- Do not apply in adverse weather conditions as the product can be washed away by rainwater;

Support and application of bituminous waterproofing sheath
The substrate to be treated must be dry and clean; the humidity of the substrate could generate product bubbles. The surfaces that are dusted must be treated with a suitable primer to avoid the detachment of Extralarge.
The friable and non-adherent parts must be eliminated. On damp substrates, in order to avoid the formation of bubbles, it is necessary to apply suitable exhalers to eliminate the condensation that forms under the waterproof covering (1 exhalator every 50m2).
It is essential to carry out a perfect cleaning of the substrate to be coated and then use a suitable primer, i.e. diluting EXTRALARGE by 20-30% and applying it as a paint, 250 gr. per sqm. For all applications on reinforced concrete or similar surfaces, where the presence of metal normally produces micro cracks every 4/5 meters, the use of a polyester reinforcement is always required.
For the restoration of old waterproofing with bituminous sheaths in rolls that show considerable cracks, it is not possible to use EXTRALARGE without the reinforcement.
To avoid unsightly micro-lesions and to always have optimal workability, it is advisable to refrain from applying the product during the sunniest hours of the day.
