Hello,
We have a brick retaining wall which is a garden bed- approx 1.1m tall and 30m long in an L shape. We want to cover it with blue board or similar and either render or do a textured paint finish. My question is- do we need to build out a little frame and attach the blue board to that (if so what are recommended dimensions of battens, distance between etc) or can we attach the blue board directly to the bricks (if so, with what fixing?). The retaining wall is not waterproofed and some dampness does come through the bricks.
Any advice welcome. Thanks
