For pre-treating the surface when applying Würth butyl and bitumen tapes and window sealing tapes with butyl strips. Also suitable for Eurasol Thermo HT. Applying primer is required on porous and absorbent surfaces, such as concrete, gypsum, wood, masonry, aerated concrete, plaster, hardened cement paste etc., for optimum adhesion.
The surface must be dry and free from dust or grease. Remove paint residues, impregnation agents and concrete and cement skin.
Cover adjacent surfaces and the floor. Spray evenly on the surface; repeat the process on highly absorbent surfaces. Protect the sprayed surface from dust and moisture. Clean the spray head with Würth PU cleaner when not using the spray. The tape can be applied after the specified flash-off time.
