    FOS7921

    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.

    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
    • Grit-blasting is recommended for this process

    Reinforcing Steel Priming

    • The cleaned steel should be coated within 3 hours
    • Apply one full coat of Nitoprime Zincrich Plus and allow to dry before continuing
    • 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
