Any advice? We've had a new first floor extension built and the builders have done a good job. However, as I didn't specify old walls to be reskimmed, they did do several of the old walls. The walls aren't in a bad way, but have several holes from wall screws etc. I can fill them, but I know the wall will annoy me. Is there an easy way to reskim the wall smooth? I was wondering if any of the Polycell range are any good? Anyone used it? The basecoat variety... Anyone.. Thanks..
