Re-using concrete blocks

Conwex · 2021-02-23 21:36:19

Hi, I'm just wondering if I can reuse 4'' solid blocks to build some garden walls. The blocks were used for garden walls and have been painted a number of times.

Presumably the ends of the blocks will be very rough which should give a good base for the plaster. Surely a good scudding would be enough for the plaster, fix on a mesh is another option.
