Agrément Case Study The product was applied to an existing surface at a rate of 0.4 manually by rollers. The drying l/m2 time, was 2 hours which is within the 4 hours limit, stated in the method statement (Figure 2). The results for the rejuvenated surface are listed in Table 6. a) Prior to treatment b) After treatment Figure 2: Product application Table 6: Testing for Agrément certification Proposed Untreated Property Treated Area Improvement Agrement Area limits After 3 Months
