TEXSELF 1.5 is a membrane, in which the upper side acts as both a reinforcement and non-stick film. It is a high density, very stable, cross-laminated polyethylene film, with great tear resistance and magnificent mechanical properties.
· Extremely simple application: applies quickly, cleanly, and without the need for additional tools.
· Easy adherence to the substrate after applying the asphalt primer.
· Overlaps are carried out by simple contact and pressure.
· No blowtorch needed; TEXSELF 1.5 application only requires a brush, cutter and rubber roller.
· Safe to install; minimal risk of fires because no flame is used.
· Flexible membrane that easily absorbs the movements of the roof.
• Waterproofing of underground walls
• Waterproofing of non-drinkable water tanks
• Details flashing in pitched roofs
• Reinforcement of waterproofing on pitched roofs subject to filtering as a result of rain and wind, or the accumulation of snow or ice on roofs, especially lowpitch roofs and on gables.
• It can be used as both a underlay or reinforcement
layer for waterproofing systems with bituminous shingles.
• Capillarity barrier in partially buried walls to stop rising water
• As a vapour barrier in both conventional and deck roof systems.
· SUPPORT: The surface where it will be applied must be free of dust, loose or poorly adhered materials, oily or non-stick residue and any soil in general. It may be applied on concrete, wood and fretwork sheet supports; an adherence test must be conducted on all other surfaces.
· Primer: For better adherence of the membrane, apply EMUFAL I to the support, allowing to dry completely, approximately 24 hours. For flat and cohesive surfaces: metal, plastic, solid wood surfaces, priming may not be necessary. We recommend conducting a test beforehand in order to verify adherence.
· Remove the non-stick silicone film from the lower side and apply the membrane to the previously primed surface.
· Press the membrane against the substrate with a brush, from the center toward the edges, in order to prevent bubbles from forming.
· The overlap will be 8 cm, and will be carried out by pressing firmly (once the silicone film is removed) on the upper membrane with a roller.
· TEXSELF 1.5 must not be applied when temperature is below 5ºC. If cold, windy, or humid, heat lightly.
· TEXSELF 1.5 must not be exposed to the elements; the membrane must be protected from the sun. The wear rate when exposed depends on the specific application conditions.
· Installation and measurements will be conducted in accordance with regulations of the UNE 104401 standard.
