the durability of the
coating and any concerns that may
exist, considering the relevant wood
material, structural/design details,
type of installation and expected
strain.
Maintenance and service
Many home owners don’t realize
what is a matter of fact to experts -
wood coatings don’t last forever.
Depending on exposure, object con-
ditions and coating, maintenance
measures may have to already be
taken after only one or two years. In
some situations maintenance may
only be required after eight to ten
years in order to preserve the value
of a wooden component/structure.
By providing expert information and
entering into responsible mainte-
nance agreements, companies can
earn a good reputation and improve
their future prospects of success,
both at the same time.

Optimum protection for interior
areas
Energy-rich UV radiation has nega-
tive effects not only outside but also
inside. An example is unwanted
color changes which can be seen
on walls when shifting furniture.
With its special UV absorbers for
interior applications Brillux has
developed a technology which lar-
gely prevents the darkening and
yellowing of wood.
The UV absorbing clear varnishes
Lacryl-PU Wood Sealer 262 and
264 are most effective if applied on
previously untreated surfaces so the
original color can be maintained. In
exterior applications standard clear
varnishes as well as colorless var -
nishes just don’t provide sufficient
UV protection due to the additional
weather exposure.
