Old thread, but it fits my new problem:
Big box stores don't sell the wide alkali-resist tape, so I went to a real tile store that sells only tile and tiling accessories and asked for the 6" wide alkali-resist tape. The sales guy brought a roll from the warehouse and rang it up for about $17. After I got home, I took it out of the bag and did not see any labeling on it. I looked at the sales slip which described it as "fiberglass tape - suitable for redgard" and the word "TOLTAPERG". Is this really alkali-resist tape? It is white colored, but the 2" stuff is grey colored. That store does not sell drywall so that somewhat reassures me that it is not drywall tape.

I intend to use this tape to embed in thinset in the corners where CBU sheets meet, and to wrap it over the CBU that wraps over the vinyl liner over the curb and stick the tape down with thinset.

Use it or loose it?

Thanks for your advice.

Alkali Resistant Glass Scrim

Alkali Resistant (AR) Glass Scrim is an oriented fiber fabric. Scrims are often used in conjunction with fiber reinforced mixes to provide additional tensile strength in locations that will experience point-specific strain. When they are placed in the tensile regions of the product they can significantly increase the flexural strength of the composite. More than one layer of scrim can be used for increased performance.

This scrim is produced with 10mm X 10mm (3/8") webbing and comes in 1 m (40") wide rolls. It is available in lengths of 15', 50' and 300' (4.6 m, 15.2 m, 91.4 m).

All of our alkali resistant glass fiber products are manufactured in compliance with ASTM C1666/C 1666M, EN 15422 and under recommendations of PCI and GRCA.
