MC-Bauchemie MC-DUR 1000 Parat 04
A pigmented two-component epoxy resin mortar from MC-Bauchemie built for fast, shrinkage-free repair of holes, cracks and post foundations on hard-wearing concrete floors.
What is it?
A pigmented, two-component (Comp A resin + Comp B hardener) epoxy resin repair mortar from MC-Bauchemie’s MC-DUR floor system, sold in India as MC-DUR 1000 Parat 04.
Where is it used?
Horizontal concrete surfaces that see traffic and abrasion — industrial and parking floors, loading areas, kerbs and the concrete around railing and guard-rail post foundations.
Why use it?
It cures almost shrinkage-free to very high strength (roughly 98 N/mm² compressive at 7 days), is impervious to liquids and resists frost and de-icing salts, so a patch outlasts the surrounding slab.
How is it applied?
Blend the two components at 100:3.3 by weight, trowel into a clean, primed cavity within the ~50-minute pot life, and compact; the patch takes foot traffic in about 12 hours at 20 C.
About MC-Bauchemie MC-DUR 1000 Parat 04
MC-DUR 1000 Parat 04 is the epoxy repair mortar in MC-Bauchemie’s MC-DUR floor-protection family, and despite the “1000” tag it is a reinstatement material rather than a coating. It arrives as two pre-weighed parts — a pigmented epoxy resin base and a hardener — that are combined on site at a fixed 100:3.3 ratio by weight. Once mixed and placed, it cures to a dense, softener-free mortar that is essentially shrinkage-free and impervious to liquids, which is exactly what a horizontal patch on a working floor needs: it will not dish, crack away from the parent concrete, or wick moisture the way a poorly matched cementitious filler can.
For Indian projects the appeal is durability under punishment. The cured mortar reaches roughly 85 N/mm² compressive strength within 24 hours and around 98 N/mm² after seven days, with flexural strength near 35 to 38 N/mm² — figures well above ordinary structural concrete. It stays stable across a wide service range of about −40 C to +80 C and shrugs off frost and de-icing salt exposure. That makes it a natural fit for repairing spalled bays in industrial sheds, filling out worn kerbs and edges, levelling potholes in trafficked slabs, and anchoring the concrete pockets that hold railing and guard-rail posts on decks and ramps.
The technical insight
The performance comes from epoxy chemistry doing something a cement patch cannot. When Component A (resin) and Component B (hardener) are mixed at 100:3.3, the two react and cross-link into a continuous thermoset matrix that binds the graded aggregate — there is no free water in the system to evaporate, so the mortar cures almost shrinkage-free and stays bonded to the cavity walls instead of pulling in on itself. That same dense, pore-free network is what makes it impervious to liquids and resistant to frost and de-icing salts: there is little open porosity for water, chloride or fuel to enter. The trade-off is that the reaction is temperature-driven and time-limited. Warmth speeds it up and cold slows it down, so MC-Bauchemie specifies application between about 10 C and 30 C with the substrate kept at least 3 K above the dew point to stop a moisture film sabotaging the bond. The workable pot life is roughly 50 minutes at 20 C — mix only what a crew can place and compact inside that window, because once gelling starts the material can no longer be worked.
Where it is used
- Levelling out holes, potholes and spalled patches in horizontal concrete floors
- Filling and repairing cracks in trafficked slabs and industrial floors
- Filling-in and reinstating railing-post and guard-rail-post foundation pockets
- Stabilising and re-anchoring railing, balustrade and guard-rail posts
- Rebuilding worn or damaged kerbs, edges and slab arrises
- Patch repair of loading bays, ramps and parking decks subject to abrasion
- Reinstatement of concrete around fixings and embedded steel on horizontal surfaces
Key advantages
- Very high strength — around 85 N/mm² compressive at 24 h rising to roughly 98 N/mm², so patches outlast the parent slab
- Cures almost shrinkage-free, avoiding the dishing and edge cracking common with cementitious fillers
- Impervious to liquids, keeping water, fuels and chlorides out of the repair
- Frost and de-icing-salt resistant, suiting exposed decks, ramps and external kerbs
- Broad service-temperature stability from about −40 C to +80 C
- Softener-free formulation for long-term dimensional stability
- Rapid return to service — foot-traffic-ready in roughly 12 hours at 20 C
- Pigmented finish blends the repair visually rather than leaving a raw grey scar
Limitations & considerations
- Formulated for horizontal surfaces — not a vertical or overhead patching mortar
- Short working window of about 50 minutes at 20 C, so batches must be sized to what the crew can place
- Sensitive to conditions: needs 10-30 C and the substrate at least 3 K above dew point, ruling out damp or cold-weather placement without control
- Two-component material that must be mixed at the exact 100:3.3 weight ratio — no eyeballing on site
- Epoxy colour can shade or chalk under prolonged UV, a cosmetic effect that does not reduce strength or imperviousness
- A higher-cost, engineered repair — best reserved for load-bearing and durability-critical patches rather than large cosmetic areas
Selection & best practice
Success is almost entirely about preparation and timing. Break out all loose, cracked or contaminated concrete back to a sound edge, then mechanically prepare the cavity — grit-blast, scabble or grind — to expose clean aggregate and give the epoxy something to key into; remove all dust, oil, laitance and standing water. Prime the prepared surface with the compatible MC-DUR epoxy primer while it is still tacky so the mortar bonds wet-on-tacky. Combine the full pre-weighed units of Component A and B at 100:3.3 by weight and mix with a slow-speed paddle until uniform in colour, scraping the sides so no unmixed streaks remain. Place and firmly compact the mortar into the cavity within the ~50-minute pot life, working it against the primed edges to eliminate voids, and finish level. Keep material, substrate and air between 10 C and 30 C with the slab at least 3 K above the dew point throughout. Protect the fresh repair from water and traffic — foot traffic after about 12 hours at 20 C, with full mechanical and chemical loading held back for around 7 days.

How we position MC-Bauchemie MC-DUR 1000 Parat 04
MC-DUR 1000 Parat 04 sits in the reinstatement corner of MC-Bauchemie’s MC-DUR floor system, so it pairs naturally with the rest of that family: an MC-DUR epoxy primer beneath the patch for bond, and MC-DUR resin coatings or screeds over the wider floor once repairs are done. Where the damage is a thin surface defect rather than a deep cavity, a resin sealer is the better tool than a mortar. From our other brand lines, Space Arc can also supply Fosroc’s Nitomortar and Renderoc repair ranges and Sika’s Sikadur / SikaTop repair mortars where a project standard or a vertical-repair requirement calls for them. Talk to our technical team and we will match the mortar to the geometry, loading and exposure rather than defaulting to one product.
