A 230g container is required for a 8L Durafloor HP kit, or half the quantity for a 4L Durafloor HP kit. Epoxy screeds Durafloor HP may be applied to Parchem’s epoxy resin screeds. High spots or trowel marks should be rubbed down and dust and other debris removed by vacuum cleaning. Overcoating times may be applicable - consult Parchem for advice. Mixing Stir the base and hardener components prior to mixing. Add the 1 kg (or 2 x 500 g) Durafloor Colour Pack (1 x 500 g Durafloor Colour Pack for a 4 litre pack) to the base component and mix thoroughly using a low speed electric drill and suitable spiral mixer for 1 minute. Add hardener component and mix for a further 3 minutes. For wall applications Durafloor Thickener can be added into the mix at the same stage as the Durafloor Colour Pack component addition. To maximise pot life pour mixed components into a tray before application. Application 1st Coat Following the required preparation, apply Durafloor HP by brush or roller at a rate of 4 - 5 m²/litre. When a slip resistant finish is required, the appropriate grit should be applied as soon as sufficient area has been coated. The Durafloor Medium Grit should be lightly and uniformly broadcast over the wet Durafloor HP. The size and distribution rate of the frit should be in accordance with that prior agreed to by the client or their representative. If any areas have lost their gloss, recoat lightly before applying grit. When the first coat is hard (usually the next morning - refer re-coat times in “Properties” section) sweep or vacuum off all excess grit. For good appearance and easier cleaning, it is important that all loose grit be removed at this time. 2nd Coat Mix the components as before and using a paint roller (deflocked 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 / rollers to be washed thoroughly at least once each hour, using Solvent 10. Ensure all solvent is removed before reusing. Brushes / rollers to be discarded after use. At temperatures of 20 - 30°C foot traffic may be permitted after 24 hours, and light vehicular traffic after 72 hours; however, in cold weather a longer period before use may be required. Do not apply below 10°C. Allow 5 - 7 days before subjecting to chemical attack or abrasion. Limitations Durafloor HP should not be applied to any surface subject to back water pressure; otherwise failure of the bond is likely to occur. Intending users should always consult Parchem if there is any doubt as to whether a proposed application may involve conditions other than “ordinary”. Such extraordinary conditions include: „ Porous or poor quality concrete causing excessive use and absorbency of the product „ Unusually cold condition during curing (<10°C) „ Elevated temperatures of service (>40°C) e.g; floors subject to hot water „ Severe, or unusual, chemical attack „ Severe, or unusual, conditions of service beyond the limiting physical and chemical properties of epoxies Care should be taken in selecting colours as some will darken or develop a brown tinge when exposed to sunlight or certain chemicals. This effect is noticeable on white, light coloured and grey systems; on brown, yellow and red colours it is less noticeable. Durafloor HP is not recommended for exterior use where it is subject to sunlight or in applications involving prolonged chlorinated water immersion. Contact Parchem for detailed information. Durafloor HP should not be applied on to surfaces known to suffer from rising damp or having a relative humidity reading greater than 80%. Refer to Parchem for further advice. Durafloor HP should be applied only when the substrate temperature and the ambient temperature is above 10oC. Durafloor HP is not recommended as an application over tiles. Solvent must not be added to Durafloor HP under any circumstances unless agreed in writing by Parchem’s Technical Department for specific applications. Some solvents, including acetone and methylated spirits will significantly affect the curing and intercoat adhesion of epoxies. Cleaning All tools and equipment should be cleaned immediately after use with Solvent 10. Hardened material can only be removed mechanically. 'XUDÀRRU® HP
