About the product
Aguaplast Pro 2h is Beissier's high-performance insulating professional filler — the most advanced product in the Aguaplast range, with 50% more yield than conventional fillers thanks to its hollow microspheres. In a single coat, it renews and smooths any surface, with anti-condensation, thermal insulation, and acoustic insulation properties simultaneously. The 2-hour working time version is best suited for fast-paced projects, small areas, or high-temperature conditions. It resists 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 — interior and exterior
- ✓ Thermal bridges — slab edges, lintels, roller shutter boxes, pillars
- ✓ Walls with habitual condensation or "cold wall" effect
- ✓ Acoustic improvement in restaurants, offices, and homes
- ✓ Insulation of heating pipes (resists up to 100°C)
- ✓ Concrete, cement, polystyrene, wood, plaster, and primed metals
Why choose Aguaplast Pro 2h
- ✓ 50% more yield per kg — the hollow microspheres make Pro yield much more per kg than conventional fillers; 10 kg covers surfaces that a standard filler would not reach
- ✓ Renews and smooths in a single coat — the formulation with microspheres is lighter and has a higher volume; it covers irregularities, textured finishes, and textures in a single application without the need for multiple coats
- ✓ Anti-condensation + thermal insulation + acoustic insulation — triple function in a single product; the microspheres reduce temperature and sound transmission while preventing surface condensation
- ✓ Resists up to 100°C — suitable for plastering walls in contact with heating or boiler pipes; it does not degrade or change properties at high temperatures
- ✓ Does not crack or shrink — dimensional stability after setting; no cracks appear even in thick layers; perfectly flat surface ready for painting
- ✓ Water vapor permeable — the wall treated with Pro continues to breathe; internal water vapor can escape, preventing it from being trapped in the wall
Compatible substrates
How to prepare and apply — in 4 steps
- Prepare the substrate: clean, sound, and free of dust, grease, and poorly adhered parts. On metals, prime with anti-corrosive. On highly absorbent substrates, apply Fixacryl.
- Mix: add water according to package instructions and knead until a homogeneous paste is formed. Working time: 2 hours at 20°C. Do not re-knead once setting has begun.
- Apply with a smooth trowel or spatula in a single coat for complete renovation, or in a localized layer for repairs. Very easy to work with and spread.
- Sand and paint: once dry, sand lightly and apply plastic paint or Lisomat Anti-Condensation to enhance the system. Clean tools with water.

Pro 2h vs Pro 6h — which one to choose?
Pro 2h: ideal for small areas, fast-paced projects, high temperatures, or when faster setting is desired. Pro 6h: ideal for large surfaces, teamwork, or low temperatures — the 6-hour working time allows more room to spread evenly without joints or marks. Both versions have the same technical properties.
