  Read reviews (43)

Sadolin Extra is a durable woodstain suitable for all softwood and hardwood joinery including doors and windows. Its flexible nature and water repellancy provide long lasting protection.

For optimum durability on new wood, the use of Sadolin Classic Wood Protection as a base coat is recommended, particularly when treating hardwoods.

Touch dry within 5 hours, with a re-coat time of 12-24 hours. Not suitable for high-traffic areas such as decking.

  • Overview


Perfect for a wide range of exterior wood projects including windows, doors and more. Sadolin Extra Durable Woodstain dries to a semi-gloss finish.

Note: This product is not suitable for use on decking.

Dense exotic hard woods tend to contain a lot of natural oil. Hardwoods such as Teak, Ipe, Meranti and Balau must be thoroughly de-greased with methylated spirits prior to applying Sadolin Extra Durable Woodstain.

Timber surfaces must be clean, dry and structurally sound. All traces of surface dirt and debris including mould, algae and fungi must be removed prior to application with a suitable product such as Barrettine Fungicidal Wash (Multicide). The moisture content of the wood should not exceed 18% prior to coating. Resinous deposits should be removed. Degrease any exposed bare timber surface by wiping with a cloth dampened with methylated spirits.

Knotting agents should not be used with Sadolin translucent woodstain systems.

Fillers specifically designed for use with exterior timber should be used for making good any minor surface defects, imperfections and open joints etc.

Only use non - ferrous screws, nails and fixings

New Timber

Timber that hasn't been pre-treated with a wood preservative should be treated with two liberal coats of clear Sadolin Quick Drying Wood Preserver paying particular attention to end grains. Allow 24 hours drying time between coats and before overcoating with 1 full coat of Sadolin Classic Wood Protection. Where possible, the wood preservative and base coat should be applied to all parts of the timber prior to fixing.


Do not apply if there is a risk of rain, or when air / substrate temperatures are below 8℃ or above 25℃, 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 and colour variations may be experienced. Sadolin Extra is supplied ready for use. Do not thin.

Sadolin Extra Durable should be applied in a full flowing coat ensuring all surfaces and end grains are fully coated. For best results use a good quality brush. Pay special attention to end grain, tops and bottoms of doors, and undersides of window sills. Following surface preparation and application of Sadolin Classic in accordance with the manufacturers recommendations (refer to the Sadolin Classic product information sheet for additional information). Finish with two full coats of Sadolin Extra Durable Woodstain allowing a minimum of 16-24 hours drying between coats.


The need for maintenance is indicated by a lightening in colour, reduction in sheen as the coating erodes, and a loss of water repellence. All defective coatings should be completely removed / stripped. Any grey denatured exposed timber surfaces must be thoroughly sanded back to clean, bright timber. Organic growths must be removed and infected surfaces should be treated with a Fungicidal Wash. Remaining sound surfaces should be cleaned using a warm water and mild detergent and rinsed thoroughly with clean water. Bare timber should be patch primed with one or more coats of Sadolin Classic in the appropriate colour to match existing colour. On weathered / eroded surfaces apply a further coat of Sadolin Classic overall and allow to dry. Finish with 1 or 2 coats of Sadolin Extra Durable as required.

Thinning and Cleaning

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


Ensure the tin is stored upright and secure at all times. Do not store where temperatures are likely to drop below 5℃ or exceed 40℃.


Q. Can Sadolin Extra Durable Woodstain be used on decking?

A. Sadolin recommend that Extra Durable Woodstain is not used on decking due to its high surface build and shiny finish. This product is likely to wear quicker than a dedicated decking stain or oil and could pose a slip hazard.

Drying Time

  • Touch dry : 4-6 hours.
  • Recoatable : 12-24 hours.
Note: Drying times are dependent upon absorption of timber and drying conditions. drying times will be extended in low temperatures and / or high humidity conditions.

 2.5L, Light Oak
Fantastic natural colour match and great overage
We were worried about applying any kind of stain to our new oak extension however this Sadolin light oak stain gave a near perfect natural colour match and finish. We got 2 coats on without using even half the tin. Will definitely use this product in the future if the wood requires it

 2.5L, Burma Teak
Best weather coat for TGV boarding as it will move with the seasons
This top coat will move with the wood with out cracking. The old boards lasted twenty years with the same treatment. This time they will last longer with attention paid to end grain treatment and sharp corner rounding.
