UPDATE almost 2 years later: still great! Board holds up, no problems. And since I'm grinning like that , when I wipe the tile board the white part stays strong too!OVER my hundred year old chalkboards in my classroom.The pieces he is holding are approximately 40" x 70", one side taped to the back of the board and the other on the old board (we're not even talking about the GREEN board lol that stuff is really old) It sticks firmly and the board seems to be very securely attached once the velcro has been squeezed I will during the school year update if anyone is interested.Maybe there are other teachers considering a similar project.Sometimes a tiny crease appeared on the tape when peeled off the roll.But it smooths out en during application and were not a problem at all.
