Board Jointing Tape

OBEX CORTEX 0814 Board Jointing Tape is a single-sided adhesive tape used for sealing the joints between sheathing boards.  This tape has been specifically developed for use on surfaces such as Cement board, Calcium Silicate board, Gypsum board and many other surfaces.  It is reinforced with scrim to ensure maximum strength and durability across the lifetime of the bond.

OBEX CORTEX 0814 is highly resistant to both high and low temperature extremes, as well as exposure to UV and remains flexible across the lifetime of the product.  The unique acrylic dispersion adhesive maintains a high level of performance during exposure to moisture, increasing the lifetime of the seal, especially for construction materials subject to expansion and contraction.
