Acidified concrete finishes

Acidified concrete finishes have had the top layer of fine mortar removed with acid. The result is an artificially roughened finish on the architectural concrete from which only a small amount of the skin of the cement has been taken off. The depth of acidification determines the colour of the concrete: Coarser aggregates are only exposed to a very limited extent, the fines in the concrete determine the colour.

Acidification determines the colour

By drawing on their great skills and many years of experience, our experts at our plant for precast concrete are able to realise the finish that you desire.
