Use Fiberglass Tape on Back Board Use Fiberglass Tape on Back Board
Use a fiberglass tape to installing backer board. Some people use paper tape or drywall tape, which may work, but will not withstand the wear and tear that will occur. When you install ceramic tile over the tape, it needs to be very strong fiberglass tape so that it will last. Ceramic will be very heavy, thus applying pressure to the tape.
