Hi All I will be painting my house shortly and I have been quite overwhelmed by the number of different paint products out there. I will be painting internal (ceiling, walls, windows and doors). Just looking for white for both the ceilings and walls. From researching online I have found the following steps for painting a house: Sanding / scrape off rough surfaces Clean walls Fill in gaps Use Primer Use undercoat Paint topcoat My confusion at the moment is what products do I actually need to paint the house. Do I need both the primer and undercoat? I was at bunnings and noticed Dulux have a 1 step primer, sealer and undercoat. British paints have a 4 in 1 product. Are these suitable to use or should I just stick to a primer or just an undercoat? Do you use these for ceilings, walls, doors and windows? There are so many different ceiling and wall paints out there. What is a preferred brand that you use for ceilings and walls?
