Nanoproofed® protection Stein & Holz

Suitable substrates: Concrete, lime sand brick, clinker bricks, sand brick, travertine, granite, mineral plaster with less than 5% organic binding material content.

It protects the substrate from wetting, is permeable towards water vapour, and thus prevents the treated parts from moisture expansion and rotting. When the roll-off effect decreases, it can be easily renewed.
