Painting a room looks like the easiest home improvement there is. Buy paint, apply paint, done. It’s also the job most commonly redone within two years — because the visible part takes a weekend and the part that determines the result happens before the lid comes off.
Professional decorators spend roughly two-thirds of their time not painting. That ratio is the whole secret.

Preparation Is the Job
Clean the Surfaces
Paint bonds to what’s underneath it. Dust, grease and old cleaning residue all prevent adhesion. Kitchens and bathrooms especially need washing with sugar soap before anything else happens.
Fill and Sand
Fill cracks and holes, let the filler cure properly, then sand flush. Sand glossy surfaces to a dull finish so the new coat has something to grip. Wipe the dust off afterwards — sanding dust ruins more paint finishes than bad brushes do.
Mask Properly
Good masking tape, pressed down firmly along the edge, removed while the paint is still slightly soft. Tape pulled off fully dry takes the paint with it.
Choose the Right Paint for the Room
Finish matters more than colour for durability.
- Matt — hides wall imperfections well, marks easily, best for ceilings and low-traffic rooms
- Eggshell and satin — a gentle sheen with reasonable washability, good for most living spaces
- Semi-gloss and gloss — hard-wearing and wipeable, standard for woodwork, doors and trim
- Moisture-resistant — formulated for bathrooms and kitchens, worth the extra cost
The general rule: the more a surface gets touched, the more sheen it needs.
Don’t Skip the Primer
Primer isn’t an upsell. It’s necessary when you’re covering bare plaster, patched areas, stains, dark colours or glossy surfaces.
Painting a light colour over a dark one without primer typically takes four coats instead of two. Primer is cheaper than the paint you’d waste.
Test Colours Properly
Paint chips lie. Colour shifts dramatically with light, and a shade chosen under shop lighting often looks entirely different at home.
Paint a large sample patch — at least A4 size — on more than one wall. Look at it in morning light, afternoon light and under lamps at night. Give it two days before deciding.
Rooms facing away from the sun tend to make cool colours look cold and flat. Warmer undertones usually compensate.
Order of Work
Working in the right sequence saves an enormous amount of touching up:
- Ceiling first — spatter falls downwards
- Walls next
- Woodwork and trim last — skirting, architraves, doors and windows
- Cut in edges before rolling each wall, and keep a wet edge so the roller blends into fresh paint
Two thin coats always beat one thick one. Thick coats sag, dry unevenly and take longer to cure properly.
Tools Worth Paying For
A good brush holds more paint, releases it evenly and doesn’t shed bristles into the finish. A quality roller sleeve leaves less texture and covers faster.
Cheap tools cost more in extra coats and correction time than the money they save. A decent 2-inch angled sash brush will outlast a dozen bargain ones.
Let It Cure
Paint is touch-dry within hours but keeps hardening for two to four weeks. Until then it marks easily.
Reattach fittings gently, keep furniture slightly off freshly painted walls, and hold off on scrubbing anything for a month.
Do the preparation, use the right finish, work in order, and the result will still look intentional a decade from now.
