Towards Sustainability

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.

‘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-borneIn 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.

VOC 2010 Compliance

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.

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 non-compliant formulations.

For ease of indentification they will have the word ‘plus’ added to their product name.

Guide

Cetol Design ConceptThe 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 CollectionThe 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.

Style CollectionThe Cetol Design Style Range comprises authentic, natural, modern, very strong and primary colours. Most can be used on both interior and exterior surfaces.

4041 Colour ConceptIntroduced 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.

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:

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

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.

Cut Out Decay

To ensure that all infested timber is removed, cut out up to an inch (2.5 cm) into sound timber.

Preservative Treatment

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.

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.

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.

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.

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.

Fillers

Voids or areas of damage in timber should be filled prior to coating.

Salt Efflorescence

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.

Application and

Maintenance Systems

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

Stir the product thoroughly before and regularly during application. Use a broad bladed stirrer which reaches the bottom of the container.

Water-borne or Solvent-borne Compatibility

To avoid possible problems be consistent with the use of either a complete water-borne or solvent-borne system.

Brushes

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.

34 35

Drying Times

A coating may feel dry but it is not necessarily dry enough to overcoat. Water-borne 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 preparation2. Preservative pre-treatment3. Base stain4. Finishing coats5. 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.
