Hi, I have an old peeling wall at waist height, which I would like to re-finish or cover. My entire patio is tiled in white terrazzo and I’ll be painting this wall white. The top of the wall has a very uneven finish so I’d like to DIY cover/clad it in a thin waterproof white material rather than painting. Any ideas or products that would be suitable to DIY this? (Not tiling please!)
