Attaching this tape to a finished surface is not recommended.
However if you need to use tape on your concrete blocks choose a tape that is designed for concrete and will not interfere with other plans for your concrete blocks.
Concrete and concrete blocks are not designed to bond with tape.
If you plan to have the runner simply attached together you may want to consider the the roberts indoor pressure sensitive carpet seaming tape roll model 50 305.
