Yesterday I used some filler to fill some old holes left in my bedroom wall from the previous owner's shelf. All was well.
The paint they used is still here so today I sanded the wall smooth then painted over the top of the plaster (and yes I mixed the paint), even though it's covered, the paint however has turned out a lot darker then the rest of the room.
Should I have used a primer?
I'm very new to this DIY business.
Any feedback would be appreciated.
