MC-Bauchemie MC-DUR 1110 SL-IN
A three-component epoxy self-levelling topping engineered for a seamless, oil- and chemical-resistant 1 mm floor finish.
What is it?
MC-DUR 1110 SL-IN is a three-component, pigmented epoxy resin flooring system that self-levels into a smooth, seamless wear layer roughly 1 mm thick over a properly primed mineral substrate.
Where is it used?
Multi-level and surface car parks, petrol pump forecourts and vehicle wash bays, pharmaceutical and chemical manufacturing floors, food, beverage and dairy processing/bottling plants, and general industrial production areas.
Why use it?
It resists diesel, dilute acids and alkalis and a range of organic solvents, shrugs off abrasion from foot and light vehicle traffic, and leaves a jointless, easy-to-hose-down surface suited to hygiene-sensitive operations.
How is it applied?
Resin/pigment paste, hardener and filler are mixed in sequence with a slow paddle mixer, poured onto a primed or scratch-coated slab, spread with a steel float or squeegee, de-aerated with a spiked roller, and — where anti-skid texture is needed — broadcast with oven-dried quartz sand before sealing.

The technical insight
The data sheet’s numbers explain why this behaves differently on site than a thicker self-levelling epoxy. At a mixed density of 1.67 ± 0.05 g/cm³ and a 1000-micron (1 mm) per-coat film build, coverage works out to about 1.7 kg/m² per coat — leaner than the 2-3 kg/m² typical of 2-3 mm systems, which is part of why it gets specified where floor-to-frame clearance or existing floor levels are tight. Hardness development is staged: Shore D climbs from 60 at one day to 74 by seven days, alongside 7-day compressive strength above 50 N/mm², so early foot traffic is fine but full mechanical and chemical service should wait the full week. The 30-40 minute pot life at 30°C is the number crews most often underestimate in Indian summer conditions — batch sizes and applicator headcount need to match ambient temperature, not just floor area.
Where it is used
- Multi-level and open-deck car park wearing courses
- Petrol pump forecourts, fuel dispensing bays and vehicle wash areas
- Pharmaceutical manufacturing, packing and warehousing floors
- Food processing, beverage bottling and dairy plant floors
- Chemical storage, handling and blending area floors
- General industrial production and light-duty warehouse floors
- Workshop, service bay and garage floors exposed to oil and diesel drips
- Overlay resurfacing of sound, aged mineral floors needing a hygienic reseal
Key advantages
- Thin ~1 mm build adds minimal dead load or floor-to-door clearance loss versus 2-6 mm SL systems
- 7-day compressive strength above 50 N/mm² despite the thin film
- Resists diesel, dilute acids/alkalis and a broad range of organic solvents
- Seamless, smooth finish with no grout lines to trap dust or bacteria
- Bonds well to both concrete and steel transitions
- Anti-slip texture achievable via quartz-sand broadcast without changing the base system
- Comparatively quick turnaround — walkable in about a day, full service in 7 days
- Custom pigmented shades available for zone marking or branding
Limitations & considerations
- Substrate prep is unforgiving — needs >25 N/mm² concrete strength, ≥1.5 N/mm² pull-off and <5% moisture; shortcuts show up later as blistering
- 30-40 minute pot life at 30°C leaves little margin in Indian summer site conditions; batch size must match ambient temperature
- As a rigid epoxy it does not bridge live cracks or joints — moving cracks need a flexible system or a proper joint detail
- Chemical resistance is broad but not universal; strong oxidisers or unlisted solvents should be checked against the manufacturer’s resistance chart
- Three components must be batched in the correct 2.1:0.3:1.2:6.2 ratio — mis-batching on site affects cure and hardness
- Not intended as a permanent UV-exposed outdoor topcoat; sustained sunlight can dull or discolour the finish over time
Selection & best practice
Confirm substrate compressive strength (>25 N/mm²), pull-off strength (≥1.5 N/mm²) and moisture content (<5%) before ordering material, not after — the slab must also be at least 28 days old. Run a test patch on any repaired or previously coated floor. Keep site conditions inside the 10-30°C / ≤85% RH / 3K-above-dew-point window the data sheet specifies, and batch only what the crew can place within the 30-40 minute pot life at 30°C. Space Arc’s applicator teams sequence priming, scratch-coat and quartz-broadcast steps as one continuous pour to avoid cold joints.

Industry use cases
Multi-storey / surface car parks
Deck and ramp resurfacing where oil drips, tyre scuffing and periodic washdown demand a tough, seamless, chemical-tolerant wear layer without adding significant floor build-up.
Pharmaceutical & cleanroom-adjacent plants
Production and packing floors where a dust-free, jointless, easy-to-sanitise surface supports GMP housekeeping standards.
Food, beverage & dairy processing
Bottling lines and processing floors exposed to washdown chemicals, mild acids and frequent hosing, where hygiene and slip control both matter.
Fuel retail & vehicle service
Petrol pump forecourts and workshop floors where diesel, petrol and lubricant spills are routine and a quartz-broadcast anti-skid finish adds safety.
General industrial & warehouse floors
Light-to-medium duty production and storage areas needing a smart, easy-clean finish without the cost or build-up of a heavier trowel system.

How we position MC-Bauchemie MC-DUR 1110 SL-IN
Within MC-Bauchemie’s own MC-DUR flooring range, 1110 SL-IN is the thin-film specialist: pair it with an MC-Dur range primer for bonding, or step up to heavier trowelled/broadcast systems like MC-DUR 1200 or the MC-DUR PowerCoat hybrids where forklift or heavy-wheel traffic demands a thicker wear course, or to MC-Floor Screed BE/10 where the substrate itself needs levelling before any coating goes down. Outside the MC-Bauchemie stable, the closest like-for-like is Fosroc’s Nitoflor SL1000, a similarly thin (0.5-1.5 mm) self-levelling epoxy topping built for the same hygienic, chemically resistant flooring niche. Between the two, choice usually comes down to existing brand relationships and site logistics rather than a meaningful performance gap, since both are epoxy SL toppings engineered for comparable duty.
Fosroc Nitoflor SL1000 — Where a project has already standardised on Fosroc for waterproofing or repair scopes, Nitoflor SL1000 offers a comparable thin-film (0.5-1.5 mm) epoxy self-levelling topping under one brand warranty.
