Uniroc Top

‘Dry Shake’ floor hardener for new concrete floors


UNIROC TOP surface hardening compound is a 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. UNIROC TOP is easy to trowel into the surface of fresh, wet concrete and it cures to provide a dense, non-porous surface, which is extremely hardwearing and abrasion resistant. The monolithic nature of UNIROC TOP ensures that problems normally associated with ‘thin’ screeds e.g. curling, shrinkage, cracking etc. are completely overcome.


At water contents equivalent to those obtained in practical applications, the following results were obtained:

Compressive strength: 62 N/mm2 @ 28 days
Hardness (Mohs scale): 7.0
Abrasion Resistance: 225% of normal concrete


UNIROC TOP should be applied at an even application rate of 3.0 – 5.0 kg/m2. It is recommended that the floor is amarked into bays of known area. Sufficient material should then be laid out to meet the recommended spread rate.

Application of UNIROC TOP should begin without delay when the base concrete has stiffened to the point when light foot traffic leaves an imprint of about 3 to 6 mm. Any bleed water should now have evaporated, but the concrete should have a wet sheen.


UNIROC TOP provides a highly abrasion resistant surface to fresh concrete floors by the ‘dry shake’ method, which ensures a monolithic bond to the base concrete. It is ideally suited for all industrial areas, which are subjected to heavy traffic, e.g. warehouse floors, loading bays, workshops, heavy industry, and power stations.
