Substrate Preparation

All surfaces (joint flanks) must be load bearing, flat, dry and free of all residues that could prevent a good adhesion (such as oils, greases, loose parts). In wide façade joints with strong absorbent substrates, prime the joint edges  for hydrophobation before installation.


1.02 m per m joint plus offcuts plus 5 cm for each window sill side.
Depending on conditions at site. The exact consumption is best established by trials at site.

Application Conditions

Optimum processing temperatures: +8 ° C to +20 ° C. The expansion of the compressed foam is faster at higher temperatures and slower at lower temperatures.


When cutting the tape, add at least 2 cm per meter of measured length (plus 5 cm for each window sill side when using it on window-hole ledges).

Cut the joint sealing tape blunt and stick it onto the back site of the screw-hole ledge of the window sill. Guide it about 5 cm around the corners of the board profile.

Expansion starts immediatelly after decreasing the pressure of the rolled tape.
Take care for a perfect sealing layer while placing cut ends blunt together.

Note: Put a weight on remaining rolls in open boxes to prevent the rolls from expanding sidewards (telescoping). If necessary, joint sealing tape clips can help.


Disposal according to official national and regional regulations.
