Colour - the surface colour can differ (also, for a grey or unpainted pavement and edges) being wet or dry. The surface colour can also differ for pavement/edges manufactured in different time periods. In order to reduce the possible differences in the colour tones (both grey and colourful), it is recommended to use the paving stones from 3 different pads at the same time. Note - after some time of working with the surface the small colour differences will disappear.
Hair-cracks - in individual cases hair-cracks can appear in the surface. It can be noticeable when a wet surface is drying. Such cracks do not affect product’s quality or value and they do not reduce its usage options.
