Nitoflor Hardtop S 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 which is easy to trowel into the surface of fresh, wet concrete. Nitoflor Hardtop S cures 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 S is available in natural (concrete grey) colour as standard.


Nitoflor Hardtop S provides a highly abrasion resistant surface to fresh concrete floors 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 traffic, e.g. power stations, heavy industry, agricultural buildings, warehouse floors, loading bays and workshops.
