General Timber Advice

• Timber surfaces must be suitably prepared.
• The moisture content should not exceed 18% prior to coating.
• Resinous deposits should be removed.
• Degrease any exposed bare timber by wiping with a clean, lint free cloth dampened with methylated spirits, frequently changing the face of the cloth.
• Allow the solvent to fully evaporate.
• Abrade sound timber surfaces in the direction of the grain using medium/medium fine grade (P180/P240) pads/abrasive paper (nothing metallic), taking care not to damage or scratch across surfaces.
• Remove dust.
• “Knotting agents” should not be used with Sadolin systems.
• Use Sadolin Woodfillers to make good any minor surface defects. General or all purpose fillers are not suitable.
• We recommend the use of non-ferrous screws, nails and fixings. Exposed ferrous items may corrode and break the coating film over time if not suitably primed/treated prior to decorating.

Preparation – New Timber

• All surfaces must be sound, suitably dry and free from anything that will interfere with the adhesion of the materials to be applied.
• Coat any non treated wood with two liberal coats of Sadolin Wood Preserver paying particular attention to end grains.
• Allow 24 hours before overcoating.
• Where possible, the basecoat, Sadolin Outdoor Varnish, should be applied, all round, prior to fixing.

Previously Coated Timber

• All surfaces must be sound, suitably dry and free from anything that will interfere with the adhesion of the materials to be applied.
• Remove all defective coatings.
• Grey denatured timber should be thoroughly sanded back to clean, bright timber and treated as new.
• Organic growths should be treated with a suitable fungicidal solution and removed.
• Remaining sound surfaces should be cleaned with warm water and mild detergent, rinse thoroughly with clean water and allow to dry.
• Lightly abrade in the direction of the grain, taking care not to break the surface coating.
• Remove dust.
• Localised damage, or severe deterioration of coating requires thorough sanding back to sound substrate and recoated.
• If a coloured base stain is required in order to match the existing factory applied coating, use Sadolin Classic in the most appropriate colour.
• To ensure optimum durability and uniformity of appearance, we recommend the use of an overall coat of Sadolin Classic.

Application

• The final colour and sheen of translucent coatings are dependent on timber species, colour, cut and presence of existing coating amongst other factors.
• We recommend a trial application in an inconspicuous area prior to commencement of work to check for colour accuracy.
• Always intermix (box) packs for colour consistency.
• On new wood: For a clear finish apply 3 coats of Sadolin Outdoor Varnish. For a coloured base apply 1 coat of Sadolin Classic followed by 3 coats of Sadolin Outdoor Varnish.
• On previously coated timber apply 2 coats of Sadolin Outdoor Varnish
• With certain substrates profiles and colours, it may be necessary to apply additional coats to achieve required colour
• Stir well before and during use.
• Use a good quality synthetic bristle brush.
• Apply in a full flowing coat maintaining a wet edge.
• Ensure all surfaces, tops and bottoms of doors, end grains and undersides of cills are coated.
• Avoid overspreading.
