Urethane Conditioner 1421-A can be sprayed or manually applied by brush. A uniform application will insure more consistent protection. The amount of material required will depend upon the area of use and anticipated amount of "2K" overspray. The “2K” urethane and 1421A is removed from the surface with an application of PC-47-LT-1 urethane paint stripper. The PC-47-LT-1 is allowed to penetrate the urethane and the conditioner, then rinsed with either high or low pressure water. In cases of severe build-up, higher water pressure rinses will yield better results.
