Just not impressed with Dulux paint. Opacity is very low. Used 3 coats over a very faint patterned paper and it still shows through.
Don't forget a roller and tray. You don't want to be painting walls with a brush. Use the brush for cutting in to details/edges then roller the rest. Get the blue, low tack masking tape for easy removals. Screwfix and Toolstation also sell masking tape with plastic sheeting attached. It's great stuff for covering up.
If you can **** you can paint, don’t pay someone to do it unless you’re extremely busy.
Do you have wooden walls?
Yeh, straightforward and I'm rubbish at DIY masking tape Plastic sheets Set of different brushes Sandpaper and block possibly Screwfix is great if you have one near you Good luck
