EXTERIOR WOOD PAINT · ART. 850
Weatherproof wood paint that lets the timber breathe.
LEINOS 850 is an oil-based, silk-gloss paint for exterior timber: cladding, fences, sheds, gates and rough-sawn boards. The film stays elastic and lets water vapour out of the wood. Prime with 150, then two coats, in nine colours. Made in Germany.

These are opaque cover colours: the paint hides the wood, so the finished tone reads solid. The dried colour differs from the fresh paint in the tin, and batches can vary, so mix tins of the same colour together and brush a test board before the full job. Screen chips approximate the real paint.
Mixing the Nine
All nine colours mix with one another, so a shade can be adjusted on site. Mix in the tin, brush a test board and let it dry before you commit: the dried colour is the one that counts.
Mechanism & Use
How LEINOS 850 weatherproof paint works.
Paint on exterior timber fails when it cannot move or cannot let damp out. 850 is built to do both, and to hold its colour in sun and rain.
01
Three oils and natural resin
Linseed oil, wood oil and castor oil with natural resin esters form the binder. It dries by taking up oxygen from the air, so the coat needs air around it while it cures, and it goes on sparingly to dry through properly.
02
An elastic film that breathes
The cured film is elastic and open-pored. It follows the timber as it swells and shrinks, and it lets water vapour move back out of the wood instead of holding it behind a sealed film. It is weather- and UV-resistant.
03
Film protection against fungal attack
Iodopropynyl butyl carbamate, below 0.6 %, protects the paint film against fungal attack. It is declared on the label, and it is why 850 is an exterior paint, not a finish for toys or furniture.
04
Covers rough-sawn timber
Kaolin, chalk, silica and mineral pigments give the paint its hiding power. It is made for rough-sawn boards as well as planed ones, and the dried film is saliva- and sweat-resistant to DIN 53160.
Where It Lives
Where 850 lives
Timber cladding and board facades
Board-and-batten or shiplap walls on homes, cottages and resorts.
Fences and palisades
Boundary boards and pickets, rough-sawn or planed.
Garden sheds and store rooms
Small timber buildings that stand in sun and rain all year.
Gates and carports
Timber gates, posts and carport frames, in one of nine colours.
Rough-sawn outbuildings
Barns, staff quarters and farm buildings clad in unplaned boards.
Pergolas and garden structures
Posts, beams and screens: the vertical and overhead timber, not seating or decking.

What 850 is tested and declared for, and what it contains to protect the film.
Resistance
DIN 53160
The dried film is saliva- and sweat-resistant. Not a toy-safe claim: 850 contains a film biocide.
Protection
Film protection
Iodopropynyl butyl carbamate below 0.6 % guards the paint film against fungal attack.
Ingredient disclosure
InVeNa member
All fourteen ingredients are published, the film biocide included.
850 contains iodopropynyl butyl carbamate as film protection, which may cause allergic reactions, and it is harmful to aquatic life, so keep it out of drains. It is an exterior paint, not a finish for toys, furniture or food surfaces. Rags soaked with it can self-ignite: keep them in a closed metal tin or under water. The TDS is downloadable; the safety data sheet is issued on request — use Talk to LEINOS above.

How to Apply
Prepare the wood. It must be dry, sound, clean and free of grease and dust. Brush down untreated, rough-sawn timber with a stiff brush. Scrape out resin pockets and clean them with LEINOS Thinner 200.
Prime untreated, rough-sawn timber with Impregnation Wood Primer 150 and let it dry fully.
Stir the paint thoroughly before use. It is ready to use, no thinning needed. Mix tins of the same colour together if you have more than one batch.
Apply the first coat sparingly by brush, roller or airless spray, with air and surface above 15 °C. About 55–85 ml per m² (127–196 sq ft per litre) on planed wood, a little more on rough-sawn. Thick coats dry badly.
Apply the second coat after about 24 hours (dust-dry after about 12). Two coats are required. The paint dries with oxygen from the air, so do not paint in still, damp corners.
Clean brushes and tools with Thinner 200. Keep rags soaked with wet paint airtight in a metal tin or under water before disposal: they can self-ignite.
Application Conditions
- Air and surface temperature above 15 °C.
- The paint dries by taking up oxygen from the air: keep the air moving.
Coats & Recoating
- Two coats are required. Recoat after approx. 24 hours at 20 °C.
Cleaning & Storage
- Clean tools with LEINOS Thinner 200 straight after use.
- Store cool and dry. Unopened, it keeps for at least 2 years. Close opened tins tightly and decant leftovers into a smaller container; if a skin has formed in the tin, lift it off carefully and do not stir it in.

