Resistance to spillages (examples only) • Toluene • Sulphuric Acid 30% • Acetic Acid 5% • Skydrol • Sodium Hydroxide 30% • Sodium chloride • Ammonia 20% • Kerosene • Used sump oil • Petrol • Hydrochloric acid • Lactic acid 5% • C41 (Kodak) chemistry • Ajax Liquid Gel (clear) • Vegetable oils Surface staining may result from exposure to some aggressive chemicals. Good housekeeping is essential in areas where chemical spillage is likely to occur. It is especially important that such spillage should not be allowed to dry since very much higher concentrations of chemicals will then result. Maintenance The service life of a floor can be considerably extended by good housekeeping practices. Regular cleaning of Durafloor FC may be carried out using a rotary scrubbing machine with a water miscible cleaning agent or by hot water washing at temperatures up to 50°C. Application Instructions Surface preparation It is essential that Durafloor FC is applied to sound, clean, dry substrates in order to achieve maximum adhesion between the floor coating and substrate. Because Durafloor FC is a coating, the substrate must be fine textured. Any surface irregularities may show through causing excessive wear on high spots and changing the perceived colour of the coating. If surface preparation produces an excessively deep profile on the substrate, advice should be sought from Parchem regarding suitable methods to produce a smooth and level substrate. Steel should be sandblasted or abraded to remove all scale, rust, grease, etc. New concrete floors Unless water-reduced, floor should be at least 28 days old and give a hygrometer reading not exceeding 80% RH. Dry removal of laitance is required via light grit-blasting or grinding. Dust and other debris should then be removed by vacuum brush. Old concrete floors A sound, clean substrate is essential to achieve maximum adhesion. Light grit blasting or grinding should be carried out as for new concrete floors. Oil and grease penetration should be removed by hot compressed air treatment and primed with Nitomortar 903. Adhesion tests must be carried out to confirm sufficient preparation. Epoxy screeds Durafloor FC may be applied to Parchem epoxy resin screeds. High spots or trowel marks should be ground / sanded down and dust and other debris removed by vacuum cleaning. Unless the epoxy screed is less than 3 days old, the entire surface should be sanded and solvent wiped before applying the Durafloor FC. Mixing Stir the base and hardener components prior to mixing. Into the base container add one 500g Durafloor Color Pack and mix the material for 1 minute using a slow speed drill fitted with a mixing paddle. Add the hardener component and continue to mix for a further 3 minutes. Apply mixed product to floor immediately. Application First coat Apply Durafloor FC by brush or roller at a rate of 4 - 6 m²/litre or slightly heavier if medium grit is to be used. As soon as approximately 1m² has been coated, cover with the required grade of grit. Durafloor Medium Grit should be lightly and uniformly broadcast over the wet Durafloor FC surface. If any areas have lost their gloss, recoat lightly before applying grit. When the first coat is hard (3 hours after application, but not later than 24 hours after application), sweep off all excess grit. For good appearance and easier cleaning, it is important that all loose grit be removed at this time. Second coat Mix the liquids as before and using a paint roller (mohair is recommended) apply a coat over the grit. (See ‘Coverage’). It is important that this final coat be uniform but the exact rate of application may be varied to suit the finish required. A heavy final coat will give an easily cleanable floor but a fairly light coat will give the best slip resistance in wet conditions. Brushes and rollers must be washed thoroughly using Solvent 10, at least once each hour and immediately after finishing. Rollers should be discarded after use. At temperatures of 20°C - 30°C ordinary light traffic may be permitted after 12 hours; however, in cold weather a longer period before use may be required. For best results, do not apply below 7°C. Allow 4 days (at 20°C) before subjecting to chemical attack or severe abrasion. Durafloor FC should not be applied to any surface subject to back water pressure or rising damp; otherwise failure of the Durafloor® FC
