Exterior panels made of stone

In Leusden there is a building that was built 3 years ago. The exterior panels are made of stone and, due to their rough surface, quickly absorb dirt and green deposits (algae), causing them to quickly become dirty after 3 years. Solution: clean and coat with our concrete/stone coating. In Leusden there is a building that was built 3 years ago.
