Fiddes Exterior High Build Wood Oil is a versatile wood oil designed to seal and protect exterior wood and joinery from weathering and the effects of UV damage. Perfect for a wide range of exterior wood projects including wooden doors, windows and frames, garden gates and more.

Ensure surfaces to be treated are clean, dry and free from surface contaminates. All surface coatings such as paint, varnish and varnish like wood stains must be removed back to bare wood.

New wood and joinery

  1. Ensure that new wood and joinery has been sanded with a 120-150 grit abrasive
  2. Remove all traces of sanding dust with a slightly damp cloth or vacuum
  3. Treat new wood with a suitable exterior wood preservative
  4. Allow the wood preservative to dry to the specified time before applying this product

Previously oiled wood and joinery

  1. Previously oiled exterior wood and joinery should be lightly sanded
  2. Remove all traces of sanding dust
  3. Any areas affected by fungal growth, algae or moss should be treated with a suitable exterior wood cleaner
  4. Apply a suitable clear or coloured wood preservative If the timber hasn't been treated for a number of years
  5. Allow the wood preservative to dry to the specified time before applying this product

Dense exotic hardwoods that contain a high concentration of natural oils may require a rub down with methylated spirit before oiling to aid penetration of this product.

Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times. Stir thoroughly before and during application.

  1. Apply thinly with a good quality paint brush in the direction of the wood grain
  2. Remove any excess oil immediately with a clean, lint free cloth
  3. Allow 4 to 6 hours to dry before applying a second coat (although overnight drying is recommended)
  4. Sand or denib lightly with a fine 320 grit abrasive
  5. Remove all traces of sanding dust with a vacuum or dry lint free cloth
  6. Apply the second coat in the same way as the first

Regular Cleaning

Wood treated with Fiddes Exterior Wood Oil can be brushed with a stiff broom or brush from time to time to remove surface dirt and debris.

For more stubborn dirt and grime or traces of mould or algae, use a suitable wood cleaner.


If the oil finish is looking tired or is loosing its ability to repel water, a maintenance coat can be easily applied.

  1. Rub down the surface with a stiff brush or lightly sand to remove surface dirt and debris
  2. Treat any areas where biological matter such as mould and algae are present
  3. Apply a thin maintenance coat and wipe off any excess
  4. For wood that hasn't been maintained for an extended period of time, a second thin coat may be required

Good quality product, good, professional and tough finish by Jennifer Riley

This is a quality exterior finish, which I have used both professionally and personally and am happy with the results. It has an easy application and is of such a viscosity that the first few coats sink into the wood well. It gives a nice sheen and smooth finish once several coats have been applied. I regularly recommend this product.

Great wood oil by Mr Eric Bird

This wood oil is easy to apply (don't put coats on too thick) and produces a beautiful sheen finish which provides excellent protection from the elements. Three coats applied on exterior garden furniture items. Can highly recommend EB.

Excellent finish by Roy Mitchell

Used this on cedar cladding. Easy to apply and leave a warm natural finish. Seems to go further than indicated. Worth paying a little more for.

Great by Petra ONeill

Gives water proofing without the varnished look and enhances natural colour rather than changing the colour.

Amazing results from this product by V. Crawford

Our beautiful hardwood door had suffered from heavy weather causing ingrained dirt and we doubted that this could be reversed. However, our carpenter/joiner told us about this product and after carefully and gently sanding down the door he applied this wood oil and the door now looks truly amazing. An added benefit is that the product also gives protection from weather. Cannot recommend too highly.

Not at all disappointed by Christopher Rowe

Wanted a solid, easy to apply durable finish for teak on my yacht. If looks are anything to go by, I'd recommend anyone used to using varnish on exterior wood to try this one. Time will tell, but I have every confidence.

Excellent exterior protection by S. King

Had to apply wood oil to some timber that has the sun on it for a long time. Varnish just pickles too easily. This product will protect the wood for a longer time without peeling issues.

This is a very fine product which keeps my 1920s window cills in good condition by Peter Wylie

I was introduced to Fiddes Exterior oil by our joiner and have used it for the last 5 years on all exterior woodwork including a staircase. We have 1920s oak cills, replacement hard wood cills and a 4 year old oak front door which looks brand new. The secret is being really disciplined about annual treatment. With light sanding a single annual coat is sufficient to keep woodwork in excellent condition.
