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.

Need extra hard-wearing wood stain? We talk about Sadolin's fabulous product in our special wood stain blog post.


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.

An excellent and highly durable product for treating exterior timber.
Great price compared to the competition. Delivered on time as always. I'll be back to Wood Finishes Direct as my first choice online supplier the next time I need anything.

Nice oil-based protection
So many woodstains are water-based these days which is no good when you live at the top of a valley and the wind and rain buffets exposed hardwood in winter. The previous owners used a water-based product (expensive too) and we are rectifying the consequences. I heartily recommend this. Hopefully it'll last a couple of years though we will redo every year
Anthony Metcalfe
 2.5L, Teak
Pretty good but not quite as long lasting as I would like, better than anything else I have found, I have used it since 2000
Easy to use with brush or spray Preserves solid wood well but does not seem so good on engineered / veneered exterior doors that re getting more common. In my opinion better than ronseal which does not seem to do as it says on the can
Richard Banks
 1L, Mahogany
Sadolin is just about the best of the wood stains
I have been using it for about 30 years, it penetrates the wood, remains stable, does not peel or chip, repels water, colour stays static, covers well, what more is there to want?
David Carew
 1L, Ebony
Just simply, the best.
I have used wood stains for over fifty years; I have yet to find one that gives the same result and lasts for many years.
Simon Woods
 2.5L, Redwood
Natural and vibrant colour, long lasting and easy to use
This is the second tin of Sadolin Classic that I've bought. I am impressed with the consistency, colour and longevity of the woodstain protector. As with all of these products, make sure you read the instructions before using so you get the best out of the product (i.e. prep work, application and cleaning). This one is applied after the 'Sadolin Classic' application.
Ken Senior
 1L, Natural
Superb finish excellent coverage.
Using two base coats of Natural Classic as recommended followed by two top coats of Natural Extra sanding using 240 grt in between each coat and washing off with meths I was able to obtain an excellent finish on our new solid oak door.
Ms Owen
 2.5L, Redwood
Excellent product easy to apply and gives a lovely finish
Very pleased with this product was easy to apply and gave a good coverage and looks as if it will resist peeling etc
Angus McDonald
 2.5L, Mahogany
Went on OK but time will tell
The staff were very helpful as I was not sure of the products available
Keith Young
 1L, Teak
Easy application and excellent finish.
The product is very easy to apply. It spreads well when brushed on and I didn't get any 'runs'. The finish is a great-looking natural wood effect which brings out the grain of the wood and provides superb protection to the wood both inside and outside.
