painted

Hi The house we moved into several years ago has a composite door. The previous owner, who was terrible at diy, decided to paint the door. He painted what was a black door, red, which has now obviously faded. Any help on what I can do to remove it to get it back to black. Thanks

Hi We have a shared rendered wall at the back of our house. It is fairly new (year and half ish) but it is v patchy. We along with our neighbours want to paint it. I've contacted the chap that did the render and he thinks is was a standard mix of lime, sand, cement but also has cementone in it...
