The following steps are involved in the application. „ Thoroughly prepare the floor surface. Correct surface Page 2 251 preparation helps to achieve the necessary adhesive bond between the substrate and the new floor. Mechanically scarifying or captive blasting is the normal suggested method „ All existing expansion or movement joints should be followed through the new floor surface Repair Faults / defects in the base concrete floor will reflect through the Durafloor SLX so it is important to “make good” the concrete before application of the Durafloor SLX. These repair are generally carried out using Nitomortar 903 and fillers or a suitable epoxy fairing mortar Priming „ Apply 1 - 2 coats of Nitomortar 903 and allow to cure. Touch dry between prime coats and 12 - 24 hours prior to the application of Durafloor SLX „ Efficient sealing of the concrete surface is essential to minimise surface defects in the final finish Mixing 1. Scrape entire contents of the 1.0 kg colour pack (or 2 x 500 g colour packs) into the base component (only use Durafloor Colour Packs). 2. Add the entire contents of the hardener to the base and colour pack mixture and mix for 1 minute using a slow speed mixer fitted with a large spiral type mixing attachment. 3. After 1 minute mixing, slowly add one bag of the Durafloor SL fillers. 4. Continue mixing entire mix for a minimum of 3 minutes at 350 - 500 rpm once all components have been added. Note: Mix in an efficient manner to ensure no colour pigment streaking is visible and scrape the side walls of the mixing vessel with a long bladed spatula to dislodge any unmixed material. Placing „ Apply the Durafloor SLX topping. The material is poured on to the primed surface and spread with a steel trowel to achieve a 2 - 4 mm seamless topping „ Using a spiked roller, remove air entrainment and allow to cure „ Install the most appropriate Parchem joint sealant. This will depend on the anticipated movement accommodation factor and the end use of the new floor. For further advice, consult your local Parchem sales office Installation times will vary according to site conditions and the size of the area involved. If a slip-resistant finish is required this can be achieved by application of Durafloor HP incorporating suitable anti-slip aggregates. Refer to the Durafloor HP Technical Data Sheet. Cleaning Durafloor SLX and associated primer should be removed from tools and equipment with Solvent 10 immediately after use. Hardened material can only be removed mechanically. Limitations Durafloor SLX should not be applied on to surfaces known to or likely to suffer from rising damp conditions or have a relative humidity greater than 75%. Suspect concrete floor should be checked using a Hygometer to check the moisture level before proceeding. Durafloor SLX is not a ‘floor levelling’ product and will follow the contours of the sub-floor. If the floor requires levelling, consult your local Parchem sales office for further advice. In certain conditions a light oily film may appear on the surface of the floor during curing. Where overcoating is to occur, remove this film by solvent wiping or cleaning with a recognised reactivating solution. This film can also be removed once the Durafloor SLX is fully cure by cleaning the surface with a mild detergent in water. Durafloor SLX does not produce a ‘mirror finish’. Some imperfections in the finish are always present. Durafloor SLX is not resistant to scratching and marking from mechanical damage and abrasion. Durafloor SLX is designed as a rapid installation, seamless floor. Some floor areas, especially the darker coloured Durafloor SLX, may show slight ‘dimpling’. This is common and should be expected. It has no effect on the end flooring project being seamless and hygienic. In areas where significant thermal shock is likely to occur, consult your local Parchem sales office. Durafloor SLX should not be applied to asphalt, weak or friable concrete, unmodified sand cement screeds, PVC tiles or sheet or substrates known to move substantially e.g. steel walkways. For information on other substrates, consult your local Parchem sales office. Durafloor SLX should be applied only when the substrate temperature and the ambient temperature is above 10oC. Durafloor SLX is not UV stable - discolouration may occur even in internal environments including exposure through windows. Durafloor® SLX
