About the product
Aguaplast Pro 6h is Beissier's high-performance insulating professional filler — the most advanced product in the Aguaplast range, with 50% more coverage than conventional fillers thanks to its hollow microspheres. In a single coat, it renews and smooths any surface, with simultaneous anti-condensation, thermal insulation, and acoustic insulation properties. The 6-hour working time version is best suited for large surfaces, teamwork, or low-temperature conditions — allowing more time to work without joints or marks. It withstands temperatures up to 100°C. 10 kg format.
What jobs and surfaces is it ideal for?
- ✓ Smoothing and renovation of walls in a single coat — large surfaces
- ✓ Thermal bridges — slab fronts, lintels, roller shutter boxes, pillars
- ✓ Walls with regular condensation or "cold wall" effect
- ✓ Acoustic improvement in restaurants, offices, and homes
- ✓ Insulation of heating pipes (withstands up to 100°C)
- ✓ Large projects where work is done in sections — 6h working time
Why choose Aguaplast Pro 6h
- ✓ 6 hours of working time — the longest working time in the Pro range; allows plastering entire walls without working joints, especially important for large, premium quality surfaces
- ✓ 50% more coverage per kg — the hollow microspheres make Pro much more efficient per kg than conventional fillers
- ✓ Anti-condensation + thermal insulation + acoustic insulation — triple function in a single product thanks to the hollow microspheres
- ✓ Renews and smooths in a single coat — covers textured finishes, patterns, and irregularities in one application; ideal for complete apartment renovations
- ✓ Withstands up to 100°C — suitable for walls in contact with heating or boilers
- ✓ Vapor permeable — does not seal the wall; vapor can escape outwards without accumulating in the wall

How to prepare and apply — in 4 steps
