ISOSolve Gel is used as received. It can be applied by brush, roller or spray to floors, walls, ceilings or different types of molds. The viscosity allows the stripper to stay in contact with the coating for an extended period of time. Removal time will vary depending upon the type of material being removed, the thickness of the material and the application temperature. Coatings that are difficult to remove may require more dwell time, possibly as much as 24 hours. A second coat may be required. In this case, remove as much material as possible by scraping, wiping or water rinsing. When dry of residual water, apply another coat of the gel. Prior to any use, test the compatibility of ISOSolve Gel with the substrate being stripped.
