I am painting my home for the first time, as when I moved in two years ago it was a new build. The whole house is painted in a horrid creamily color and now I am starting to make my house look like a home, as I am a single parent of three girls ages from two years seven and a fourteen year old also currently unemployed.

I wanted to ask a couple of questions firstly. Do I need to apply an under coat or any other paint before I apply my colored emulsion to my walls? Also, I wanted to know is there a device, tool I can use for painting when I reach the corners? Where the two walls meet, they are getting painted different colors? I hope you can help as I have never painted anything before except my finger nails.
