SOL-SILICATE FINE FACADE PAINT · ART. 612
The mineral facade colour that silicifies into the wall — and keeps it breathing.
LEINOS 612 ProfiSol Facade Paint Fine — a sol-silicate colour topcoat. Its silica-sol-and-water-glass binder silicifies into mineral and resin-bound facades alike and holds the tone at the highest stability class A1, in 200-plus alkali-fast pastel shades. The vapour-open colour finish of the ProfiSol facade system. Made in Germany by Reincke Naturfarben.

Facade Colour Range
Colour, on real mineral render.
Twelve of over 200 alkali-fast pastel shades, each shown on fine mineral render rather than a flat chip — because a silicate colour reads through the texture of the wall it sinks into. Highest colour-stability class A1, the class that holds a facade tone for decades.

Reseda Green
A sol-silicate paint reads as a matte mineral layer, not a plastic film — the tone sits in the render and is softened by its texture and the light on it. Each shade lists its RAL Classic code and carries a nearest NCS reference for specification. On WDVS/ETICS insulated facades, use only light shades (HBW > 40) to avoid heat build-up on the insulation. Screen renders approximate the paint on plaster — confirm the final match with a drawdown before specification.
Beyond the Twelve
The full facade palette runs to over 200 alkali-fast pastel shades, tinted to your specified colour reference with alkali-resistant pastes at our Delhi lab. Bring the architect’s spec — we match it, and advise the HBW-safe range for insulated facades.

Mechanism & Use
It silicifies into the wall — colour that is part of the facade, not a skin on it.
A silica-sol-and-water-glass binder bonds the pigment chemically into mineral and resin-bound facades, holds the tone at the highest stability class A1, and leaves the wall vapour-open. A mineral colour coat, not a plastic film.
01
Sol-silicate binder grips mineral and resin-bound facades
The silica-sol and potassium water-glass binder silicifies into the substrate, so the paint bonds chemically — not just mechanically — to lime and cement render, synthetic-resin plaster, sound matte silicone-resin and dispersion coatings, and WDVS/ETICS insulation alike. One facade colour across masonry and insulated walls, where most facade paints are tied to a single substrate family.
02
Highest colour stability, class A1
Alkali-resistant, lightfast mineral pigments in a silicate binder earn the top colour-fastness class A1 under BFS Merkblatt 26 — the facade holds its tone through years of UV and weather instead of fading and chalking to a washed-out version of the specified colour.
03
Vapour- and CO₂-permeable — the wall breathes
With an sd-value of just 0.01 m the mineral coat lets water vapour and CO₂ pass freely, so moisture is never trapped between substrate and paint. Through monsoon wet-and-dry cycles the finish does not blister or peel the way a sealed synthetic facade paint can.
04
Mineral, non-flammable, mould- and algae-preventing
It dries to a genuine mineral coating layer, not a plastic film — dead-matte, non-flammable, and alkaline at pH ≈ 11, which denies mould and algae a foothold from the coat itself rather than from a leaching biocide. Like every silicate finish it ages by an extremely slow reduction in layer thickness the trade calls chalking (Kreiden) — a material-typical property, not a defect.
Where It Lives
Where 612 Lives
New mineral-render facades
The colour topcoat on fresh lime/cement or mineral render, over a 611-and-610 prepared wall — a matte, vapour-open mineral finish in the specified shade.
Renovation repaints over sound old coatings
Repainting facades that carry sound matte silicone-resin or dispersion coatings. The sol-silicate binder bonds to the old coat and re-establishes a mineral, breathable finish.
WDVS/ETICS insulated facades
Vapour-open mineral colour over thermal-insulation composite systems. Light shades only (HBW > 40) so the insulation does not overheat behind a dark tone.
Heritage and conservation elevations
Historic plastered facades where a mineral, breathable, biocide-free colour coat matters. Silicate paint keeps the old fabric breathing while it holds a specified heritage tone.
High-exposure weather elevations
Wind- and rain-driven facades where colour-fastness and breathability decide the repaint interval. Class A1 stability and sd 0.01 m carry the finish through hard exposure.
Contemporary architectural colour facades
Specified pastel facade colour on modern Indian architecture — a matte mineral surface that reads as part of the wall, not a plastic skin, in over 200 alkali-fast shades.

