Product Overview

MC-Floor IC is a penetrating reactive lithium silicate densifier and hardener from MC-Bauchemie representing the chemical hardener technology class for industrial concrete floor improvement. The working mechanism is a pozzolanic reaction within the concrete surface: lithium silicate solution (Li2SiO3 or Li2Si2O5) penetrates the concrete surface pore system and reacts with the calcium hydroxide (Ca(OH)2 — portlandite) that is a by-product of Portland cement hydration and is present in the concrete pore solution; the reaction produces additional calcium silicate hydrate (CSH) gel — the same material that is the primary binding phase in Portland cement — which fills the pores and microcracks in the concrete surface zone, increasing density, hardness, and surface strength. The lithium silicate is chosen over the older sodium silicate and potassium silicate densifiers for three technical advantages: lower risk of alkali-silica reaction (ASR) contribution — lithium ions are known ASR inhibitors and do not contribute to the alkali budget that drives ASR in aggregate-sensitive concretes; smaller lithium ion size enables deeper penetration into fine concrete pores; lower pH of the lithium silicate solution reduces the surface residue (silica gel deposit) often seen with sodium silicate over-application. MC-Floor IC applied to a new concrete floor after sufficient curing (minimum 28 days, ideally 60 days to ensure the concrete has developed the portlandite reservoir that the densifier reacts with) produces a surface with: significantly increased Mohs hardness at the surface (from a typical 5 to 6 for plain concrete to 7 to 8 after densification); reduced surface porosity and increased water resistance; the ability to be mechanically polished using diamond grinding equipment to produce a polished concrete floor finish; and permanent elimination of the concrete dusting problem that affects high-traffic industrial floors with inadequately hardened or insufficiently cured surface layers. Space Arc Engineering supplies MC-Floor IC for floor contractors, warehousing companies, and industrial facility developers across Ghaziabad, Delhi NCR, Noida, and Uttar Pradesh.

Applications

• New warehouse and logistics centre concrete floor treatment — application of MC-Floor IC to the power-trowelled, cured concrete floor slab in large logistics and e-commerce warehouses in the Delhi NCR corridor (Kundli-Manesar-Palwal KMP expressway industrial zone, NH-58 Ghaziabad logistics parks, Noida and Greater Noida industrial areas) — where the concrete floor is the primary asset in terms of forklift traffic, pallet racking loads, and forklift tyre wear, and where the densifier treatment converts the surface zone of the concrete slab into a hard, polishable, dust-free floor without the cost and maintenance burden of a separate epoxy or PU coating system over the entire floor area
• Existing concrete floor renovation in industrial facilities — retroactive application of MC-Floor IC to existing concrete floors in manufacturing plants, warehouses, and processing facilities where the original floor surface has developed a dust problem (concrete dusting is the breakdown of the weak, carbonated, laitance-rich surface layer under foot and vehicle traffic into fine concrete dust that contaminates products and requires frequent cleaning) — the reactive silicate densifier penetrates through the existing surface and reacts with the portlandite below the weak surface layer to harden the subsurface concrete, stopping dust generation without the floor closure time and surface preparation required for epoxy coating application
• Polished concrete floor system base preparation — application of MC-Floor IC as the densification stage in a polished concrete floor system, after initial diamond grinding to expose fresh aggregate and remove the weak surface laitance layer — the densifier is applied between grinding stages to harden the concrete surface and allow the subsequent finer diamond grinding passes to achieve a high-gloss mirror finish — the combination of densification and progressive diamond grinding produces the DCSM (Decorative Concrete Surface Market) polished concrete finish increasingly specified in commercial buildings, showrooms, and high-quality industrial facilities in Delhi NCR
• Cold storage and food processing facility floor hardening — reactive silicate densification of concrete floors in cold stores, food processing areas, and pharmaceutical manufacturing areas where the floor must be easily cleaned and chemically resistant, and where epoxy coatings may be impractical due to extreme temperature cycling (cold store floors at minus 25 degrees Celsius to ambient), wet processing conditions, or regulatory requirements for the flooring system chemical content — the treated concrete surface is chemically inert, does not support microbial growth, and is tolerant of cleaning chemical contact including alkaline degreaser and mild acid cleaning solutions
• Vehicle deck hardening in multi-storey car parks — MC-Floor IC application to the vehicle traffic deck concrete in multi-storey car parks to increase surface hardness and reduce tyre scuffing dust generation — in car parks, the combination of concrete dusting and tyre rubber deposit creates a pervasive grey dust accumulation that requires frequent high-pressure cleaning; densification reduces dust generation and makes the floor surface easier to clean

Key Advantages

• Permanent hardening — the reactive CSH gel formed by the lithium silicate — portlandite reaction is a permanent addition to the concrete matrix — it does not wear off or delaminate like surface coatings, and it becomes harder and denser over time as continued slow pozzolanic reaction within the concrete increases the CSH content further — a reactive silicate treatment is a permanent improvement to the concrete surface rather than a sacrificial surface coating that requires periodic replacement
• No delamination risk — unlike epoxy and polyurethane floor coatings that adhere to the concrete surface by adhesion and can delaminate if the adhesion bond fails (due to substrate moisture, impact, forklift outrigger loading, or thermal cycling), the lithium silicate densifier penetrates into and becomes part of the concrete substrate — there is no film to delaminate, no interlaminar weakness, and no risk of coating delamination during the service life of the floor
• Dust-proof treatment for dusty concrete floors — eliminates concrete dusting permanently by hardening the surface concrete zone — concrete dusting is caused by a combination of inadequate cement content or w/c ratio in the top surface (laitance formation), insufficient curing, and mechanical traffic wearing down the weak surface layer; the reactive silicate treatment hardens the subsurface concrete beneath the laitance layer, preventing continued dust generation even after the laitance layer is removed by initial traffic
• Improves surface water resistance and reduces water absorption — the increased CSH density in the surface zone reduces the capillary porosity and capillary absorption of water into the concrete surface — reducing both the water absorption rate and the total water absorbed by the floor surface under service conditions — relevant for food processing areas where the floor must resist absorption of food liquids, cleaning chemicals, and process water
• Compatible with polished concrete grinding — the lithium silicate-treated concrete surface can be mechanically polished using diamond grinding equipment (planetary grinder with diamond-impregnated segmented tooling) to produce a polished concrete floor with gloss levels from 400 grit (satin/matte) to 3000 grit (mirror polish) — the densification ensures the polished surface is hard enough to maintain the polish under foot and vehicle traffic without rapid re-dulling
