Ambient temperature at the time of application 20°C 30°C 40°C. Max elapsed time for light spiked rolling from time of final trowel 30 – 60 mins 20 – 30 mins 10 – 20 mins Ø Surface Preparation: • New concrete, or cementitious substrates, should be at least 28 days old and have a moisture content not exceeding 5% (Rh <75%).• The substrate should be clean, sound and free from contamination such as mortar and paint splashes curing compounds, oil and grease. Excess laitance deposits are best removed by light mechanical scabbling, grinding or grit/captive blasting followed by vacuum cleaning to remove dust debris. All preparation equipment should be of a type approved by Fosroc.• All blowholes and other surface undulations greater than 1 mm in depth should be repaired with a proprietary, repair compound - consult the local Fosroc office for specific recommendations.• Oil and grease contamination must be completely removed by grinding down to sound, clean concrete. Alternatively, captive/grit-blasting techniques can be used to provide the required substrate.• Where these methods are considered impracticable, alternative methods may be considered but a clean, sound and dry substrate must still result. In particular it is essential that the substrate does not suffer from conditions of rising damp. Fosroc must approve any alternative preparations prior to commencement of work, as Fosroc will not accept responsibility under any other condition. • Isolation Joint treatment:- Nitoseal PU50 single-component, non sag, medium modulus, moisture cure, polyurethane hybrid joint sealant having properties shore A hardness-32, Average peel strength-220N,Elastic cover of 80% as per guidelines of EN ISO 7389, MAF up to 50%.

Priming: Apply epoxy resin primer Nitoprime 25 after mixing the base and hardener mechanical using a slow speed heavy duty drilling machine (300-400 rpm) fitted with a suitable paddle to achieve homogeneous mix and apply to prepared surface at a coverage rate of 5.5 to 6.5 sqm/lit. Ø Application of Nitoflor EU5 (2mm): • Nitoflor SL1000 flooring is supplied in four pre-weighed packs (base, hardener, aggregate & colour pack) which are ready for immediate on-site use. Part mixing of these components is not acceptable and will affect both performance and appearance of the finished floor and would furthermore automatically invalidate Fosroc’s standard product guarantee.• Mixing should be carried out using either a forced action mixer; or a heavy duty, slow-speed drill with proprietary mixing paddle attachment. Fosroc should of a type and capacity approve all such equipment. The components should be mixed in a suitably sized mixing vessel.• Add the entire contents of the colour pack into the base pack and mix for 15-30 seconds, until homogeneous.• Empty the hardener pack into the mix of base and colour pack and mix until an even texture and colour is obtained.• Thereafter, the contents of the graded aggregate pack should be slowly added and mixing carried out for a further 3 minutes until completely homogenous material is obtained.• Application of Nitoflor EU5 (laying):• The applicator should ensure that there are sufficient supplies of plant, labour and materials to make the mixing and subsequent application process a continuous one for any given, independent floor area.• Once mixed, the material must be used within its specified pot life - see ‘Properties’ section of the relevant data sheet.• The material should be spread to a uniform thickness across the floor area using a squeegee or a notched trowel.• Overcoating:• Nitoflor EU5 will be ready for overcoating, using Nitoflor SL 1000, after 48 hours from completion of application.  Application of Nitoflor SL 1000 (1mm):- • Mixing Nitoflor SL 1000:- • Nitoflor SL1000 flooring is supplied in four pre-weighed packs (base, hardener, aggregate & colour pack) which are ready for immediate on-site use.

It should be spread to the required thickness using a serrated trowel; with care taken not to overwork the resin, spreading evenly and slowly. • Immediately after laying, the material should be rolled, using a spiked nylon roller, to remove slight trowel marks, and to assist air release. The rolling should be carried out using a ‘back and forth’ technique along the same path. An overlap of 50% with adjacent paths is recommended. • Further light rolling may be required to remove surface imperfections, or for subsequent release of trapped air, but should be carried out in accordance with the maximum times given below: Note: Any chemical/ product specified above of equivalent quality can be used.
