VASTR® Ultraflex is easy to cut with the MG Scissors PRO. Both lengthwise and widthwise, cut the VASTR® Ultraflex to size. Determine the desired roll width and color and process the VASTR® Ultraflex in a shingle fashion to ensure drainage. Remove the protective foil on top of the product. Slightly cut the release membrane on the back so that you can remove it in sections, revealing the self-adhesive layer. Provide a dry and dust-free surface and attach the Ultraflex by pressing firmly into place. When attaching VASTR® Ultraflex to an uneven surface such as a wavy tile roof, apply it to the high points first. Remove remaining release membrane and gradually press the VASTR® Ultraflex into the gaps to create a fully formed seal and bond. If the substrate is wet, the Ultraflex can first be worked with an (electric) burner so that the moisture evapourates. For highly absorbent substrates such as concrete pans, it is recommended to first apply a strip of double-sided VASTR® Butyl tape where the VASTR® Ultraflex can be pressed in.
