To extend pot life pour product into flat trays such as roller trays. Slip resistance test results System Used Result for Test: Appendix A Wet Pendulum (Four S Slider) AS/NZS 4586:2004 Result for Test: Appendix D Oil - Wet Ramp AS/ NZS 4586:2004 Durafloor HP with Durafloor Anti-slip Grains at 20g/m² W R10 Durafloor HP saturated with Durafloor Grit Fine W R10 Durafloor HP saturated with Durafloor Grit Medium V R13 The slip test results shown are available on request. The results were achieved in controlled laboratory conditions; reasonable variations are to be expected on site, due to site-specific conditions and variances in application. Application of the proposed system on a small test area on site, prior to commencement of works is highly recommended, to confirm actual slip resistance. Chemical properties Resistant to a wide range of chemicals. 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 practice requires spills to be quickly removed and washed. Maintenance The service life of a floor can be considerably extended by good housekeeping practices. Regular cleaning of Durafloor HP may be carried out using a rotary scrubbing machine with a water miscible cleaning agent. Refer to Parchem’s ‘Guide to Industrial Floor Maintenance”. Application Instructions Surface preparation It is essential that Durafloor HP is applied to sound, clean, dry substrates in order to achieve maximum adhesion between the floor coating and substrate. Because Durafloor HP is a relatively thin coating, the substrate must be fine textured. Any surface irregularities may show through causing excessive wear on high spots. 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. A ‘scratch coat’ of Nitomortar 903 and fillers is often used to smooth out irregularities. Steel should be grit-blasted or abraded to remove all scale, rust, grease, etc. Priming On very porous concrete an additional (3rd) coat of Durafloor HP may be required or the area may need to be primed with Nitomortar 903. New concrete floors Unless water-reduced, the 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. Depending on extent of the contamination, oil and grease penetration may be removed by hot compressed air treatment and primed with Nitomortar 903. Adhesion tests must be carried out to confirm sufficient preparation. Durafloor® HP
