- Fleece edges embed into wet liquid membrane while the central rubber zone remains unbonded
- Water pressure resistance of 3 bar
- Temperature resistance from -20°C to 90°C
- Not compatible with solvent-based materials and not suitable as a UV-exposed joint seal
Application Guide
- 1. Confirm that the selected Gripset liquid membrane is suitable for the substrate, exposure and joint movement.
- 2. Prepare the substrate and complete any required priming in accordance with the membrane TDS.
- 3. Measure and cut the joint band for wall-to-floor junctions, abutments and movement-joint details.
- 4. Apply the first membrane coat approximately 150 mm up the wall and onto the floor or adjoining substrate.
- 5. Embed the polyester fleece edges into the wet membrane and fully wet them out, removing all trapped air.
- 6. Leave the rear central rubber section unbonded so the flexible zone can accommodate movement.
- 7. Use a minimum 50 mm overlap where band lengths are joined. Use the specified Elastoproof 90° and 270° prefabricated corners where available; otherwise cut and fold the bottom leg while keeping all fleece fully bonded.
- 8. Complete the remaining membrane coats in accordance with the selected membrane TDS.
- 9. Apply only when the surface temperature is between 5°C and 30°C. Do not use solvent-based materials and do not leave the band UV exposed externally.
