Sewerage District Pump Station

Milwaukee, WI

Project: Strip up to 36 mils of lead-based paint and lead-based primer from structural steel, steel staircase (6 floors) and hand rails.

Conditions: High humidity area with steel temperatures varying from 48 F to 70F (spring to summer). Close quarters.

Discovery: Seven strippers were tested for ability to strip lead and to obtain optimum dwell time at varying temperatures.

33073 Enviro-Prep^® Chemical Stripper was selected:

* No VOC

* Not dangerous to the touch in the event of contact.

* Low LEL factor since work was being completed in a confined space environment that had active electrical switching gear and pumps.

* Lead stabilizing ability: XRF readings in the range of 5-28 micrograms per centimeter squared.

* It was the only product that took off multiple layers and the only non-caustic to cut through to coat.

Process: Product was brushed on and covered with .03 Mil plastic, allowed to work with an average dwell time of 12 hours then removed by wet scraper method.

Lab test: Once product was removed it was sent to the lab and returned with a TCLP result of 2 ppm, suitable for regular landfill disposal.

Contractor recommendation:

"This product worked extremely well and was easy to remove from corners and crevasses. We fully recommend it."