System & Substrates
Prime with 150, then two coats of 850.
Untreated, rough-sawn timber is brushed down and primed with Impregnation Wood Primer 150 first. Then two sparing coats of 850, a day apart.
The Coating System
Primer plus topcoat — the full chain.
Substrate Fit
850 works on — and what it doesn’t.
Suitable
Recommended substrates
- Exterior timber structures of all kinds
- Rough-sawn as well as planed timber
- Timber cladding and board facades
- Fences, palisades and garden sheds
- Gates, carports and pergola posts
Honest Limits
Where to use a different product
- Window rebates — the faces where the sash closes against the frame.
- Seating surfaces — benches, chairs and loungers.
- Floors and other horizontal surfaces exposed to the weather. For decks and terraces, use LEINOS 236 Terrace Wood Oil
- If you want the grain to show instead of a solid colour, use LEINOS 260 Premium Wood Varnish
Use With Care
Working safely with 850
- Contains iodopropynyl butyl carbamate (below 0.6 %). May cause allergic reactions.
- Repeated contact may cause dry or cracked skin.
- Harmful to aquatic life with long-lasting effects. Avoid release to the environment.
- Rags and materials soaked with wet oil can self-ignite. Keep them airtight in a metal container or under water, then dispose of them.
- Wear approved respiratory protection when spraying and a fine-dust mask when sanding.
- Keep out of reach of children.
Coverage & Pack Sizes
Pick the right tin for the job.
About 55–85 ml per m² per coat on planed or sanded wood; rough-sawn boards take a little more. Two coats are required.

Full Declaration
Composition
Every ingredient declared on the label. The Trust Hub explains what each one does and the standards behind it.
Linseed, wood and castor oil
Three plant oils form the binder. Linseed and wood oil dry in air into the paint film; castor oil keeps it supple.
Natural resin esters and micro-wax
Resin esters from natural resin give the film its body and silk-gloss; micro-wax adds water repellence.
Minerals and pigments
Kaolin, chalk, silica, alumina, mineral pigments and zinc oxide give the paint its colour and hiding power.
Isoparaffins, driers and film protection
Isoparaffins carry the paint and evaporate as it dries. Drying agents speed up the cure. Iodopropynyl butyl carbamate, below 0.6 %, protects the film against fungal attack.
Got Questions?
Frequently Asked
Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.
- 850 is oil-based, silk-gloss, comes in nine colours and can be brushed, rolled or sprayed over the 150 primer. Weatherproof Paint Water-Based 855 is solvent-free and matt, comes in Corn Yellow and Swedish Red only, is brushed on untreated timber and cleans up with water. It is not for oak.
- A rigid film cracks as timber swells and shrinks, and a sealed film can hold moisture behind it until it lifts. The 850 film is elastic and open-pored: it moves with the wood and lets water vapour move back out of it. Apply it sparingly; heavy coats dry badly.
- On untreated, rough-sawn timber, yes. Brush the wood down and prime it with Impregnation Wood Primer 150 before the two coats of 850.
- Two coats are required. At 20 °C and 50 % humidity the paint is dust-dry after about 12 hours and can be recoated after about 24. Paint above 15 °C, and make sure air reaches the surface: the film dries by taking up oxygen.
- Not on window rebates, seating surfaces, floors or other horizontal surfaces left out in the weather. For a deck use Terrace Wood Oil 236. And because it contains a film biocide, it is not a finish for toys, furniture or food surfaces.
- About 55–85 ml per m² per coat on planed wood, a little more on rough-sawn. A 2.5 litre tin covers roughly 30–45 m² per coat, so about 15–22 m² with the two coats the system needs. A 0.75 litre tin covers about 9–14 m² per coat.
