areas of application
BORNIT® 5M-Primer is indispensable for the pre-treatment of bitumen layers to be applied hot as well as for laying roofing membranes and welded sheeting. BORNIT® 5M-Primer adheres to concrete, masonry, plaster and almost all other substrates common in construction as well as to grease-free metal.
BORNIT® 5M-Primer is not suitable for application on expanded and extruded polystyrene.
Note: According to Circular 11/05 of the German Building Trade Association (Bau-BG), emulsion-based bitumen primers (e.g. BORNIT® Speedbit-Primer) are expressly recommended for work indoors!

type and properties
BORNIT® 5M-Primer is an extremely fast-drying, brush-on and spray-on, solvent-containing bitumen-based primer.
BORNIT® 5M-Primer is used when short drying times are required to thus achieve faster work progress.

  • extremely fast-drying
  • universally applicable, therefore a multitude of possible applications
  • good adhesion properties
  • economical and cost-cutting, due to fast work progress
  • high penetration capability into the substrate
  • low effort and equipment and material expenses

The substrate must be dry, clean and free of frost and grease. Loose components, damaged concrete and plaster areas as well as cracks and holes must be repaired beforehand.

The substrate must be dry, clean, frost-free and free from grease. Loose particles, defective concrete and plaster as well as cracks and holes must be removed or repaired, resp., in advance.
BORNIT® 5M-Primer is applied by brushing, rolling or spraying it onto the substrate. Only perform subsequent work after complete and thorough drying! BORNIT® 5M-Primer is manufactured ready for use.
Do not apply indoors! For the indoor area (e.g. floor sealing with welded sheeting), we recommend the solvent-free bitumen primer BORNIT® Speedbit-Primer.

approx. 0.2 l/m² (depending on absorbency and structure of the substrate, consumption may vary upwards or downwards, resp.).
