Greetings, finally decided on going with the Glidden Diamond 450. However, the screen is already painted with a local Home Theater paint that I just did not like at all(2 coats primer, 3 coats top). Everything has been rolled on up to this point and I will roll the Glidden as well. Here are my questions:
1. Should I sand the wall currently? If so how aggressive? Do I sand the theater paint that is on there now all the way off, or just enough to get the wall smooth again?
2. Should I get an additional primer to put on before the Glidden goes on, if so what is recommended?
3. I have standard 3/16" nap rollers. Should I get a microfiber or synthetic one instead?
