We clean stone areas by sandblasting. This is an effective way to get rid of dirt and to reach places that are difficult to reach when cleaning by yourself. After this treatment, the surfaces are smoother and more susceptible to e.g. painting or renovation. We use pressure equipment and materials of varying degrees of hardness. In order to minimise the risk of damage, we select the pressure and degree of hardness of the cleaning materials, taking into account the degree of soiling and the type of stone. Sandblasting can be performed on materials such as sandstone, old brick, clinker, marble, granite and concrete.
