Technology and characteristics
The principle of concrete lasuring as used in the examples shown here is based on a strongly diluted, usually semi-transparent, thin layer of colour on a silicate basis. Lime-resistant mineral and metallic oxide pigments are used. Usually several layers are applied, using a lasuring brush. Compared to normal concrete paint, the special effect of this technique lies in the mineral matte surface, which does not appear to be a separately applied layer. The concrete appears to be coloured rather than painted. The transparency of the lasur allows the dynamic colour of the concrete surface to shine through. The heterogeneous suction of the concrete is caused by the irregular distribution of additives, which in turn results in differences in pigmentation and thus an increase in the uniqueness of the concrete.
The overall appearance does not emphasise any optical flaws and irregularities that may occur. This is because such flaws are seen as dark/light contrasts, which are reduced by the application of the pigment. Individual areas can be given special treatment during application, which takes place in several layers.
