It’s tempting to judge a paint job purely on the colour and the finish, but the quality of the preparation underneath is what actually determines how good it looks and how long it lasts. Skipping or rushing this stage is the most common reason a paint job disappoints.
Cracks and Holes Telegraph Through Paint
Even a thin coat of paint won’t hide a crack, dent or old filler that hasn’t been sanded flush. Left unaddressed, these imperfections become more obvious once the wall has a uniform colour and sheen, especially under direct light.
Cleaning and Degreasing Comes First
Dust, grease and nicotine staining all affect how well paint adheres and how true the final colour appears. Walls, especially in kitchens and hallways, need to be properly cleaned before any filler or primer goes on, otherwise paint can peel or the colour can look patchy.
Filling and Sanding Properly
Good filler work isn’t just about covering a hole — it’s about building it up in thin layers, letting each one dry, and sanding it back flush with the surrounding wall so there’s no visible ridge or dip once painted.
Priming Makes a Real Difference
New plaster, stained areas, and significant colour changes (particularly going from a dark colour to a light one) all benefit from a proper primer or mist coat. Skipping this step often means needing extra coats of the finish paint later to get full, even coverage — costing more time and paint overall.
What Good Preparation Typically Includes
- Cleaning and degreasing all surfaces
- Filling cracks, holes and old fixings
- Sanding filled areas flush with the wall
- Priming bare plaster or heavily stained surfaces
- Masking and protecting floors, fittings and furniture
A great paint job is built on preparation most people never notice — because it’s done properly.
