The best Larch oils, compared.
Top pick: Osmo 009 larch oil 0.75 litre Best value: Bondex larch oil 3 litres – Lowest price per litre among tins with a real review count, about £10.12 per litre at about £30.36 for 3.0 litres. Updated October 2026.
Larch oil is an exterior oil for larch decking, garden furniture and similar outdoor timber. In the UK you buy it when grey boards or chairs need a warm tone and water beading, rather than a thick varnish film. A suitable tin names outdoor timber, a volume for thin coats, and a pigment or a stated finish. Natural on these oils means a warm tan, not a colourless coat. Species, position and the limit of an oil stay the same whichever tin you open. Heartwood durability is a property of the timber, and an oil does not raise it. These listings are weather and appearance finishes, not an authorised wood preservative. New resinous boards should wait. Grooved decking uses more oil than a smooth board. Oily cloths can self-heat, so dry them flat outdoors or soak them in a lidded metal container. Volume, pigment and horizontal use are in the [larch oil buying guide](/hub/paints-and-varnishes/larch-oil/sub/larch-oil-buying-guide). Coat thickness and cloth safety are in [how to apply larch oil](/hub/paints-and-varnishes/larch-oil/sub/larch-oil-how-to-apply). A drying oil for indoor timber is compared under [boiled linseed oil](/hub/paints-and-varnishes/boiled-linseed-oil).

Question 1 of 2
What are you oiling?
Osmo Color Wood Oil (Natural Tinted 009) 0.750 litre is £23.82, with 4.7 from 140 ratings and part number 11500020. The bullets are the same pigmented, microporous, water-and-dirt exterior claims as the 2.5 litre tin, aimed at garden furniture and decking. About £31.76 per litre, it is not a cheaper formula than the large tin. The written reviews are German and Italian, not marked as United Kingdom, and those comments dwell on a brown or ochre tint and on coverage below an 18 square metre figure one reviewer read on the tin. Use it as the small tin of Osmo 009 when you want a trial or a piece of furniture, and read the star line as the UK aggregate rather than as British review prose.
Pros
Cons
Best for: A first patch or garden furniture when you want Osmo 009 and do not need 2.5 litres.
Less suitable: A large grooved deck, where this tin is the expensive way to buy the same oil.
Specifications
Common questions
Is the 0.75 litre tin the same oil as the 2.5 litre Osmo 009?
The colour field is 009 natural-tinted larch oil and the part number is 11500020. The bullets match the 2.5 litre listing. The listing does not print the word identical.
Does the listing answer the UV question?
The listing asks whether it protects against UV rays and does not answer. The bullets do not use the words UV.
Are the written reviews from the United Kingdom?
No review block on that listing is marked United Kingdom. The 4.7 from 140 is the amazon.co.uk star line. The written comments are from Germany and Italy.
Osmo Natural Coloured Larch Oil (009) in 2.5 litres is £72.31 on this amazon.co.uk scrape, with 4.6 from 487 ratings, part number 11500021. The bullets describe a pigmented, microporous exterior finish for garden furniture and decking that is water and dirt resistant and is not supposed to crack, peel or flake. UK reviews praise porch and deck coverage and also say the natural shade is tan or orange and can hide pale grain. One UK review says the tin claims about 60 square metres. The listed weight of 750 g and the 1 cm dimensions are catalogue noise. About £28.92 per litre, it is the tin with the most ratings in this set, and it is a poor match if you wanted a colourless oil.
Pros
Cons
Best for: A larch deck or a run of outdoor furniture when you want Osmo 009 in the 2.5 litre tin and you have already checked the tint on an offcut.
Less suitable: Anyone who needs a clear, colourless oil, or who only has a chair to test.
Specifications
Common questions
Is this Osmo tin clear?
The listing calls it a pigmented finish and the colour field is a natural larch tint. A UK review says natural is not clear and has some tan colour. Another UK review describes the result as orange.
Can it be used on garden furniture?
The listing bullet says it is especially recommended for garden furniture and decking. There is no separate answer under that question on the listing.
Does the listing say it is safe for animals?
The listing asks whether it is safe for animals and does not answer. Do not treat silence as a yes. Keep pets off the wet oil.
Bondex Larches Oil, part 388158, is £30.36 for the 3.0 litre size named in the title, with 4.6 from 399 ratings. That is about £10.12 per litre, the low figure in this set. The listing describes a matte, open-pored oil with a water-beading effect, weather and UV protection in the bullet wording, and cover for decking, garden furniture, privacy elements and pressure-treated wood, at 22 m² per litre. A second field that says 30 litres contradicts the title. Reviews on the page are in German and praise easy brushing and a refreshed larch tone, and they also say you must stir, wipe excess or it stays tacky, and that real coverage on bare wood is lower than 22 m² per litre. It is the price pick here, not an Osmo 009 equivalent with a UK application sheet on the listing.
Pros
Cons
Best for: A large area of outdoor wood when the priority is litres per pound and you accept a matte Bondex oil rather than Osmo 009.
Less suitable: A buyer who needs Osmo’s part number 009, or who trusts a 30 litre reading of the specification table.
Specifications
Common questions
Is the tin 3 litres or 30 litres?
The title says 3.0 litres and the unit count is 3000 millilitres. A liquid-volume field says 30 litres. Use 3.0 litres.
What coverage does the listing state?
The specification says 22 m² per litre. German-language reviews on the page say bare or rough wood used more than that figure.
Do the written reviews come from the United Kingdom?
The sampled blocks are in German and are not marked United Kingdom. The 4.6 from 399 is the amazon.co.uk star line.
