Note
The drying and the carbonation of lime is influenced by the environmental conditions: it is recommended to apply the product at temperatures between 10 and 35 ° C with humidity less than 75%. Avoid application under direct sunlight.
Exposure to low temperatures, high humidity, or rain may cause the surface to whiten.
