Firestone QuickPrime Plus is designed to clean and prime PondGard EPDM liner/membrane prior to application of QuickSeam products where required by Firestone Specifications and Details. QuickPrime Plus must be applied with a QuickScrubber or QuickScrubber Plus pad and handle when preparing PondGard membrane liner to receive QuickSeam Tape products. Coverage is 50-100 linear feet when using with 3 or 6 wide tape Method of Application: 1. Splice surfaces must be clean, dry, and free of foreign materials and excess dusting agent. Clean with broom or rags to remove contaminates. 2. Stir QuickSeam Plus thoroughly before and during use. Apply QuickPrime Plus at the rate of 200 - 250 square feet per gallon (4.91 -6.14 square meters per liter) per side to the splicing surfaces using the QuickScrubber or QuickScrubber Plus pad and handle. 3. Use back and forth strokes with heavy pressure along the length of the splicing area, until membrane surfaces become dark gray in color with no streaking or puddling. 4. Additional scrubbing is required at factory seams, areas of excess dusting agent, or other contaminated areas of the Rubber Liner membrane. Change pads every 200' (61 m). 5. When using the QuickScrubber or the QuickScrubber Plus pad and handle, factory seams require parallel as well as perpendicular application motions along the factory seam. Apply sufficient pressure on the QuickScrubber Plus pad and handle during application so the pad holder flattens to allow the total surface of the pad to contact with the RubberGard membrane. 6. Allow the surfaces to dry according to the touch-push test (usually less than 10 minutes) before applying QuickSeam products or Splice Adhesive SA-1065. 7. Complete seaming procedures per Firestone's Specifications and Details Storage: Store in original unopened containers indoors at temperatures between 60 F (15.6 C) and 80 F (26.7 C). Do not store on roof in direct sunlight or at temperatures above 80 F (26.7 C).
