MC-Crete 710
Liquid Concrete Surface Hardener and Dustproofer for Industrial Concrete Floors
Authorized Project Distributor — MC-Bauchemie India | Space Arc Engineering, Ghaziabad
Product Overview
MC-Crete 710 is a ready-to-use liquid silicate penetrating concrete surface hardener and densifier manufactured by MC-Bauchemie for the chemical hardening and dust-proofing of concrete floor surfaces. The product is a colloidal silica or alkali metal silicate solution that penetrates the pore structure of the concrete surface and reacts with the calcium hydroxide (Ca(OH)2) produced during cement hydration — a byproduct that is inherently soft, soluble, and responsible for the surface dusting and poor abrasion resistance of concrete floors — to form additional calcium silicate hydrate (C-S-H) gel. This reaction, chemically similar to the pozzolanic reaction that occurs in fly ash and GGBFS blended concrete, densifies the pore structure of the concrete surface zone (the top 3 to 10 mm of the slab), reducing the porosity, increasing the surface hardness, and eliminating the friable calcium hydroxide-rich laitance layer that causes dusting. The concrete dusting problem in Indian factories and warehouses — where a thin layer of fine grey powder appears on the floor surface and is continuously tracked through the facility on footwear and vehicles — is both a housekeeping problem (the dust soils products, machinery, and clean environments) and a safety problem (fine concrete dust contains crystalline silica which presents a respiratory hazard on prolonged inhalation). MC-Crete 710 eliminates dusting by chemically converting the surface laitance into a hard, dense calcium silicate hydrate matrix that is bound to the underlying concrete and does not powder under traffic. The product is applied by roller or sprayer to the dry or slightly damp concrete surface in 1 to 2 applications, penetrates by gravity and capillary suction, and does not form a visible surface film — the treated concrete retains its natural appearance. Space Arc Engineering supplies MC-Crete 710 for factory builders, warehouse developers, and industrial facility maintenance contractors throughout Delhi NCR, Ghaziabad, Noida, and Uttar Pradesh.
Applications
- New industrial concrete floor slab hardening — eliminate surface dusting before commissioning a factory or warehouse
- Existing concrete floor dustproofing — remedial treatment of dusting warehouse and factory floors
- Car park and logistics hub floor surface hardening — reduce forklift wheel abrasion and concrete dust
- Food processing facility concrete floor treatment — eliminate concrete dust contamination of food products
- Precast concrete surface treatment — harden precast element surfaces for improved durability
- Maintenance of hardened concrete floors — periodic re-application to maintain dust-free surface condition
Key Advantages
- Eliminates concrete dusting permanently — chemical hardening converts friable laitance into dense C-S-H matrix
- Penetrating — invisible treatment — no surface film — no change to floor level or traction properties
- Increases surface abrasion resistance — harder, denser surface withstands forklift and trolley traffic longer
- Simple roller or spray application — fast programme for large floor areas — no specialist equipment needed
- Non-toxic — silicate-based — safe for food processing and pharmaceutical facility floors after drying
- Cost-effective — low material and labour cost versus any alternative floor topping or coating system

Frequently Asked Questions
For an existing 10,000 square metre warehouse floor in a Ghaziabad logistics park that has developed severe concrete dusting after 3 years of forklift traffic, what is the correct diagnosis and treatment sequence using MC-Crete 710, and what should be done about areas where dusting is so advanced that the concrete surface has actually worn away?
Severe concrete dusting and surface wear in an operational logistics warehouse in Ghaziabad — a facility that is almost certainly running two or three shifts per day with heavy electric forklift traffic — is one of the most common and commercially urgent flooring problems in Delhi NCR industrial real estate. The economic consequences of concrete dusting are substantial: the fine concrete dust contaminates stored goods and their packaging; it is tracked into office and welfare areas by forklift operators; in food and pharmaceutical logistics facilities it creates product contamination risk; and the dust constitutes a respiratory health hazard for warehouse operatives. Before specifying the treatment, a correct diagnosis of the severity and extent of the problem is essential, as the appropriate solution changes significantly depending on whether the floor is in the early dusting stage or the advanced surface erosion stage. Diagnosis stage 1 — severity assessment. Walk the floor systematically in good lighting (preferably low-angle raking light from a temporary LED floodlight) and classify the floor into three zones. Zone A — early stage dusting: the surface is intact (no visible aggregate exposed) but produces fine grey dust when rubbed with a dry hand. This zone responds well to MC-Crete 710 silicate hardener treatment. Zone B — intermediate stage: the surface is worn and the fine aggregate (sand-size particles) is beginning to be visible at the surface, and there are light wheel marks from forklift tyres. This zone requires preparation (mechanical grinding or scabbling to remove the weak surface layer) before MC-Crete 710 application. Zone C — advanced erosion: the coarse aggregate is visible at the surface, the slab is pitted and uneven, and there are visible tyre track grooves. This zone has lost 3 to 10 mm of surface depth and cannot be effectively treated with silicate hardener alone — it requires a cementitious floor topping (MC-Floor 13 polymer-modified floor screed or equivalent) applied at 10 to 20 mm thickness to reinstate a wearing surface before the hardener treatment. Diagnosis stage 2 — cause identification. Understanding why the floor dusted is important for specifying the correct fix and preventing recurrence. In most Ghaziabad warehouses built in the 2010s and 2020s, floor dusting is caused by one or more of the following: excessive water-cement ratio at placing (the contractor added water to the ready-mix drum on site to improve workability — this concentrates the weak laitance at the surface); inadequate curing (the concrete slab in the Indian climate dries out rapidly in hot weather — insufficient curing produces a weak, high-porosity surface zone); bleed water finishing (the surface was finished too early, working bleed water into the surface layer and further raising the surface water-cement ratio); or inadequate specification of the concrete surface finish (no power-floating, inadequate steel trowelling). Treatment sequence. For Zone A and Zone B floors (early to intermediate dusting, no significant aggregate exposure), the treatment is as follows. First, vacuum clean the entire floor surface to remove all dust, dirt, and loose material. For Zone B areas, run a rotary floor grinder (single-disc or ride-on depending on area size) with a medium-grit diamond disc (40 to 60 grit) to grind the surface by 1 to 2 mm, removing the weakest surface layer and opening the pores for MC-Crete 710 penetration. Vacuum after grinding. Apply the first coat of MC-Crete 710 by roller or low-pressure pump sprayer (back-and-forth in one direction, working in bays of approximately 50 to 100 square metres) at 200 to 250 ml per square metre. Apply slowly enough for the silicate solution to be absorbed by the concrete — if the surface puddles rather than absorbing, reduce the application rate and allow more time between passes. Allow the first coat to penetrate and dry for 4 to 6 hours. Apply the second coat perpendicular to the first at 150 to 200 ml per square metre. Allow to dry for 24 hours. Clean the surface with a neutral-pH floor cleaner and auto-scrubber. For Zone C floors (advanced erosion with exposed coarse aggregate and significant depth loss), apply MC-Floor 13 polymer-modified cementitious floor topping at 10 to 20 mm thickness over the prepared (scabbled and primed with MC-Dur 1225) Zone C areas before the MC-Crete 710 hardener treatment. Allow MC-Floor 13 to cure for 28 days before applying MC-Crete 710 over the full floor area.
