STONE & CONCRETE IMPREGNATION · ART. 254
Stone and concrete oil that protects without changing the colour.
LEINOS 254 — penetrating impregnation oil for terracotta, absorbent tiles, and chemically neutral concrete. Water-repellent, abrasion-resistant, vapour-permeable. No film. No darkening.
No darkeningVapour-permeableVOC 420 g/lMade in Germany
Mechanism & Use
How LEINOS 254 stone and concrete oil works.
Penetrating impregnation that protects from inside the pore — water beads off, the surface stays open, the colour stays yours.
01
Oil penetrates into the mineral pore
Wood oil, linseed, castor, and sunflower oils travel into the absorbent pore structure of terracotta, concrete, and unglazed tile by capillary action. The stone itself becomes the carrier of the protection — not a film on top of it.
02
Resin ester locks it water-repellent
Natural rosin-ester resins cross-link the oils inside the mineral matrix. Water beads off the surface and rolls away rather than soaking into the grain. Spills wipe clean before they stain.
03
Surface stays vapour-permeable
Open-pore finish lets moisture vapour pass through the floor or wall — no plastic seal trapping monsoon humidity under concrete or terracotta. The screed breathes with the season, expanding and contracting freely.
04
Doesn’t significantly darken
Unlike acrylic and silicone sealers that wet the surface and deepen the colour permanently, 254 leaves the natural terracotta red or concrete grey visibly intact. The architect’s specified colour is what you see in five years.
Where It Lives
Where 254 Lives
Terracotta floors (haveli, courtyard, heritage)
Indian terracotta tiles, athangudi tiles, Mediterranean terracotta. Preserves the natural red colour while making spills wipeable. Re-apply every 2–3 monsoon seasons.
Polished and unsealed concrete floors
Modern residential lofts, design-led commercial interiors. Maintains the natural grey concrete look without acrylic “plastic” finish.
Cement grout joints (tile-floor systems)
Protect the grout as you protect the tile — the failure point in tile floors becomes the protected element. Apply post-grouting before regular use.
Unglazed stone and stoneware
Kota stone, granite cobble, terrazzo, unglazed ceramic basins and planters. Penetrates into the pore; does not film over the surface.
Heritage building restoration
Preservation-compliant treatment for protected structures where film-forming sealers are prohibited. Reversible — does not chemically bond with the substrate beyond the oil-resin cure.
Modern industrial and loft concrete floors
Bangalore + Mumbai design-led residential lofts, boutique studios, and commercial showrooms with polished or unsealed concrete. Preserves the natural grey concrete tone — no acrylic “wet-look” film.

How to Apply
Prepare the substrate — surface must be dry, clean, oil-free, and dust-free. Sweep, damp-mop, and let the floor dry completely (24–48 hours after washing). Remove cement laitance from new concrete with light mechanical abrasion. Remove salt efflorescence from older concrete with stiff brush — do not use acids. Old film coatings (acrylic, silicone sealers) must be stripped completely — 254 will not penetrate through a film finish.
Stir thoroughly — stir the tin until any settled solids are fully dispersed. Do not thin under normal conditions. Apply at ambient and surface temperatures above 10 °C; ensure cross-ventilation during the drying window. A floor fan during cure helps avoid odour build-up and supports even oxidation drying.
First coat — apply thinly and evenly with brush, lint-free cloth, roller, or sponge. On large floor areas a sponge or roller is the fastest tool; on tile grout joints and edges, brush gets into the recess. Allow 20–30 minutes penetration. Avoid puddles — the mineral pore absorbs what it absorbs; surplus oil will not penetrate.
Wipe excess after 20–30 minutes — the critical step. Wipe any unabsorbed oil off the surface with a clean lint-free cloth or pad. No oil film must remain — surplus oil will not dry properly and leaves a sticky surface. The wiped-off oil can be redistributed onto adjacent still-absorbent patches.
Second coat — next day, same technique. Apply thinly and evenly with sponge, brush, or roller. Same wipe-off discipline: 20–30 minutes penetration, then remove excess. On highly absorbent substrates (old terracotta, very porous concrete) apply an optional third thin coat after the second cures.
Maintenance — cure 7–10 days at 18–22 °C. Light foot traffic after 24 hours; heavy traffic after full cure. Maintenance recoat: when the surface stops beading water or starts to look dry, clean and re-apply 254 directly. No sanding, no stripping — re-oil into the existing oil-impregnated pore.
Application Conditions
- Ambient and surface temperature above 10 °C.
- Substrate must be dry, clean, oil-free, dust-free.
- Cross-ventilate during drying window — a floor fan supports even cure.
- Do not apply over film-forming sealers (acrylic, silicone) — strip first.
Coats & Recoating
- Two thin coats standard. Optional third coat for highly absorbent or old terracotta. Recoatable after 4–6 hours; next-day second coat preferred for best penetration. No sanding between coats.
Cleaning & Storage
- Clean tools immediately after use with LEINOS Verdünnung 200 (thinner) or white spirit.
- Store unopened tin cool, dry, frost-free. Shelf life at least 2 years in sealed packaging.

