CORRECT USE OF ARMA-CHEK D TAPES
The following procedures are applicable for Arma-Chek
self-adhesive matching tape with 20 mm, 50 mm and
100 mm width.
• Self-adhesive tapes are to be used for internal
applications only - do not use them on external
installations!!
• Check that the seams and joints are clean, dry and
free from contamination before applying the self
adhesive tape. To clean the seams and joints use the
Armafl ex cleaner.
• Peel back release paper and cover the entire seam
line with an additional 50 mm overlap where appli-
