Mapei Kerapoxy Adhesive - Two Component Epoxy Adhesive - White (10kg)

Product Code: 31457

Two-component, epoxy adhesive with no vertical slip for ceramic tiles and stone material\nCLASSIFICATION ACCORDING TO EN 12004 Kerapoxy Adhesive is an R2T class reactive (R), improved (2) adhesive with no vertical slip (T).\nWHERE TO USE\nInternal and external bonding of ceramic, porcelain and stone to floors and walls, on all substrates normally used in the building industry.\nSome application examples\n\nBonding of all types and forms of ceramic tiles.\nRigid bonding of bullnose and special ceramic tile shapes.\nBonding tiles in fibreglass swimming pools.\nBonding marble doorsteps and windowsills.\n\nTECHNICAL CHARACTERISTICS\nKerapoxy Adhesive is a two-component, epoxy resin-based high strength mortar with silica sand and special additives, according to a formula developed in MAPEI’s own research laboratories. When the two components are mixed together, a thixotropic mix is obtained which can be easily applied, even on vertical surfaces, at a thickness of up to 1 cm in one single coat.\nKerapoxy Adhesive has the following characteristics:\n\nExcellent durability and resistance to ageing\nPerfect bonding on all types of substrate commonly used in the building industry\nHardens by chemical reaction without shrinking, becoming extremely strong.\n\nRECOMMENDATIONS\n\nDo not add water or solvents to Kerapoxy Adhesive to increase workability.\nUse the product at temperatures between +10?C and +30?C.\nThe packages are pre-dosed and, therefore, it is not possible to make mixing ratio errors. Do not rough guess the quantities when mixing the two components: hardening will be compromised if the catalysing ratio is wrong.\nIf residues of the product remain attached to the tiles, use water for cleaning while the residue is still fresh. Use Pulicol if the product is hard, or remove mechanically.\nKerapoxy Adhesive must not be used for sealing flexible joints or those which are subject to movement (use Mapesil AC or Mapeflex PU21).\nKerapoxy Adhesive must not be used on wet surfaces.\nKerapoxy Adhesive must not be used on dirty or crumbly surfaces.\n\nAPPLICATION PROCEDURE\nPreparation of the substrate The substrate must be well cured, mechanically strong, dry and free from flaking parts, grease, oil, paint, wax etc. Cementitious substrates must not shrink after laying the tiles. Therefore, during good weather, the curing time must be at least one week per centimetre of thickness, unless screeds are made using a special MAPEI binder such as Mapecem, Topcem or with Mapecem Pronto or Topcem Pronto. If these guidelines are not followed, the bond of Kerapoxy Adhesive to the substrate could be compromised.\nOn ferrous surfaces, rust must be removed by sand-blasting.\nOn gypsum, plaster-board and anhydrite surfaces, we recommend consolidating the surface by applying a coat of Primer EP or Mapeprim SP.? Anhydrite surfaces must be additionally mechanically abraded prior to priming.\nPreparation of the mix\nThe two components which make up Kerapoxy Adhesive are supplied in pre-dosed tubs.\n\npart A: grey/white colour, 80 parts by weight; \npart B: beige colour, 20 parts by weight.\n\nThe ratio between the two components is compulsory, and any modification may cause the product to harden incorrectly. Pour the catalyst (part B) into the container with part A and mix well until a smooth paste is obtained. We recommend using a lowspeed electric mixer to guarantee perfect bonding, and to avoid overheating of the mix which would reduce working times. Stir from the bottom and the sides to ensure a uniform dispersion of all components. Use the mix within 45 minutes of its preparation.\nApplication\nSpread the adhesive onto the substrate using a suitable notched trowel. If the adhesive is used for bonding special tile shapes such as torelli, also fill the gaps on the back of the piece with the Kerapoxy Adhesive mix before laying. Press the pieces to be bonded by pressing them together to guarantee good buttering. Once set, the bond will be very tough.\nThe surrounding temperature effects the hardening time of the product. At +23?C it remains workable for approximately 45 minutes, and this time reduces as the temperature increases.\nSET TO LIGHT FOOT TRAFFIC\nFloors may be stepped on after 10-12 hours at +23?C.\nREADY FOR USE\nThe surfaces may be put into service after 2 days.\nCleaning\nTools and containers may be cleaned while the product is still fresh using plenty of water. Once Kerapoxy Adhesive has set, they may only be cleaned mechanically or with Pulicol.\nCONSUMPTION\nConsumption is 1.5 kg/m2 per millimetre of thickness.\nPACKAGING\n10 kg kits: component A: 8 kg tubs; component B: 2 kg cans.
