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, window 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


Exterior wood 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 exterior wood cleaner.

Renovation and Repair

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

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.

Excellent product and easy to apply by Peter Leigh

I have had exoeriences in the past where a company has supplied the sma eproduct but it never went off and ruined a project that I was working on. This product was first class and was easy to apply and gave me the finish I was looking for and in the timescale that was on the tin.

Very good finish, more a varnish than an oil by Paul Beck

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.
