Universal Bonding Primer Polymer Primer – for mineral substrates, 2.5 L can
The Universal Bonding Primer is a transparent, polymer-based pre-coating (primer) for all bitumen tapes. It binds dust adhering to mineral substrates, consolidates porous surfaces and creates a reliable bonding bridge – ideal for long-lasting, secure adhesion on concrete, stone, masonry and plaster.
Properties & Benefits
-
Good adhesion on almost all substrates – especially on mineral substrates
-
Fast drying of the applied primer
-
High dust penetration and dust binding
-
Improves bonding and ensures a strong connection between the bitumen tape and the substrate
-
Solvent-based
Application
As a pre-coating for bonding bitumen tapes to concrete, stone as well as porous, absorbent mineral substrates.
The primer is used to bind adhering dust and to create a bonding bridge.
Processing Instructions
a) Preparatory work
-
The surfaces to be bonded must be cleaned.
-
The substrate should be dry, sound and free from loose particles, grease and heavy soiling.
b) Application of the pre-coating
-
Apply the primer thinly and evenly (e.g. using a brush or roller).
-
Before applying the bitumen tapes, the pre-coating must be fully dry.
-
The primer should be smudge-proof when touched with a finger.
-
The primed surface must remain dust-free and dry to ensure an intensive bond (e.g. with concrete).
-
Avoid contamination of the dried primer with dust or water, as this can reduce adhesion.
Not suitable for
- Wood fibre insulation boards
