Description
The subsurface of the brick is dark-metallic. On the handmoulded brick a light grey to white top layer/coating is applied based on a cement mixture. The colour scheme is nuanced. The colour may change in humid conditions, and after drying out the cement coating will get its true colour. The colours shown are a near reflection of reality.
Pressure
The facade bricks (non-perforated) have five sand covered sides and one side with possible oblong groove. The structure looks rugged with fine and irregular grooves in the sandy surface. The baking process takes place in a gas-heated tunnel oven under slightly reduced atmosphere. The facing bricks of the KOLORO series have a cement coating. The remarks below may be useful for the correct and successful use in the brickwork.
