I'm about to paint my house on my own, everything's grey and I want to paint it white except for the kids bedroom, I know I have to wash the walls with sugar soap first, fill in any holes and cracks with fillers etc. But for some reason I'm scared to paint over the dark colour, anyone done this? Did you use primer first? And what brand paint did you buy? I'm thinking wickes/dulux. Arghh so much to do and learn!!
