Definition

Cement based, fine, white, surface smoothening putty formulated for smoothing the uneven concrete and mineral surfaces, filling up the hair cracks and for covering interior and exterior surface defects

Usage Areas

For smoothing the uneven concrete and mineral surfaces, for filling up the hair cracks and for covering the surface defects due to removal of blistered old coating.

Package

5 kg polyethylene and 20 kg multi-ply paper bags

Features

Forms very strong, non-dusting and smooth surfaces, thus contributes to the appearance and the resistance of the top coat. Resistant to water and to moisture; when dampened, does not soften or does not weaken the adherence of the top coat to the substrate. Compared to gypsum panels and gypsum basedmaterials, has higher durability and adherence strength therefore more resistant against cracking. Reduces paint consumption by decreasing the absorbency of the surface. Having high filling capacity, at most 2 layers will be sufficient to achieve a smooth surface. Easy to apply. Easy to sand, non-dusting. Does not prevent the water vapour permeability of the wall.
