and technical performance in opaque coatings. Able to withstand
the harshest conditions, Rubbol systems are low maintenance
resulting in savings in labour costs. Outstanding preparatory
and finishing systems add to their uniqueness, offering superb
extensibility, adhesion and colour retention not matched by

Towards Sustainability
VOC 2010 Compliance
Our innovative products and services will create sustainable
value by systematically reducing the ecological footprint
of the whole-life decorating process and contributing to
more sustainable home, work and leisure environments.
There are still people who prefer to use solvent-borne products and
situations when water-borne products can’t be used, such as low
temperature application. When working with solvent-borne products
you need to be aware of Volatile Organic Compounds (VOC)
emissions and the effect that the solvents contained in coatings
have on the air quality.
‘Step Towards Greener’ recognises that there are no instant
fixes but acknowledges that progress will be made by making
many step-by-step improvements to reach our sustainability goals.
The way we achieve this is also important and we are committed
to ‘Step Towards Greener’ with openness and honesty. Our hope
is that the following pages will demonstrate these commitments.
Water-borne v Solvent-borne
In this context, the development of water-borne products is one
of the most important steps in reducing the environmental impact
of coatings. Using water-borne alternatives to solvent-borne
products can help minimise the environmental impact of the
coating. Water-borne products generally have a lower carbon footprint
due to the replacement of oil-based solvents with water. They are
also better for our air quality.
These environmental benefits come with no loss of quality as
water-borne coatings deliver the same high performance and
durability as their solvent-borne alternatives. Proof is provided by
the range of water-borne Cetol and Rubbol products that Sikkens
has already developed. These include Cetol BL21 plus and Cetol BL31,
Cetol BL Primer and Cetol BL Opaque, Cetol BL Decor, Cetol
BL Unitop, Rubbol BL Primer and Rubbol BL Satura.
4
VOCs are emitted from many sources including fuels, numerous
industrial operations and household products such as cleaning agents,
cosmetics, aerosols, stains and varnishes. In the presence of sunlight
they can react with vehicle exhausts to form low level ozone which
can lead to smog.
The VOC 2010 legislation introduces new, stricter limits on the
maximum amount of VOCs that can be contained in decorative
paints, stains and varnishes. Products are divided into categories
and within each category different limits apply to solvent and
water-borne products.
From 1st January 2010 non-compliant products can no longer be
manufactured but they can still legally be sold until 1st January
2011. Painters and decorators are not affected by any legal
deadlines and can use up all of their non-compliant product stocks
beyond 2011.
Compliant Products with the ‘plus’
Extensive research by ICI Paints AkzoNobel, employing the very latest
technology, is being used to ensure that Cetol and Rubbol
products continue to be available in new compliant formulations.
This new generation of coatings will have the highest performance
characteristics and be in every way the equivalent of the noncompliant formulations.
For ease of indentification
they will have the word ‘plus’
added to their product name.

Cetol Design Concept
The world of wood protection is evolving, particularly with the increasing
range of tonal colours and innovative effects available, together with the
rediscovery of the visual appeal of natural materials. In response to this,
Sikkens has developed the Cetol Design Concept consisting of the Classic
Collection and the Style Collection. To help you plan your decorative
schemes, the colour cards for these collections uniquely show each colour
in two finishes - translucent and opaque.
Classic Collection
The Cetol Design Classic Collection is a truly inspirational selection of colours.
This functional and aesthetic range of woodstains gives professional users the
opportunity to be highly creative and to bring a modern look and feel to
projects. See colour swatch on next page.
4041 Colour Concept
Introduced for Rubbol exterior opaque coatings, the collection comprises
some 1624 colours delivering extensive choice. A swatch device also makes
selection of colours quick and easy.
Colour Guide
Style Collection
The Cetol Design Style Range comprises authentic, natural, modern, very strong
and primary colours. Most can be used on both interior and exterior surfaces.

The most critical aspect of protecting
timber is the preparation of the surface
prior to the application of coatings and
the key areas are as follows:
Cut Out Decay
To ensure that all infested timber is removed, cut out up to an inch (2.5 cm)
into sound timber.
General Cleaning
Thorough cleaning of the surface is required to remove most of the contaminants
which can impair the absorption, adhesion and subsequent performance of
coating systems. A solution of household detergent in warm water and a
stiff, non metallic bristle brush is ideal for removing oil, dust, dirt or grease.
Thoroughly rinse off any residues and allow the surface to dry fully.
Fungicidal Wash
Treat growths with a fungicidal wash or bleach solution and allow 15-20
minutes to work. Loosen dead spores using a stiff, non-metallic bristle brush,
rinse with clean water to remove all residues and allow the surface to dry fully.
Heavier deposits may need multiple applications.
Removal of Old Coatings
Chemical strippers are the most practical way to remove unsound coatings.
Do not remove sound coatings, particularly opaque finishes for the sake of
it but do test them to ensure they are truly sound. Woodstains must be
removed if a lighter shade of woodstain is required.
Base stains on new joinery provide approximately 3 months protection and
their condition should be assessed before top coats are applied.
Sanding
To prevent decay occurring again where damaged timber has been removed
from a rotten area, a preservative such as Cuprinol Trade Wood Preserver
Clear (BP)* should be applied to saturation. Timber used to splice in for
repair, should be either of a durable species or pre-treated with preservative.
Degreasing
Surface contaminations of natural timber such as tannins, gums and oils from
hardwood and resins from softwood should be removed with a cloth dampened
in a suitable solvent (NOT white spirit or turps).
Knots
Play a hot air gun over live knots to draw out as much resin as possible, scrape
off the resin and degrease as above. Remove dead knots and fill with a
suitable woodfiller.
Substrate
Preparation
Bare timber exposed to sunlight for more than 3 weeks will require the removal
of the surface back to bright timber. Mechanical sanding is the only really
effective method. Abrasive papers should be used - DO NOT use wire brushes
or steel wool.
Preservative Treatment
* Cuprinol Trade Wood Preserver Clear(BP) contains propiconazole and IPBC.
Use biocides safely. Always read the label and product information before use.

