Fosroc Nitoflor Hardtop Standard Floor Hardener Standard are 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. Nitoflor Hardtop / 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, shrinkage, cracking, etc., are completely overcome. Being non-metallic, Nitoflor Hardtop/Nitoflor Hardtop Standard provide a non-slip surface which will never rust and disintegrate.
