Nitofloor Hardtop Standard Floor Hardener, 25 kg

Nitofloor Hardtop STDNon metallic, monolithic surface hardening compound Uses Nitofl or Hardtop Standard provide a highly abrasion resistant surface to concrete fl oors by the dry shake-on method which ensures that the hardwearing surface bonds monolithically to the base concrete. They are ideally suited for all industrial areas subject to the heaviest traffi c, e.g. loading bays, trucking lanes, car parks, workshops, machine shops, ramps and spillways. Advantages Non metallic - does not rust or stain. Provides a hard, abrasion resistant surface Forms monolithic bond with base concrete Easy and economical to apply Description Nitofl or Hardtop Standard is quality controlled, factory blended powder which are ready to use on site. They contain special hardwearing aggregates which have been selected for abrasion and wear resistant properties as well as shape and size. These latter considerations, together with the use of high performance workability admixtures, produces a material which is easy to trowel into the surface of fresh, wet concrete. Nitofl or Hardtop Standard cure monolithically to provide a dense, non-porous surface which is extremely hardwearing and abrasion resistant. Monolithic cure ensures that problems normally associated with thin ‘granolithic' screeds, viz., shrinkage, cracking, etc., are completely overcome. Being non-metallic, Nitofl or Hardtop Standard provide a nonslip surface which will never rust and disintegrate. Technical support Fosroc offers a technical service to specifi ers, end users and contractors, as well as on-site technical assistance in locations all over the country. Properties Abrasion resistance (IS : 1237-1980) Nitofl or Hardtop Standard has been tested as per IS:1237 - 1980 against control concrete for abrasion resistance. Test results showed that Nitofl or Hardtop improves the abrasion resistance of concrete by 225% and Nitofl or Hardtop Standard by 150% when tested as per guidelines in IS:1237 - 1980. Nitofl or Hardtop Standard are applied in two stages. (a) The fi rst application is made using 50% to 70% of the total material. Nitofl or Hardtop Standard is evenly broadcast onto the concrete surface. When the material becomes uniformly dark by the absorption of moisture from the concrete this fi rst application can be fl oated. Wooden fl oats or, on large areas, the power trowel with disc may be used. It is important, however, that the surface is not over worked. (b) Immediately after fl oating, the remaining Nitofl or Hardtop Standard is sprinkled evenly over the surface. Again moisture is absorbed and the surface can be fl oated in the same way as before. Final fi nishing of the fl oor using a power trowel can be carried out when the fl oor has stiffened suffi ciently so that damage will not be caused.
