Timber surfaces to be treated must be suitably prepared, clean, sound and dry. The moisture content should not exceed 18% prior to coating.

Bare and New Timber

1. Resinous deposits should be removed with a scraper
2. Degrease any exposed bare timber by wiping with a lint-free cloth dampened with methylated spirits
3. Timber exposed to weather for 4 weeks or longer, or any loose, grey or de-natured timber, must be thoroughly sanded back to a clean, sound surface
4. Some tropical hardwoods such as Iroko, Idigbo and Teak should be scrubbed with cellulose thinners prior to application
5. Organic growths must be removed and infected surfaces should be treated with a suitable mould and mildew cleaner
6. Remaining sound surfaces should be cleaned using warm water and a mild detergent, then rinsed thoroughly with clean water
7. Knotting agents should not be used with Sadolin translucent systems
8. Fill any holes or imperfections in the timber with Sadolin Wood Filler, or for larger areas, Sadolin Stainable Wood Filler
9. Only use non-ferrous screws, nails and fixings
10. Any non-preservative-treated softwood timber should be treated with two liberal coats of Sadolin Quick Drying Wood Preserver, paying particular attention to end grains and allowing 24 hours drying time between coats, prior to over-coating with Sadolin Outdoor Varnish

Previously Coated Timber

1. Any previous paint coating and all defective coatings should be completely removed and sanded back to clean, bright timber, then treat as 'New Timber'
2. Take special precautions during the surface preparation of pre-1960s painted surfaces as they may contain harmful lead

Glazing

1. The backs of new glazing beads, end grains and rebates should be brought to a finish in full with Sadolin Outdoor Varnish prior to fixing
2. Joinery to be coated with Sadolin woodstain systems should be glazed using a suitable sealant
3. The use of linseed oil putty or modified, non-setting compounds are not recommended in conjunction with Sadolin systems
4. To confirm compatibility, please consult the manufacturer of the relevant glazing material
5. Silicone glazing materials should only be applied upon completion of the finishing coats

Please Note: Sadolin Outdoor Varnish can be used in conjunction with 1 or more base stain coats of Sadolin Classic Wood Protection, where a stain colour is desired, followed with 2 full coats of Outdoor Varnish.

Always do a small test area to before beginning any project to assess consistency and compatibility of the finish. Follow the manufacturer's instructions on the tin at all times.

Do not apply if there is a risk of rain, or when air / substrate temperatures are below 8°C; or above 25°C, or if 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 product is thoroughly stirred before and during application, otherwise sheen variations may be experienced. This product is supplied ready for use. Do not thin.

1. Apply in a full flowing coat, ensuring all surfaces and end grains are fully coated
2. For best results, use a good quality, long-haired, soft bristle brush
3. Where possible, Sadolin Outdoor Varnish should be applied all round prior to fixing
4. Pay special attention to end grain, tops and bottoms of doors, and undersides of sills
5. Apply 2 or 3 coats of Sadolin Outdoor Varnish, dependent on the requirements of your project
6. Allow 16-24 hours drying time between coats

Cleaning Equipment

Clean brushes and equipment with a proprietary brush cleaner immediately after use. If spilled, the varnish should be removed immediately while still wet, using clean white spirit.

Sheen level is the amount a product reflects light. Matt doesn't reflect very much light and Satin has a mid-sheen.

This product does not contain any pigments to colour the timber. It is a clear varnish which puts a film over the surface of the wood to seal it. Perhaps consider Sadolin Classic Wood Protection as an alternative.
