The surface of the substrate must be dry, properly cleaned, free from any debris and friable or detached parts. All substrates must have a degree of humidity not greater than 5%. The surface temperature during application must be at least +5° C above dew point. If necessary, depending on the surface, the following interventions are recommended:
Any contamination (water, dirt, dust, etc.) will have to be carefully removed before coating.
