FAQs on this product

How do I apply FibaTape?

FibaTape drywall tapes are self-adhesive fiberglass mesh tapes. As long as the surface is dry and dust free the tape will stick by pressing into place by hand or with a taping knife. The tape is now ready to be coated with joint compound.

Does FibaTape need to be embedded?

Yes. FibaTape has to be embedded in joint compound but not in the same manner as paper tape or FibaFuse tape. FibaTape is self-adhesive and should be pressed into place over the seams or in inside corners before any joint compound is applied. The compound is applied over the tape and because it is a mesh tape the compound actually is forced through the tape. This is one of the reasons for the popularity of FibaTape, the ability to put all the tape in place and then embed.

Where can I buy FibaTape?

FibaTape can be found at Home Depot, Lowes, Menards, Sherwin Williams, True Value,  Ace, Do-it-Best and other local hardware stores throughout US and Canada.  All products can also be found online for purchase.  Click here to visit our Where to Buy page.

Do I need to add thin set to each screw when using cement board and FibaTape?

Do you do not need to coat the screws holding the cement board in place because the screws are made special for attaching cement board. Do not use drywall screws. The screws do not have to set below the surface of the cement board, you should instead set the screws flush with the surface.

Does FibaTape meet ASTM Specifications?

Yes. FibaTape products meet the following ASTM standards: D-3775, C-474, D-17777, C-475 and D-3776. Other ASTM standards may be met with our specialty tape products.
