Fixative

While based on our best experience, the technical advice given should be considered purely as guidance, and must be confirmed through comprehensive practical tests. This does not relieve the purchaser of their responsibility to personally test our products to see whether they are suitable for the planned use
Preparing the surface:
Old bituminous membranes: Repair any uneven areas, tears, overlapping areas or folds in the surface, and remove any old protective paints. Cementitious substrates: Apply to solid, clean, dry surfaces. Remove any loose matter, oils, waxes, grease, dust and any peeling or flaking paint. Check the functionality of any water flow points
Mix the primer before use and apply undiluted using a roller or brush in the quantities indicated in the table according to the type of substrate. IMPELAST or IMPELAST FR may be applied between 4 and 24 hours later
