MC-Bauchemie MC-Top 100
A dry-shake quartz hardener that fuses into fresh concrete, giving warehouse and factory floors a dense, dust-free wearing surface for life.
What is it?
MC-Top 100 is MC-Bauchemie’s factory-blended dry-shake floor hardener — graded silica-quartz aggregate (Mohs hardness around 7) in a hydraulic cement binder — broadcast onto fresh concrete and trowelled into the surface.
Where is it used?
Warehouses, factories, parking decks, workshops, loading docks, cold stores and institutional floors across India that see constant forklift and trolley traffic.
Why use it?
Plain concrete dusts and wears under repeated wheel traffic within a few years. MC-Top 100 raises surface hardness sharply, and goes on during the concrete pour itself — no extra construction stage.
How is it applied?
Broadcast dry in two passes once bleed water has gone but before the slab stiffens, then floated, power-trowelled and cured like the rest of the floor.
About MC-Bauchemie MC-Top 100
Every industrial floor meets the same enemy — repeated wheel traffic. Ordinary concrete has a cement-paste surface too soft to survive years of forklifts and trolleys; it dusts, pits and wears through. MC-Top 100 tackles this at the source: a factory-blended dry-shake hardener — graded silica-quartz aggregate in a hydraulic cement binder — broadcast onto the freshly placed slab and worked in before it sets. Because it becomes part of the same pour, there’s no interface and no separate topping that can later debond or curl.
Floated and power-trowelled home, it leaves a dense, quartz-rich wearing skin about 2–3mm deep. MC-Bauchemie rates surface strength around 60 N/mm² nominal, up to 80 N/mm², with Böhme Class A6 abrasion resistance. Dosage is matched to traffic — 3–5 kg/m² for light duty up to 7–8 kg/m² where forklifts run all day. It ships in 25kg moisture-resistant bags, in natural grey or decorative colours, so the performance grade doesn’t mean giving up on appearance.
The technical insight
The gain comes from two things happening together. Quartz sits around 7 on the Mohs scale — several times harder than the hydrated cement paste at an untreated slab’s surface — so packing graded 0–1.4mm quartz into that zone directly raises wear resistance. Just as important is timing: the hardener goes onto concrete that hasn’t stiffened, so its cement binder hydrates together with the parent slab’s own paste, curing as one continuous matrix rather than two bonded layers. That’s why there’s no interface for impact or thermal movement to open up later, and why broadcast timing matters more here than with almost any other flooring material.
Where it is used
- Warehouse and distribution-centre floors under constant forklift traffic
- Factory and production-floor slabs in manufacturing plants
- Multi-level and basement parking decks and ramps
- Workshops, service bays and vehicle maintenance floors
- Loading docks and goods-handling platforms
- Cold storage and freezer-room floors
- Institutional and commercial back-of-house floors — kitchens, stores, plant rooms
- Assembly and light-engineering floors needing a dust-free surface
Key advantages
- Bonds monolithically with the slab — no separate topping to debond or curl
- Cuts surface dusting sharply from day one
- Applied in the same pour, adding no extra stage to the programme
- Surface strength up to 80 N/mm², well beyond plain concrete
- Böhme Class A6 / BCA AR1 abrasion resistance for years of traffic
- Factory-controlled quartz grading gives consistent results pour to pour
- Extends floor life, cutting lifecycle resurfacing costs
- Grey or decorative colour options without changing performance
Limitations & considerations
- Non-metallic quartz isn’t right for extreme impact — steel-handling or forging floors need a metallic hardener
- Timing-critical: needs an experienced crew and the right weather window
- Can’t compensate for a poor concrete mix or bad compaction
- Not suitable for floors regularly exposed to acids or aggressive chemicals
- Bonds only to fresh concrete — can’t be retrofitted onto an existing floor
- Skipping the post-finish curing compound risks shrinkage cracking
Selection & best practice
Start with the base concrete — a well-compacted M25-grade-or-above mix with a controlled water-cement ratio; the hardener sharpens a good slab, it can’t rescue a weak one. Broadcast in two passes once bleed water has evaporated but before the concrete stiffens: float the first pass in, broadcast the second at right angles for even coverage, then power-float and trowel both in together. Match dosage to actual traffic rather than defaulting low. Cut control joints once the surface takes light foot traffic, and apply a curing compound immediately after finishing — this one step prevents most shrinkage cracking. Keep the crew experienced, since the process happens in a narrow window on curing concrete.

Industry use cases
Warehousing & logistics
3PL and e-commerce floors where forklifts and pallet trucks run all day need a surface that won’t dust into the stock.
Manufacturing
Production floors in light and medium engineering plants, for a dust-free surface around machinery and assembly lines.
Parking infrastructure
Multi-level and basement decks, where the monolithic bond avoids delamination that toppings suffer under traffic and thermal cycling.
Cold chain & food processing
Cold storage and freezer floors, where a hard, low-dust surface must perform for years under wheeled traffic at sub-zero temperatures.
Institutional & commercial
Back-of-house areas — kitchens, loading bays, plant rooms — where durability matters more than decorative finish.

How we position MC-Bauchemie MC-Top 100
MC-Top 100 covers general industrial and institutional traffic well, but it’s one part of a bigger specification. For extreme impact or point loads — steel yards, forging bays, heavy machine shops — MC-Bauchemie’s metallic-aggregate hardener grades are the right upgrade. For a fully sealed, chemical- and stain-resistant finish instead of an open dry-shake surface, Space Arc also carries Fosroc’s Nitoflor epoxy coating range. And since a dry-shake floor is only as good as the joints around it, we typically pair MC-Top 100 with MC-Bauchemie’s own curing compounds and joint sealants on the same pour.
Fosroc Fosroc Nitoflor Hardtop — Fosroc’s equivalent dry-shake floor hardener, offered in non-metallic and metallic/emery-aggregate grades — a straightforward swap on projects that call for a Fosroc system or need the extra impact resistance of a metallic grade.
