LEGAL WALL on plywood attached to the surface outside of the old school buildning. 5 different plywoods 4 good normal size piece and one smaller, window between that are not allowed to paint but no one seems to care if painted. Get there by bus or car, about 20min from Helsinki city center by car, bus longer. You can take bus from ITÄKESKUS too which takes about 25 min. Small town, 4minute walk from bus stop. Appoint the wall is a youth center where you can use toilet or ask for help.
Is this wall still safe to paint?
