Nitoflor Lithurinconstructive solutions11CI/SfB: Yu5May 2009Permanent hardening and dustproofingcompound for concrete surfacesUsesAs a surface hardener for new and old concrete floor toprevent dusting and to increase durability. Suitable for useon concrete and granolithic surfaces. Typical applicationsinclude industrial floors, light engineering works,warehouses, animal feed and milk parlours, abattoirs, carparks, dams, reservoirs, tanks, silos and flues.AdvantagesHighly durable, improves abrasion resistance andreduces chemical attack from oils and greasesEasy to apply, no special equipment or skills requiredEliminates dust formation from within the treatedsurfaceEconomical and low cost method of floor protectionDescriptionNitoflor Lithurin is a white, soluble, crystalline powderbased on metallic fluorosilicates and wetting agents.When Nitoflor Lithurin is mixed with water and applied tothe floor, the solution penetrates the concrete reactingwith lime and other soluble particles to form granite hardcrystals, leaving a permanent, hard wearing and dust freesurface.PropertiesPenetration: Specially selected wetting agents inNitoflor Lithurin improve the depth ofpenetration resulting in a more durablefinish better than that of other surfacetreatments which merely form a superficialskinHardness:Anti-dust:Chemicalresistance:The surface hardness is achievedthrough a chemical reaction within thecementitious material. This givesin-depth protection against heavy traffic andother forms of abrasionThe chemical elimination of free limeand other soluble particles creates a tightlybound surface resistant to dustingThe inert crystalline compoundsformed by Nitoflor Lithurin applicationreduce the absorbency of the surface andimprove resistance to solvents, greasesand commonly used chemicalsConsult the Fosroc Customer Service Department fordetails on resistance to specific chemicalsApplication instructionsPreparationSurfaces to be treated with Nitoflor Lithurin must bestructurally sound and free from loose materials. Cracksand holes should be repaired with Nitomortar PE resinmortar (see separate data sheet).Oil and grease contamination should be treated with asuitable chemical de-greaser and washed with cleanwater and allowed to dry. Any laitance or existing coatingmust be removed prior to application as these will preventpenetration.New concrete floors must be allowed to cure for 14 daysprior to treatment. Coloured floors should be allowed tocure for 28 days prior to treatment and a small area testedwith Nitoflor Lithurin to assess the effect on the colour.Nitoflor Lithurin must only be applied to dry surfaces tomaximise penetration.MixingDissolve 15 kg of Nitoflor Lithurin with 45 litres (10gallons) of water in plastic containers and stir untilcompletely dissolved. Metal containers may be usedprovided the solution is used within 24 hours.ApplicationEnsure that the surface to be treated is dry and apply themixed Nitoflor Lithurin at a rate of approximately 1 litre toevery 4.5 m² using a soft broom or brush. Ensure that thesurface is thoroughly saturated with the solution and wellbrushed out to prevent ponding.Allow the solution to be absorbed into the floor for a periodof up to 2 hours. Do not allow the floor to dry out and whilstthe floor is still damp wash the surface thoroughly withclean water. Remove all surplus solution and water asstated in disposal instructions.Failure to do so will result in a white dusty deposit left ondrying.Nitoflor Lithurin should not be discharged into drains andstorm tanks. (See disposal instructions.)Two coat application is recommended for completetreatment, but very dense, well trowelled surfaces such asgranolithic toppings, power floated or vacuum dewateredconcrete will generally require only a single coat.If required, re-apply the solution after 24 hours ensuringthat the floor is dry. All surplus solution must be removed.EstimatingNitoflor Lithurin is supplied in 15 kg buckets. One coatapplications require approximately one bucket to coverapproximately 200 m² . Two coat applications requireapproximately one bucket per 150 m². The degree ofporosity will affect the coverage rate achieved.Page 1

11CI/SfB: Yu5May 2009Nitoflor LithurinLimitationsNitoflor Lithurin solution is toxic and cannot be dischargedinto drains and storm tanks. Nitoflor Lithurin must bedisposed of in accordance with the EnvironmentalProtection Act 1990.Metal, glass or paintwork must be protected againstNitoflor Lithurin. Should any splashes occur these mustbe removed immediately and disposed of by following thedisposal instructions.2 kg of lime for neutralisation. The pH of the solution mustalways be checked to ensure that complete neutralisationhas occurred.The reaction with the lime produces a white precipitate ofcalcium fluorosilicate which may be disposed of on alandfill site. The remaining liquid can be washed awaydown drains with excess water.All health and safety procedures and precautions must beadhered to whilst handling and disposing of the solution.StorageNitoflor Lithurin has a shelf life of 12 months if stored incool dry conditions in original, unopened buckets.PrecautionsHealth and safetyFor further information see appropriate Product SafetyData Sheet.FireNitoflor Lithurin is non-flammable.DisposalDue to the Environmental Protection Act 1990 solublefluorosilicates i.e. Nitoflor Lithurin cannot be dischargedinto drains or storm tanks and the given guidelinesshould be followed.After treatment, the surplus solution and subsequentwashings must be vacuumed up to remove all traces ofthe solution from the surface. The storage andtransportation of this solution must be in polythene,plastic or stainless steel containers that can be lidded fortransport.The residual liquid should be treated with builders limei.e. calcium hydroxide, in order to neutralise the solution.The lime should be thoroughly mixed with the solution, leftto stand for 24 hours and pH checked with litmus paperuntil a pH7 or above is achieved. Both lime and litmuspaper can be obtained from any chemical laboratoryequipment supplier such as BDH of Poole, Dorset.Builders lime can be obtained from any good buildersmerchant. As a guideline, 10 litres of solution will requireImportant noteNitoflor is the trademark of Fosroc International LimitedFosroc products are guaranteed against defective materials and manufacture and are sold subject to its standard Conditions for theSupply of Goods and Services, copies of which may be obtained on request.
