FAST-DRYING LACQUER PRIMER · ART. 810
The lacquer primer that keys bare wood, metal and stone.
LEINOS 810 — a fast-drying, biocide-free plant-oil primer for interior and exterior woodwork, metal and stoneware. Easily sanded, good filling and opacity, water-vapour permeable — the natural-white foundation for the LEINOS lacquer system.

Mechanism & Use
How LEINOS 810 resin lacquer primer works.
A fast-drying plant-oil primer that keys the surface, fills the grain and sands smooth — biocide- and aromatic-free, water-vapour permeable.
01
Plant-oil binder keys the surface
A plant-oil binder cures in air into a waterproof, elastic film that grips bare wood, metal and stone and gives the lacquer something firm to hold.
02
Titanium dioxide and fillers cover and fill
Titanium dioxide gives natural-white opacity while chalk and talc fill the grain and build an even, easily-sanded body.
03
Fast-drying, easily sanded
Dust-dry in about three hours and ready to sand and recoat the next day, so the lacquer system moves fast.
04
Biocide-free, aromatic-free
No in-can biocides and a dearomatised solvent, water-vapour permeable — made in Germany by Reincke Naturfarben.
Where It Lives
Where 810 lives
Windows and doors
Keying dimensionally-stable joinery before a silk-gloss lacquer.
Gates, sheds and soffits
A firm foundation on exterior wood that moves with the seasons.
Metal and steel
Railings, grilles and gates that need a keying primer before colour.
Stoneware and mineral surfaces
A bonding base for lacquer on stone.
Interior stairs and floors
A sandable primer under hard-wearing opaque colour, indoors.
Renovation over old coats
A fresh, sandable base once flaking paint is removed.

The honest anchors that let specifiers put 810 under exterior joinery, metalwork and interior floors — no over-claiming.
810 is the film-forming foundation of the LEINOS lacquer system — biocide- and aromatic-free, water-vapour permeable, made in Germany. It is a solvent-borne primer, not a toy- or food-safe finish, so clean tools with Verdünnung 200 rather than water and store oil-soaked rags under water or in a sealed metal tin. The TDS is downloadable; the full SDS is available to architects and contractors on request — use Get Expert Advice above.

How to Apply
Prepare the substrate — the surface must be dry, firm, clean, grease- and dust-free and only slightly absorbent. Strongly absorbent or rough-sawn wood is deep-primed with LEINOS priming oil first.
Stir the primer — stir 810 thoroughly before use; if a skin has formed in the tin, lift it out rather than stirring it in.
Apply one sparing coat — brush, roll or spray a single thin, even coat at surface and air temperatures above 15 °C. Apply sparingly, because too heavy a film dries poorly.
Let it cure with airflow — dust-dry in about three hours. The film cures by taking up oxygen, so keep a fan running for air circulation and low odour while it dries.
Sand to a smooth key — after 24 hours, sand with 150/180 grit and dust off to leave an even, matt key for the lacquer.
Build the lacquer system — overcoat with White Lacquer 820, Finishing Lacquer 840 or custom Mix 845. Clean tools with LEINOS Verdünnung 200 (not water) and store oily rags under water or in a sealed metal tin.
Application Conditions
- Temperature above 15°C.
Coats & Recoating
- One sparing coat. Sandable and recoatable after 24 hours; then overcoat with White Lacquer 820, Finishing Lacquer 840 or Mix 845.
Cleaning & Storage
- Clean tools immediately after use with LEINOS Verdünnung 200 (thinner). Do not use water.
- Store in a dry and cool place, protect from freezing. Shelf life in closed packaging is at least 2 years.

System & Substrates
One coat of 810, then two coats of 840. That’s the lacquer system.
On bare wood, metal or stoneware, prime once with Resin Lacquer Primer 810 — then build with White Lacquer 820, Finishing Lacquer 840, or custom-tinted Mix 845.
The Coating System
Primer plus topcoat — the full chain.
Substrate Fit
810 works on — and what it doesn’t.
Suitable
Recommended substrates
- Windows and doors — dimensionally-stable joinery
- Garden sheds, roof soffits and exterior gates
- Fences, carports and palisades
- Metal and steel — railings, grilles, gates
- Stoneware and mineral surfaces
- Interior wooden stairs and floors
Honest Limits
Where to use a different product
- Strongly absorbent or rough-sawn wood — deep-prime with LEINOS priming oil first, then 810.
- Exterior floors and stairs — on floors, 810 is for interior use only.
- For a clear finish that shows the wood grain instead of an opaque lacquer system, use LEINOS 236 Terrace Wood Oil
Use With Care
Working safely with 810
- Keep away from children.
- Oil-soaked rags and materials can self-ignite — store under water or in a sealed metal container until disposal.
- Wear respiratory protection when spraying; wear a fine-dust mask when sanding.

Full Declaration
Composition
Every ingredient declared on the label. The Trust Hub explains what each one does and the standards behind it.
Plant-oil binder
The film former — it oxidatively cures in air into a waterproof, elastic film that keys the surface and flexes with the substrate instead of cracking.
Titanium dioxide, chalk & talc
Titanium dioxide gives the natural-white opacity and covering power; chalk and talc fill the grain and build the easily-sanded body.
Isoparaffins
A dearomatised (aromatic-free) hydrocarbon carrier that lets the primer flow out, then evaporates during cure. Clean tools with LEINOS Verdünnung 200, not water.
Drying agents
Metal-soap driers catalyse the oxidative cure so the coat is sandable the next day and ready for the lacquer.
Got Questions?
Frequently Asked
Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.
- Oils penetrate the wood and enhance the natural grain, while lacquers form a protective film on the surface for higher mechanical resistance.
- Generally no. Lacquer requires a clean, untreated or sanded surface. Oil residues prevent proper adhesion of the lacquer film.
- Light sanding between coats (P220-P320) and applying thin, even layers are key. Avoid over-brushing to prevent visible brush marks.
- On bare wood, metal or stoneware, yes. 810 gives the lacquer its grip, fills and seals the surface, and because it dries natural-white it brings the topcoat colour up in fewer coats. Skip it and you risk poor adhesion, patchy colour and a coat that lifts. One sparing coat, sanded at 24 hours, then White Lacquer 820, Finishing Lacquer 840 or Mix 845.
- No. 810 is a solvent-borne primer with an isoparaffin carrier and metal-soap driers — biocide- and aromatic-free, but not toy- or food-safe. For children’s furniture use the water-based Wax Varnish 600; for food-contact or barefoot interior wood use a toy-safe finish such as Interior Hardwax Oil 290.
