1. Nitomortar FC constructive solutions Fosroc Nitomortar FC Uses Nitomortar FC is designed for application to minor imperfec - tions in concrete surfaces. It is suitable for application from a feather-edge to 3 mm, and can be used in the following situations :  Filling pinholes prior to overcoating with Nitocote* † or Nitoflor* † products.  General reprofiling over large areas, up to 3 mm depth.  Sealing of surface cracks in preparation for crack injection.  General purpose bedding mortar and adhesive Advantages  Cost effective - reduces usage of subsequent coatings  High performance - excellent chemical resistance, strong adhesion to concrete substrate  User friendly - easy to apply and finish, manufactured to meet local conditions Description Nitomortar FC is a two component thixotropic, solvent free, compound based on epoxy resins, graded fillers and perfor - mance additives. It is applied directly to concrete substrates, without primer, and cures to a uniform smooth surface ready for over coating. Design criteria Nitomortar FC is designed for filling pinholes and surface irregularities in concrete prior to the application of subse - quent coatings. It can be applied from a feather-edge up to 3 mm thickness. For reprofiling, or hole filling, with thicknesses in excess of 3 mm, it is recommended to use Nitomortar FC(B)*. Technical support Fosroc offers a comprehensive technical support service to specifiers, end users and contractors. It is also able to offer on-site technical assistance, an AutoCAD facility and dedicated specification assistance in locations all over the world. Properties Solids by weight : 100% @ 25ºC Compressive strength : 70 N/mm 2 @ 7 days Pot life : 1 hour 40 mins @ 25ºC 1 hour @ 35ºC Drying time : 10 hours @ 25ºC 4 hours @ 35ºC Overcoating time : After 24 hour curing period Colour : Grey Chemical resistance : Resistant to oils, fats, petrol, salt and sugar solution, bleach, dilute mineral acids, alkalis and various solvents Instructions for use Preparation Concrete surfaces should be clean, dry and free from laitance. Sandblasting or mechanical wire brushing may be necessary. Mixing Care should be taken to ensure that Nitomortar FC is thoroughly mixed to produce a fully homogeneous paste. The hardener’ and ‘base’ components should be stirred thoroughly in order to disperse any settlement before mixing them together. The entire contents of the ‘hardener’ should be emptied into the ‘base’ container and the components mixed together using a Fosroc mixing paddle attached to a slow-speed (400/500rpm) heavy duty drill, until a uniform grey colour and consistency is obtained. Mixing of 1kg packs can be done by hand but care must be taken to ensure homogenus mixing. Under no circumstances should part packs be used, or part mixing be attempted. Application Due to the easy workability of the product, a variety of instruments such as trowel, scraper, filling knife and squee - gee can be used. After mixing, material can be taken directly from the can, or subdivided onto spot boards for individual applicators. Nitomortar FC can be overcoated with all epoxy coatings after a minimum curing period of 24 hours. Prior to overcoat - ing, the surface of the fully cured Nitomortar FC should first be abraded to assist adhesion, and then cleaned to a dust-free finish.

Hardened material can only be removed mechanically. Estimating Supply Nitomortar FC : 1.0, 3.2 and 4.0 litre packs Fosroc Solvent 102 : 5 and 25 litre cans Coverage and yield: Coverage of Nitomortar FC is wholly dependant upon surface conditions, site trials are therefore recommended to ascertain actual usage on uneven substrates. As a guideline when applied at 200 microns dft coverage is approximately 5m 2 /litre. Storage Shelf life 12 months if kept in unopened tins and stored in a dry place away from direct sunlight. Storage conditions Store in dry conditions in the original, unopened containers. If stored at high temperatures the shelf life may be reduced to 4 to 6 months. Limitations - Do not mix part packs under any circumstances. - Nitomortar FC should not be exposed to moving water during application. - Exposure to heavy rainfall prior to final set may result in surface scour. - If any doubt arises concerning temperature or substrate condition, consult the local Fosroc office. Precautions Health and safety Nitomortar FC and Fosroc Solvent 102 should not come in contact with skin or eyes, or be swallowed. Ensure ade - quate ventilation and avoid inhalation of vapours. Some people are sensitive to resins, hardeners and solvents. Wear suitable protective clothing, gloves and eye/face protection. If working in confined areas, suitable respiratory protective equipment must be used. The use of barrier creams pro - vides additional skin protection. Should accidental skin contact occur, remove immediately with a resin removing cream followed by soap and water. Do not use solvent. In case of contact with eye, rinse immediately with plenty of clean water and seek medical advice. If swallowed seek medical attention immediately - do not induce vomiting. Fire Nitomortar FC is non-flammable. Fosroc Solvent 102 is flammable. Keep away from sources of ignition. No smoking. In the event of fire extinguish with CO 2 or foam. Do not use a water jet. Flash points Fosroc Solvent 102 : 33ºC For further information, refer to the product materials safety data sheet. Additional information Fosroc manufactures a wide range of products specifically designed for the repair and refurbishment of damaged reinforced concrete. These include hand-placed and spray grade repair mortars, fluid micro-concretes, chemical-resist - ant epoxy mortars and a comprehensive package of protec - tive coatings.
