Moss Graffiti on Concrete wall, Possible Damaging effects?
« on: March 11, 2014, 12:56:33 PM »
Hello!

I'm currently communicating with people at my school about doing a Moss Graffiti project on some Concrete walls. But some of the people in charge of the Walls are concerned about possible damage by the moss towards the concrete.. I have been unable to find any information about such things.. Do anyone hold a link to info on that or have own long term experience in such matters?
