Surface Preparation

Before installation, the surface must be clean, dry and sound. Dust, oil, dirt and any residues that could reduce adhesion must be removed. Applying a suitable bitumen primer is recommended for stronger adhesion.

Pre-Installation Checklist

• The surface must be dry
• Voids and cracks must be repaired
• Sharp protrusions must be removed
• Primer application must be completed
• Negative water pressure must be checked

Gün Zirve Membrane Application Method

Gün Zirve membrane products are applied by the torch method. During installation, the underside of the membrane is heated in a controlled manner and firmly bonded to the substrate.

Installation Steps

1. Surface Preparation

The substrate is cleaned and bitumen primer is applied.

2. Membrane Positioning

The membrane rolls are positioned in the direction of installation.

3. Torch Application

The underside is heated in a controlled manner and bonded to the substrate.

4. Overlap Check

A minimum overlap of 10 cm must be provided at the seams.

5. Final Inspection

The welded areas and surface adhesion are checked.
