Viking Lybra SBS is suited to tricky / confined roofs where it can be 'bled' in to vulnerable areas such as tight corners and awkward areas susceptible to leaks such as roof penetrations, internal corners and gutter junctions.

It is suitable for low-slope roofs (flat or curved), gutters and parapets, waterproofing beneath a floating deck, inland and coastal conditions, commercial and residential buildings.
