Nitomortar mortars are two pack epoxy resin mortars. Each part is a different colour to provide visual
confirmation of adequate mixing on site. Nitomortar cures chemically and therefore does not require the presence of water, solvent or oxygen.
Nitomortar products have high comprehensive strengths, cure with negligible shrinkage and are resistant to chemical and physical attack. After 48 hours at 20 derajat C Nitomortar compounds will have achieved between 60 to 70% of their final compressive strength.
Uses
- General Purpose Applications
Nitomortar GP is a versatile low slump material used for general repair work. Typical applications include patching spalled or honeycombed vertical surfaces, protecting exposed reinforcement, reinstating damaged arrises and repairing damaged precast concrete building units.
- Bedding Applications
Nitomortar BC is designed for bedding applications and can be trowelled to a fine accurate surface. Applications include bedding concrete kerbs to concrete, bedding bridge bearing pads and mounting heavy plant and equipment.
- Underwater Application
Nitomortar UA is formulated for use in exceptionally wet conditions and underwater applications. Nitomortar UA is recommended for reinstating structures exposed to the heavy battery of the sea (e.g.: sea walls) for repairing submerged steelwork or concrete (particularly exposed reinforcement) and for fixing slip bricks, tiles and tiles pointings.
