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