GIB RocTape®



Bedding in tape to strengthen joints

A new way to reinforce plasterboard joints. 

GIB RocTape® is bedded in similar to GIB® Paper joint tape and can be installed using hand tools or mechanical tools. Both GIB RocTape® and GIB® Paper joint tape are approved for use in all GIB® Systems.

Jointing tapes are an important component in a GIB® System, providing critical strength between plasterboard sheets to aid in resisting structural movement and therefore it is important to select the most appropriate jointing tape for the application.

GIB RocTape® is a matt fibreglass tape that uses random fibre placement to achieve superior mechanical strength for flat joint applications. GIB® jointing compounds can permeate through the GIB RocTape® matt, creating a very strong joint through reinforcing the GIB® jointing compound. This means less cracking and cosmetic defects, resulting in fewer call backs, saving time and money.

A matt fibreglass joint tape (nonwoven) is very different in performance to the (woven) square mesh fibreglass joint tape. Some square mesh fibreglass tapes are pre-glued. The woven square mesh fibreglass joint tape is not recommended for reinforcing plasterboard joints by Winstone Wallboards and AS/NZS 2589-2017.

GIB RocTape® is suitable for flat plasterboard joints. 
For corner joints use GIB® Levelline®, GIB® Goldline™, GIB® UltraFlex®, or GIB® Paper joint tape.

GIB RocTape® advantages:

-      Makes the joint mechanically strong
-      Faster drying times
-      No entrapped air bubbles under the tape
-      No swelling or shrinkage due to water absorption
-      Eliminates inadequate compound under the joint tape, reducing tape adhesion failure
-      Coloured yellow for easy identification
