Avoid using where rain is imminent or on wet surfaces. 


  • Remove the self-adhesive backing.
  • Put the band on the surface avoiding the formation of air bubbles between the butyl and the support.
  • For joints, overlap edges by at least 5 cm.
  • Apply at a temperature between 0°C and +40°C.
  • The product, once applied, must be covered within 24 hours.
