Bostik Patchfix Coarse & Fine Fillersmay be added to produce a trowellable high build mortaror a pourable flowable grout.AppearanceViscosityFlammabilityPart A: Amber/Beige thixotropicliquid; Part B: Black thixotropicliquidFlowable, pourableNon flammableUSES• Suitable for use on damp substrate.• Grouting heavy duty supports beneath crane andtransporter rails.• Anchoring bolts, bars and fixings.• Bonding new to old concrete.• Adhesive promoter.• Filling in holes, cavities.• Repairing cracks in horizontal surfaces.• Grouting off column bases.• As a high strength repair mortar when mixed withPatchfix Filler.• As a protective coating for concrete and steelstructures.• Reinforcement bar primer.• Corrosion protection on steel reinforcement prior toapplication of concrete repair mortar.FEATURES• High flow properties• Bonds to damp substrates• Rapid hardening and strength gain• High chemical resistance• Pre-measured kits make ease of use• High tensile and compressive strength• 100% solids epoxy• Excellent adhesion to most substrates• Cures at temperatures down to 5 o C• Negligible shrinkage• High mechanicalSolid content by weight 100%Chemical resistance Very goodTensile strength30MPa approx.Compressive strength 110MPa approx.Flexural strength25MPa approx.Tensile bond strength 10MPa approx.Modulus of elasticity 4.5 x 10 3 MPaService temperature -10 o C to +65 o CHead distortion temperature 80 o C approx.Hardness>80 shore DPot life45 – 50 mins@25 o CTack free time1.5 – 2.5 hours @25 o CMixing ratio100:20 (part A:B) by volumeMin. application temperature 5oCMax. application temperature 35oCDensity1.60 kg/LWater absorption

APPLICATION INSTRUCTIONSSURFACE PREPARATIONClean the surface and remove any dust, unsoundmaterial, plaster, oil, paint, grease, corrosion deposits oralgae. Roughen the surface and remove any laitance andexpose aggregate by light scabbling or grit-blasting. Oiland grease deposits should be removed by steamcleaning, detergent scrubbing or the use of proprietarydegreaser. All residual ponding water must be removed,the substrate may be moist but not wet. All anchor boltholes must be free of water and debris prior to placing ofTechflow Epoxy Grout. Steel surfaces such asreinforcement bars should be grit-blasted or scabbled toremove any corrosion.MIXINGThe mix ratio is 5:1 by volume, 5 parts Part A and 1 partPart B.Any steel reinforcement and formwork should beprepared, cut to size and shape and made ready forassembly before mixing commences. Care should betaken to ensure that Techflow Epoxy Grout is thoroughlymixed. The hardener and base components should bestirred separately before mixing to disperse anysettlement. The entire contents of the hardener (Part B)tin should then be poured into the base (Part A) tin andthe two materials thoroughly mixed using a suitableslow-speed drill and high shear mixing paddle. Mix for 2minutes until a fully uniform colour is obtained, the sidesof the tins should be scraped, mixing should continue fora further 2 minutes.To facilitate mixing and application at temperatures below10 o C, the separate components should be warmed in hotwater up to a maximum temperature of 25 o C beforebeginning to mix. If heated to 25 o C, the subsequentlymixed material will need to be used more speedily as thepot-life will be reduced to 30 - 40 minutes. Alternatively,the material should be stored in an environmentcontrolled to 20 o C and only removed immediately beforeuse.PLACINGTechflow Epoxy Grout should be applied as soon as themixing process has been completed. It should bebrushed, rolled or spray applied to the prepared surfaces.The new concrete or screed should be applied to thecoated substrate within 90 minutes at 20 o C.Where Techflow Epoxy Grout is to be used as part of arepair system to form a substrate/repair barrier, careshould be taken to achieve an unbroken coating. Onecoat should be applied and allowed to gel (cure).A second coat should be applied and used as thebonding coat. In some situations (e.g. sprayed concreterepairs) it may be advantageous to scatter dust-freesharp sand over this coat and the concrete repair mortarshould be applied prior to the Techflow Epoxy Grout fullycuring (within 90 minutes of Epoxy Grout application).As soon as the Techflow Epoxy Grout has been applied,any required steel reinforcement and/or formwork shouldbe erected and fixed securely in place. Ensure theTechflow Epoxy Grout is tacky prior to application ofrepair mortar. If the application of Epoxy Grout has curedand is touch dry, DO NOT apply cementitious repairmortar. Re-apply with a second coat of Techflow EpoxyGrout to be the first coat and allow to reach a tackyconsistency before applying the cementitious repairmortar.Where Techflow Epoxy Grout is to be used for groutingbolts or starter bars on horizontal surfaces then holediameter must be approximately 1.5 times the diameter ofthe actual bolt to be grouted. Set the bolt in the clean,contamination free hole and pour the mixed TechflowEpoxy Grout from one side only, ensure that this isconducted in a continuous operation so as to avoid airentrapment and to ensure complete coverage around thebolt or starter bar. Techflow Epoxy Grout may also beused as an Epoxy Binder to obtain a specific consistencywhen mixed with Bostik Patchfix Coarse/Fine Fillers(Refer to Technical Data Sheets on Patchfix Fillers).CLEAN-UPClean up uncured material and equipment immediatelyafter use using Bostik Solvent 9907. Do not use solventson skin. Cured Epoxy Grout is difficult to remove viachemical means and mechanical means may benecessary.PACKAGINGTechflow Epoxy Grout is available in 4 litre and 16 litrekits.COVERAGEOne litre will cover 1m 2 at 1mm thick. As an epoxybonding agent for new to old concrete the coverage rateis 4-5m 2 /litre.STORAGETechflow Epoxy Grout has a shelf life of 12 months fromdate of manufacture when kept between 10 o C and 30ºCin a dry store in the original, unopened bags.All material shall be stored under cover in a manner thatwill prevent damage preferable on pallets and protectedfrom excessive heat and moisture. Do not freeze.PRECAUTION• Techflow Epoxy Grout when mixed in large volumes,greater than 10 litres is highly likely to cure fasterreducing the pot life of the mixed material in the tin.TECHFLOW EPOXY GROUT PAGE 2 of 3.

• Low temperature working: the minimum applicationtemperature is 5 o C. In temperatures below 10 o C,the separate components should be heated in warmwater (up to 25 o C) or stored in a temperaturecontrolled environment for 12 hours before use.These measures will facilitate mixing andapplication. Normal precautions for winter workingwith cementitious materials should then be adopted.• High temperature working: At ambient temperaturesabove 30 o C, the material should be stored in theshade or in an air-conditioned environment for 12hours before use.• Do not dilute Epoxy Grout with solvents as this willseverely affect the ultimate performance of theproduct.• Only mix as much Techflow Epoxy Grout that can beused within the pot lifeHEALTH AND SAFETYSome people are sensitive to epoxy resin. Gloves andprotective goggles must be worn during application anduse.• Avoid contact with the skin, eyes and avoidbreathing its vapour.• Wear protective gloves when mixing or using.• If poisoning occurs, contact a doctor.• If swallowed, Do Not induce vomiting. Give a glassof water.• If skin contact occurs, remove contaminatedclothing and wash skin thoroughly for a minimum of15 minutes.• If in eyes, hold eyes open, flood with water for atleast 15 minutes and see a doctor.• For more detailed information refer to the MaterialSafety Data Sheet.FIRETechflow Epoxy Grout is non-flammableDisclaimer: The information detailed in this data sheet is liable tomodification from time to time in the light of experience and normalproduct application, and therefore customers are advised to check withBostik Holding Hong Kong Limited, quoting the reference number thatthey possess the latest issue.