How to Apply
Prepare the substrate. All surfaces are prepared per VOB Part C DIN 18363 and the BFS data sheets — clean, firm, dry, and load-bearing. Level hairline cracks and structural differences full-surface with LEINOS 610 ProfiGrund; consolidate very absorbent or friable substrates first with LEINOS 611 Profi-Fixativ. Assess doubtful substrates individually and lay a sample area.
Stir thoroughly and sieve. Silicate paint settles and skins in the pail — stir the LEINOS 612 bucket well and sieve the material to remove any dried particles from the rim or lid before use. This material-typical step gives an even, blemish-free coat.
Thin with Profi-Fixativ. Adjust the paint with LEINOS 611 Profi-Fixativ to suit the substrate and your method — about 5–15% for the base coat, about 5% for the final coat. The clear water-glass fixativ regulates absorbency and workability without weakening the mineral bond.
Apply in at least two thin coats. Work each coat thin and even in a cross-pattern (Kreuzgang), without overlaps, so contiguous surfaces read as one uniform plane — brush, roller, or airless. A further coat is recommended on facades with high weather exposure. Do not apply below +8°C, in direct sun, or on a heated substrate.
Lay the final coat. Apply the final coat after at least 12 hours, thinned about 5% with 611 Profi-Fixativ, for an even matte mineral finish in the specified shade. Each coat needs at least twelve hours before the next.
Protect while it cures. Allow at least 12 hours per coat; protect fresh coats from rain, direct sun, and heat. Do not apply below +8°C. Clean tools, substrate, and clothing immediately with water.
Application Conditions
- Apply at surface and air temperature above +8°C; do not apply in direct sun or on heated substrates.
- Protect fresh coats from rain; allow at least 12 hours between coats.
- Product is alkaline (pH ≈ 11) — mask and protect glass, natural stone, aluminium, and lacquered surfaces; wash off splashes at once with water.
- Silicate materials tend to dry on the rim and lid — stir and sieve the material before use for an even coat.
Coats & Recoating
- At least 2 thin coats in a cross-pattern; base coat thinned about 5–15% with 611 Profi-Fixativ, final coat about 5%.
- A further coat is recommended on facade surfaces with increased weather exposure. Allow at least 12 hours per coat (at 20°C).
Cleaning & Storage
- Clean tools, substrate, and clothing immediately and thoroughly with water. Do not let the silicate material set on brushes or rollers.
- Store cool, dry, sealed, and frost-free. Shelf life (unopened): at least 12 months. Opened containers and diluted material are not storable.

System & Substrates
The colour topcoat of the LEINOS ProfiSol facade system.
611 Profi-Fixativ consolidates and thins; 610 ProfiGrund levels and bonds the wall; ProfiSol Facade Paint Fine finishes it in colour. A mineral, vapour-open build-up — the finish silicifies into the facade rather than filming over it.

Honest Limits
Where to use a different product
- Wood and wood-based materials — the alkaline silicate stains and will not bond. Use the LEINOS wood-finish line instead, starting with LEINOS 290 Interior Hardwax Oil
- Clay (Lehm) and gypsum (Gips) substrates — not compatible with the water-glass chemistry.
- Plastics, glossy, and plasto-elastic surfaces — no absorbent mineral surface to silicify into.
- Salt-loaded or generally non-load-bearing substrates — assess and remediate first.
- Surfaces where water cannot drain and dry off — trapped moisture undermines the mineral build-up.
Use With Care
Working safely with 612
- The product is alkaline (pH ≈ 11). Protect eyes and skin from splashes — wear safety goggles/face protection and gloves during application. Wash any splashes off skin with plenty of water immediately.
- Mask and protect adjacent glass, natural stone, aluminium, and lacquered surfaces — the alkaline material can attack and stain them. Wash off splashes at once with plenty of water.
- Do not breathe vapours, spray mist, or dust. Ensure good ventilation and cover the surroundings of the coating area carefully.
- Keep away from children. The safety data sheet is supplied on request.
- Store the sealed pail cool, dry, and frost-free. Opened or diluted material is not storable; dispose of dried residues with construction waste, liquid residues per local regulations.

Frequently Asked
Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.
- It depends on the condition. Sound, non-chalking, well-bonded dispersion coatings can usually be primed with LEINOS Mineral Plaster Primer 622 first — the primer creates a uniform mineral base for the topcoat. Flaking, chalking, or oil-based finishes must be fully removed back to a sound mineral substrate.
- Yes. LEINOS mineral wall paints are fully breathable (vapour-permeable), allowing moisture to pass through the wall structure naturally.
- The surface must be clean, dry, and structurally sound. New plaster must be fully cured (typically 4 weeks). Prime with the recommended mineral primer.
- Natural white, Old white, and over 200 alkali-fast pastel shades, tintable with alkali-resistant tinting pastes; each curated LEINOS facade shade lists its nearest RAL Classic code with an NCS reference for specification. On WDVS/ETICS insulated facades use only light shades (HBW > 40) — a dark tone absorbs too much heat and can overstress the insulation behind it. On solid masonry the shade range is wider, but silicate chemistry favours mineral pastels over bright synthetic-organic colours.
- 612 ProfiSol is a sol-silicate paint: its silica-sol addition lets it bond not only to mineral render but also to sound synthetic-resin, silicone-resin, and dispersion coatings, so it suits both new mineral facades and renovation repaints over old coatings. 614 UniverSil is a pure mineral water-glass silicate paint aimed squarely at renovation — the mineralisation of synthetic-resin-coated facades, old dispersion and emulsion coatings, synthetic-resin renders, and WDVS — thinned simply with water. Both are matte, vapour-open, class-A1 mineral finishes; choose ProfiSol for a fresh mineral or premium build, UniverSil to re-mineralise an existing synthetic or emulsion facade.
- A silicate facade paint is applied thin — a heavy single coat cannot silicify evenly and can craze. At least two thin coats in a cross-pattern (Kreuzgang) build an even mineral layer with full colour and hiding power; a third is recommended on high-exposure facades. Each coat is thinned with 611 Profi-Fixativ — about 5–15% for the base coat, about 5% for the final coat — to regulate the draw on the substrate and keep the silicate bond sound. Allow at least twelve hours between coats.
- No. Unlike a synthetic-resin paint, a silicate coating does not form a plastic film — it forms a mineral coating layer, and it ages by an extremely slow reduction in layer thickness that the trade calls chalking (Kreiden). The TDS states this explicitly: chalking is a material-typical property of mineral silicate paint, not a product defect. It is part of how a mineral facade weathers honestly rather than cracking and peeling.