Fillers
Voids or areas of damage in timber should be filled prior to coating.
Arrises
To ensure even, adequate coating to vulnerable edges, all cills should be rounded
to approx. 3mm radius (‘pencil round’) and all other sections to at least 1-2
mm radius.
Bad
Good
Silicone Contamination
To avoid the problems of silicone contamination - cissing/cratering/fish-eyeing
- a specialist silicone remover or ‘digester’ must be used. Multiple applications
may be necessary.
Salt Efflorescence
Mortar/Iron/Water Staining
Best treated with a wood bleach (active ingredient oxalic acid). Remove all
surface coating prior to application. Where iron staining has occurred, remove
the cause of the discolouration.
Occurs in plywood when atmospheric moisture causes the salts in the glueline
to migrate to the surface in the form of white crystalline powder. The strength
and integrity of the plywood is unaffected. Normally rainwater washes the
salts away but on sheltered surfaces, such as soffits, they remain as a bloom
on the surface. Where efflorescence is present, remove fluffy efflorescence
deposits by rubbing with dry Hessian sacking at frequent intervals. Check
salts do not return within 48 hours, before proceeding. Remove heavy deposits
by careful* manual abrasions taking care not to damage the surface finish
of the substrate. The surface can then be re-treated. The condition may recur
and repeated washing may be required. Eventually the efflorescence will cease.
*When rubbing down and/or dusting off wear a suitable face mask
to avoid the inhalation of dust.
Nails/Screws
Non-ferrous fixings are recommended. Where the use of steel/iron fixings is
unavoidable, they should be driven home and the resultant holes filled with
a suitable filler.
Moisture Content
Timber to be coated should have a moisture content close to what it will be
in service. Below 14% for interior timber and between 15-18% for exterior
timber is recommended.

The methods, techniques and conditions
of application are also critical to the
successful use of coatings.
The key areas are:
Coat Surfaces All Round
Any area which could allow moisture ingress should be adequately coated
to form a ‘skin’ or ‘envelope’. Tops and bottoms of doors are particularly at
risk. The weatherbar should also be fully coated and sealed before fixing and
the joint capped off with a suitable elastomeric sealant. The back of cladding
should also be treated to avoid coating failure.
Fully Treat End Grains
Moisture is particularly absorbed into the end grain of timber. For this reason,
cills especially above ground floor level should receive adequate coating to
ensure optimum performance.
Apply Sufficient Coating
Sikkens exterior woodstains are designed to be gradually eroded by the
weather, which makes them so easy to maintain. However, sufficient coating
must be applied to ensure it achieves its expected performance. Brush application
rarely achieves a wet film thickness of more than 60 micrometres for stains
and 100 micrometres for opaques.
Stir Product Thoroughly
Drying Times
A coating may feel dry but it is not necessarily dry enough to overcoat. Waterborne coatings must lose organic solvent as well as water, and solvent-borne
coatings must ‘cure’, a process which usually takes 12-18 hours. Adverse
drying conditions (e.g. cold, damp, little ventilation) will extend and can even
double drying times. While water-borne coatings can often be fully dry in less
than 4 hours, solvent-borne-coatings can take up to 24 hours even in good
drying conditions.
Patch Prime/Bring Forward
When applying maintenance coats, bare timber surfaces should be given an
appropriate first coat, whether it is a base stain or a primer. For woodstains,
as well as the base stain, it is often necessary to ‘bring forward’ the base stained
section with sufficient coats to restore the same shade and build as the
surroundings. The only alternative is to strip the whole section back to bare
timber and re-coat.
Weather Conditions
It is common sense NOT to apply coatings in the rain. Equally, if the coating is
not dry before rainfall, the finish can be damaged or even washed off. Moreover,
when rain is imminent the humidity level is increased, which may also create
drying problems. A general rule of thumb for temperature is that water-borne
and solvent-borne coatings should not be applied or allowed to dry outside the
range 8°C to 25°C and 5°C to 30°C ranges respectively.
Treatment Sequence
Generally the treatment sequence is:
1. Surface preparation
2. Preservative pre-treatment
3. Base stain
4. Finishing coats
5. Maintenance
Maintenance Sequence
If the original woodstain has been correctly applied then the only
maintenance steps required are those in bold type. However, if this
is not the case, or if the surfaces have been left too long before being
maintained, additional steps shown in italic type are necessary.
To avoid possible problems be consistent with the use of either a complete
water-borne or solvent-borne system.
Remove and treat algae/mould
Brushes
Clean other sound surfaces
Good quality, long haired bristle brushes are recommended for solvent-borne
coatings and synthetic bristle brushes for water-borne coatings. Good quality
synthetic brushes can be successfully used for both.
Remove resin and degrease
Apply one or two coats of the
appropriate Sikkens woodstain
Stir the product thoroughly before and regularly during application.
Use a broad bladed stirrer which reaches the bottom of the container.
