How much gel do I need for 20 m²?
Updated: 15.07.2026

With an approximate consumption of 0.1 - 0.15 l/m² per layer, you need to calculate according to the number of layers.
Detailed answer
For Gela Cryl TR100, the usual estimate is about 0.10–0.15 kg/m² per layer. Finer Aqua Microconcrete tends to require less, while more textured Aqua Nature requires more. If the surface is more open, uneven, or significantly absorbent, it is worthwhile to allow a margin.
Common mistakes
- calculating material without a margin
- not accounting for substrate preparation and tools
- comparing price without the same layer composition
