How to apply Cal Bonit
To ensure proper adhesion, prepare the surface before application. The substrate must be completely dry and clean, and free of loose particles, dust, mold, or efflorescence. Any damaged render must be repaired.
Apply a primer beforehand:
- For porous surfaces, use ECO PRIMER
- For non-porous surfaces, use ECO PRIMER PUENTE
Then apply Cal Bonit in a minimum of two coats, each with a thickness of 1 to 1.5 mm. Apply by hand with a trowel, allowing at least 24 hours between coats for drying. The result is a natural, resilient coating that does not require any additional products to achieve a high-quality finish.
Additional recommendations for using this product relate to ambient temperature and humidity levels. It is advisable to apply it at temperatures between 5°C and 30°C and with relative humidity between 50% and 80%.
Under no circumstances should it be applied in strong winds, direct rain, or when there is a risk of frost within the following 48 hours.
