I have a 17x14 game room with 10ft ceilings that I'm trying to convert
to a media room. It currently has a popcorn textured ceiling with
textured walls. I am going to paint the walls and ceiling. I've come
up with the following options.

1. Remove the popcorn from the ceiling and have a flat ceiling with
textured walls?
2. Remove the popcorn from the ceiling and flatten the walls so the
that the textures match? What would be the best way to remove the
texture from the walls?
3. Keep the popcorn, paint it with a sprayer and keep the textured
walls?

I'm trying to end up with a professional looking room and am looking
for some advice.

Thanks!
