A single part mortar with fine granulometry that forms a highly protective and fine finish ON concrete. The thixotropic polymer based DU FINE has correction range of thicknesses from 1 to 10 mm and has monolithic compactness & dimensional stability.It is impermeable to rains and has calibrated shrinkage. The fluidifying agents reduces watercement ratio while interstitial crystallizing agent provide stable chemical structure that is resistant to carbonation, nitrates, sulphates and chloride attacks.
