About the product
Fine lime finish, with a wall that continues to breathe
Kerakoll Biocalce Revoco Fino is a certified and eco-compatible natural smoother based on pure natural NHL 3.5 lime (according to EN 459-1) for the fine-grained finishing of renders. Its high breathability is key: it maintains vapor exchange between the wall and the environment, preventing condensation and humidity that appear when an old wall is sealed with cementitious or plastic products.
LIGHT MIX AND LONG WORKABILITY: it spreads quickly and allows time to smooth without rushing, which on large surfaces results in a uniform finish without visible work joints.
Why choose Biocalce Revoco Fino
- ✓ Natural, porous and highly breathable: lets the wall breathe and regulates humidity.
- ✓ Fine-grained finish with homogeneous mineral aesthetic.
- ✓ Light mix: fast and regular application, with less effort on site.
- ✓ Long workability and excellent surface fineness.
- ✓ Pure natural NHL 3.5 lime according to EN 459-1, suitable for heritage restoration.
- ✓ Interior and exterior, both in new construction and in rehabilitation and sanitation.
