Fosroc Nitocote EP403 when cured provides a corrosion, chemical and abrasion resistant film that is suitable for application to sewage works, marine environments, basements and tunnels. It is particularly useful where concrete surfaces are damp and cannot be dried out.
The material cures to provide a smooth, tough and resistant finish. Available in light grey.
All surfaces must be smooth, sound and free from debris, loose or flaking material and areas of standing water. Surfaces must be free from contamination such as oil, grease, dust, loose particles and organic growth. Concrete surfaces must be fully cured, laitance free and free from any traces of shuttering release oils and curing compounds. Spalled surfaces, those containing large blow holes or surface imperfections should be repaired or rendered using a Fosroc approved repair mortar or render.
All surfaces should then be grit blasted to remove all foreign matter and open up all blow-holes, and provide a suitable key for Nitocote EP403. All blow-holes and imperfections should be filled with Fosroc Nitomortar FC. Consult the data sheet for pot life and overcoating time.
All surfaces should be grit blasted to meet the requirements of BS 7079 Sa2.5. The lining work should be programmed so that newly cleaned steel is coated as soon as possible before the formation of rust or scale.
The minimum application temperature is 5°C.
All surfaces should be treated with two coats of Nitocote EP403. The thoroughly mixed material should be applied with a suitable brush. The first coat must be firmly applied and be well scrubbed into the surface, ensuring a uniform coating with a wet film thickness not less than 200 microns. The first coat should be allowed to dry for not less than 6 hours and not more than 18 hours at 20°C.
The second coat should be applied exactly as above, again achieving a wet film thickness not less than 200 microns. For cold weather working, it is recommended that Nitocote EP403 be stored in a heated building and removed immediately before use, as workability deteriorates and curing times increase at lower temperatures.
