Nitomortar S
Three-Component Structural Grade Epoxy Repair Mortar for Concrete
Authorized Project Distributor — Fosroc India | Space Arc Engineering, Ghaziabad
Product Overview
Nitomortar S is a three-component, solvent-free, structural grade epoxy repair mortar consisting of an epoxy resin base, hardener, and graded aggregate filler. When mixed, the three components produce a stiff, trowellable mortar with very high compressive and flexural strength, excellent adhesion to primed concrete, and good resistance to chemicals, oils, and fuels. Unlike cementitious repair mortars, epoxy mortars are not porous and therefore provide a chemically resistant repair for industrial floors, chemical plant concrete, and areas where the repaired surface will be in contact with aggressive liquids. Nitomortar S is used for deep profile repair of deteriorated industrial concrete floors, repairing broken edges and arrises on concrete structures, filling cavities and recesses in concrete, and reinstatement of concrete in areas where superior chemical resistance or very high strength in a thin section is required. It is compatible with Nitobond EP epoxy bonding primer for maximum adhesion to the prepared concrete substrate. Space Arc Engineering distributes Nitomortar S for industrial concrete repair and floor repair projects across Delhi NCR, Ghaziabad, and Northern India.
Applications
- Deep profile repair of deteriorated industrial concrete floors
- Edge and arris repair of columns, beams, and slab edges
- Chemical and oil resistant concrete floor surface repair
- Repair of chemical plant and process floor damaged concrete
- Reinstatement of concrete surfaces subject to chemical attack
- High strength thin section repair where cementitious mortars have insufficient strength
Key Advantages
- Very high compressive strength — over 80 MPa at 28 days

Frequently Asked Questions
How does Nitomortar S differ from Renderoc S2 cementitious repair mortar?
Renderoc S2 is a cementitious (cement-based) repair mortar suitable for structural concrete reinstatement where chemical resistance is not a primary requirement and the repair will not be in immersed or aggressive chemical conditions. Nitomortar S is an epoxy mortar providing very high compressive strength and good resistance to chemicals, oils, and fuels. Epoxy mortars are more expensive than cementitious mortars and are specified when the repair is in a chemically aggressive environment, when very high strength in a thin section is required, or when the surface will be in contact with liquids that would attack cementitious materials.
Does Nitomortar S need to be applied in layers for deep repairs?
Nitomortar S can be applied in layers of 5 to 50 mm per lift, depending on the repair geometry. For deeper repairs, apply in staged lifts, allowing each lift to reach its initial set before applying the next. In very deep repairs, the significant exothermic heat generated by thick epoxy lifts should be managed by applying thinner lifts and allowing cooling between layers. Consult Space Arc Engineering for guidance on the maximum lift thickness for large-volume epoxy mortar applications.
What surface preparation is needed before applying Nitomortar S?
The concrete substrate must be mechanically prepared by grit blasting, scarifying, or grinding to remove all weak, contaminated, or laitance-covered concrete and achieve a clean, rough, sound surface profile. Contamination by oil, fuel, or grease must be fully removed by solvent washing and then mechanical preparation before applying Nitobond EP primer. Nitomortar S must be applied to the fresh Nitobond EP primer while still in the green tacky state for maximum adhesion.
