Primer spray
PRIMER
High-performance primer in spray form. Used as a base coat before applying adhesive tapes and sealants on loose, absorbent, fibrous, sandy, and other surfaces with poor adhesion. Features high coverage efficiency, quick-drying properties, strong bonding with the substrate, and resistance to aging. The rotating nozzle tip facilitates application. Suitable for both outdoor and indoor use in well-ventilated areas.
Advantages:
- Extremely increases the adhesion of sealing tapes
- Quick and easy application
- Clear

Application and technical data
To ensure effective bonding, make sure the surface is hard, dry, clean, and free from dust and grease. Compatibility tests of the materials to be joined are required. Apply Eurovent® PRIMER evenly onto the substrate, holding the can at least 20 cm away from the surface. Depending on the material used, allow 5-15 minutes for ventilation. Repeat this process for highly absorbent surfaces. Protect sprayed surfaces from moisture, dust, and contaminants. After each spraying procedure, turn the can upside down and continue spraying until only the propellant is released. This prevents the spray nozzle from clogging with adhesive residues. Clean any adhesive residue from the nozzle tip. The valve can be adjusted to three different levels. The spray nozzle can also be adjusted between horizontal and vertical spray patterns.

System products
To ensure maximum performance of the Eurovent® PRIMER, it is recommended to use it as part of a complete system together with:
- Eurovent® sealing and adhesive tapes, which – when applied with PRIMER – achieve enhanced adhesion to difficult substrates and provide increased durability of bonded joints,
- Eurovent® roof membranes (roof underlays / roof membranes), where PRIMER supports proper surface preparation prior to bonding tapes and sealing elements,
- Eurovent® vapour control membranes (vapour barriers), which require appropriate substrate preparation to guarantee full airtightness and vapour tightness of the internal layer,
- Eurovent® installation accessories, designed to work within the sealing system, ensuring durability and structural stability of all roofing details.
The use of complete Eurovent® system solutions guarantees maximum tape adhesion, effective moisture protection and long-term durability of the entire roof structure.