System & Substrates
Penetrating impregnation — no primer, no topcoat, mechanical prep only.
Two thin coats of 254 directly on prepared mineral surface. There is no primer in the LEINOS mineral-impregnation system. No film topcoat: the protection lives inside the mineral pore. Reversible — critical for heritage and preservation-controlled installations.

Substrate Fit
254 works on — and what it doesn’t.
Suitable
Recommended substrates
- Absorbent terracotta tiles (Indian, athangudi, Mediterranean)
- Unglazed clay tiles, brick pavers
- Chemically neutral concrete (28+ days cured)
- Polished and unsealed concrete floors
- Cement grout joints (post-grouting)
- Unglazed stoneware (sinks, basins, planters, non-food)
- Kota stone, granite cobble, terrazzo (unsealed)
Honest Limits
Where to use a different product
- Glazed ceramic and porcelain tiles — non-absorbent; oil cannot penetrate and will sit as a residue.
- Sealed concrete with intact acrylic or silicone film — strip the film coating first.
- Polished marble and acid-etched limestone — chemically reactive substrates not suited to oil-resin chemistry.
- Permanently wet or submerged surfaces — pools, sunken courtyards. Oil-resin cure requires air exposure.
- Food-contact surfaces (kitchen worktops, sinks for food prep) — use LEINOS 280 Countertop Oil
Use With Care
Working safely with 254
- Store away from children.
- Risk of spontaneous combustion of oil-soaked materials. Store used cloths in a sealed metal container filled with water or dispose of safely.
- Ensure adequate ventilation during drying window. Solvent vapours are heavier than air.
- Wear respiratory protection when spraying.
- Do not allow to enter surface water or drains.

Full Declaration
Composition
Every ingredient declared on the label. The Trust Hub explains what each one does and the standards behind it.
Wood Oil (Tung)
Tung-tree seed oil, plant-derived. Water-resistance partner alongside linseed for faster initial cure and stronger spill-resistance on mineral substrates.
Linseed Oil
Cold-pressed flax-seed oil — the LEINOS signature drying oil. Polymerises with oxygen inside the mineral pore. Plant-based, traditional natural-paint pedigree.
Castor Oil
Plant-derived elasticity additive. Stays slightly flexible inside the cured matrix — matters on substrates that move with thermal cycling and moisture migration.
Sunflower Oil
Plant-derived carrier extension for very fine pore networks. Improves flow into dense terracotta and polished concrete where heavier oils alone do not penetrate efficiently.
Natural Resin (Rosin Ester)
Pine-derived natural resin ester. Cross-links the cured oils into the mineral pore matrix — the “resin” in the brand’s oil-resin chemistry. No surface film.
Isoaliphatic Carrier (Isoparaffins)
Plant-derived hydrocarbon thinner. Evaporates during cure, leaving the oil-resin matrix bonded in the mineral pore. Carries the VOC declaration (420 g/l, Cat. f).
Driers
Manganese, zirconium, and zinc neodecanoate driers (cobalt-free) accelerate the oxidative polymerisation of the oil-resin matrix. Disclosed per InVeNa full-disclosure pledge.
Got Questions?
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.
- Not significantly. 254 preserves the natural colour of the substrate — the architect’s specified terracotta red or grey concrete stays visibly intact. A subtle deepening of tone may appear on highly absorbent old terracotta during the first cure week and dissipates as the resin cross-links. For comparison: acrylic and silicone sealers wet the surface and deepen the colour permanently; 254 leaves the substrate looking like itself.
- Acrylic and silicone sealers form a film on top of the surface. They look wet and shiny initially, deepen the colour permanently, and crack within 2–3 monsoon seasons when humidity drives moisture from below the screed upward through the floor. 254 penetrates into the mineral pore. The colour stays natural, the floor stays vapour-permeable, the screed breathes, and there is no film to delaminate. Re-application does not require stripping the previous treatment.
