Sadolin Superdec Opaque Wood Protection

Wooden surfaces to be treated with Sadolin Superdec must be suitably prepared, clean, dry and free from all traces of surface dust and debris. The moisture content should not exceed 18% prior to coating.

New or Bare Wood

• Resinous deposits on bare timber, especially new wood, should be removed by wiping with a lint-free cloth dampened with methylated spirits
• Knotting agents should not be used in conjunction with Sadolin Opaque Wood Protection
• Use an appropriate wood filler for making good any minor surface defects, imperfections or open joints
• Some general or 'All Purpose' fillers may not be suitable
• Only use non-ferrous fixings, screws and nails
• Where there is a risk of extractive discolouration, especially when using white or pale colours on resinous / knotty softwoods and coloured hardwoods, an initial coat of a suitable blocking primer is recommended in order to minimise the risk of this type of discolouration
• Timber that has been exposed for 4 weeks or more will require sanding back to a clean, sound surface
• If required, pre-treat wood with Sadolin Quick Drying Wood Preserver before applying Sadolin Superdec
• Lightly abrade (sand), in the direction of the grain to a smooth surface, using a medium grade abrasive paper
• Do not break through the existing surface coating
• Thoroughly remove all wood dust
• Where there is localised damage, or deterioration has occurred as a result of exposure of the factory coating for longer than 3 months, affected areas should be thoroughly sanded back to a sound substrate and recoated

Previously Painted or Varnished Wood

• Previously painted and varnished surfaces in good condition should only require a light sanding to aid with adhesion
• Stained surfaces in good condition should only need to be washed down with warm water and detergent, allowing to dry before application
• For surfaces in poor condition, remove any loose, flaking material with a scraper or abrasive paper, sanding in the direction of the grain
• Remove any weathered timber, and sand the sound coating with abrasive paper to provide an adequate key
• Strip any surfaces in poor condition bare and treat as new wood
• Where there is localised damage, or deterioration has occurred as a result of exposure of the factory coating for longer than 3 months, affected areas should be thoroughly sanded back to a sound substrate and re-coated

Glazing

• The backs of new glazing beads, end grains and rebates should be brought to a finish with Superdec Opaque Wood Protection prior to fixing
• Joinery to be coated with Sadolin Superdec should be glazed using a suitable sealant
• The use of linseed oil putty or modified, non-setting compounds are not recommended in conjunction with our wood protection systems
• To confirm compatibility, please consult the manufacturer of the relevant glazing material
• Silicone glazing materials should only be applied upon completion of the finishing coats

Always do a small test area before starting any project to assess product suitability, adhesion and finish. Follow the manufacturer's instructions on the tin at all times. This product is not suitable for use on wooden decking or floors, copper, polished concrete or concrete floors. For decking view our full range of Decking Treatments.

Do not apply if there is a risk of rain, or when air / substrate temperatures are below 8°C or above 25°C or the relative humidity is above 80% during application or drying periods. Protect from frost and rain until dry. Failure to meet these requirements may adversely affect the drying, visual quality and durability of the finish.

Ensure Sadolin Superdec Opaque Wood Protection is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced. Sadolin Superdec is supplied ready for use. Do not thin.

1. Apply Sadolin Superdec in a full flowing coat, ensuring all surfaces and end grains are fully coated
2. For best results, use a good quality synthetic fibre brush specifically designed for use with waterborne products
3. Pay special attention to end grain, tops and bottoms of doors, and undersides of window sills
4. Allow 4 hours to dry

Maintenance

A lightening in colour, reduction in sheen and a loss of water-repellency is an indication that maintenance is required. For general maintenance, lightly abrade in the direction of the wood grain and clean using warm water and a mild detergent, then rinse thoroughly with clean water. Once dry, a fresh coat of Sadolin Superdec Opaque Wood Protection can be applied.

If the finish is badly flaking or peeling, to the point where the bare wood is showing through or has started to grey, please follow the full Preparation and Application instructions above.

Absolutely, it is such a versitile product for use on a range of substrates. We would recommend a lighter colour on this surface due to the heat that a darker shade can attract.

This is generally not needed when using Sadolin Superdec unless you are using white or pale colours on resinous / knotty softwoods or coloured hardwoods. If using these, an initial coat of a suitable blocking primer is recommended to minimise the risk of discolouration from resins in timbers.

As a super flexible product, this paint works fantastically outside but it wouldn't be durable enough to be used inside under foot.

Yes, we would recommend a lighter colour on this surface due to the heat that a darker shade can attract. Give the surface a key and a clean up before use.

You certainly can. Be careful to ensure that the substrate is clean and sound with no peeling or flaking and apply two- three coats of Sadolin Superdec, depending on colour selection.

The green is most likely Algae, if so, that needs to be removed with an algae remover such as Ronseal Decking Cleaner and Reviver otherwise it may stop paint from adhering.

As standard, the Sadolin Superdec colour are all a satin finish (mid sheen) unless you specifically select the White/ Black Gloss option.

Absolutely, the Sadolin Superdec is a very flexible external paint, meaning that it resists peeling and flaking as the timber naturally expands and contracts.

Sadolin do not recommend spray application due to the thickness of the paint. Instead consider a good quality brush such as ProDec Premier Synthetic Brush or Marshall Velour Roller depending on what you are applying it to.
