RUNNING TRACKS POLTRACK ROLL-SANDWICH SYSTEM Synthetic outdoor system for running tracks. It is applied on fine asphalt or smooth, waterproof concrete, without rising humidity issues, with first layer a base layer of the prefabricated shock-pad ISOPOL 854, second layer (sealing layer) the colored polyurethane sealing material POLAPLAST P22 on top of the rolls, and third layer (surface layer) the full-PU colored polyurethane material POLAPLAST P20, before broadcasting EPDM granules on top to finish it off. Steps: 1. PU FLEX - Special, polyurethane adhesive. Used for the application of ISOPOL 854 shock-pads or other prefabricated shock-absorbent rolls made from recycled rubber or EPDM. Applied by V-notch trowel. 2. ISOPOL 854 - Shock-pad in rolls. Elastic, prefabricated shock-pad made of recycled rubber providing shock-absorbency. Used as cushion substrate before the application of polyurethane or acrylic systems. 3. POLAPLAST P22 - Colored polyurethane sealing layer. Applied by flat trowel. 4. POLAPLAST P20 - Colored, polyurethane full-PU, selfleveling surface layer. Applied by V-notch trowel and the parallel use of spiked roller. 5. Broadcasting EPDM granules in granulometry 1-3mm. Description PU FLEX 140 - Special, polyurethane adhesive. BASE LAYER ISOPOL 854 - Shock-pads in rolls. SEALING LAYER POLAPLAST P22 - Colored polyurethane sealing layer. SURFACE LAYER POLAPLAST P20 - Colored polyurethane full-PU surface layer.
