SURFACE PREPARATION:

Surfaces must be clean of dirt loose material, grease and oils. Rough or porous surfaces must first be treated with Webbseal Bitumen Primer.

APPLICATION:

Do not apply to very cold frosted surfaces. Trim the materials to the required length/shape allowing an overlap of at least 25 cm where the material is to be joined. On stepped flashing begin at the lowest level and work upwards. Warming the tape using gentle indirect heat will help the adhesion and make the tape more workable in cold temperatures. Ensure that there are no air pockets. Apply even pressure over the entire surface using a non-abrasive tool e.g. cloth or hand roller. Take care not to stretch or puncture the foil during application.
