Can PreMark® be applied on top of paint or tape?
PreMark® should not be applied on top of tape. PreMark® may bond to the tape but the tape may not have a proper bond to the road surface. The performance of the PreMark® will be directly related to the adhesion of the tape. During the application of the PreMark®, the heat will adversely affect any bond the tape may have with the road surface. Paints will become a barrier between PreMark® and the road surface. The rule of thumb is PreMark® should not be applied on top of paint. However, there are a few exceptions. If the paint is just a thin mist and the bitumen will “pop through”, then the PreMark® will work. In addition, if most of the paint is worn away, the application will work assuming that the PreMark® and the bitumen are able to combine. Prior to attempting to apply PreMark® on a painted surface, heat a small area and observe whether the bitumen comes through the paint. If it does not, remove the paint by heating it or grinding it off. If the bitumen does come through, then the
