Fosroc Nitobond EP

Fosroc Nitobond EP is a two-part, solvent-free epoxy bonding agent that keys fresh, plastic concrete or mortar to existing cementitious substrates, forming a high-strength, water-tight interface—even on permanently damp surfaces—making it ideal for both interior and exterior repairs and overlays.

Features + Benefits:

Structural Epoxy Bond: Delivers exceptional tensile and shear adhesion for monolithic performance between new and old concrete.
Damp-Tolerant Barrier: Bonds securely to saturated-surface-dry or wet substrates while acting as an impermeable moisture block.
Internal & External Durability: Resistant to water, chemicals, and weathering for versatile site use.
Solvent-Free, Low-Odour: Safer for enclosed pours and environmentally sensitive environments.
Easy 1:1 Mix Ratio: Pre-measured resin and hardener components ensure consistent on-site batching.

Product Uses:

Bonding structural toppings, screeds, and fresh repair mortars to existing slabs, beams, columns, and precast units;
Providing a substrate/repair barrier beneath Renderoc or other repair systems in wet zones (wastewater plants, marine structures, basements);
Securing patch repairs on bridge decks, pavements, and industrial floors subject to vibration or heavy loads.

Pack Size:

Supplied in colour-coded simply mix Part A 1L (resin) with Part B 500ml (hardener) until uniform.
