About MC-Bauchemie MC-Floor Screed

Every industrial floor eventually loses a fight with forklift wheels, rack-post point loads, or a dropped pallet, and the resulting spall or pothole is rarely convenient to repair. Conventional patch mortars and screeds solve the durability problem but not the scheduling one — most need seven to twenty-eight days before they’re rated for vehicle traffic, which means either running the plant around a cordoned-off bay for weeks or losing production days outright. MC-Floor Screed was built specifically to close that gap: a matched bond-coat-plus-screed system that trades a little of the working window for a lot of speed, so a maintenance team can cut out, rebuild, and hand back a damaged section within a single shutdown window.

Space Arc Engineering deploys the system across the Delhi NCR industrial belt — Manesar, Bawal, Faridabad, Neemrana — for auto-component plants, FMCG and pharma warehousing, and cold-chain logistics operators, where an idle bay costs far more per hour than the repair material itself. Because it’s a system rather than a single product, getting the sequencing and batching right matters more than with an ordinary screed, which is why we run it with crews trained on MC-Bauchemie’s own application procedure rather than treating it as an off-the-shelf bag mix.

The technical insight

The speed comes from two separate design choices working together. MC-Floor Screed 10 is polymer-modified — a redispersible polymer powder in the cement mix improves adhesive bond to the old concrete and tightens the pore structure, which is also why the manufacturer states it hardens virtually free of shrinkage and stress; that matters because a rapid-set repair that shrinks away from its edges just creates a new crack line. MC-Floor Screed 25, the aggregate-extended grade for heavier-wear repairs, uses a fast-reacting special binder rather than an accelerated ordinary Portland cement mix, and is explicitly chloride-free with low chromate content — meaning the speed isn’t bought with a calcium-chloride accelerator that would otherwise risk corroding nearby reinforcement or dowel bars, a real concern in reinforced industrial slabs.

Where it is used

• Weekend or shutdown-window repair of spalled or potholed production-floor concrete ahead of Monday-morning traffic
• Re-profiling forklift wheel-track rutting and racking-aisle wear in warehouses and logistics docks
• Building fall and levelling a substrate before an epoxy, PU or resin topping goes down in food, pharma or FMCG plants
• Patch repair around floor drains, machine foundations, dowelled joints and pit edges in industrial floors
• Reinstating floor slabs after equipment relocation, rack removal or utility trenching
• Rebuilding worn dock-leveller aprons and approach ramps under constant truck traffic
• Fast-track repair ahead of plant shutdowns with a fixed, short reopening window
• Levelling substrates before tiling or coating in commercial or institutional floors where downtime is costly

Key advantages

• Trafficable in roughly 24-48 hours versus the 7-28 days a conventional screed repair needs to cure
• MC-Floor Screed 10 cures virtually free of shrinkage and stress, cutting the risk of fresh cracking at the repair edge
• Pumpable, self-levelling grade speeds large-area placement without hand-trowelling every square metre
• Screed 25’s chloride-free, low-chromate binder is safe to use close to reinforcement and dowel bars
• A matched bond-coat-plus-screed system removes the guesswork of pairing a primer with the wrong topping
• High early strength supports fork-lift, rack-post and pallet-truck loading soon after placement
• Cuts production-downtime cost, which on a running plant floor usually dwarfs the material cost itself
• Full manufacturer documentation — TDS, SDS, DoP, EPD — available for QA and green-building records

Limitations & considerations

• Fast-reacting chemistry means a short working window; batching and finishing must be disciplined and is unforgiving for an inexperienced crew
• Material cost per square metre runs well above an ordinary sand-cement screed, which has to be justified by the downtime actually saved
• Needs the damaged concrete cut back to genuinely sound, contamination-free substrate — skipping preparation defeats the whole system
• On its own the screed isn’t a finished wearing surface in heavily trafficked or dusty areas; most plants still add a hardener, sealer or resin topping over it
• Cold substrate or ambient temperature slows the rapid-set advantage, which is the entire reason for specifying it
• Results depend heavily on an experienced, MC-Bauchemie-briefed applicator; casual DIY mixing tends to under-deliver on the stated timelines

How we position MC-Bauchemie MC-Floor Screed

MC-Floor Screed sits alongside Space Arc’s other MC-Bauchemie flooring and repair lines — pair it with an MC-DUR resin coating or hardener where the repaired patch still needs a wearing surface, and with the Nafufill/Emcefix concrete-repair mortars where the damage runs into the structural slab rather than just the screed layer. For projects that call for a resin-based rather than cement-based rapid-floor solution, Fosroc’s Nitoflor epoxy and PU screed range — already in Space Arc’s catalogue — is a genuine alternative chemistry, but it isn’t a like-for-like substitute for MC-Floor Screed’s specific hours-not-weeks cementitious repair use case, so no single named Fosroc equivalent is listed here. The choice between the two comes down to priority: fastest possible return-to-traffic on a cement substrate (MC-Floor Screed) versus a monolithic resin wearing course (Nitoflor).
