“Evrika” is a hot-applied mastic of polymer-modified roofing bitumens with a mineral filler; before use it is heated to 160–180 °C. On roofs it is used to fill cracks and potholes in screeds and slabs, restore the chippings, seal outlets and junctions with pipes, and bond roll materials. Off the roof, the mastic is used to coat steel structures, concrete blocks, columns and pipelines in contact with the ground. The softening point is not lower than +105 °C, elongation is at least 1100%, and it is supplied in 30 kg bags.
