List of questions

A low level of blooms is common during the execution or roof setting, although they have taken all necessary precautionary measures.

Roof tiles may not contain salts (this is proofed in our products by the continuous analysis), but they can also appear in mortars or water.

All these effects will come out sooner or later and it would be better if they appear during setting of the roof, because it can be easily cleaned.

So our recommendation is simply wash with water and then let the roof drying until blooming stop appearing.
