LIME BRUSH RENDERING · ART. 667
Textured lime render for humid, mould-prone Indian walls.
LEINOS 667 — a fine-grained (0.13 mm), highly breathable lime render for interior walls and ceilings. Brushed or rolled on undiluted in two coats for a matt, hand-textured mineral surface; its high alkaline pH (≈13) makes the surface antibacterial and well suited to mould-prone damp rooms. Tinted on site with 668. Made in Germany by Reincke Naturfarben since 1985.

Mechanism & Use
How LEINOS 667 lime render works.
Matured lime putty cures by reaction with atmospheric CO₂ — each coat hardens into a microcrystalline calcium-carbonate surface chemically continuous with the mineral wall beneath. The wall keeps breathing, the fine grain gives a hand-brushed matt texture, and the high alkaline pH makes the surface antibacterial and well suited to mould prevention and remediation.
01
Carbonation binds the render to the wall
Matured lime putty (fat lime) is calcium hydroxide in water. As each coat dries, atmospheric CO₂ converts it into microcrystalline calcium carbonate — the same mineral the wall’s lime plaster is built from. A mineral surface continuous with the wall, not a film on top.
02
Breathable and moisture-regulating
The cured lime render stays open-pore. Water vapour passes freely in both directions — monsoon humidity absorbed and released, no condensation trapped behind a film. The render actively buffers the room’s moisture instead of sealing it in.
03
Antibacterial high-pH surface — suited to mould-prone rooms
Fresh and curing lime sits at pH approximately 13. The manufacturer states this high alkalinity makes the render antibacterial and well suited to mould prevention and remediation — the protection is the lime’s own high pH. (Not a tested antimicrobial specification; we make no such claim.)
04
Fine-grained texture, applied undiluted
At 0.13 mm grain, 667 lays down a soft matt hand-brushed texture a flat paint cannot reach. Ready to use — brushed or rolled on undiluted in two coats — the decorative character of a lime render with the mould-resistant chemistry of the lime line.
Where It Lives
Where 667 Lives
Coastal-humidity damp rooms and kitchens
Mumbai, Goa, Kochi, Chennai. A textured breathable lime surface where standard interior emulsion bubbles and peels under steam, monsoon humidity, and condensation. The vapour-permeable, high-pH lime chemistry handles the wall stress that defeats acrylic coatings. Avoid permanently wet shower zones and standing water.
Rajasthani heritage haveli interiors
Jaipur, Udaipur, Jodhpur, Bikaner heritage residences and hotels. A textured lime render compatible with centuries-old lime plaster — it cures into the wall’s own mineral matrix, keeping the heritage breathability alive with no plastic film and no seasonal repaint cycle.
Mould-remediation projects (Schimmelsanierung)
High-pH lime render specified over remediated walls in damp-prone buildings — the alkaline mineral surface is hostile to re-colonisation. Pre-treat any active mould growth with a dedicated remover first, then render with 667 as the durable breathable finish.
Decorative character feature walls
Contemporary Bangalore, Delhi, and Mumbai interiors wanting a hand-brushed matt mineral texture and tone-on-tone depth a flat paint cannot give. Tinted on site with 668 for custom heritage or contemporary shades.
Wellness studios, ayurvedic spas, yoga shalas
Health-led interior projects where solvent-free, breathable, mineral coatings are part of the air-quality story. No off-gassing and no plastic film between occupant and substrate.
Modern cement-plastered residential walls
Bangalore, Pune, Mumbai apartments and villas. Standard cement plaster (cured ≥ 2–3 weeks) over 622 primer. 667 reads as a soft textured heritage finish — the depth and character conventional emulsion cannot produce.

How to Apply
Substrate inspection & prep — wall must be dry, sound, absorbent, clean, free from efflorescence. Prepare all substrates to VOB/C DIN 18363; remove sinter skin mechanically from new plaster. New base plasters at least 2–3 weeks old. Test substrates with water-soluble, discolouring content by misting a small area; if brown or yellow streaks bleed through, seal with an appropriate insulating primer first. Fill holes and cracks with LEINOS 683 Lime Universal Scraper.
Prime chalking and highly absorbent surfaces with LEINOS 622 Mineral Plaster Primer (or 621 Silicate Primer). For sound, evenly absorbent lime or cement plaster older than 2–3 weeks, primer is optional — render directly. For chalking lime walls, very porous cement plaster, or patched repair zones with mixed substrate ages, priming first evens the absorbency canvas.
Stir thoroughly — the product is ready to use, applied undiluted. For colour, add up to 20% LEINOS 668 Pigment Concentrate — lime-fast pigments only — and mix to a uniform tint. Continue stirring during application to keep the lime particles suspended. In hot conditions the surface may skin faster; work in manageable sections.
First coat — apply evenly with a brush or wide masonry brush (or roller). Work in all directions so the fine 0.13 mm grain lays down uniformly and the texture reads consistent. Undiluted; avoid running and pooling on smoother patches. Full hiding power is achieved only after drying — the wet first coat looks translucent; this is normal.
Second coat after 24 hours at 20°C / 50% RH (longer at higher humidity). Apply the same way — brush or roller, all directions, undiluted. Brings the render to its uniform matt textured opacity. A faint cloudiness and sinter sheen appearing as it dries is the normal lime look, not a fault.
Cure & character — the lime render cures fully over 4–6 weeks through atmospheric carbonation; the chalky matt depth develops across this window, not on day two. Light cloud formation, glossy sinter patches, and gentle colour variation are the natural, material-typical look of a lime render — influenced by substrate, temperature, and humidity — not a defect.
Application Conditions
- Ambient and surface temperature above 5°C; substrate fully dry.
- New base plasters must be at least 2–3 weeks old before rendering.
- Avoid direct sunlight and strong air-draft during application and the first 24 hours of cure.
- Protect adjacent wood, glass, metal, and floor surfaces — lime is alkaline and stains permanently on raw wood and corrodes aluminium.
Coats & Recoating
- 2 coats, undiluted, depending on substrate.
- Recoatable after approx. 24 hours (at 20°C / 50% RH). Can be recoated many times.
Cleaning & Storage
- Clean tools immediately with water; LEINOS 930 Plant Soap for hardened residues. Do not use solvents on tools or skin.
- Store cool but frost-free (5–30°C). Shelf life (unopened): approx. 12 months.

