Next Generation Gutter Lining

ULTRAFLEX is designed to be used by industry professionals and used in conjunction with Ultraflex matting, the system forms a seamless membrane which can be applied to a variety of gutter surfaces such as Metal, Concrete and Asbestos, ideal for complicated gutter cross-sections.

Our Ultraflex Kit includes - Ultraflex Liquid, Ultraflex Matting & 4" Roller with Sleeve.

Application of wet-on-wet system

  1. Apply when ambient temperature is minimum of 2 degrees and rising and not exceeding 30°C.
  2. Ensure gutter substrate is in good condition, dry, clean and free from dust, moss or lichen.
  3. Ultraflex is self-terminating and can be started and stopped at any point along the gutter, if the gutter is in good condition, strike a line using tape on the gutter to coat up to (important: when the Ultraflex has been installed ensure the tape is pulled before the Ultraflex is dry). If the gutter is in poor condition a termination bar or flashing is required.
  4. Open tin and mix thoroughly before using.
  5. Apply Ultraflex straight out of the can onto the gutter substrate using a solvent resistant roller. Dry roll ULTRAFLEX MATTING into the product until the Ultraflex is drawn through, then immediately apply another coat of Ultraflex ensuring the matting is fully embedded avoiding any pinholes.
  6. It is advised to start at the end of the gutter including upstands to a minimum of 150mm (if possible), ensuring the matting overlaps any trims (including fixings) / joints / change of material by 50mm.
  7. Infill the remaining gutter length using the same method as above using Ultraflex matting, at a minimum coverage rate of 1.5kg per m2. The whole area including trims must be coated to form a continuous seamless membrane. Please take time to make sure no pin holes exist. Drying time will be approx. 2-8 hours depending on weather, fully cured in 24 hours.
    Coverage: A 15Kg drum of Ultraflex will cover 8 to 10 sqm depending on the surface. Please note this coverage may be affected by the contractor experience in applying Ultraflex system.
