Occasionally, at the beginning of use, a whitish coating may appear on the surface of the stones. This is a salt film drawn to the surface by evaporating moisture. Calcium salts are naturally present in the stone chips used to form the surface, which provide the product's authentic, natural appearance.
Why does this happen?
This phenomenon is rare and occurs exclusively with products manufactured during the autumn-winter period that have not yet been exposed to warm weather. These deposits form due to a specific combination of two weather factors: high humidity (rain or dew) and a simultaneous drop in temperature.
How to remove it
The coating disappears without a trace under the influence of heat—for example, during warm, sunny weather. To remove white marks quickly, you can heat the affected areas with a hairdryer:
-
Heat Gun (Industrial): Removes efflorescence in just a few seconds.
-
Standard Hairdryer: Takes slightly longer but is equally effective.
Once treated with heat, the coating does not reappear, and the surface remains unchanged for decades. While small, localized white spots usually vanish naturally as the ambient temperature rises, more intense or dense deposits require manual heating.
Our Production Standards
During manufacturing, we apply a double heating cycle (approximately 70°C for 8 hours). While this process typically prevents the issue, the effect may still manifest in rare cases during the initial stages of outdoor use.
Video Demonstration: This video shows the process of removing high-intensity white residue using a heat gun. In cases of such high intensity, natural sunlight alone would not have been sufficient to clear the surface.
