About EverGuard® TPO Seam Cleaner & EverGuard® TPO Low VOC Seam Cleaner

Used to clean exposed or contaminated seams prior to heat welding to remove any residual soap or to revitalize aged membranes.

Installation Options

  • Do not use on “bag fresh” material that has been exposed for less than twelve hrs. unless it has been contaminated.
  • Follow the guidance below for cleaning TPO 
  • Light Contamination — Membrane that has been exposed overnight up to a few days to air-borne debris, foot traffic, or dew or light precipitation can usually be cleaned with a white cloth moistened with EverGuard® TPO Cleaner.
  • Be sure to wait for solvent to flash off prior to welding.
  • Dirt-Based Contamination — Membrane that is dirt encrusted will require the use of a low-residue cleaner, such as Formula 409®, and a mildly abrasive scrubbing pad to remove the dirt. This must be followed by cleaning with a white cloth moistened with EverGuard® TPO.
  • Exposure-Based Contamination — Membrane that is weathered or oxidized will require the use of EverGuard® TPO Cleaner and a mildly abrasive scrubbing pad to remove the weathered/oxidized top surface layer. This must be followed by cleaning with a white cloth moistened with EverGuard® TPO Cleaner.
  • Unexposed membrane left in inventory for a year or more may need to be cleaned as instructed above.
  • Low VOC Seam Cleaner available for sale in the state of California and any other areas that require VOC content of < 250 grams/liter.
