Nitoflor Hardtop & Nitoflor Hardtop Standard …

1 Nitoflor Hardtop and Nitoflor Hardtop Standardconstructive solutionsNon metallic, monolithic surface hardening compoundUsesNitoflor Hardtop / Nitoflor Hardtop Standard provide a highlyabrasion resistant surface to concrete floors by the dry shake-on method which ensures that the hardwearing surfacebonds monolithically to the base concrete. They are ideallysuited for all industrial areas subject to the heaviest traffic, loading bays, trucking lanes, car parks, workshops,machine shops, ramps and Non metallic - does not rust or stain. Provides a hard, abrasion resistant surface Forms monolithic bond with base concrete Easy and economical to applyDescriptionNitoflor Hardtop / Nitoflor Hardtop Standard are qualitycontrolled, factory blended powder which are ready to use onsite.

2 They contain special hardwearing aggregates whichhave been selected for abrasion and wear resistant propertiesas well as shape and size. These latter considerations,together with the use of high performance workabilityadmixtures, produces a material which is easy to trowel intothe surface of fresh, wet concrete. Nitoflor Hardtop / NitoflorHardtop Standard cure monolithically to provide a dense,non-porous surface which is extremely hardwearing andabrasion resistant. Monolithic cure ensures that problemsnormally associated with thin 'granolithic' screeds, viz.,shrinkage, cracking, etc., are completely non-metallic, Nitoflor Hardtop / Nitoflor HardtopStandard provide a non-slip surface which will never rust supportFosroc offers a technical service to specifiers, end users andcontractors, as well as on-site technical assistance inlocations all over the resistance ( IS : 1237 - 1980) Nitoflor Hardtop / Nitoflor Hardtop Standard have been testedas per IS:1237 - 1980 against control concrete for results showed that Nitoflor Hardtop improves theabrasion resistance of concrete by 225% and Nitoflor HardtopStandard by 150% when tested as per guidelines in IS.

3 1237- clauseNon metallic surface floor hardenerAll concrete floors shall be surfaced or broadcast with NitoflorHardtop/ Nitoflor Hardtop Standard , a non-metallic monolithicsurface floor hardening compounds containing rust free,hardwearing aggregates. The aggregates shall have a Moh'shardness of not less than 9 for Nitoflor Hardtop and not lessthan 8 for Nitoflor Hardtop strengthNitoflor Hardtop & Nitoflor Hardtop Standard shall possess aminimum compressive strength of 60N/mm2 & 50N/mm2respectively when tested as per IS: 516 - instructionsBase concreteThe base concrete should have a minimum cement contentof 300 kg/m3. The concrete mix should be designed tominimise segregation and bleeding.

4 Free water cementratios of less than (incase of Nitoflor Hardtop Standard )are required. The concrete should have a slump of between75 and 100 mm (incase of Nitoflor Hardtop ) and 50 and 75mm(incase of Nitoflor Hardtop Standard ).Use of Fosroc's water reducing admixture is base concrete should be laid and compacted in accordancewith good concrete practice. Accurate finished profile andminimum laitence build-up should be ensured. Particularattention should be paid to bay edges and corners to ensurefull Hardtop / Nitoflor Hardtop Standard are applied fordifferent types of industrial Wearrate (kg/m2)traffic use(IS:1237-1980) < >2 < > <4mmIt is recommended that the floor be marked off into bays ofknown area.

5 Sufficient material should then be laid out tomeet the required spread of Nitoflor Hardtop / Nitoflor Hardtop Standard canNitoflor Hardtop & Nitoflor Hardtop StandardNitoflor Hardtop & Nitoflor Hardtop Standardbegin when the base concrete has stiffened to the point whenlight foot traffic leaves an imprint of about 3mm. Any bleedwater should by now have Hardtop / Nitoflor Hardtop Standard are applied in twostages.(a) The first application is made using 50% to 70% of the totalmaterial. Nitoflor Hardtop / Nitoflor Hardtop Standard is evenlybroadcast onto the concrete surface. When the materialbecomes uniformly dark by the absorption of moisture fromthe concrete this first application can be floated.

6 Wooden floatsor, on large areas, the power trowel with disc may be used. Itis important, however, that the surface is not over worked.(b) Immediately after floating, the remaining Nitoflor Hardtop / Nitoflor Hardtop Standard is sprinkled evenly over the moisture is absorbed and the surface can be floated inthe same way as finishing of the floor using a power trowel can be carriedout when the floor has stiffened sufficiently so that damage willnot be of ApplicationThe timing of application Nitoflor Hardtop / Nitoflor HardtopStandard is important and critical. If applied too early, bleed orexcess water will wash away the cementitious content of theproducts, thereby making them ineffective. Also denseraggregates sink into the the application of Nitoflor Hardtop / Nitoflor Hardtop standardis done too late, there will not be sufficient water/moisture toabsorb the material into the concrete.

7 Material forcibly appliedand trowelled thus, will cause cracks on the surface later, asthere is no water/moisture to hydrate the edgesWhile applying Nitoflor Hardtop / Nitoflor Hardtop Standard atthe edges of the concrete floor or, at the end of bays, extraprecaution should be taken by way of sprinkling more materialand finishing it smoothly with a steel trowel. This is anadditional protection particularly to bay edges where the reactiondue to heavy or impact is felt have shown that proper curing of concrete floors treatedwith products such as Nitoflor Hardtop / Nitoflor HardtopStandard is essential to ensure the physical properties of most efficient method of curing by using Concure WB,curing membrane which conforms to ASTM and DOEspecifications.

8 However, in indoor applications where curingconditions are less arduous and breakdown of the membraneslower, alternative approved methods of curing such aspolythene sheeting or water ponding are to useNitoflor Hardtop / Nitoflor Hardtop Standard is supplied ready touse on site. Cement or aggregates should never be added toNitoflor Hardtop / Nitoflor Hardtop floorsWhen a coloured floor is required, it is strongly recommendedthat a job site trial area is treatmentsPenetration type surface treatments are recommendedto give low porosity and dust proof For concretes with optimised water cement ratios, NitoflorHardtop / Nitoflor Hardtop Standard shall not be broadcastin excess of 3 - 4 kg /m2.

9 For such applications, consultFosroc.