This amazon.co.uk listing is titled Osmo 009 Wood - Oils Larch - Oil Natural Shade 0.75L and is priced at £23.82, the same shelf price as the reviewed 0.75 litre Osmo 009 tin. The listing records water resistant, a first-available date of 31 October 2014, and a best-sellers rank of 658,960 in DIY & Tools. It has no part number, no star line, no review text, and no coverage or finish. The listing questions about garden furniture, rain and ease of use are unanswered. Treat it as a thin second listing of a 0.75 litre 009 tin, not as a better-value formula, and prefer the ASIN that actually shows 4.7 from 140 ratings if you are buying this size.
Pros
Cons
Best for: Only if this exact ASIN is the one in stock and you already know Osmo 009 from the fuller 0.75 litre listing.
Less suitable: A first purchase of larch oil, because the listing does not show reviews or a part number.
Specifications
Common questions
Does this listing show a star rating?
No. The listing has a price, a title, a best-sellers rank and the feature water resistant, and no customer-review line.
Is the price lower than the other 0.75 litre Osmo 009?
No. Both this ASIN and the reviewed 0.75 litre tin are £23.82 in this scrape.
Does the listing say it suits garden furniture?
The listing asks the question and does not answer it. Named use is not stated.
Four amazon.co.uk larch oil listings were scored from the stored listing files and the review notes already captured for each ASIN. This was not a weathering test, a slip test or a preservative trial. Amazon evidence takes half the score: a larger review count outranks a slightly higher star line, and a listing with no star line scores nothing on that block. Listing fit covers a named exterior use, a volume that matches the title, a pigment or finish line, and a water or coverage claim. UK-marked comments on colour and coverage score above written reviews that are German or Italian. Value is the shelf price in GBP divided by the title volume. The top pick is the highest score. The best value is the lowest price per litre among tins with a real review count. One of each.
Amazon evidence
50%Up to half the score. A larger amazon.co.uk review count outranks a slightly higher star line. 4.6 from 487 and 4.6 from 399 sit together. 4.7 from 140 scores a little lower. No star line scores 0. Stars are the listing average, not a lab test.
Listing fit
20%Points for a named exterior use, a volume that matches the title, a pigment or finish line, and a water or coverage claim. A missing part number, an unanswered use, and a volume field that contradicts the title cost points. Catalogue noise is not treated as a feature.
Review outcome
15%UK-marked comments on colour and coverage score higher than written reviews that are German or Italian. A listing with no review text scores 0. German praise is not rewritten as a UK verdict.
Value
15%Shelf price in GBP divided by the title volume. The lowest price per litre takes most of this block. A starless tin that shares a shelf price with a reviewed tin scores 0 here, because there are no reviews to treat that price as value.
Start with the timber and where it sits, then the colour, then the litres, then pounds per litre, then what the tin does not claim. The notes below follow that order. None of these listings was lab-tested.
Larch oil on amazon.co.uk is an exterior oil for larch decking, garden furniture and similar outdoor timber. Osmo’s tin in this set is Decking-Oil 009, which the maker describes as a transparent satin. Amazon titles call part 11500020 (0.75 litre) and part 11500021 (2.5 litres) larch oil. Bondex sells a separate Larches Oil in 3.0 litres. You separate them by oil line, litres, pigment and price per litre. Natural means a warm tan or orange tint, not a clear oil.
Natural on these oils means a warm tan or orange, not a colourless coat. UK reviews on the 2.5 litre Osmo 009 tin say the shade can look tan, orange or red-brown and can hide pale grain. Trial an offcut. If you needed clear, the description has to match that.
Osmo UK states about 24 m² per litre for one coat, and also 35 ml/m² on the same page. A rule of thumb is about 60 m² from 2.5 litres on smooth wood. Grooved boards and a second coat use more. German-language reviews on the Bondex page say bare wood used more than 22 m² per litre.
Larch heartwood is durability class 3–4 against fungi and sapwood is class 5. An oil does not change that. These bullets are weather and appearance claims. None of these listings shows a wood-preservative authorisation. Leaving a thick coat can keep the surface tacky.
The first check is the wood and where it sits. Larch oil in this set is for exterior larch, or another species the tin names, on decking or garden furniture. A clear UV product for vertical cladding is a different oil. A deck you want to leave silver is a clear oil that Osmo UK says has no UV protection, and that oil is not among these four listings. Heartwood durability is a property of the timber.
Buy litres for the surface you have, not for the headline on the tin. Osmo UK states about 24 m² per litre for one coat and also 35 ml/m² on the same page. A rule of thumb from the 24 m² figure is about 60 m² from 2.5 litres and about 18 m² from 0.75 litre for one smooth coat. One UK review says the 2.5 litre tin claims about 60 square metres. Bondex lists 22 m² per litre, and German-language reviews on that page say bare or rough wood used more.
Three typical situations, each with a recommendation from this comparison.
You want Osmo 009 on a deck or a run of outdoor furniture, and you have already tried the tint on an offcut. Osmo 009 larch oil 2.5 litres, part 11500021, is the top pick, at about £72.31 with 4.6 from 487 ratings. UK reviews say the natural shade is tan or orange, not clear. About £28.92 per litre.
You want Osmo 009 for a chair or a colour trial and you do not need 2.5 litres. The 0.75 litre tin, part 11500020, is about £23.82 with 4.7 from 140 ratings. About £31.76 per litre, it is the same oil at a higher price per litre. The written reviews on that listing are not marked United Kingdom.
You are oiling a large outdoor area and the priority is litres per pound. Bondex larch oil 3 litres, part 388158, is the best value, at about £30.36 with 4.6 from 399 ratings, about £10.12 per litre. It is a matte oil, not Osmo 009. A field that says 30 litres contradicts the title.
The top pick is Osmo 009 larch oil 2.5 litres, part 11500021, at about £72.31.
