FIBSEAL PUR UF HY is a high elongation two-component hybrid polyurea spray system, specifically formulated for crack-bridging applications. Polyurea-based systems are characterized by their fast cure and high-performance properties and are therefore used in various coating and non-coating applications (waterproofing, protective, sealing, …). It can be applied to a thickness of 1–5 mm in a single application. FIBSEAL PUR UF HY can be apply exterior below-grade or between-slab. It protects structure from water penetration. It permits expansion and contraction of the substrate. It has a wide service temperature range and hence it is suitable for all climates. It resists bacterial attack, many acids, alkalis and salts. It forms a seamless membrane and hence eliminates overlapping, seaming and precutting.
