Nitoflor Hardtop Standard

Non-metallic, monolithic surface hardening compound for fresh concrete floor.

Products Description:

Nitoflor 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.Nitoflor 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., shrink age, cracking, etc., are completely overcome. Being non-metallic, Nitoflor Hardtop Standard provide a non slip surface which will never rust and disintegrate.

Uses:

Nitoflor Hardtop Standard provide a highly abrasion resistant surface to concrete floors 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 traffic, 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

Specification clause:

1. Non-metallic surface floor hardener

All concrete floors shall be surfaced or broadcast with Nitoflor Hardtop Standard, a non-metallic monolithic surface floor hardening compounds containing rust free, hardwearing ag gregates. The aggregates shall have a Moh’s hardness of 7-8 for Nitoflor Hardtop Standard.

1. Compressive strength

Nitoflor Hardtop Standard shall possess a minimum compress Sive strength 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 minimize 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 Nitoflor Hardtop to have its first application.The base concrete should be laid and compacted in accordance with good concrete practice. Accurate finished profile and minimum laitance build-up should be ensured. Particular attention should be paid to bay edges and corners to ensure full compaction.Nitoflor Hardtop Standard is applied for different types of industrial use, and the application rates are given below.Application                                      Intended
rate (kg/m2)                                    traffic use

7.0                                                Heavy
5.0                                                Medium
3.0                                                Light

It is recommended that the floor be marked off into bays of known area. Sufficient material should then be laid out to meet the required coverage.Relative abrasion resistance (ASTM C779, Revolving disc method).The abrasion resistance of Nitoflor Hardtop standard has been tested as per ASTM C779 (Revolving Disk Method) to measure the depth of wear in mm.

Curing:

Tests have shown that proper curing of concrete floors treated with products such as Nitoflor Hardtop Standard is essential to ensure the physical properties of the floor.The most efficient method of curing by using Concore S, curing membrane. However, in indoor applications where curing con dictions are less arduous alternative approved methods of curing such as polythene sheeting or water ponding are acceptable.

Ready to use:

Nitoflor Hardtop Standard is supplied ready to use on site. Cement or aggregates should never be added to Nitoflor Hardtop Standard.

Coloured floors:

When a coloured floor is required, it is strongly recommended that a job site trial area is laid.

Surface treatments:

Penetration type surface treatments are recommended to give low porosity and dust proof property.

Estimating

Packaging

Nitoflor Hardtop Standard is supplied in sealed 25 kg HDPE bags.

Storage

If kept in original undamaged packing, the shelf life of Nitoflor Hardtop Standard should be atleast 12 months under normal warehouse conditions.
