MC-Bauchemie MC-Crete 710
A penetrating silicate hardener that reacts inside the slab to lock down dusting, lift abrasion resistance and leave the concrete looking exactly as it did.
What is it?
A colourless, water-thin silicate solution that soaks into cured concrete and reacts chemically to densify the surface, hardening the floor and stopping it shedding fine dust.
Where is it used?
Warehouse and factory slabs, logistics and distribution hubs, multi-level car parks, food-processing floors and precast surfaces across Delhi NCR and pan-India.
Why use it?
It cures chronic concrete dusting at the source instead of hiding it under a film, so forklift and foot traffic stops kicking up powder and the slab wears far more slowly.
How is it applied?
Flood-applied by roller or low-pressure sprayer onto clean, cured concrete in one or two coats, worked until the surface stops absorbing, then any surplus is spread off before it dries.
About MC-Bauchemie MC-Crete 710
MC-Crete 710 is MC-Bauchemie’s answer to one of the most persistent complaints on an industrial floor: a slab that never stops giving off fine grey powder. It is a penetrating silicate treatment, not a coating. The liquid is thin enough to be drawn deep into the capillary structure of the concrete, where it does its work chemically rather than sitting on top as a wearing layer. Because there is no film, there is nothing to peel, chalk or delaminate under wheel traffic, and the floor keeps its original bare-concrete look.
For engineers and facility managers, that combination is what makes it attractive. A dry-shake topping has to go down with the fresh pour and a resin system needs surface preparation, primer and a controlled cure window. MC-Crete 710 can be brought onto a floor that is already in service, applied over a weekend with basic tools, and put back into use quickly. Space Arc Engineering supplies and applies it as an authorised MC-Bauchemie partner, which means the same team that specifies the dosage for your substrate can also carry out the application and stand behind the result.
The technical insight
The chemistry is the whole story here. Cured concrete always carries a reservoir of free calcium hydroxide left over from cement hydration, and it is this soft, soluble material near the surface that breaks down into dust under abrasion. When MC-Crete 710 penetrates the slab, its reactive silicate seeks out that calcium hydroxide and converts it into calcium silicate hydrate (C-S-H) gel, the same dense binder phase that gives concrete its strength in the first place. It is essentially a controlled, in-situ pozzolanic reaction, closely related to what fly ash or GGBFS does inside blended concrete. The new C-S-H fills the fine pore network right at the surface, so the top few millimetres become tighter, harder and far less permeable. The reason a second coat matters is simple: the reaction is limited by how much silicate the pores can pull in per pass, so on hungrier or older slabs a follow-up application lets the treatment keep building density until the surface refuses to take any more.
Where it is used
- Hardening and dustproofing new industrial floor slabs once they have reached adequate age
- Remedial treatment of existing warehouse and factory floors that have started to dust
- Surface densification of car park decks and logistics-hub floors under constant tyre traffic
- Treating food-processing and packaging floors where airborne concrete dust is unacceptable
- Surface treatment and dustproofing of precast concrete elements
- Routine maintenance re-treatment of previously hardened floors that are beginning to wear
Key advantages
- Attacks concrete dusting at its chemical root rather than masking it with a temporary film
- Leaves no surface coating, so there is nothing to peel, blister or wear through under forklifts
- Keeps the concrete’s natural grey appearance, with only a slight sheen if the floor is later polished
- Applied quickly with a roller or sprayer and simple labour, with minimal downtime for the facility
- Can be applied to floors already in service, not just fresh pours
- Non-film, silicate-based formulation that raises surface abrasion resistance as it densifies
- Cost-effective compared with dry-shake toppings or full resin flooring systems
Limitations & considerations
- It densifies and dustproofs, but it is not a decorative or high-build wearing layer; heavily impact-loaded floors may still need a topping or resin system
- The finish stays natural concrete grey, so it will not hide existing stains, patchiness or repairs
- Performance depends on the concrete having enough free lime and open capillaries to react with; very dense, over-trowelled or previously sealed surfaces absorb less and gain less
- It cannot repair cracks, spalls or structural defects, and these should be dealt with before treatment
- New concrete must be adequately cured and aged before application; treating a green slab wastes product and gives poor results
- Any surplus that is allowed to dry on the surface can leave a residue and must be worked off during application
Selection & best practice
Start with a genuinely clean, sound and dry-to-slightly-damp surface. Sweep and, where needed, scrub off dirt, curing compounds, oil and laitance, because anything sitting on the concrete blocks penetration. New floors should be allowed to cure and age before treatment; as a working guide, allow around 28 days for fresh concrete, while existing floors of any age are fine. Flood the surface evenly with roller or low-pressure spray at roughly 150 to 250 ml per square metre per coat and keep working the liquid so the concrete stays wet and absorbing rather than pooling. Once the surface has taken all it will and any excess has been spread out to avoid a dried residue, judge whether a second coat is needed: hungrier or older slabs usually benefit, applied after the first coat has soaked in and dried. Protect fresh treatment from foot and wheel traffic while it reacts. As dosage, coat count and cure times vary with substrate porosity and site conditions, confirm the exact specification with Space Arc’s technical team and refer to the current MC-Bauchemie data sheet.

Industry use cases
Warehousing & logistics
Large distribution and storage slabs that dust under constant forklift and pallet-truck movement get a harder, lower-maintenance surface without closing the shed for a resin job.
Multi-level car parks
Deck surfaces under continuous tyre traffic are densified so they resist abrasion and stop shedding powder onto vehicles below.
Food processing & packaging
Production and packing floors where airborne concrete dust would be a contamination risk are dustproofed while keeping a plain, wipe-clean concrete finish.
Precast & manufacturing
Precast yards and factory floors use it to harden and seal exposed concrete surfaces against day-to-day wear and dusting.

How we position MC-Bauchemie MC-Crete 710
MC-Crete 710 sits in Space Arc’s industrial-flooring range as the penetrating, no-film option for hardening and dustproofing existing or newly cured concrete, alongside MC-Bauchemie’s MC-DUR resin floor coatings and non-metallic dry-shake floor hardeners for jobs that need a built-up wearing layer or a decorative finish. Where a client wants a comparable fluorosilicate hardener, Fosroc’s Nitoflor Lithurin family is a genuine alternative we also supply, and for full resin build-ups Fosroc Nitoflor and Sika’s Sikafloor systems cover the heavier-duty end. Our technical team can help you decide between a reactive densifier like this and a topping or coating based on your traffic, downtime window and finish requirements.
Fosroc Nitoflor Lithurin — Choose the Fosroc Nitoflor Lithurin family when a specification calls for a proven fluorosilicate hardener-densifier or when the wider Fosroc flooring system is already being used on the project.
