FOSROC Nitoflor Hardtop Natural

Monolithic surface hardening compound for fresh concrete floors
Nitoflor Hardtop surface hardening compound is a quality controlled, factory blended powder which is ready to use on site. It consists of special hard wearing aggregates selected for their physical properties of abrasion and wear resistance, Portland cement and special additives to improve workability.This combination produces a material Nitoflor Hardtop cures monolithically to provide a dense, non porous surface which is extremely hard wearing and abrasion resistant. Monolithic cure ensures that problems normally associated with thin ('granolithic') screeds, e.g. curling, shrinkage, cracking, etc. are completely overcome. Nitoflor Hardtop is available in natural (concrete grey) colour as standard. Special colours, including Brick Red and Green can be produced on request for large orders.
Uses
Nitoflor Hardtop provides a highly abrasion resistant surface to fresh concrete foors by the dry shake method which ensures that the hard wearing surface bonds monolithically to the base concrete. It is ideally suited for all industrial areas subjected to heavy trafic, e.g. power stations, heavy industry, breweries, agricultural buildings, distillation plants, laboratories, abattoirs, warehouse floors, loading bays and work shops.
Advantages
- Supplied ready to use - no additives required
- Provides a hard, abrasion resistant surface
- Forms monolithic bond with fresh concrete base
- Hard, dense surface resistant to oils and grease
- Available in a range of colours to improve working environment
- Non-metallic aggregate - will not rust when wet
Technical support
Fosroc ofers a comprehensive range of high performance, high quality fooring, jointing and repair products for both new and existing foor surfaces. In addition, Fosroc ofers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance in locations all over the world.
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 control bleeding, although some limited bleed is desirable to ensure sufficient moisture is available to wet out the Nitoflor Hardtop when it is first applied. The use of water reducing admixtures from the Fosroc Conplast* range is strongly recommended in order to achieve a water:cement ratio below 0.55. The base concrete should have an on-site slump of between 75 and 100 mm. The base concrete should be laid and compacted in accordance with good concrete practice, taking care to ensure accurate finished profile and minimum laitance build up. Particular attention should be paid to bay edges and corners to ensure full compaction of the base concrete - see application instructions. Vacuum dewatering is not recommended.
