Bostik 3071 Spray Cork Cork-Colored – 500 ml Sausage Pack

Bostik 3071 – Solvent-Free Spray Cork for Sound and Thermal Insulation

Bostik 3071 is a high-quality, one-component spray cork for sound and thermal insulation of connection joints. The tough-plastic and non-sagging sealant consists of cork granules and a solvent-free, elastic binder.

The numerous air-filled cells of the cork granules reduce heat and cold transfer and simultaneously provide effective sound insulation. This makes Bostik 3071 particularly suitable for connection areas on windows, doors, and partition walls.

Suitable Substrates

The bonding surfaces must be firm, load-bearing, clean, dry, and free of grease and dust. The substrates must not contain bitumen or tar. For plastics and coated surfaces, adhesion and material compatibility should be checked beforehand.

Processing

1. Thoroughly clean and prepare the substrate.
2. If necessary, use a suitable primer.
3. Apply Bostik 3071 into the joint with even pressure.
4. Fill the joint completely and without voids.
5. Immediately smooth the surface with a moistened tool.

After complete curing, the spray cork should be sealed on the exterior and interior with a suitable elastic joint sealant and protected from direct weathering.

Technical Data

Calculate Consumption

Material consumption can be approximately calculated with the following formula:

Joint width in mm × Joint depth in mm = Consumption in ml per linear meter

For a joint cross-section of 10 × 10 mm, a 500 ml foil pack is sufficient for approximately 5 linear meters.
