The sealant that bonds to bitumen

Thanks to its special formulation, 390 Spengler is ideal for roof applications. The solvent-based acrylate adheres perfectly to metal, wood and concrete without a primer. The sealant can also be used on slightly oily or damp surfaces, is easy to process and can be painted over with different paint systems. The use of bitumen is also no problem in combination with 390 Spengler.
