MC-Bauchemie MC-Floor 13
A factory-premixed, polymer-modified cementitious topping and screed that gives worn or new industrial floors a hard, dense, dust-free wearing surface built for forklift traffic.
What is it?
A single-component, polymer-modified cementitious floor topping and levelling screed that combines Portland cement, redispersible polymer powder and graded hard aggregate in one factory-blended bag.
Where is it used?
Heavy-duty industrial floors — factories, warehouses, logistics hubs, car park decks, food and cold-storage plants — both for new slabs and for refurbishing worn concrete.
Why use it?
It delivers several times the abrasion resistance of plain concrete and seals off surface dusting, so floors take constant wheeled traffic without ravelling or generating fines.
How is it applied?
Mixed with clean water, placed as a bonded topping from 10 to 50 mm or an unbonded screed from 30 to 75 mm, then floated and trowelled to a dense, closed finish.
About MC-Bauchemie MC-Floor 13
MC-Floor 13 is the layer that decides how long an industrial floor actually lasts. The structural slab underneath rarely fails first — it is the top few millimetres, hammered by steel wheels, pallet trucks and point loads, that break down, dust and pothole. This topping is engineered specifically for that duty. It arrives as a factory-premixed powder that blends Portland cement, a redispersible polymer modifier and carefully graded hard aggregate, so the site crew only adds clean water and controls the finish. There is no separate resin to gauge, no aggregate to broadcast by hand and no batch-to-batch guesswork on the mix.
For engineers and contractors across Delhi NCR and the wider Indian market, its real value is flexibility on a live project. The same product lays down as a thin bonded topping over a sound existing slab or builds up as a thicker unbonded screed where levels have to be corrected or a fresh wearing course is needed. That makes it as useful for a refurbishment shutdown — where you are grinding back a tired warehouse floor over a weekend — as it is on a new-build shed. Space Arc supplies MC-Floor 13 as an authorised distributor and, where required, applies it with trained crews, so specification, material and workmanship stay under one accountable roof.
The technical insight
The performance comes from the polymer, not just the cement. In a plain cement screed the paste is porous and the bond between paste and aggregate is the weak link, which is exactly what wheeled traffic exploits — it plucks fines out of the surface and the floor starts to dust. MC-Floor 13 carries a redispersible polymer powder that reactivates when the mix water is added and forms a continuous polymer film through the hardened matrix. That film does three things at once: it bridges microcracks and lifts flexural and tensile capacity, it grips the substrate so the topping bonds monolithically rather than sitting as a loose layer, and it slashes water absorption so the surface is far denser and less permeable. Blend that tougher, lower-porosity matrix with hard graded aggregate and the wearing course resists the ploughing and impact of forklift wheels several times better than ordinary concrete — while the closed, dust-proofed surface stops the floor shedding fines into a clean production or storage environment.
Where it is used
- Manufacturing and plant floors subject to continuous forklift and pallet-truck movement
- Warehouse and logistics-centre floors, including aisle and racking bays
- Refurbishment and re-topping of worn, dusting or spalled concrete slabs
- Suspended and ground-level car-park decks needing a durable wearing course
- Food, beverage and dairy processing areas requiring a dense, cleanable surface
- Cold-storage and freezer-room floors
- Loading bays, ramps and dispatch areas taking impact and point loads
- Levelling and re-profiling of out-of-tolerance slabs ahead of a wearing course
Key advantages
- Three to five times the abrasion resistance of standard concrete, so floors last far longer under traffic
- Polymer-densified surface that is dust-proof and easier to keep clean
- Strong monolithic bond to the substrate with improved flexural strength
- Factory-premixed for consistent quality — only clean water is added on site
- Reduced water absorption gives better resistance to spillage and mild chemical attack
- One product serves both thin bonded toppings and thicker unbonded screeds
- Suited to both new construction and fast-turnaround refurbishment
- Applied by float and trowel with familiar site tools and skills
Limitations & considerations
- It is a cementitious wearing course, not a chemical barrier — for aggressive acids, fuels or hot spillage a resin coating or MC-Bauchemie MC-DUR system is needed on top
- Not a decorative finish; where colour, gloss or a seamless resin look is required, a floor coating must follow
- Placement thickness limits apply — below the minimum it will not bond reliably, above the maximum it should be built up in layers or as a screed
- Bond and durability depend on substrate preparation; a weak, laitance-covered or contaminated slab will compromise results
- Like all cement systems it needs proper curing and protection from rapid drying, and cannot be trafficked until adequately hardened
Selection & best practice
Success starts below the topping. Mechanically prepare the substrate by grinding, scabbling or shot-blasting to remove laitance, curing compounds and contamination, and expose a sound, open-textured surface. For a bonded topping, pre-wet the slab to a saturated surface-dry condition or use a slurry bond coat, and place the topping wet-on-wet so it keys in. Gauge mixing water accurately — roughly 3.5 to 4.0 litres per 25 kg bag — because over-watering is the single biggest cause of a weak, dusting surface; use a forced-action mixer for a consistent, lump-free mix. Place to the correct thickness for the method (10 to 50 mm bonded, 30 to 75 mm unbonded), consolidate, then float and trowel to a tight, closed finish. Cure thoroughly to prevent early moisture loss and hold back traffic until the topping has gained adequate strength. On refurbishment work, always sound out the existing slab first and repair any delaminated or unsound areas before topping over them.

How we position MC-Bauchemie MC-Floor 13
MC-Floor 13 sits in the middle of a floor build-up: it is the tough cementitious wearing course, not the final chemical or decorative layer. Within the MC-Bauchemie family, pair it with an MC-DUR epoxy or polyurethane coating where the floor faces aggressive chemicals, fuels or a hygienic seamless finish, and specify an MC-Bauchemie curing agent to protect the fresh surface. For a lighter-duty or faster-turnaround job, MC-Bauchemie’s MC-Floor Screed range offers alternative rapid and levelling screeds. Where the floor is a brand-new slab being finished wet-on-wet rather than an existing surface being re-topped, a dry-shake surface hardener from our other brand lines is often the more economical route to the same hard, dust-free result. Space Arc can specify across all of these from a single point.
Fosroc Nitoflor Hardtop — Choose the Fosroc dry-shake hardener when the floor is a fresh concrete slab being finished monolithically wet-on-wet, rather than an existing surface that needs a separate bonded topping.
