Fosroc Nitomortar S — Solvent-Free Epoxy Repair Mortar for Structural Concrete Repair (10 Ltr)

Epoxy repair mortars containing solvents present a practical problem in many repair environments. In confined spaces — tunnels, basement structures, underground car parks, enclosed industrial facilities — solvent vapours accumulate rapidly, creating health hazards for applicators and potential ignition risks in spaces where ventilation is limited or where flammable materials are present. Even in open environments, solvent-based systems require extended airing time before the repaired space can be reoccupied or the repaired surface brought back into service. For repair work in occupied or sensitive environments, solvent-free is not a preference — it is a requirement.

Fosroc Nitomortar S is a solvent-free epoxy repair mortar engineered for structural concrete repair in environments where solvent emissions are unacceptable. The solvent-free formulation eliminates the vapour and odour issues associated with solvent-containing epoxy systems — making it safe for application in confined spaces, occupied buildings, food processing facilities, water treatment structures, and any repair environment where ventilation is restricted or where solvent exposure to occupants or products cannot be tolerated.

Despite the solvent-free formulation, Nitomortar S delivers the full structural performance of an epoxy repair system — high compressive and tensile bond strength to prepared concrete and steel substrates, chemical resistance to a broad range of aggressive substances, and a dense impermeable cured matrix that provides durable long-term protection of the repaired section against moisture, carbonation and chemical attack.

The trowel-applied consistency makes it suitable for horizontal, vertical and overhead structural repairs — restoring spalled sections, repairing damaged edges and bearing surfaces, and rebuilding concrete elements in environments where standard solvent-containing epoxy mortars cannot be safely used.

A construction chemical repair solution from Fosroc for structural epoxy repair in sensitive and confined environments — Nitomortar S is the solvent-free epoxy repair mortar specification for applications where safety and structural performance must both be delivered.
