  • Overview

Perfect for any exterior wooden surface, such as doors and garden furniture, Fiddes exterior wood oil provides an effective barrier against the damaging effects of weathering and bleaching from the sun.

Made with a blend of natural resins and oils, this high grade wood oil produces a transparent satin finish that has exceptional durability and resistance. Quick and easy to apply, exterior wood oil produces a clear, quick drying water repellent and weather resistant finish that will not flake or peel.

A popular choice with woodworkers, joinery professionals and DIY enthusiasts alike, Fiddes exterior wood oil provides a versatile solution for all of your exterior wood preservative needs. Although more expensive than some alternative products, just 3 coats are all that is required to offer maximum protection instead of the 4-5 coats of some alternative products.

Fiddes exterior wood oil is occasionally decanted into smaller Manns label tins to allow us to offer a larger product range and avoid stock shortages.


For the best results, treat exterior wooden surfaces with Barrettine Wood Preservative prior to applying Fiddes Exterior Wood Oil.

For the best results, surfaces should be clean, dry and free from any previous wood finishes, this can normally be achieved by a light sanding with a 120 grit sanding paper. All residual wood dust should be removed before application of the wood oil.

Any fungal growth, dirt or moss also needs to be removed prior to the application of the exterior wood oil.


Exterior wood preservatives should always be applied in dry conditions, it's also advisable to test the wood oils on a small test area prior to application. Fiddes exterior wood oil is formulated for direct application and does not require any thinning or coats of primer.

For the best results, the exterior wood oil should be thoroughly stirred before and during use. The exterior wood oil should be applied thinly with a good quality paint brush in the direction of the grain. Any excess wood oil should be immediately removed with a cloth.

Drying time is around 4 to 6 hours (most oils take 12-48 hours) although overnight drying is better. Before application of the second coat, sand lightly with a fine 320 grade sand paper or sanding disk again being careful to remove any dust that this may create. The second coat should be applied as the first, thinly and in the direction of the grain with a further 4 to 6 hours drying time.

Equipment Cleaning

Brushes and other applicators used to apply this product should be cleaned with white spirit immediately after use.


Tins of Fiddes exterior wood oil, new and used, should be tightly closed and stored in a cool well ventilated area.


Fiddes wood oil as with many other solvent based wood preservatives and oils is flammable so should be kept away from children, naked flames, cigarettes and other sources of ignition.

Used cloths can self ignite if left uncleaned after use. It is important that any used cloths are thoroughly washed in warm soapy water and thoroughly rinsed before they are disposed or stored in an airtight container.

It is recommended that gloves and eye protection are worn when applying exterior wood oil or other solvent based wood finishing products. In the event of contact with the eyes, they should be immediately rinsed with plenty of water before seeking urgent medical advice.

This Fiddes clear wood oil should be kept away from children, food, drinks and any other food related items.

Drying Time

Leave to dry 4 to 6 hours or preferably overnight between coats. Longer drying periods may occur during application in damp or humid conditions.

Easy to use and rich colour
Really easy to apply and follow instructions by wiping off excess with the cloth as otherwise too glossy
Paul Beck
Very good finish, more a varnish than an oil
Applied over Barrettine wood preserver base coat. Goes on very well with a brush.Definitely wait overnight to recoat. Used the clear on Sapele gates, which gave a very even high sheen finish, but more of a varnish than an oil. Only recently applied so don't know about how it will last, but have had quite a few compliments so far.

Easy to use. Excellent finish - this has transformed my hardwood summer house.
Easy to apply each coat, and with an excellent finish which enhances the wood.This looks as if it's going to be a durable product.

The perfect finish for external Oak
After a wee bit of research I finally opted for Fiddes Exterior High Build Wood Oil, and I am very satisfied that I made the right choice for my custom built Oak table. It was also very easy to apply and also promptly delivered by WFD. I would highly recommend this product.

A very good product
Bought to maintain a solid British oak door and frame. This had had 3 coats of Fiddes Oil when made. The maker and installer recommended this product and I have found it to be an excellent product
Ian Leckenby
Seems to be an excellent product.
Just had an oak garden room installed. The Wood Oil certainly puts a very pleasing finish to the untreated internal surfaces of the large oak beams. The outside had already been treated, but a couple of additional coats in spring should help preserve the finish perfectly.
Ingrid Easterbrook
Easy to brush on high build wood oil
Used on our oak front door, gives a very natural wood finish over the Barratine wood preservative. Cannot comment on how long lasting as we have only just done it. User friendly website and helpful staff at the end of the phone. Recommended
Thomas Laurie
Effective & Easy to use.
This product leaves the wood looking rich and nourished. My garden shed is 4 years old and was badly faded. The first coat soaked into the grain immediately. The second coat left the timber looking like new wood.
Kelvin Storer

A great product and finish for my outside bench .
Luke Jeffs

Stuart Allston
Great product, easy to apply and has a superb finish. rapid drying time.
I have used this product many times in different situations from Kitchen work surfaces to floors to complete items of furnture. it so easy and quick to apply and drys much quicker than other oils of its type. The overall finish it gives the wood is fantastic and to maintain is so simple. Recommend everyone in the trade to try it.

Used for several years
By far the nicest to use and most effective oil varnish I have used
Juliet Snuggs
Excellent - beautiful finish on my front door!
We bought this for our front door and it looks amazing! we will certainly buy more for our new internal oak doors - really brings out the colour and texture of the wood - beautiful!
David Wood
Good no problems
Best thing I can say is that i have been back for more and I have no doubt I will be back again in another couple of years to refresh the oak lintels and framing again
Valerie Tate
Does what is says,
We have used this product for 6 years, it keeps our oak doors and windows looking great. It goes a long way and protects the wood.
William Wright
Used it before and will use again. Excellent on my external red cedar.
Used it before and will use again. Excellent on my external red cedar. Easy to apply. Has protected it well for 2 years against string winds and weather at times. Neighbours admire it.
David Seabrook
Does what it says on the tin!
Used on summer house roof (cedar) 2 weeks ago. Applies 1 coat on top of 2 coats Barrettine Premier Wood Preservative. Looks good at the moment but I'll be interested to see what state it's in 12-24 months from now. That would be the time to provide a realistic review.
