USAGE INSTRUCTIONS

Cut the tape approx. 3% longer than the joint length.
Do not use the tape roll's first and last 3 to 5 cm.

Remove the protective film.

Glue the tape about 2 to 3 mm from the joint edge. The tape will then start slowly to expand and fill the joint.

Do not glue the tape through corners. Instead, cut the tape strips to the correct length and press the tape ends together at a right angle. Do not overlap the tape edges.

If needed, use a putty knife to fasten the tape correctly.

Tips

• Surfaces to be sealed must be clean, dry and free from any dust, loose particles and oil stains.
• To guarantee an airtight connection, choose the tape size according to the width and depth of the joint.
• After opening, the tape slowly expands. Expansion is faster in warm temperatures.
• If necessary, surfaces can be primed to improve the tape's adhesion.
• Application temperature between +5°C and +30°C.
