Technical Leaflet Directions for use FLEX PU-50 S is a one-component, polyurethane adhesive sealing mastic with solvents, providing: • Resistance to temperatures ranging from -40oC to +90oC. • Excellent bonding to any kind of building material. • High elasticity. • Great endurance to aging (UV radiation and weather). • Dyeability after hardening, only with water-soluble paints. FLEX PU-50 S is suitable for sealing vertical and horizontal joints 5-30mm thick, on various materials like concrete, aluminium, steel, wood, glass, natural and artificial stones, etc., both indoors and outdoors. Also suitable for bonding these materials. In case of grouting on natural or artificial stones, such as marble and granite, please contact ISOMAT’s Technical Support Department. 1. Substrate preparation The substrate must be dry and free of dust, loose particles, grease etc. The joint should be cleaned with a paintbrush or wire brush and then air-blasted. To avoid undesirable soiling at joint edges, a self-adhesive paper-tape is applied along the edges and then removed immediately after sealing the joint (before a film is formed). 2. Application The cartridge is inserted in the special gun and the nozzle is cut slantwise, so that it does not fit into the joint but barely touches and slides along the edges. FLEX PU-50 S is applied by moving the cartridge along the joint axis at a 450 angle. While still fresh, the mastic is leveled with a trowel. Cleaning of tools: Tools must be thoroughly cleaned with common solvents, while material is still fresh. If material has hardened, tools may only be mechanically cleaned.
