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.

Silver fir

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

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).

22

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.

Page 23: Perfect design and lasting

23

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.
