Fosroc Nitomortar S is a solvent-free high strength, abrasion-resistant epoxy reinstatement mortar.
Suitable for use for the fast and permanent reinstatement of concrete, particularly where high strength, abrasion-resistance and resistance to chemicals is required. The product is designed for horizontal use but can be applied vertically, although generally in thinner sections.
It is ideally suited for acid tanks, sea walls, industrial floors and for use as a bedding mortar. Nitomortar S can be used for emergency repairs where fast strength gain is important.
Three-component material supplied in pre-weighed quantities ready for on-site mixing and use
Available in 'Standard' (5kg) and 'Industrial' 16kg packs
High ultimate strength — suitable for structural use
Early development of strength minimises disruption
Abrasion-resistance — suitable for heavily trafficked areas
Highly resistant to a wide range of chemicals
Cured product is highly impermeable to water when ‘tight trowel’ finished
Typically twice as strong as good quality concrete
Pre-weighed components ensure consistency
Based on a high quality solvent-free epoxy resin system
Special silica aggregates provide high strength and excellent abrasion resistance
In certain instances, Nitomortar S can be used on metal substrates. Please contact our Technical Department on 0113 2455450 (option 2) or send a message to [email protected] for details
For fast repairs in vertical and overhead locations where a higher-build, lightweight formulation is required, the use of Nitomortar HB is recommended
Complies with EN1504-3: Structural and non-structural repair methods 3, 4 and 7
Nitomortar S is non-flammable

Application Notes
Preparation
Clean the surface and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits or algae
Roughen the surface and remove any laitance by light scabbling or grit-blasting. Saw cut or cut back the extremities of the repair locations to a depth of at least 5 mm to avoid feather-edging and to provide a square edge
Break out the complete repair area to a minimum depth of 5mm up to the sawn edge
Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser
The effectiveness of decontamination should then be assessed by a pull-off test
Expose fully any corroded steel in the repair area and remove all loose scale and corrosion deposits
Steel should be cleaned to a bright condition paying particular attention to the back of exposed steel bars
If any doubt exists about having achieved an unbroken coating, a second application should be made and, again, allowed to dry before continuing
Substrate Priming
Horizontal or damp substrates should be primed using Nitoprime 25
Predominantly vertical and metal substrates should be primed using Nitoprime 28
In both cases, the primer should be mixed in the proportions supplied, adding the entire contents of the ‘hardener’ tin to the ‘base’ tin
The two components should be thoroughly mixed for 3 minutes
If the primer is absorbed within 30 minutes, a second coat should be applied before continuing
Mixing
‘Standard’ (5kg) packs may be mixed by hand
‘Industrial’ (16kg) packs must be mixed mechanically
Under no circumstances should part packs be used
Application
Apply the mixed Nitomortar S to the prepared substrate by wood float, pressing firmly into place to ensure positive adhesion and full compaction
Thoroughly compact the mortar around any exposed reinforcement. In restricted locations, or where exposed reinforcing steel is present, application by gloved hands is an acceptable alternative but, in all cases, the product must be finished to a tight surface with a steel trowel.
Nitomortar S can be applied in sections up to 50 mm thickness in horizontal locations or up to 6 mm thickness in vertical locations in a single application and without the use of formwork
When larger areas are being rendered, a chequerboard application technique is recommended
Note: the minimum applied thickness of Nitomortar S is 5 mm
Please see the Product Data Sheet for detailed information on all of the above.
Limitations
Should not be used when the temperature is below 5°C and falling
Do not mix part packs under any circumstances
Should not be used in overhead locations — use Nitomortar HB for this purpose
Should not be exposed to moving water during application
Exposure to heavy rainfall prior to the final set will result in surface softening and scour
Nitoprime 28 is not a damp tolerant primer
