Typical uses for the system are in wet processing zones in chemical processing plants and food preparation and manufacturing areas. Advantages „ Handles extreme temperatures „ High chemical resistance „ Hard wearing – abrasion resistant „ Non tainting during application „ Low odour during application „ Slip resistant „ Fast turnaround times „ Easy to clean „ Anti-microbial properties Description Durafloor X produces a topping and coating system with a textured finish, which provides a hard-wearing, chemically resistant floor that can handle extreme temperatures. The system also has anti-microbial properties which reduce the growth of bacteria and mould. Design Criteria The Durafloor X system consists of a topping, a slip-resistant aggregate and a top coat. The topping is designed to be applied at three different thicknesses. The depth of the topping is determined by physical site parameters and the degree of temperature resistance required by the floor (see properties table for temperature resistance). Properties The following results were obtained in controlled laboratory conditions at 20oC and 50% relative humidity. %RQG6WUHQJWK Greater than cohesive strength of 25MPa concrete. >1.5 MPa &RPSUHVVLYH6WUHQJWK > 50 MPa 7HPSHUDWXUH5HVLVWDQFH 3 - 4 mm system = -5°C to 65°C 5 - 6 mm system = -5°C to 90°C 8 - 9 mm system = -25°C to 120°C &KHPLFDO5HVLVWDQFH Good resistance to sugars and most organic and inorganic acids. Please check resistance to required chemicals including dilution percentage and temperature with your local Parchem sales office 6OLS5HVLVWDQFH7HVW AS/NZS 4586:2004 Appendix A (wet pendulum test) System: 5 - 6mm Mean BPN: 64 Class: V 1RWH The Slip rest results shown are available on request. Reasonable variations are to be expected on site due to site-specific conditions and variances with 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.

Preparation Durafloor X should be applied within the temperature range of 5-30°C. Refer to Parchem for advice on application outside of this temperature range. Concrete substrate should be a minimum strength of 25MPa, free from coatings and other contaminants. The substrate should be dry to less than 90% relative humidity, have an effective damp-proof membrane installed and be free from rising damp and ground water pressure. Concrete should ideally be 28 days old, however Durafloor X may be applied to concrete as early as 7 days old providing high strength concrete is being used and the curing / drying conditions are suitable. Please contact Parchem for advice under these conditions. All cementitious laitance to be removed to expose sound concrete beneath and provide a clean, dry, dust free, open-textured surface via totally enclosed shot blasting and/ or scarification. Floor areas beneath air-conditioning units, ducting etc. and around perimeter should be prepared using hand held preparation equipment. Any damaged areas must be made good with a suitable repair mortar. Contact Parchem for advice. Any rough or uneven areas to be smoothed with an epoxy scratch coat, of Durafloor X Primer with F4 fillers. May 2014
