COARSE SOL-SILICATE FACADE GROUND COAT · ART. 613
The coarse ground coat that grips mineral and synthetic facades alike — then takes the fine finish.
LEINOS 613 ProfiSol Facade Paint Coarse — a fibre-reinforced, coarse-grain sol-silicate ground coat. Its silica-sol-and-water-glass binder grips mineral render and sound synthetic coatings alike, laying a cloth-matt, scattered-light mineral structure that levels small hairline cracks. Overcoated with ProfiSol Facade Paint Fine 612. Made in Germany by Reincke Naturfarben.

Mechanism & Use
It grips, structures, and levels — then takes the finish.
Silica sol and water-glass bond the coat to mineral and non-mineral facades alike; a fibre-reinforced coarse grain builds a scattered-light mineral structure and evens small cracks, and the wall keeps breathing. A mineral ground coat, not a plastic filler.
01
Sol-silicate binder grips mineral and non-mineral facades
The silica-sol and potassium water-glass binder 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 coarse mineral ground coat across masonry, insulated, and previously-synthetic facades, where most base coats are tied to a single substrate family.
02
Fibre-reinforced coarse grain builds a scattered-light structure
A graded coarse mineral filler (0.4 mm) and fibre reinforcement give the coat body: it lays a cloth-matt, scattered-light mineral structure and evens small hairline cracks and structural differences full-surface, so the fine facade finish lands on a uniform, structured plane instead of tracing every craze line beneath it.
03
Vapour- and CO₂-permeable — the wall breathes
The mineral coat lets water vapour and CO₂ pass freely, so moisture is never trapped between substrate and finish. Through monsoon wet-and-dry cycles the build-up does not blister or peel the way a sealed synthetic base coat can.
04
Mineral, non-flammable, mould- and algae-preventing
It dries to a genuine mineral coating layer, not a plastic film — 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 613 Lives
New mineral-render facades
The coarse ground and intermediate coat on fresh lime/cement or mineral render, laying a scattered-light mineral structure and levelling small cracks before the ProfiSol Fine 612 colour finish lands on a uniform plane.
Renovation over sound synthetic coatings
Where a firmly adhering matte silicone-resin or dispersion old coat is renovated to a mineral facade, the sol-silicate binder grips the old coating and re-establishes a mineral, breathable, structured base for the fine finish.
WDVS/ETICS insulated facades
A coarse, vapour-open mineral ground over thermal-insulation composite systems — grips the render coat and evens fine structural differences, keeping the system breathable. Light shades only (HBW > 40) so the insulation does not overheat.
Heritage and conservation elevations
Historic plastered facades where a mineral, breathable, biocide-free base coat matters. The coarse silicate ground keeps the old fabric breathing while it structures the surface for a mineral finish.
High-exposure weather elevations
Wind- and rain-driven facades where the durability of the build-up depends on the foundation. A well-bonded, vapour-open coarse ground under ProfiSol Fine 612 carries the mineral system’s longevity from the base up.
Coarse-textured architectural facades
Contemporary Indian elevations that want a structured, cloth-matt mineral surface rather than a flat film. The coarse grain gives the facade its scattered-light texture beneath the fine colour finish.

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. Repair holes and break-outs with a structurally matching material and let them dry fully; 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 613 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 coarse coat.
Thin with Profi-Fixativ. Adjust the coat with LEINOS 611 Profi-Fixativ to suit the substrate and your working method — brush, roller, or airless. The clear water-glass fixativ regulates absorbency and workability without weakening the mineral bond.
Apply the coarse coat full-surface. Work the coat evenly across the whole wall — brush is recommended, roller or airless also work — building the coarse, cloth-matt, scattered-light structure. Slurry every hairline crack carefully and smooth the transitions so the surface reads as one uniform plane. Do not apply below +8°C, in direct sun, or on a heated substrate.
Let it dry, protected. Allow at least 12 hours before overcoating; protect the fresh coat from rain, direct sun, and heat while it sets. Silicate ground coats need this window to firm up into a sound mineral plane.
Overcoat with the fine finish. ProfiSol Coarse is a ground coat, never a finish — overcoat it with LEINOS ProfiSol Facade Paint Fine 612, which sets the visible facade colour and the weathering surface. 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 before overcoating.
- 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
- One full-surface coarse ground and intermediate coat, thinned with 611 Profi-Fixativ as needed.
- Overcoat with ProfiSol Facade Paint Fine 612 after at least 12 hours (at 20°C) — the fine coat sets the facade colour.
Cleaning & Storage
- Clean tools, substrate, and clothing immediately and thoroughly with water. Do not let the silicate material set on brushes, rollers, or paddles.
- Store cool, dry, sealed, and frost-free. Shelf life (unopened): at least 12 months. Opened containers and diluted material are not storable.

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 bond with.
- 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 613
- The product is alkaline (pH ≈ 11) and can irritate skin and eyes. 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.

Full Declaration
Composition
Every ingredient declared on the label. The Trust Hub explains what each one does and the standards behind it.
Mineral Water Glass
Potassium water-glass — the mineral binder. It silicifies into lime and cement render and becomes a mineral coating layer of the wall rather than a plastic film. Solvent-lean, water-borne.
Silica Sol (Kieselsol)
A colloidal silica sol that extends the silicate bond to non-mineral substrates — sound matte silicone-resin and dispersion coatings — so this coarse ground grips where a pure silicate coat could not.
Fibre reinforcement + coarse mineral fillers (0.4 mm)
Fibres bridge hairline cracks while a graded coarse mineral filler gives the coat its body and scattered-light structure — enough to even small cracks and structural differences in one full-surface ground coat.
Alkali-resistant, lightfast mineral pigments
Mineral pigments (including titanium-dioxide white) chosen to survive the alkaline binder — the basis of the Natural white, Old white, and 200-plus alkali-fast pastel shades the coarse coat is tinted to.
Organic additives (< 5%)
A small organic additive fraction (under 5%, per VOB/C DIN 18363 2.4.1) for workability, without compromising the mineral, vapour-open character of the coat.

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.
- Yes. ProfiSol Coarse is a ground and intermediate coat, never a finish — the TDS specifies that it must be overcoated with LEINOS ProfiSol Facade Paint Fine 612. Its job is to grip the substrate, build a scattered-light mineral structure, and level small hairline cracks; the fine 612 coat over it sets the visible facade colour and the weathering surface.
- They do different jobs and are often used together. 610 ProfiGrund is a fibre-reinforced quartz filler-primer with heavy body — it levels deeper hairline cracks, plaster repairs, and structural differences full-surface. 613 ProfiSol Coarse is a sol-silicate coarse ground and intermediate coat — its silica-sol binder grips non-mineral substrates too (matte silicone-resin, dispersion coatings, WDVS/ETICS) and it lays the cloth-matt, scattered-light mineral structure directly beneath the fine finish. On a typical renovation: 611 consolidates the raw wall, 610 levels the deeper repairs, ProfiSol Coarse structures the surface, then ProfiSol Fine 612 finishes it in colour.
- Yes — that is one of its strengths. The silica-sol addition lets ProfiSol Coarse bond not only to mineral render but also to sound, firmly adhering matte silicone-resin and dispersion coatings, and to WDVS/ETICS insulation. It re-establishes a mineral, vapour-open, structured base over the old coating, which the ProfiSol Fine 612 finish is then applied over. Glossy or plasto-elastic coatings are not suitable — assess doubtful substrates individually and lay a sample area first.
- 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 coatings, not a product defect. It is part of how a mineral facade weathers honestly rather than cracking and peeling.
