Basically I have a large hall and very high stairwell covered with the dreaded wood chip that has been painted many times over the last 30 years. To make matters worst the walls are poor quality lattice plaster and if I attempt to remove the wood chip then the walls will then basically require being re-plastered. (This is something I want to avoid) Therefore has anyone used Graham & Brown 13130 Wall Doctor Wood chip Cover Paper or similar Wall Doctor Paper? I don’t expect it to be 100% perfect but at the same time I don’t want waste money on a product if it is useless. Any assistance is appreciated.
