Fosroc Nitoflor Hardtop Standard Floor Hardener

Product Details:

Non metallic, monolithic surface hardening compound for fresh concrete fl oor 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  Supplied ready to use, no additive required  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 quartz-silica 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 off ers a technical service to specifi ers, end users and contractors, as well as on-site technical assistance in locations all over the country. Colour : Green & Grey Properties Abrasion resistance (ASTM C779, Revolving Disc methods Nitofl or Hardtop Standard has been tested as per ASTM C779, Revolving Disc method against control concrete for abrasion resistance. Nitofl or Hardtop Standard Specifi cation clause Non metallic surface fl oor hardener All concrete fl oors shall be surfaced or broadcast with Nitofl or Hardtop Standard, a non-metallic monolithic surface fl oor hardening compounds containing rust free, hardwearing aggregates. The aggregates shall have a Moh’s hardness of 7-8 for Nitofl or Hardtop Standard. Compressive strength Nitofl or Hardtop Standard shall possess a minimum compressive strength of of 64N/mm2 in 7days and 75N/mm2 in 28days as per ASTM C109. Application instructions Base concrete The base concrete should have a minimum cement content of 300 kg/m3 . The concrete mix should be designed to minimise segregation and bleeding. Although there should not be any bleed water, but a wet “sheen” can still be clearly seen on the concrete surface, is the ideal situation for Nitofl or Hardtop to have its fi rst application. The base concrete should be laid and compacted in accordance with good concrete practice. Accurate fi nished profi le and minimum laitance build-up should be ensured. Particular attention should be paid to bay edges and corners to ensure full compaction. Nitofl or Hardtop Standard is applied for diff erent types of industrial use, and the application rates are given below. Application Intended rate (kg/m2 ) traffi c use 7.0 Heavy 5.0 Medium 3.0 Light It is recommended that the fl oor be marked off into bays of known area. Suffi cient material should then be laid out to meet the required coverage. Relative abrasion resistance (ASTM C779, Revolving disc method). The abrasion resistance of Nitofl or Hardtop standard has been tested as per ASTM C779 (Revolving Disk Method) to measure the depth of wear in mm.
