• Easily removes dirt and other contaminants from EPDM and TPO membranes.
• Prepares EPDM membrane for application of primer, adhesives, and tape.
• Prepares aged or contaminated TPO membrane for welding.

Single-Ply Membranes

1. Remove as much loose material as possible from the membrane surface where the adhesive or pressure-sensitive product will be applied by brooming or wiping the area with a dry rag. Extreme conditions of accumulated dirt may require a low sudsing detergent and water cleaning (rinse area thoroughly with CLEAN water and allow to dry).
2. Saturate a clean dry rag with weathered membrane cleaner. Scrub the area in a circular motion. Continue to clean the area, changing wipes frequently, until the surface is a consistent color with no streaking. Additional cleaning is required at factory seams (scrub parallel to the seam). Allow to dry.
3. Apply primer according to product instructions and/or roofing system specification.

Safety Information

• • Review the applicable Material Safety Data Sheet for complete safety information prior to use.

• Weathered Membrane Cleaner is EXTREMELY FLAMMABLE. This product contains materials that are fire and explosion hazards when exposed to heat, flame, or sparks. Store and use away from all sources of heat, flame, or sparks. Do not smoke while applying. Do not use in a confined or unventilated area. Vapors are heavier than air and may travel along the ground to a distant ignition source and flash back. A red caution label is required when shipping.
• During application, efforts must be made to prevent fumes from entering the building via air ventilation ducts. Do not place open containers or mix adhesive near fresh-air intake units. When possible, shut down or seal off the closest units. Avoid breathing vapors. Keep container closed when not in use. Use with adequate ventilation. If inhaled, remove to fresh air. If not breathing, perform artificial respiration. If breathing is difficult, give oxygen. Call a physician immediately.
