CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING ROOFING WATERSTOPS WATERPROOFING JOINT FILLERS TIMBER FLOORING ALPHABETICAL All joints in the substrate must be expressed through Durafloor X. Anchorage groove details Anchorage grooves must be formed in the concrete substrate along all free-edges, bay joints, drains, at doorways, around columns and machine plinths, etc and at regular centres across the floor. These anchorage grooves are formed using a diamond cutting wheel and must be 6mm wide with a minimum depth equal to the topping thickness (3-7mm). It is essential anchorage grooves are correctly placed to aid in the distribution of mechanical stress from temperature changes and shrinkage. For further advice on this issue please consult your local Parchem sales office. Priming A primer is generally not required but may be required on very porous substrates, please contact your local Parchem sales office for advice. If required, Durafloor X Primer is the recommended primer. The primer must be allowed to become tack free before applying the Durafloor X system. Topping - mixing Pack components are pre-weighed for optimum performance. Never split or proportion packs. Stir Durafloor XT Base to redisperse any settlement. Pour the Base component into a suitable mixing container. Add the Hardener component and mix with a slow speed drill and large spiral mixer for 2 minutes, taking care not to entrain air. In temperatures less than 10°C, fillers should be preconditioned INDEX 270 to approximately 20°C to 25°C for 24 hours prior to application. Add either Durafloor XT Filler 1 or Filler 2 depending on system required. Mix until uniform. Take care not to entrain air. Then mix with 180g of Parchem Covertex Dispersant colour until uniformly tinted. Topping - application Please note this material has a pot life of approximately 15 minutes at 25°C. Immediately after mixing, spread the Durafloor XT using a steel trowel or gauging rake onto the primed floor, to the required thickness. Immediately, roll with a spiked roller to release any entrapped air. Do not roll the surface after 8 minutes after application, dependent on temperature. Late spike rolling will cause surface texture. Immediately after applying and spike rolling the Durafloor XT, broadcast to full cover the slip resistant aggregate ensuring an even finish is achieved. Allow to cure. Typically a minimum of 5 hours @ 25°C. Top coat - preparation Fully remove any loose aggregate by vacuum and sweeping prior to application of top coat. Top coat - mixing Pack components are pre-weighed for optimum performance. Never split or proportion packs. Stir Durafloor X Coat Part A to redisperse any settlement. Pour into a suitable large container and add the Durafloor X Coat Part C while mixing with a suitable mixer. Add 180g of Parchem Covertex Dispersant colour and continue to mix until a uniform colour is achieved. Add Durafloor X Coat Part B and mix for a further 2 minutes. Top coat - application Please note this material has a pot life of approximately 10 minutes at 25°C. Apply the Durafloor X Coat by squeegee and roller to fully seal the surface. Ensure the coating is applied evenly taking care that the slip resistant aggregate is fully exposed, avoid overfilling the aggregate. Please consult your local Parchem sales office regarding application of Durafloor X Coat under areas of coving. Durafloor X Coat has a short pot life - do not apply the product out of a roller tray. Coving Coving can be formed with a mortar produced from Durafloor X Primer and fillers. Vertical surfaces must be primed with unfilled Durafloor X Primer. Whilst the primer is wet or tacky, form the required cove using Durafloor X Primer with the required amount of fillers. Allow to cure. Lightly sand the surface to remove any roughness and apply a coat of Durafloor X Coat by brush/roller. Allow to cure. Trafficking Allow to cure for 24 hours at a minimum of 20°C before light trafficking. Cleaning All tools and equipment should be cleaned immediately after use with Solvent 10. Hardened material can only be removed mechanically. 'XUDÀRRU® X