System & Substrates
The textured lime render for interior absorbent mineral walls.
Two undiluted coats of 667 over sound mineral plaster — 683 to fill first, and 621/622 primer if the substrate is chalking or highly absorbent. Lime render behaves as a chemically continuous mineral surface, not a coating film.

Substrate Fit
667 works on — and what it doesn’t.
Suitable
Recommended substrates
- Lime plaster + lime rendering (heritage haveli interiors, conservation surfaces)
- Cement plaster (modern residential, commercial, after 2–3 week cure)
- Sand-lime brick, aerated concrete, and brick (interior face, sound and absorbent)
- Clay / loam plaster

Honest Limits
Where to use a different product
- Wood substrates — lime alkalinity stains raw wood permanently. Use the LEINOS wood-finish line instead, starting with LEINOS 290 Interior Hardwax Oil
- Metal — lime alkalinity corrodes aluminium and zinc on contact. Mask, prime with a primer designed for ferrous metals, or use a different coating.
- Glazed ceramic tile and non-absorbent surfaces — lime chemistry needs a porous mineral substrate to carbonate into.
- Gypsum board without primer — gypsum can react with calcium hydroxide over time. Always prime first with LEINOS 622 Mineral Plaster Primer
- Existing film-forming acrylic, silicone, or oil paint layers — strip back to the mineral substrate first.
- Exterior surfaces — use LEINOS exterior-mineral facade paints.
Use With Care
Working safely with 667
- Wear chemical-resistant gloves (nitrile) and safety goggles during application. Lime is alkaline — splashes cause serious eye damage (H318), not mere irritation. Contains calcium hydroxide.
- Avoid skin contact with wet render. Causes skin irritation (H315). Wash any splashes with plenty of water and soap immediately. Do NOT use solvents on skin.
- May irritate the respiratory tract (H335) — ventilate the workspace; wear a P2 respirator if sanding cured render or spraying.
- Mask and protect adjacent surfaces — raw wood, aluminium, zinc, glass, terracotta, and natural stone. Lime is permanently staining on raw wood and corrodes aluminium and zinc on contact.
- Keep away from children during application and the first 24 hours of cure. The cured wall surface (calcium carbonate) is inert and safe; wet render is not.
- Store the sealed pail cool but frost-free (5–30°C). Shelf life approximately 12 months unopened. Dispose of dried residues with household waste; liquid residues per local regulations.
Coverage & Pack Sizes
Pick the right pack for the wall.
Coverage on the card assumes one coat; two undiluted coats are the canonical specification. A textured lime render covers less area per litre than a flat paint. German TDS: 1 L ≈ 3–5 m²/coat (2.5 L ≈ 8 m², 10 L ≈ 30 m²).

Frequently Asked
Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.
- Many decorative finishes are wipe-clean once fully cured. Check the specific product for wet abrasion class rating.
- 2 coats, undiluted, depending on substrate. Recoatable after approx. 24 hours (at 20°C / 50% RH). Can be recoated many times.
- LEINOS decorative finishes have minimal odour from natural ingredients. The room can typically be used within 24 hours after application.
- Same lime chemistry, different form. 665 is a flat matt lime paint, diluted about 20% with water. 667 is a fine-grained (0.13 mm) textured lime render, ready to use and applied undiluted in a thicker build — a hand-brushed matt mineral surface with decorative character. Choose 665 for a smooth flat wall, 667 for texture.
- Yes. The German data sheet lists it as suitable for damp rooms and specifies its use in mould remediation (Schimmelsanierung) thanks to the high pH. The vapour-open lime surface handles steam and monsoon humidity without bubbling, and the alkaline pH ≈ 13 gives an antibacterial surface. Avoid permanently wet zones such as shower stalls and standing water — for those use a dedicated wet-area system.
- Yes, on site with LEINOS 668 Pigment Concentrate at up to 20% by volume. Critical restriction: only the sixteen lime-fast pigments survive the alkaline carbonation cure. The six exceptions are 323 Ultramarine Blue, 324 Ultramarine Violet, 335 Ultramarine Red, 336 Ultramarine Rotviolett, 337 Madder Dark Red, and 338 Madder Light Red; pearlescent 340 and 345 are also not lime-compatible and will fade. Each shade is marked for lime-fastness in the 668 index.
- Only for chalking or very absorbent surfaces — prime those with 622 Mineral Plaster Primer or 621 Silicate Primer to even the absorbency. On sound, evenly absorbent mineral plaster older than 2–3 weeks you can render directly. Fill any holes or cracks with 683 Lime Universal Scraper first.
- That is the natural look of a lime finish, not a defect. The German data sheet states that light cloud formation, glossy lime-sinter patches, and gentle colour variation are typical and depend on substrate, temperature, and humidity. The surface also ages by very slow chalking — a material-typical property of lime, and the reason it can always be re-rendered.
- Generally no. Lime render needs an absorbent mineral substrate to bond by carbonation. Acrylic emulsion, silicone, or oil films form a polymer skin the lime cannot penetrate. Strip existing film-forming coatings back to the mineral substrate, or re-plaster, before rendering with 667.
