Repairing CIM is very easy, but special attention should be paid to the preparation of the area. Whether the area is large or small, the surface preparation is the same. When repairing CIM, the coating needs to be severely abraded. It is important to abrade six (6) inches out on each side of the area needing repair. Abrasion can be achieved either by using a surface grinder or wire brush. Acceptable adhesion may only be achieved though aggressive abrasion. Once the CIM surface has been abraded, the area needs to be solvent wiped with MEK or Xylene to provide a clean surface for the application. The MEK or Xylene needs to flash off before a light mist of CIM Bonding Agent is applied to the area. Allow the CIM Bonding Agent to flash off and apply the CIM coating within one (1) hour. The patched area, once cured will maintain the properties of the original coating leaving no seams. Additional information regarding this procedure can be found www.cimindustries.com/contractor-info.CIM industrial coatings can also be used to repair other liner systems that have failed. When repairing other coatings and adhesion test shall be conducted before the repair work is done. The test is needed to ensure that the CIM has the desired adhesion to the existing liner. While the patch may adhere to the existing liner satisfactorily, it is also important to make sure the existing liner is adhered well to the substrate. Once the adhesion test is done and the desired result are achieved, the rest of the procedure is the same as discussed above.
