Restoration of natural stone - in the case of natural stone the very important factors are not only the shape, colour and structure of the surface, but also the chemical and physical properties. The materials we use are products of high-quality and fine-grain allowing to restore and repair soiled and damaged elements of natural stone, and even its imitations on artificial surface, e.g. concrete. The renovated surfaces can be additionally protected with special impregnates against dirt and moisture, which also facilitate cleaning.
