WELDANO INVEX 3D

1. Preparation

Remove any dirt present on the surface of SOLITEX WELDANO 3000 by wiping with a cloth, for example. Adhesion to frozen membranes is not possible. There must be no water-repellent substances (e.g. grease or silicone) on the membranes. Subsurfaces must be sufficiently dry and stable.

2. Cut to size

Cut WELDANO INVEX 3D down to the required strip length.

3. Weld the lower 3D sealing strips to the membrane

Weld the two lower WELDANO INVEX 3D sealing strips to the underlay membrane using either the WELDANO TURGA (HS) solvent welding agent or else hot air welding.

The effective joint width (area covered with solvent welding agent) must be at least 5 cm (2") wide and must extend as far as the edge of WELDANO INVEX 3D. Use a roller to secure the welded joints.

4. Weld the upper 3D sealing strips to the membrane

Weld the two upper WELDANO INVEX 3D sealing strips to the underlay membrane using either the WELDANO TURGA (HS) solvent welding agent or else hot air welding.

The effective joint width (area covered with solvent welding agent) must be at least 5 cm (2") wide and must extend as far as the edge of WELDANO INVEX 3D. Use a roller to secure the welded joints.

5. Weld the overlaps

Weld four overlap joints between the individual WELDANO INVEX 3D sealing strips using either the WELDANO TURGA HS solvent welding agent or else hot air welding.

The effective joint width (area covered with solvent welding agent) must be at least 5 cm (2") wide and must extend as far as the edge of WELDANO INVEX 3D. Use a roller to secure the welded joints.

6. Seal to skylight

Seal the WELDANO INVEX 3D sealing strips to the skylight using TESCON VANA.
